There’s a good bit riding on the second launch of Blue Origin’s New Glenn rocket.

Most directly, the fate of a NASA science mission to study Mars’ upper atmosphere hinges on a successful launch. The second flight of Blue Origin’s heavy-lifter will send two NASA-funded satellites toward the red planet to study the processes that drove Mars’ evolution from a warmer, wetter world to the cold, dry planet of today.

A successful launch would also nudge Blue Origin closer to winning certification from the Space Force to begin launching national security satellites.

But there’s more on the line. If Blue Origin plans to launch its first robotic Moon lander early next year—as currently envisioned—the company needs to recover the New Glenn rocket’s first stage booster. Crews will again dispatch Blue Origin’s landing platform into the Atlantic Ocean, just as they did for the first New Glenn flight in January.

The debut launch of New Glenn successfully reached orbit, a difficult feat for the inaugural flight of any rocket. But the booster fell into the Atlantic Ocean after three of the rocket’s engines failed to reignite to slow down for landing. Engineers identified seven changes to resolve the problem, focusing on what Blue Origin calls “propellant management and engine bleed control improvements.”

Relying on reuse

Pat Remias, Blue Origin’s vice president of space systems development, said Thursday that the company is confident in nailing the landing on the second flight of New Glenn. That launch, with NASA’s next set of Mars probes, is likely to occur no earlier than November from Cape Canaveral Space Force Station, Florida.

“We fully intend to recover the New Glenn first stage on this next launch,” Remias said in a presentation at the International Astronautical Congress in Sydney. “Fully intend to do it.”

Blue Origin, owned by billionaire Jeff Bezos, nicknamed the booster stage for the next flight “Never Tell Me The Odds.” It’s not quite fair to say the company’s leadership has gone all-in with their bet that the next launch will result in a successful booster landing. But the difference between a smooth touchdown and another crash landing will have a significant effect on Bezos’ Moon program.

That’s because the third New Glenn launch, penciled in for no earlier than January of next year, will reuse the same booster flown on the upcoming second flight. The payload on that launch will be Blue Origin’s first Blue Moon lander, aiming to become the largest spacecraft to reach the lunar surface. Ars has published a lengthy feature on the Blue Moon lander’s role in NASA’s effort to return astronauts to the Moon.

“We will use that first stage on the next New Glenn launch,” Remias said. “That is the intent. We’re pretty confident this time. We knew it was going to be a long shot [to land the booster] on the first launch.”

A long shot, indeed. It took SpaceX 20 launches of its Falcon 9 rocket over five years before pulling off the first landing of a booster. It was another 15 months before SpaceX launched a previously flown Falcon 9 booster for the first time.

With New Glenn, Blue’s engineers hope to drastically shorten the learning curve. Going into the second launch, the company’s managers anticipate refurbishing the first recovered New Glenn booster to launch again within 90 days. That would be a remarkable accomplishment.

Dave Limp, Blue Origin’s CEO, wrote earlier this year on social media that recovering the booster on the second New Glenn flight will “take a little bit of luck and a lot of excellent execution.”

On September 26, Blue Origin shared this photo of the second New Glenn booster on social media.

Blue Origin’s production of second stages for the New Glenn rocket has far outpaced manufacturing of booster stages. The second stage for the second flight was test-fired in April, and Blue completed a similar static-fire test for the third second stage in August. Meanwhile, according to a social media post written by Limp last week, the body of the second New Glenn booster is assembled, and installation of its seven BE-4 engines is “well underway” at the company’s rocket factory in Florida.

The lagging production of New Glenn boosters, known as GS1s (Glenn Stage 1s), is partly by design. Blue Origin’s strategy with New Glenn has been to build a small number of GS1s, each of which is more expensive and labor-intensive than SpaceX’s Falcon 9. This approach counts on routine recoveries and rapid refurbishment of boosters between missions.

However, this strategy comes with risks, as it puts the booster landings in the critical path for ramping up New Glenn’s launch rate. At one time, Blue aimed to launch eight New Glenn flights this year; it will probably end the year with two.

Laura Maginnis, Blue Origin’s vice president of New Glenn mission management, said last month that the company was building a fleet of “several boosters” and had eight upper stages in storage. That would bode well for a quick ramp-up in launch cadence next year.

However, Blue’s engineers haven’t had a chance to inspect or test a recovered New Glenn booster. Even if the next launch concludes with a successful landing, the rocket could come back to Earth with some surprises. SpaceX’s initial development of Falcon 9 and Starship was richer in hardware, with many boosters in production to decouple successful landings from forward progress.

Blue Moon

All of this means a lot is riding on an on-target landing of the New Glenn booster on the next flight. Separate from Blue Origin’s ambitions to fly many more New Glenn rockets next year, a good recovery would also mean an earlier demonstration of the company’s first lunar lander.

The lander set to launch on the third New Glenn mission is known as Blue Moon Mark 1, an unpiloted vehicle designed to robotically deliver up to 3 metric tons (about 6,600 pounds) of cargo to the lunar surface. The spacecraft will have a height of about 26 feet (8 meters), taller than the lunar lander used for NASA’s Apollo astronaut missions.

The first Blue Moon Mark 1 is funded from Blue Origin’s coffers. It is now fully assembled and will soon ship to NASA’s Johnson Space Center in Houston for vacuum chamber testing. Then, it will travel to Florida’s Space Coast for final launch preparations.

“We are building a series, not a singular lander, but multiple types and sizes and scales of landers to go to the Moon,” Remias said.

The second Mark 1 lander will carry NASA’s VIPER rover to prospect for water ice at the Moon’s south pole in late 2027. Around the same time, Blue will use a Mark 1 lander to deploy two small satellites to orbit the Moon, flying as low as a few miles above the surface to scout for resources like water, precious metals, rare Earth elements, and helium-3 that could be extracted and exploited by future explorers.

A larger lander, Blue Moon Mark 2, is in an earlier stage of development. It will be human-rated to land astronauts on the Moon for NASA’s Artemis program.

NASA’s other crew-rated lander will be derived from SpaceX’s Starship rocket. But Starship and Blue Moon Mark 2 are years away from being ready to accommodate a human crew, and both require orbital cryogenic refueling—something never before attempted in space—to transit out to the Moon.

This has led to a bit of a dilemma at NASA. China is also working on a lunar program, eyeing a crew landing on the Moon by 2030. Many experts say that, as of today, China is on pace to land astronauts on the Moon before the United States.

Of course, 12 US astronauts walked on the Moon in the Apollo program. But no one has gone back since 1972, and NASA and China are each planning to return to the Moon to stay.

One way to speed up a US landing on the Moon might be to use a modified version of Blue Origin’s Mark 1 lander, Ars reported Thursday.

If this is the path NASA takes, the stakes for the next New Glenn launch and landing will soar even higher.

No one will be able to sleep when the launch window opens, however.

Wiseman: About seven seconds prior to liftoff, the four main engines light, and they come up to full power. And then the solids light, and that’s when you’re going. What’s crazy to me is that it’s six and a half seconds into flight before the solids clear the top of the tower. Five million pounds of machinery going straight uphill. Six and a half seconds to clear the tower. As a human, I can’t wait to feel that force.

A little more than two minutes into flight, the powerful side-mounted boosters will separate. They will have done the vast majority of lifting to that point, with the rocket already reaching a velocity of 3,100 mph (5,000 kph) and an altitude of 30 miles (48 km), well on its way to space. As payload specialists, Koch and Hansen will largely be along for the ride. Wiseman, the commander, and Glover, the pilot, will be tracking the launch, although the rocket’s flight will be fully automated unless something goes wrong.

Wiseman: Victor and I, we have a lot of work. We have a lot of systems to monitor. Hopefully, everything goes great, and if it doesn’t, we’re very well-trained on what to do next.

After 8 minutes and 3 seconds, the rocket’s core stage will shut down, and the upper stage and Orion spacecraft will separate about 10 seconds later. They will be in space, with about 40 minutes to prepare for their next major maneuver.

In orbit

Koch: The wildest thing in this mission is that literally, right after main-engine cutoff, the first thing Jeremy and I do is get up and start working. I don’t know of a single other mission, certainly not in my memory, where that has been the case in terms of physical movement in the vehicle, setting things up.

Koch, Wiseman, and Glover have all flown to space before, either on a SpaceX Dragon or Russian Soyuz vehicle, and spent several months on the International Space Station. So they know how their bodies will react to weightlessness. Nearly half of all astronauts experience “space adaptation syndrome” during their first flight to orbit, and there is really no way to predict who it will afflict beforehand. This is a real concern for Hansen, a first-time flier, who is expected to hop out of his seat and start working.

Hansen: I’m definitely worried about that, just from a space motion sickness point of view. So I’ll just be really intentional. I won’t move my head around a lot. Obviously, I’m gonna have to get up and move. And I’ll just be very intentional in those first few hours while I’m moving around. And the other thing that I’ll do—it’s very different from Space Station—is I just have everything memorized, so I don’t have to read the procedure on those first few things. So I’m not constantly going down to the [tablet] and reading, and then up. And I’ll just try to minimize what I do.

Koch and Hansen will set up and test essential life support systems on the spacecraft because if the bathroom does not work, they’re not going to the Moon.

Hansen: We kind of split the vehicle by side. So Christina is on the side of the toilet. She’s taking care of all that stuff. I’m on the side of the water dispenser, which is something they want to know: Can we dispense water? It’s not a very complicated system. We just got to get up, get the stuff out of storage, hook it up. I’ll have some camera equipment that I’ll pull out of there. I’ve got the masks we use if we have a fire and we’re trying to purge the smoke. I’ve got to get those set up and make sure they’re good to go. So it’s just little jobs, little odds and ends.

Unlike a conventional rocket mission, Artemis II vehicle’s upper stage, known as the Interim Cryogenic Propulsion Stage, will not fire right away. Rather, after separating from the core stage, Orion will be in an elliptical orbit that will take it out to an apogee of 1,200 nautical miles, nearly five times higher than the International Space Station. There, the crew will be further from Earth than anyone since the Apollo program.

Welcome to Edition 8.12 of the Rocket Report! We often hear from satellite operators—from the military to venture-backed startups—about their appetite for more launch capacity. With so many rocket launches happening around the world, some might want to dismiss these statements as a corporate plea for more competition, and therefore lower prices. SpaceX is on pace to launch more than 150 times this year. China could end the year with more than 70 orbital launches. These are staggering numbers compared to global launch rates just a few years ago. But I’m convinced there’s room for more alternatives for reliable (and reusable) rockets. All of the world’s planned mega-constellations will need immense launch capacity just to get off the ground, and if successful, they’ll go into regular replacement and replenishment cycles. Throw in the still-undefined Golden Dome missile shield and many nations’ desire for a sovereign launch capability, and it’s easy to see the demand curve going up.

Sharp words from Astra’s Chris Kemp. Chris Kemp, the chief executive officer of Astra, apparently didn’t get the memo about playing nice with his competitors in the launch business. Kemp made some spicy remarks at the Berkeley Space Symposium 2025 earlier this month, billed as the largest undergraduate aerospace event at the university (see video of the talk). During the speech, Kemp periodically deviated from building up Astra to hurling insults at several of his competitors in the launch industry, Ars reports. To be fair to Kemp, some of his criticisms are not without a kernel of truth. But they are uncharacteristically rough all the same, especially given Astra’s uneven-at-best launch record and financial solvency to date.

Wait, what?! … Kemp is generally laudatory in his comments about SpaceX, but his most crass statement took aim at the quality of life of SpaceX employees at Starbase, Texas. He said life at Astra is “more fun than SpaceX because we’re not on the border of Mexico where they’ll chop your head off if you accidentally take a left turn.” For the record, no SpaceX employees have been beheaded. “And you don’t have to live in a trailer. And we don’t make you work six and a half days a week, 12 hours a day.” Kemp also accused Firefly Aerospace of sending Astra “garbage” rocket engines as part of the companies’ partnership on propulsion for Astra’s next-generation rocket.

A step forward for Europe’s reusable rocket program. No one could accuse the European Space Agency and its various contractors of moving swiftly when it comes to the development of reusable rockets. However, it appears that Europe is finally making some credible progress, Ars reports. Last week, the France-based ArianeGroup aerospace company announced that it completed the integration of the Themis vehicle, a prototype rocket that will test various landing technologies, on a launch pad in Sweden. Low-altitude hop tests, a precursor for developing a rocket’s first stage that can vertically land after an orbital launch, could start late this year or early next.

Hopping into the future … “This milestone marks the beginning of the ‘combined tests,’ during which the interface between Themis and the launch pad’s mechanical, electrical, and fluid systems will be thoroughly trialed, with the aim of completing a test under cryogenic conditions,” ArianeGroup said. This particular rocket will likely undergo only short hops, initially about 100 meters. A follow-up vehicle, Themis T1E, is intended to fly medium-altitude tests at a later date. Some of the learnings from these prototypes will feed into a smaller, reusable rocket intended to lift 500 kilograms to low-Earth orbit. This is under development by MaiaSpace, a subsidiary of ArianeGroup. Eventually, the European Space Agency would like to use technology developed as part of Themis to develop a new line of reusable rockets that will succeed the Ariane 6 rocket.

Navy conducts Trident missile drills. The US Navy carried out four scheduled missile tests of a nuclear-capable weapons system off the coast of Florida within the last week, Defense News reports. The service’s Strategic Systems Programs conducted flights of unarmed Trident II D5 Life Extension missiles from a submerged Ohio-class ballistic missile submarine from September 17 to September 21 as part of an ongoing scheduled event meant to test the reliability of the system. “The missile tests were not conducted in response to any ongoing world events,” a Navy release said.

Secret with high visibility … The Navy periodically performs these Trident missile tests off the coasts of Florida and California, taking advantage of support infrastructure and range support from the two busiest US spaceports. The military doesn’t announce the exact timing of the tests, but warnings issued for pilots to stay out of the area give a general idea of when they might occur. One of the launch events Sunday was visible from Puerto Rico, illuminating the night sky in photos published on social media. The missiles fell in the Atlantic Ocean as intended, the Navy said. The Trident II D5 missiles were developed in the 1980s and are expected to remain in service on the Navy’s ballistic missile submarines into the 2040s. The Trident system is one leg of the US military’s nuclear triad, alongside land-based Minuteman ballistic missiles and nuclear-capable strategic bombers. (submitted by EllPeaTea)

Firefly plans for Alpha’s return to flight. Firefly Aerospace expects to resume Alpha launches in the “coming weeks,” with two flights planned before the end of the year, Space News reports. These will be the first flights of Firefly’s one-ton-class Alpha rocket since a failure in April destroyed a Lockheed Martin tech demo satellite after liftoff from California. In a quarterly earnings call, Firefly shared a photo showing its next two Alpha rockets awaiting shipment from the company’s Texas factory.

Righting the ship … These next two launches really need to go well for Firefly. The Alpha rocket has, at best, a mixed record with only two fully successful flights in six attempts. Two other missions put their payloads into off-target orbits, and two Alpha launches failed to reach orbit at all. Firefly went public on the NASDAQ stock exchange last month, raising nearly $900 million in the initial public offering to help fund the company’s future programs, namely the medium-lift Eclipse rocket developed in partnership with Northrop Grumman. There’s a lot to like about Firefly. The company achieved the first fully successful landing of a commercial spacecraft on the Moon in March. NASA has selected Firefly for three more commercial landings on the Moon, and Firefly reported this week it has an agreement with an unnamed commercial customer for an additional dedicated mission. But the Alpha program hasn’t had the same level of success. We’ll see if Firefly can get the rocket on track soon. (submitted by EllPeaTea)

Avio wins contract to launch “extra-European” mission. Italian rocket builder Avio has signed a launch services agreement with US-based launch aggregator SpaceLaunch for a Vega C launch carrying an Earth observation satellite for an “extra-European institutional customer” in 2027, European Spaceflight reports. Avio announced that it had secured the launch contract on September 18. According to the company, the contract was awarded through an open international competition, with Vega C chosen for its “versatility and cost-effectiveness.” While Avio did not reveal the identity of the “extra-European” customer, it said that it would do so later this year.

Plenty of peculiarities … There are several questions to unpack here, and Andrew Parsonson of European Spaceflight goes through them all. Presumably, extra-European means the customer is based outside of Europe. Avio’s statement suggests we’ll find out the answer to that question soon. Details about the US-based launch broker SpaceLaunch are harder to find. SpaceLaunch appears to have been founded in January 2025 by two former Firefly Aerospace employees with a combined 40 years of experience in the industry. On its website, the company claims to provide end-to-end satellite launch integration, mission management, and launch procurement services with a “portfolio of launch vehicle capacity around the globe.” SpaceLaunch boasts it has supported the launch of more than 150 satellites on 12 different launch vehicles. However, according to public records, it does not appear that the company itself has supported a single launch. Instead, the claim seems to credit SpaceLaunch with launches that were actually carried out during the two founders’ previous tenures at Spaceflight, Firefly Aerospace, Northrop Grumman, and the US Air Force.

Falcon 9 launches three missions for NASA and NOAA. Scientists loaded three missions worth nearly $1.6 billion on a SpaceX Falcon 9 rocket for launch Wednesday, toward an orbit nearly a million miles from Earth, to measure the supersonic stream of charged particles emanating from the Sun, Ars reports. One of the missions, from the National Oceanic and Atmospheric Administration (NOAA), will beam back real-time observations of the solar wind to provide advance warning of geomagnetic storms that could affect power grids, radio communications, GPS navigation, air travel, and satellite operations. The other two missions come from NASA, with research objectives that include studying the boundary between the Solar System and interstellar space and observing the rarely seen outermost layer of our own planet’s atmosphere.

Immense value …All three spacecraft will operate in orbit around the L1 Lagrange point, a gravitational balance point located more than 900,000 miles (1.5 million kilometers) from Earth. Bundling these three missions onto the same rocket saved at least tens of millions of dollars in launch costs. Normally, they would have needed three different rockets. Rideshare missions to low-Earth orbit are becoming more common, but spacecraft departing for more distant destinations like the L1 Lagrange point are rare. Getting all three missions on the same launch required extensive planning, a stroke of luck, and fortuitous timing. “This is the ultimate cosmic carpool,” said Joe Westlake, director of NASA’s heliophysics division. “These three missions heading out to the Sun-Earth L1 point riding along together provide immense value for the American taxpayer.”

US officials concerned about China mastering reusable launch. SpaceX’s dominance in reusable rocketry is one of the most important advantages the United States has over China as competition between the two nations extends into space, US Space Force officials said Monday. But several Chinese companies are getting close to fielding their own reusable rockets, Ars reports. “It’s concerning how fast they’re going,” said Brig. Gen. Brian Sidari, the Space Force’s deputy chief of space operations for intelligence. “I’m concerned about when the Chinese figure out how to do reusable lift that allows them to put more capability on orbit at a quicker cadence than currently exists.”

By the numbers … China has used 14 different types of rockets on its 56 orbital-class missions this year, and none have flown more than 11 times. Eight US rocket types have cumulatively flown 145 times, with 122 of those using SpaceX’s workhorse Falcon 9. Without a reusable rocket, China must maintain more rocket companies to sustain a launch rate of just one-third to one-half that of the United States. This contrasts with the situation just four years ago, when China outpaced the United States in orbital rocket launches. The growth in US launches has been a direct result of SpaceX’s improvements to launch at a higher rate, an achievement primarily driven by the recovery and reuse of Falcon 9 boosters and payload fairings.

Atlas V launches more Kuiper satellites. Roughly an hour past sunrise Thursday, an Atlas V rocket from United Launch Alliance took flight from Cape Canaveral Space Force Station, Florida. Onboard the rocket, flying in its most powerful configuration, were the next 27 Project Kuiper broadband satellites from Amazon, Spaceflight Now reports. This is the third batch of production satellites launched by ULA and the fifth overall for the growing low-Earth orbit constellation. The Atlas V rocket released the 27 Kuiper satellites about 280 miles (450 kilometers) above Earth. The satellites will use onboard propulsion to boost themselves to their assigned orbit at 392 miles (630 kilometers).

Another Kuiper launch on tap … With this deployment, Amazon now has 129 satellites in orbit. This is a small fraction of the network’s planned total of 3,232 satellites, but Amazon has enjoyed a steep ramp-up in the Kuiper launch cadence as the company’s satellite assembly line in Kirkland, Washington, continues churning out spacecraft. Another 24 Kuiper satellites are slated to launch September 30 on a SpaceX Falcon 9 rocket, and Amazon has delivered enough satellites to Florida for an additional launch later this fall.

German military will fly with Ariane 6. Airbus Defense and Space has awarded Arianespace a contract to launch a pair of SATCOMBw-3 communications satellites for the German Armed Forces, European Spaceflight reports. Airbus is the prime contractor for the nearly $2.5 billion (2.1 billion euro) SATCOMBw-3 program, which will take over from the two-satellite SATCOMBw-2 constellation currently providing secure communications for the German military. Arianespace announced Wednesday that it had been awarded the contract to launch the satellites aboard two Ariane 6 rockets. “By signing this new strategic contract for the German Armed Forces, Arianespace accomplishes its core mission of guaranteeing autonomous access to space for European sovereign satellites,” said Arianespace CEO David Cavaillolès.

Running home to Europe … The chief goal of the Ariane 6 program is to provide Europe with independent access to space, something many European governments see as a strategic requirement. Several European military, national security, and scientific satellites have launched on SpaceX Falcon 9 rockets in the last few years as officials waited for the debut of the Ariane 6 rocket. With three successful Ariane 6 flights now in the books, European customers seem to now have the confidence to commit to flying their satellites on Ariane 6. (submitted by EllPeaTea)

Artemis II launch targeted for February. NASA is pressing ahead with preparations for the first launch of humans beyond low-Earth orbit in more than five decades, and officials said Tuesday that the Artemis II mission could take flight early next year, Ars reports. Although work remains to be done, the space agency is now pushing toward a launch window that opens on February 5, 2026, officials said during a news conference on Tuesday at Johnson Space Center. The Artemis II mission represents a major step forward for NASA and seeks to send four astronauts—Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen—around the Moon and back. The 10-day mission will be the first time astronauts have left low-Earth orbit since the Apollo 17 mission in December 1972.

Orion named Integrity … The first astronauts set to fly to the Moon in more than 50 years will do so in Integrity, Ars reports. NASA’s Artemis II crew revealed Integrity as the name of their Orion spacecraft during a news conference on Wednesday at the Johnson Space Center in Houston. “We thought, as a crew, we need to name this spacecraft. We need to have a name for the Orion spacecraft that we’re going to ride this magical mission on,” said Wiseman, commander of the Artemis II mission.

FAA reveals new Starship trajectories. Sometime soon, perhaps next year, SpaceX will attempt to fly one of its enormous Starship rockets from low-Earth orbit back to its launch pad in South Texas. A successful return and catch at the launch tower would demonstrate a key capability underpinning Elon Musk’s hopes for a fully reusable rocket. In order for this to happen, SpaceX must overcome the tyranny of geography. A new document released by the Federal Aviation Administration shows the narrow corridors Starship will fly to space and back when SpaceX tries to recover them, Ars reports.

Flying over people … It was always evident that flying a Starship from low-Earth orbit back to Starbase would require the rocket to fly over Mexico and portions of South Texas. The rocket launches to the east over the Gulf of Mexico, so it must approach Starbase from the west when it comes in for a landing. The new maps show SpaceX will launch Starships to the southeast over the Gulf and the Caribbean Sea, and directly over Jamaica, or to the northeast over the Gulf and the Florida peninsula. On reentry, the ship will fly over Baja California and Mexico’s interior near the cities of Hermosillo and Chihuahua, each with a population of roughly a million people. The trajectory would bring Starship well north of the Monterrey metro area and its 5.3 million residents, then over the Rio Grande Valley near the Texas cities of McAllen and Brownsville.

New Glenn’s second flight at least a month away. The second launch of Blue Origin’s New Glenn rocket, carrying a NASA smallsat mission to Mars, is now expected in late October or early November, Space News reports. Tim Dunn, NASA’s senior launch director at Kennedy Space Center, provided an updated schedule for the second flight of New Glenn in comments after a NASA-sponsored launch on a Falcon 9 rocket Wednesday. Previously, the official schedule from NASA showed the launch date as no earlier than September 29.

No surprise … It was already apparent that this launch wouldn’t happen September 29. Blue Origin has test-fired the second stage for the upcoming flight of the New Glenn rocket but hasn’t rolled the first stage to the launch pad for its static fire. Seeing the rocket emerge from Blue’s factory in Florida will be an indication that the launch date is finally near. Blue Origin will launch NASA’s ESCAPADE mission, a pair of small satellites to study how the solar wind interacts with the Martian upper atmosphere.

Blue Origin will launch a NASA rover to the Moon. NASA has awarded Blue Origin a task order worth up to $190 million to deliver its Volatiles Investigating Polar Exploration Rover (VIPER) to the Moon’s surface, Aviation Week & Space Technology reports. Blue Origin, one of 13 currently active Commercial Lunar Payload Services (CLPS) providers, submitted the only bid to carry VIPER to the Moon after NASA requested offers from industry last month. NASA canceled the VIPER mission last year, citing cost overruns with the rover and delays in its planned ride to the Moon aboard a lander provided by Astrobotic. But engineers had already completed assembly of the rover, and scientists protested NASA’s decision to terminate the mission.

Some caveats … Blue Origin will deliver VIPER to a location near the Moon’s south pole in late 2027 using a robotic Blue Moon MK1 lander, a massive craft larger than the Apollo lunar landing module. The company’s first Blue Moon MK1 lander is scheduled to fly to the Moon next year. NASA’s contract for the VIPER delivery calls for Blue Origin to design accommodations for the rover on the Blue Moon lander. The agency said it will decide whether to proceed with the actual launch on a New Glenn rocket and delivery of VIPER to the Moon based partially on the outcome of the first Blue Moon test flight next year.

Whole and undivided

Ultimately, Integrity was inspired by something one of their instructors said while on a team-building trip to Iceland.

“He coined this for us, and we held on to it,” said Hansen, who, unlike his NASA crewmates, is a Canadian Space Agency astronaut. “It was this idea that you’re not a person who has integrity, you’re a person who strives to be in integrity. Sometimes you’re out of integrity, and sometimes you’re in your integrity. That was profound for all of us.”

For Glover, it boiled down to the definition.

“The Latin root means ‘whole.’ It’s a very simple concept, and it’s about being whole. This crew comes together as pieces—the four of us and our backups—but the six of us make up a whole team. The vehicle, the pieces come together and make up a whole spacecraft,” he said.

“What people anecdotally say is that integrity is what you do when no one’s watching. That, and truth, honor, and integrity matter,” said Glover. “There are so many layers to that name and what it means and what it inspires.”

Integrating Integrity

Integrity is one of the tenets of the Astronaut Code of Professional Responsibility. It is also one of the Canadian Space Agency’s core values.

“We all strive to be in integrity all of the time, but integrity isn’t an absolute that you either have or don’t have,” said Koch. “So this helps us give grace and build trust with each other.”

“I hope that people hearing [the name] over the 10 days of the mission appreciate all of the different things that it means, from a whole ship, a whole crew, to a wholeness and wellness that I think humanity just needs. We need to hear more of that togetherness and wholeness,” said Glover.

Now that it has been announced, next up is for Integrity to be used as the crew’s possible call sign.

“We waited to make sure the whole enterprise was ready for us to announce it before we even used it,” said Glover. “I think we’ll start using it in sims: ‘Houston, Integrity. Integrity, Houston.’ That’s the plan.

“But if someone doesn’t like that, then we won’t, and we can say Orion,” he said.

A Japanese lander crashed on the Moon after losing track of its location

“It’s not impossible, so how do we overcome our hurdles?”

A robotic lander developed by a Japanese company named ispace plummeted to the Moon’s surface Thursday, destroying a small rover and several experiments intended to demonstrate how future missions could mine and harvest lunar resources.

Ground teams at ispace’s mission control center in Tokyo lost contact with the Resilience lunar lander moments before it was supposed to touch down in a region called Mare Frigoris, or the Sea of Cold, a basaltic plain in the Moon’s northern hemisphere.

A few hours later, ispace officials confirmed what many observers suspected. The mission was lost. It’s the second time ispace has failed to land on the Moon in as many tries.

“We wanted to make Mission 2 a success, but unfortunately we haven’t been able to land,” said Takeshi Hakamada, the company’s founder and CEO.

Ryo Ujiie, ispace’s chief technology officer, said the final data received from the Resilience lander—assuming it was correct—showed it at an altitude of approximately 630 feet (192 meters) and descending too fast for a safe landing. “The deceleration was not enough. That was a fact,” Ujiie told reporters in a press conference. “We failed to land, and we have to analyze the reasons.”

The company said in a press release that a laser rangefinder used to measure the lander’s altitude “experienced delays in obtaining valid measurement values.” The downward-facing laser fires light pulses toward the Moon during descent, and clocks the time it takes to receive a reflection. This time delay at light speed tells the lander’s guidance system how far it is above the lunar surface. But something went wrong in the altitude measurement system on Thursday.

“As a result, the lander was unable to decelerate sufficiently to reach the required speed for the planned lunar landing,” ispace said. “Based on these circumstances, it is currently assumed that the lander likely performed a hard landing on the lunar surface.”

Controllers sent a command to reboot the lander in hopes of reestablishing communication, but the Resilience spacecraft remained silent.

“Given that there is currently no prospect of a successful lunar landing, our top priority is to swiftly analyze the telemetry data we have obtained thus far and work diligently to identify the cause,” Hakamada said in a statement. “We will strive to restore trust by providing a report of the findings to our shareholders, payload customers, Hakuto-R partners, government officials, and all supporters of ispace.”

Overcoming obstacles

The Hakuto name harkens back to ispace’s origin in 2010 as a contender for the Google Lunar X-Prize, a sweepstakes that offered a $20 million grand prize to the first privately funded team to put a lander on the Moon. Hakamada’s group was called Hakuto, which means “white rabbit” in Japanese. The prize shut down in 2018 without a winner, leading some of the teams to dissolve or find new purpose. Hakamada stayed the course, raised more funding, and rebooted the program under the name Hakuto-R.

It’s a story of resilience, hence the name of ispace’s second lunar lander. The mission made it closer to the Moon than the ispace’s first landing attempt in 2023, but Thursday’s failure is a blow to Hakamada’s project.

“As a fact, we tried twice and we haven’t been able to land on the Moon,” Hakamada said through an interpreter. “So we have to say it’s hard to land on the Moon, technically. We know it’s not easy. It’s not something that everyone can do. We know it’s hard, but the important point is it’s not impossible. The US private companies have succeeded in landing, and also JAXA in Japan has succeeded in landing, so it’s not impossible. So how do we overcome our hurdles?”

In April 2023, ispace’s first lander crashed on the Moon due to a similar altitude measurement problem. The spacecraft thought it was on the surface of the Moon, but was actually firing its engine to hover at an altitude of 3 miles (5 kilometers). The spacecraft ran out of fuel and went into a free fall before impacting the Moon.

Engineers blamed software as the most likely reason for the altitude-measurement problem. During descent, ispace’s lander passed over a 10,000-foot-tall (3,000-meter) cliff, and the spacecraft’s computer interpreted the sudden altitude change as erroneous.

Ujiie, who leads ispace’s technical teams, said the failure mode Thursday was “similar” to that of the first mission two years ago. But at least in ispace’s preliminary data reviews, engineers saw different behavior from the Resilience lander, which flew with a new type of laser rangefinder after ispace’s previous supplier stopped producing the device.

“From Mission 1 to Mission 2, we improved the software,” Ujiie said. “Also, we improved how to approach the landing site… We see different phenomena from Mission 1, so we have to do more analysis to give you any concrete answers.”

If ispace landed smoothly on Thursday, the Resilience spacecraft would have deployed a small rover developed by ispace’s European subsidiary. The rover was partially funded by the Luxembourg Space Agency with support from the European Space Agency. It carried a shovel to scoop up a small amount of lunar soil and a camera to take a photo of the sample. NASA had a contract with ispace to purchase the lunar soil in a symbolic proof of concept to show how the government might acquire material from commercial mining companies in the future.

The lander also carried a water electrolyzer experiment to demonstrate technologies that could split water molecules into hydrogen and oxygen, critical resources for a future Moon base. Other payloads aboard the Resilience spacecraft included cameras, a food production experiment, a radiation monitor, and a Swedish art project called “MoonHouse.”

The spacecraft chassis used for ispace’s first two landing attempts was about the size of a compact car, with a mass of about 1 metric ton (2,200 pounds) when fully fueled. The company’s third landing attempt is scheduled for 2027 with a larger lander. Next time, ispace will fly to the Moon in partnership between the company’s US subsidiary and Draper Laboratory, which has a contract with NASA to deliver experiments to the lunar surface.

Track record

The Resilience lander launched in January on top of a SpaceX Falcon 9 rocket, riding to space in tandem with a commercial Moon lander named Blue Ghost from Firefly Aerospace. Firefly’s lander took a more direct journey to the Moon and achieved a soft landing on March 2. Blue Ghost operated on the lunar surface for two weeks and completed all of its objectives.

The trajectory of ispace’s lander was slower, following a lower-energy, more fuel-efficient path to the Moon before entering lunar orbit last month. Once in orbit, the lander made a few more course corrections to line up with its landing site, then commenced its final descent on Thursday.

Thursday’s landing attempt was the seventh time a privately developed Moon lander tried to conduct a controlled touchdown on the lunar surface.

Two Texas-based companies have had the most success. One of them, Houston-based Intuitive Machines, landed its Odysseus spacecraft on the Moon in February 2024, marking the first time a commercial lander reached the lunar surface intact. But the lander tipped over after touchdown, cutting its mission short after achieving some limited objectives. A second Intuitive Machines lander reached the Moon in one piece in March of this year, but it also fell over and didn’t last as long as the company’s first mission.

Firefly’s Blue Ghost operated for two weeks after reaching the lunar surface, accomplishing all of its objectives and becoming the first fully successful privately owned spacecraft to land and operate on the Moon.

Intuitive Machines, Firefly, and a third company—Astrobotic Technology—have launched their lunar missions under contract with a NASA program aimed at fostering a commercial marketplace for transportation to the Moon. Astrobotic’s first lander failed soon after its departure from Earth. The first two missions launched by ispace were almost fully private ventures, with limited participation from the Japanese space agency, Luxembourg, and NASA.

Commercial travel to the Moon only began in 2019, so there’s not much of a track record to judge the industry’s prospects. When NASA started signing contracts for commercial lunar missions, the then-chief of the agency’s science vision, Thomas Zurbuchen, estimated the initial landing attempts would have a 50-50 chance of success. On the whole, NASA’s experience with Intuitive Machines, Firefly, and Astrobotic isn’t too far off from Zurbuchen’s estimate, with one full success and a couple of partial successes.

The commercial track record worsens if you include private missions from ispace and Israel’s Beresheet lander.

But ispace and Hakamada haven’t given up on the dream. The company’s third mission will launch under the umbrella of the same NASA program that contracted with Intuitive Machines, Firefly, and Astrobotic. Hakamada cited the achievements of Firefly and Intuitive Machines as evidence that the commercial model for lunar missions is a valid one.

“The ones that have the landers, there are two companies I mentioned. Also, Blue Origin maybe coming up. Also, ispace is a possibility,” Hakamada said. “So, very few companies. We would like to catch up as soon as possible.”

It’s too early to know how the failure on Thursday might impact ispace’s next mission with Draper and NASA.

“I have to admit that we are behind,” said Jumpei Nozaki, director and chief financial officer at ispace. “But we do not really think we are behind from the leading group yet. It’s too early to decide that. The players in the world that can send landers to the Moon are very few, so we still have some competitive edge.”

“Honestly, there were some times I almost cried, but I need to lead this company, and I need to have a strong will to move forward, so it’s not time for me to cry,” Hakamada said.

Blue Origin boss: Government should forget launch and focus on “exotic” missions

Eighteen months after leaving his job as a vice president at Amazon to take over as Blue Origin’s chief executive, Dave Limp has some thoughts on how commercial companies and government agencies like NASA should explore the Solar System together.

Limp had no background in the space industry before taking the helm of Jeff Bezos’ space company in December 2023. He started his career as a computer scientist at Apple, took a stint at a venture capital firm, and joined Amazon in 2010, where he managed development of consumer devices like Alexa, Kindle, and the Fire TV.

“I had no thoughts of ever running a space company,” Limp said Thursday at a space conference in Washington, DC. “I’ve done consumer electronics my whole life. Started at Apple and did a bunch of other things, and so when I decided to retire from Amazon, I was looking for something that I could give back a little bit, be a little bit more philanthropic in the sort of second half of my career. I didn’t want to stop working, just wanted to do something different. And about that same time, Jeff was looking for a CEO.”

While he’s still a relative newcomer to the space business, Limp’s views align with those of many policy wonks and industry leaders who have the ears of senior officials in the Trump administration, including Jared Isaacman, President Trump’s nominee to become the next NASA administrator. Limp’s long tenure at Amazon and his selection as Blue Origin’s new CEO demonstrate that he also has the trust of Bezos, who was dissatisfied with his company’s slow progress in spaceflight.

“I think Jeff convinced me, and he’s very persuasive, that Blue didn’t need another rocket scientist,” Limp said. “We have thousands of the world’s best rocket scientists. What we needed was a little bit more decisiveness, a little bit more ability to think about: How do we manufacture at scale? And those are things I’ve done in the past, and so I’ve never looked back.”

Leave it to us

In remarks Thursday at the Humans to the Moon & Mars Summit, Limp advocated for commercial companies, like his own, taking a larger role in developing the transportation and infrastructure to meet lofty national objectives established by government leaders.

In some ways, NASA has long been moving in this direction, beginning with initiatives ceding most launch services to private industry in the 1990s. More recently, NASA has turned to commercial companies for crew and cargo deliveries to the International Space Station and cargo and human-rated Moon landers.

However, NASA, with the backing of key congressional leaders, has held an iron grip on having its own heavy-lift launcher and crew capsule to ferry astronauts between Earth and destinations beyond low-Earth orbit. Now, these vehicles—the Space Launch System and Orion spacecraft—may be canceled if Congress agrees with Trump’s proposed NASA budget.

Commercial rockets close to matching or exceeding the Space Launch System’s lift capability are available for purchase or likely will be soon. These include SpaceX’s Starship mega-rocket and Blue Origin’s New Glenn launcher. Both are already key elements of NASA’s Artemis program, which aims to land US astronauts on the Moon as a stepping stone toward human expeditions to Mars.

But NASA still plans to use its government-owned Space Launch System rocket and Orion spacecraft to transport astronauts out to the Moon, where they will rendezvous with a Starship or Blue Origin’s Blue Moon lander to fly to and from the lunar surface.

SLS and Orion are expensive vehicles, costing more than $4 billion per launch for the initial set of four Artemis missions, according to a report by NASA’s inspector general. While commercial companies like Boeing, Lockheed Martin, and Northrop Grumman build elements of SLS and Orion, NASA acts as the prime integrator. The agency signed cost-plus contracts with the companies building SLS and Orion, meaning the government is on the hook for cost overruns. And there have been many.

NASA’s robotic science probes are also getting more expensive, even when accounting for inflation. Given the way NASA procures science probes, it would cost NASA more today to send an orbiter to Mars than it did for a similarly sized spacecraft a quarter-century ago.

This has to change in order for NASA and private companies like Blue Origin and SpaceX to make their ambitions a reality, Limp said Thursday.

“I think commercial folks can worry about the infrastructure,” he said. “We can do the launch. We can build the satellite buses that can get you to Mars much more frequently, that don’t cost billions of dollars. We can take a zero, and over time, maybe two zeros off of that. And if the governments around the world leave that to the commercial side, then there are a lot more resources that are freed up for the science side, for the national prestige side, and those types of things.”

The bottom line

Limp followed these comments with a dose of realism you don’t often hear from space industry executives. While there’s a growing list of commercially viable markets in space (things like Starlink and satellite servicing wouldn’t have been money-makers 20 years ago), the market for human spaceflight still requires some level of government commitment.

“I think the thing about bringing commercial aspects to exploration, to science, to the Moon, to Mars, is that we have to see a business prospect for it,” Limp said. “We have to turn it into a business, and that benefits American taxpayers because we will use that capital as efficiently as we can to get to the Moon, to get to Mars in a safe way, but in a way that’s the most efficient.

“We’re committed to that, no matter what the architecture looks like, but it does take the US government and international governments to have the motivation to do it,” he continued. “There’s not yet a commercial reason only to go to the Moon with humans. There are lots of commercial reasons to put robotics on the Moon and other types of things. So, we do need to have conviction that the Moon is important and Mars is important as well.”

Trump and Musk, an ally and advisor to the president, rekindled the question of Moon or Mars in a series of remarks during the early weeks of the new Trump administration. The Artemis Moon program began during the first Trump administration, with the goal of returning astronauts to the Moon for the first time since 1972. NASA would establish a sustained presence at the Moon, using our nearest planetary body as a proving ground for the next destination for humans in Solar System exploration: Mars.

SpaceX’s Starship, while capable of one day landing on the Moon, was designed for long-duration cruises to Mars. Blue Origin’s Blue Moon is tailored for lunar landings.

“As an American, I don’t want another Sputnik moment,” Limp said. “From my standpoint, getting boots on the Moon and setting the groundwork for permanence on the Moon is of national importance and urgency. Rest assured, Blue will do everything in its power to try to make that happen, but in a cost-effective way.”

NASA, please don’t leave us

Since retaking office in January, Trump has mentioned human missions to Mars multiple times, but not the Moon. Isaacman, who may be confirmed as NASA administrator by the Senate as soon as next week, told lawmakers in April that the agency should pursue human missions to the Moon and Mars simultaneously. The details of how that might work haven’t been released but could come out in the White House’s detailed budget proposal for fiscal-year 2026.

A blueprint of Trump’s spending proposal released May 2 includes a 25 percent cut to NASA’s overall budget, but the plan would provide additional money for human space exploration at the Moon and Mars. “The budget funds a program to replace SLS and Orion flights to the Moon with more cost-effective commercial systems that would support more ambitious subsequent lunar missions,” the White House budget office wrote.

This part of the budget request is not controversial for industry leaders like Limp. On the other hand, the budget blueprint proposes slashing NASA’s space science budget by nearly $2.3 billion, Earth science by almost $1.2 billion, and space technology by $531 million.

While Limp didn’t directly address these budget proposals, these parts of NASA are largely focused on research projects that lack a commercial business case. Who else but a government space agency, or perhaps an especially generous type of philanthropic multi-billionaire, would pay to send a probe to study Jupiter’s icy moon Europa? Or a robot to zip by Pluto? Or how about a mission like Landsat, which documents everything from water resources to farms and urban sprawl and makes its data freely available to anyone with an Internet connection?

Most experts agree there are better ways to do these things. Reusable rockets, mass-produced satellite platforms, and improved contracting practices can bring down the costs of these missions. Bezos’ long-term goal for Blue Origin, which is to move all polluting factories off the Earth and into space, will be easier to achieve with government support, not just funding, Limp said.

“Getting up there, building factories on the Moon is a great step, and the government can really help with research dollars around that,” he said. “But it still does need the labs. The science missions need the JPLs [Jet Propulsion Laboratory] of the world. To make the human experience right, we need the Johnson Space Centers of the world to be able to kind of use that gold mine of institutional knowledge.

“I would say, and it might be a little provocative, let’s have those smart brains look on the forward-thinking types of things, the really edge of science, planning the really exotic missions, figuring out how to get to planetary bodies we haven’t gotten to before, and staying there,” Limp said.

Mark it down

For the first decade after Bezos founded Blue Origin in 2000, the company operated under the radar and seemed to move at a glacial pace. It launched its first small rocket in 2006 to an altitude of less than 300 feet and reached space with the suborbital New Shepard booster in 2015. Blue Origin finally reached orbit in January of this year on the debut test flight of its heavy-lift New Glenn rocket. Meanwhile, Blue Origin inked a deal with United Launch Alliance to supply a version of its New Glenn main engine to power that company’s Vulcan rocket.

Blue Origin’s Blue Moon MK1 lander, seen in the center, is taller than NASA’s Apollo lunar lander, currently the largest spacecraft to have landed on the Moon. Blue Moon MK2 is even larger, but all three landers are dwarfed in size by SpaceX’s Starship, NASA’s other Artemis lunar lander. Credit: Blue Origin

The next big mission for Blue Origin will be the first flight of its Blue Moon lander. The first version of Blue Moon, called MK1, will launch on a New Glenn rocket later this year and attempt to become the largest spacecraft to ever land on the Moon. This demonstration, without anyone onboard, is fully funded by Blue Origin, Limp said.

A future human-rated version, called MK2, is under development with the assistance of NASA. It will be larger and will require refueling to reach the lunar surface. Blue Moon MK1 can make a landing on one tank.

These are tangible achievements that would be the envy of any space industry startup not named SpaceX. But Musk’s rocket company left Blue Origin in the dust as it broke launch industry records repeatedly and began delivering NASA astronauts to the International Space Station in 2020. My colleague, Eric Berger, wrote a story in January describing Blue Origin’s culture. For much of its existence, one former employee said, Blue Origin had “zero incentive” to operate like SpaceX.

To ensure he would be in lock-step with his boss, Limp felt he had to ask a question that was on the minds of many industry insiders. He got the answer he wanted.

“The only question I really asked Jeff when I was talking about taking this job was, ‘What do you want Blue to be? Is it a hobby, or is it a business?'” Limp said. “And he had the right answer, which is, it’s a business, because I don’t know how to run a hobby, and I don’t think it’s sustainable.”

As preps continue, it’s looking more likely NASA will fly the Artemis II mission

NASA’s existing architecture still has a limited shelf life, and the agency will probably have multiple options for transporting astronauts to and from the Moon in the 2030s. A decision on the long-term future of SLS and Orion isn’t expected until the Trump administration’s nominee for NASA administrator, Jared Isaacman, takes office after confirmation by the Senate.

So, what is the plan for SLS?

There are different degrees of cancellation options. The most draconian would be an immediate order to stop work on Artemis II preparations. This is looking less likely than it did a few months ago and would come with its own costs. It would cost untold millions of dollars to disassemble and dispose of parts of Artemis II’s SLS rocket and Orion spacecraft. Canceling multibillion-dollar contracts with Boeing, Northrop Grumman, and Lockheed Martin would put NASA on the hook for significant termination costs.

Of course, these liabilities would be less than the $4.1 billion NASA’s inspector general estimates each of the first four Artemis missions will cost. Most of that money has already been spent for Artemis II, but if NASA spends several billion dollars on each Artemis mission, there won’t be much money left over to do other cool things.

Other options for NASA might be to set a transition point when the Artemis program would move off of the Space Launch System rocket, and perhaps even the Orion spacecraft, and switch to new vehicles.

Another possibility, which seems to be low-hanging fruit for Artemis decision-makers, could be to cancel the development of a larger Exploration Upper Stage for the SLS rocket. If there are a finite number of SLS flights on NASA’s schedule, it’s difficult to justify the projected $5.7 billion cost of developing the upgraded Block 1B version of the Space Launch System. There are commercial options available to replace the rocket’s Boeing-built Exploration Upper Stage, as my colleague Eric Berger aptly described in a feature story last year.

For now, it looks like NASA’s orange behemoth has a little life left in it. All the hardware for the Artemis II mission has arrived at the launch site in Florida.

The Trump administration will release its fiscal-year 2026 budget request in the coming weeks. Maybe then NASA will also have a permanent administrator, and the veil will lift over the White House’s plans for Artemis.

Here’s the secret to how Firefly was able to nail its first lunar landing

Firefly Aerospace’s Blue Ghost science station accomplished a lot on the Moon in the last two weeks. Among other things, its instruments drilled into the Moon’s surface, tested an extraterrestrial vacuum cleaner, and showed that future missions could use GPS navigation signals to navigate on the lunar surface.

These are all important achievements, gathering data that could shed light on the Moon’s formation and evolution, demonstrating new ways of collecting samples on other planets, and revealing the remarkable reach of the US military’s GPS satellite network.

But the pièce de résistance for Firefly’s first Moon mission might be the daily dose of imagery that streamed down from the Blue Ghost spacecraft. A suite of cameras recorded the cloud of dust created as the lander’s engine plume blew away the uppermost layer of lunar soil as it touched down March 2 in Mare Crisium, or the Sea of Crises. This location is in a flat basin situated on the upper right quadrant of the side of the Moon always facing the Earth.

Other images from Firefly’s lander showed the craft shooting tethered electrodes out onto the lunar surface, like a baseball outfielder trying to throw out a runner at home plate. Firefly’s cameras also showed the lander’s drill as it began to probe several meters into the Moon’s crust.

The first Blue Ghost mission is part of NASA’s Commercial Lunar Payload Services (CLPS) program established in 2018 to partner with US companies for cargo transportation to the Moon. Firefly is one of 13 companies eligible to compete for CLPS missions, precursors to future astronaut landings on the Moon under NASA’s Artemis program.

Now, Firefly finds itself at the top of the pack of firms seeking to gain a foothold at the Moon.

Blue Ghost landed just after sunrise at Mare Crisium, an event shown in the blow video captured with four cameras mounted on the lander to observe how its engine plume interacted with loose soil on the lunar surface. The information will be useful as NASA plans to land astronauts on the Moon in the coming years.

“Although the data is still preliminary, the 3,000-plus images we captured appear to contain exactly the type of information we were hoping for in order to better understand plume-surface interaction and learn how to accurately model the phenomenon based on the number, size, thrust and configuration of the engines,” said Rob Maddock, project manager for NASA’s SCALPSS experiment.

One of the vehicle’s payloads, named Lunar PlanetVac, dropped from the bottom of the lander and released a blast of gas to blow fine-grained lunar soil into a collection chamber for sieving. Provided by a company named Honeybee Robotics, this device could be used as a cheaper alternative to other sample collection methods, such as robotic arms, on future planetary science missions.

After two weeks of pioneering work, the Blue Ghost lander fell into darkness Sunday when the Sun sank below the horizon, robbing it of solar power and plunging temperatures below minus 200° Fahrenheit (148°Celcius). The spacecraft’s internal electronics likely won’t survive the two-week-long lunar night.

A precoded message from Blue Ghost marked the moment Sunday afternoon, signaling a transition to “monument mode.”

“Goodnight friends,” Blue Ghost radioed Firefly’s mission control center in Central Texas. “After exchanging our final bits of data, I will hold vigil in this spot in Mare Crisium to watch humanity’s continued journey to the stars. Here, I will outlast your mightiest rivers, your tallest mountains, and perhaps even your species as we know it.”

Blue Ghost’s legacy is now secure as the first fully successful commercial lunar lander. Its two-week mission was perhaps just as remarkable for what didn’t happen as it was for what did. The spacecraft encountered no significant problems on its transit to the Moon, its final descent, or during surface operations.

One of the few surprises of the mission was that the lander got hotter a little sooner than engineers predicted. At lunar noon, when the Sun is highest in the sky, temperatures can soar to 250° F (121° C).

“We started noticing that the lander was getting hotter than we expected, and we couldn’t really figure out why, because it was a little early for lunar noon,” Ray Allensworth, Firefly’s spacecraft program director, told Ars. “So we went back and started evaluating and realized that the crater that we landed next to was actually reflecting a really significant amount of heat. So we went back and we updated our thermal models, incorporated that crater into it, and it matched the environment we were seeing.”

Early Friday morning, the Blue Ghost spacecraft captured the first high-definition views of a total solar eclipse from the Moon. At the same time that skywatchers on Earth were looking up to see the Moon turn an eerie blood red, Firefly’s cameras were looking back at us as the Sun, Earth, and Moon moved into alignment and darkness fell at Mare Crisium.

The eclipse was a bonus for Firefly. It just happened to occur during the spacecraft’s two-week mission at the Moon, the timing of which was dependent on numerous factors, ranging from the readiness of the Blue Ghost lander to weather conditions at its launch site in Florida.

“We weren’t actually planning to have an eclipse until a few months prior to our launch, when we started evaluating and realizing that an eclipse was happening right before lunar sunset,” Allensworth said. “So luckily, that gave us some time to work some procedures and basically set up what we wanted to take images of, what cameras we wanted to run.”

The extra work paid off. Firefly released an image Friday showing a glint of sunlight reaching around the curvature of the Earth, some 250,000 miles (402,000 kilometers) away. This phenomenon is known as the “diamond ring” and is a subject of pursuit for many eclipse chasers, who travel to far-flung locations for a few minutes of totality.

The Blue Ghost spacecraft, named for a species of firefly, took eclipse chasing to new heights. Not only did it see the Earth block the Sun from an unexplored location on the Moon, but the lander fell into shadow for 2 hours and 16 minutes, about 18 times longer than the longest possible total solar eclipse on the Earth.

The eclipse presented challenges for Firefly’s engineers monitoring the mission from Texas. Temperatures at the spacecraft’s airless landing site plummeted as darkness took hold, creating what Allensworth called a “pseudo lunar night.”

“We were seeing those temperatures rapidly start dropping,” Allensworth said Friday. “So it was kind of an interesting game of to play with the hardware to keep everything in its temperature bounds but also still powered on and capturing data.”

Shaping up

Using navigation cameras and autonomous guidance algorithms, the spacecraft detected potential hazards at its original landing site and diverted to a safer location more than 230 feet (70 meters) away, according to Allensworth.

Finally happy with the terrain below, Blue Ghost’s computer sent the command for landing, powered by eight thrusters pulsing in rapid succession to control the craft’s descent rate. The landing was gentler than engineers anticipated, coming down at less than 2.2 mph (1 meter per second).

According to preliminary data, Blue Ghost settled in a location just outside of its 330-foot (100-meter) target landing ellipse, probably due to the last-minute divert maneuvers ordered by the vehicle’s hazard avoidance system.

“It looks like we’re slightly out of it, but it’s really OK,” Allensworth said. “NASA has told us, more than anything, that they want us to make sure we land softly… They seem comfortable where we’re at.”

Firefly originally intended to develop a spacecraft based on the design of Israel’s Beresheet lander, which was the first private mission to attempt a landing on the Moon in 2019. The spacecraft crashed, and Firefly opted to go with a new design more responsive to NASA’s requirements.

“Managing the center of gravity and the mass of the lander is most significant, and that informs a lot of how it physically takes shape,” Allensworth said. “So we did want to keep certain things in mind about that, and that really is what led to the lander being wider, shorter, broader. We have these bigger foot pads on there. All of those things were very intentional to help make the lander as stable and predictable as possible.”

These design choices must happen early in a spacecraft’s development. Landing on the Moon comes with numerous complications, including an often-uneven surface and the lack of an atmosphere, rendering parachutes useless. A lander targeting the Moon must navigate itself to a safe landing site without input from the ground.

The Odysseus, or Nova-C, lander built by Intuitive Machines snapped one of its legs and fell over on its side after arriving on the Moon last year. The altimeter on Odysseus failed, causing it to come down with too much horizontal velocity. The lander returned some scientific data from the Moon and qualified as a partial success. The spacecraft couldn’t recharge its batteries after landing on its side, and Odysseus shut down a few days after landing.

The second mission by Intuitive Machines reached the Moon on March 6, but it suffered the same fate. After tipping over, the Athena lander succumbed to low power within hours, preventing it from accomplishing its science mission for NASA.

The landers designed by Intuitive Machines are tall and skinny, towering more than 14 feet (4.3 meters) tall with a width of about 5.2 feet (1.6 meters). The Blue Ghost vehicle is short and squatty in shape—about 6.6 feet tall and 11.5 feet wide (2-by-3.5 meters). Firefly’s approach requires fewer landing legs than Intuitive Machines—four instead of six.

Steve Altemus, co-founder and CEO of Intuitive Machines, defended the design of his company’s lander in a press briefing after the second lunar landing tip-over earlier this month. The Nova-C lander isn’t too top-heavy for a safe landing because most of its cargo attaches to the bottom of the spacecraft, and for now, Altemus said Intuitive Machines is not considering a redesign.

Intuitive Machines stacked its two fuel and oxidizer tanks on top of each other, resulting in a taller vehicle. The Nova-C vehicle uses super-cold methane and liquid oxygen propellants, enabling a fast journey to the Moon over just a few days. The four propellant tanks on Blue Ghost are arranged in a diagonal configuration, with two containing hydrazine fuel and two holding an oxidizer called nitrogen tetroxide. Firefly’s Blue Ghost took about six weeks to travel from launch until landing.

The design trade-off means Firefly’s lander is heavier, with four tanks instead of two, according to Will Coogan, Blue Ghost’s chief engineer at Firefly. By going with a stockier lander design, Firefly needed to install four tanks because the spacecraft’s fuel and oxidizer have different densities. If Firefly went with just two tanks side-by-side, the spacecraft’s center of mass would change continually as it burns propellant during the final descent to the Moon, creating an unnecessary problem for the lander’s guidance, navigation, and control system to overcome.

“You want to avoid that,” Coogan told Ars before Blue Ghost’s launch. “What you can do is you can either get four tanks and have fuel and oxidizer at diagonal angles, and then you’re always centered, or you can stay with two tanks, and you can stack them.”

The four landing legs on the Blue Ghost vehicle have shock-absorbing feet, with bowl-shaped pads able to bend if the lander comes down on a rock or a slope.

“If we did come in a little bit faster, we needed the legs to be able to take that, so we tested the legs really significantly on the ground,” Allensworth said. “We basically loaded them up on a makeshift weight bench at different angles and slammed it into the ground, slammed it into concrete, slammed it into regular simulant rocks, boulders, at different angles to really characterize what the legs could do.

“It’s actually really funny, because one of the edge cases that we didn’t test is if we came down very lightly, with almost no acceleration,” she said. “And that was the case that the lander landed in. I was joking with our structural engineer that he wasted all his time.”

Proof positive

Firefly delivered 10 NASA-sponsored science and technology demonstration experiments to the lunar surface, operating under contract with NASA’s CLPS program. CLPS builds on the commercial, service-based business model of NASA’s commercial cargo and crew program for transportation to the International Space Station.

NASA officials knew this approach was risky. The last landing on the Moon by a US spacecraft was the last Apollo mission in 1972, and most of the companies involved in CLPS are less than 20 years old, with little experience in deep space missions.

A Pittsburgh company named Astrobotic failed to reach the Moon on its first attempt in January 2024. The next month, Houston-based Intuitive Machines landed its Nova-C spacecraft on the lunar surface, but it tipped over after one of its legs snapped at the moment of touchdown.

Firefly, based in Cedar Park, Texas, was the third company to try a landing. Originally established as a rocket developer, Firefly signed up to be a CLPS provider and won a $101 million contract with NASA in 2021 to transport a government-funded science package to the Moon. NASA’s instruments aboard the Blue Ghost lander cost about $44 million.

The successful landing of Firefly’s Blue Ghost earlier this month buoyed NASA’s expectations for CLPS. “Overall, it’s been a fabulous, wonderful proof positive that the CLPS model does work,” said Brad Bailey, assistant deputy associate administrator for exploration in NASA’s Science Mission Directorate.

NASA has seven more CLPS missions on contract. The next could launch as soon as August when Blue Origin plans to send its first Blue Moon lander to the Moon. NASA has booked two more Blue Ghost missions with Firefly and two more landing attempts with Intuitive Machines, plus one more flight by Astrobotic and one lander from Draper Laboratory.

Yes, we are about to be treated to a second lunar landing in a week

Because the space agency now has some expectation that Intuitive Machines will be fully successful with its second landing attempt, it has put some valuable experiments on board. Principal among them is the PRIME-1 experiment, which has an ice drill to sample any ice that lies below the surface. Drill, baby, drill.

The Athena lander also is carrying a NASA-funded “hopper” that will fire small hydrazine rockets to bounce around the Moon and explore lunar craters near the South Pole. It might even fly into a lava tube. If this happens it will be insanely cool.

Because this is a commercial program, NASA has encouraged the delivery companies to find additional, private payloads. Athena has some nifty ones, including a small rover from Lunar Outpost, a data center from Lonestar Data Holdings, and a 4G cellular network from Nokia. So there’s a lot riding on Athena‘s success.

So will it be a success?

“Of course, everybody’s wondering, are we gonna land upright?” Tim Crain, Intuitive Machines’ chief technology officer, told Ars. “So, I can tell you our laser test plan is much more comprehensive than those last time.”

During the first landing about a year ago, Odysseus‘ laser-based system for measuring altitude failed during the descent. Because Odysseus did not have access to altitude data, the spacecraft touched down faster, and on a 12-degree slope, which exceeded the 10-degree limit. As a result, the lander skidded across the surface, and one of its six legs broke, causing it to fall over.

Crain said about 10 major changes were made to the spacecraft and its software for the second mission. On top of that, about 30 smaller things, such as more efficient file management, were updated on the new vehicle.

In theory, everything should work this time. Intuitive Machines has the benefit of all of its learnings from the last time, and nearly everything worked right during this first attempt. But the acid test comes on Thursday.

The company and NASA will provide live coverage of the attempt beginning at 11: 30 am ET (16: 30 UTC) on NASA+, with landing set for just about one hour later. The Moon may be a harsh mistress, but hopefully not too harsh.

Here’s what NASA would like to see SpaceX accomplish with Starship this year

Iterate, iterate, and iterate some more

SpaceX plans to launch the seventh full-scale test flight of its massive Super Heavy booster and Starship rocket Thursday afternoon. It’s the first of what might be a dozen or more demonstration flights this year as SpaceX tries new things with the most powerful rocket ever built.

There are many things on SpaceX’s Starship to-do list in 2025. They include debuting an upgraded, larger Starship, known as Version 2 or Block 2, on the test flight preparing to launch Thursday. The one-hour launch window opens at 5 pm EST (4 pm CST; 22: 00 UTC) at SpaceX’s launch base in South Texas. You can watch SpaceX’s live webcast of the flight here.

SpaceX will again attempt to catch the rocket’s Super Heavy booster—more than 20 stories tall and wider than a jumbo jet—back at the launch pad using mechanical arms, or “chopsticks,” mounted to the launch tower. Read more about the Starship Block 2 upgrades in our story from last week.

You might think of next week’s Starship test flight as an apéritif before the entrées to come. Ars recently spoke with Lisa Watson-Morgan, the NASA engineer overseeing the agency’s contract with SpaceX to develop a modified version of Starship to land astronauts on the Moon. NASA has contracts with SpaceX worth more than $4 billion to develop and fly two Starship human landing missions under the umbrella of the agency’s Artemis program to return humans to the Moon.

We are publishing the entire interview with Watson-Morgan below, but first, let’s assess what SpaceX might accomplish with Starship this year.

There are many things to watch for on this test flight, including the deployment of 10 satellite simulators to test the ship’s payload accommodations and the performance of a beefed-up heat shield as the vehicle blazes through the atmosphere for reentry and splashdown in the Indian Ocean.

If this all works, SpaceX may try to launch a ship into low-Earth orbit on the eighth flight, expected to launch in the next couple of months. All of the Starship test flights to date have intentionally flown on suborbital trajectories, bringing the ship back toward reentry over the sea northwest of Australia after traveling halfway around the world.

Then, there’s an even bigger version of Starship called Block 3 that could begin flying before the end of the year. This version of the ship is the one that SpaceX will use to start experimenting with in-orbit refueling, according to Watson-Morgan.

In order to test refueling, two Starships will dock together in orbit, allowing one vehicle to transfer super-cold methane and liquid oxygen into the other. Nothing like this on this scale has ever been attempted before. Future Starship missions to the Moon and Mars may require 10 or more tanker missions to gas up in low-Earth orbit. All of these missions will use different versions of the same basic Starship design: a human-rated lunar lander, a propellant depot, and a refueling tanker.

Questions for 2025

Catching Starship back at its launch tower and demonstrating orbital propellant transfer are the two most significant milestones on SpaceX’s roadmap for 2025.

SpaceX officials have said they aim to fly as many as 25 Starship missions this year, allowing engineers to more rapidly iterate on the vehicle’s design. SpaceX is constructing a second launch pad at its Starbase facility near Brownsville, Texas, to help speed up the launch cadence.

Can SpaceX achieve this flight rate in 2025? Will faster Starship manufacturing and reusability help the company fly more often? Will SpaceX fly its first ship-to-ship propellant transfer demonstration this year? When will Starship begin launching large batches of new-generation Starlink Internet satellites?

Licensing delays at the Federal Aviation Administration have been a thorn in SpaceX’s side for the last couple of years. Will those go away under the incoming administration of President-elect Donald Trump, who counts SpaceX founder Elon Musk as a key adviser?

And will SpaceX gain a larger role in NASA’s Artemis lunar program? The Artemis program’s architecture is sure to be reviewed by the Trump administration and the nominee for the agency’s next administrator, billionaire businessman and astronaut Jared Isaacman.

The very expensive Space Launch System rocket, developed by NASA with Boeing and other traditional aerospace contractors, might be canceled. NASA currently envisions the SLS rocket and Orion spacecraft as the transportation system to ferry astronauts between Earth and the vicinity of the Moon, where crews would meet up with a landing vehicle provided by commercial partners SpaceX and Blue Origin.

Watson-Morgan didn’t have answers to all of these questions. Many of them are well outside of her purview as Human Landing System program manager, so Ars didn’t ask. Instead, Ars discussed technical and schedule concerns with her during the half-hour interview. Here is one part of the discussion, lightly edited for clarity.

Ars: What do you hope to see from Flight 7 of Starship?

Lisa Watson-Morgan: One of the exciting parts of working with SpaceX are these test flights. They have a really fast turnaround, where they put in different lessons learned. I think you saw many of the flight objectives that they discussed from Flight 6, which was a great success. I think they mentioned different thermal testing experiments that they put on the ship in order to understand the different heating, the different loads on certain areas of the system. All that was really good with each one of those, in addition to how they configure the tiles. Then, from that, there’ll be additional tests that they will put on Flight 7, so you kind of get this iterative improvement and learning that we’ll get to see in Flight 7. So Flight 7 is the first Version 2 of their ship set. When I say that, I mean the ship, the booster, all the systems associated with it. So, from that, it’s really more just understanding how the system, how the flaps, how all of that interacts and works as they’re coming back in. Hopefully we’ll get to see some catches, that’s always exciting.

Ars: How did the in-space Raptor engine relight go on Flight 6 (on November 19)?

Lisa Watson-Morgan: Beautifully. And that’s something that’s really important to us because when we’re sitting on the Moon… well, actually, the whole path to the Moon as we are getting ready to land on the Moon, we’ll perform a series of maneuvers, and the Raptors will have an environment that is very, very cold. To that, it’s going to be important that they’re able to relight for landing purposes. So that was a great first step towards that. In addition, after we land, clearly the Raptors will be off, and it will get very cold, and they will have to relight in a cold environment (to get off the Moon). So that’s why that step was critical for the Human Landing System and NASA’s return to the Moon.

Ars: Which version of the ship is required for the propellant transfer demonstration, and what new features are on that version to enable this test?

Lisa Watson-Morgan: We’re looking forward to the Version 3, which is what’s coming up later on, sometime in ’25, in the near term, because that’s what we need for propellant transfer and the cryo fluid work that is also important to us… There are different systems in the V3 set that will help us with cryo fluid management. Obviously, with those, we have to have the couplers and the quick-disconnects in order for the two systems to have the right guidance, navigation, trajectory, all the control systems needed to hold their station-keeping in order to dock with each other, and then perform the fluid transfer. So all the fluid lines and all that’s associated with that, those systems, which we have seen in tests and held pieces of when we’ve been working with them at their site, we’ll get to see those actually in action on orbit.

Ars: Have there been any ground tests of these systems, whether it’s fluid couplers or docking systems? Can you talk about some of the ground tests that have gone into this development?

Lisa Watson-Morgan: Oh, absolutely. We’ve been working with them on ground tests for this past year. We’ve seen the ground testing and reviewed the data. Our team works with them on what we deem necessary for the various milestones. While the milestone contains proprietary (information), we work closely with them to ensure that it’s going to meet the intent, safety-wise as well as technically, of what we’re going to need to see. So they’ve done that.

Even more exciting, they have recently shipped some of their docking systems to the Johnson Space Center for testing with the Orion Lockheed Martin docking system, and that’s for Artemis III. Clearly, that’s how we’re going to receive the crew. So those are some exciting tests that we’ve been doing this past year as well that’s not just focused on, say, the booster and the ship. There are a lot of crew systems that are being developed now. We’re in work with them on how we’re going to effectuate the crew manual control requirements that we have, so it’s been a great balance to see what the crew needs, given the size of the ship. That’s been a great set of work. We have crew office hours where the crew travels to Hawthorne [SpaceX headquarters in California] and works one-on-one with the different responsible engineers in the different technical disciplines to make sure that they understand not just little words on the paper from a requirement, but actually what this means, and then how systems can be operated.

Ars: For the docking system, Orion uses the NASA Docking System, and SpaceX brings its own design to bear on Starship?

Lisa Watson-Morgan: This is something that I think the Human Landing System has done exceptionally well. When we wrote our high-level set of requirements, we also wrote it with a bigger picture in mind—looked into the overall standards of how things are typically done, and we just said it has to be compliant with it. So it’s a docking standard compliance, and SpaceX clearly meets that. They certainly do have the Dragon heritage, of course, with the International Space Station. So, because of that, we have high confidence that they’re all going to work very well. Still, it’s important to go ahead and perform the ground testing and get as much of that out of the way as we can.

Ars: How far along is the development and design of the layout of the crew compartment at the top of Starship? Is it far along, or is it still in the conceptual phase? What can you say about that?

Lisa Watson-Morgan: It’s much further along there. We’ve had our environmental control and life support systems, whether it’s carbon dioxide monitoring fans to make sure the air is circulating properly. We’ve been in a lot of work with SpaceX on the temperature. It’s… a large area (for the crew). The seats, making sure that the crew seats and the loads on that are appropriate. For all of that work, as the analysis work has been performed, the NASA team is reviewing it. They had a mock-up, actually, of some of their life support systems even as far back as eight-plus months ago. So there’s been a lot of progress on that.

Ars: Is SpaceX planning to use a touchscreen design for crew displays and controls, like they do with the Dragon spacecraft?

Lisa Watson-Morgan: We’re in talks about that, about what would be the best approach for the crew for the dynamic environment of landing.

Ars: I can imagine it is a pretty dynamic environment with those Raptor engines firing. It’s almost like a launch in reverse.

Lisa Watson-Morgan: Right. Those are some of the topics that get discussed in the crew office hours. That’s why it’s good to have the crew interacting directly, in addition to the different discipline leads, whether it’s structural, mechanical, propulsion, to have all those folks talking guidance and having control to say, “OK, well, when the system does this, here’s the mode we expect to see. Here’s the impact on the crew. And is this condition, or is the option space that we have on the table, appropriate for the next step, with respect to the displays.”

Ars: One of the big things SpaceX needs to prove out before going to the Moon with Starship is in-orbit propellant transfer. When do you see the ship-to-ship demonstration occurring?

Lisa Watson-Morgan: I see it occurring in ’25.

Ars: Anything more specific about the schedule for that?

Lisa Watson-Morgan: That’d be a question for SpaceX because they do have a number of flights that they’re performing commercially, for their maturity. We get the benefit of that. It’s actually a great partnership. I’ll tell you, it’s really good working with them on this, but they’d have to answer that question. I do foresee it happening in ’25.

Ars: What things do you need to see SpaceX accomplish before they’re ready for the refueling demo? I’m thinking of things like the second launch tower, potentially. Do they need to demonstrate a ship catch or anything like that before going for orbital refueling?

Lisa Watson-Morgan: I would say none of that’s required. You just kind of get down to, what are the basics? What are the basics that you need? So you need to be able to launch rapidly off the same pad, even. They’ve shown they can launch and catch within a matter of minutes. So that is good confidence there. The catching is part of their reuse strategy, which is more of their commercial approach, and not a NASA requirement. NASA reaps the benefit of it by good pricing as a result of their commercial model, but it is not a requirement that we have. So they could theoretically use the same pad to perform the propellant transfer and the long-duration flight, because all it requires is two launches, really, within a specified time period to where the two systems can meet in a planned trajectory or orbit to do the propellant transfer. So they could launch the first one, and then within a week or two or three, depending on what the concept of operations was that we thought we could achieve at that time, and then have the propellant transfer demo occur that way. So you don’t necessarily need two pads, but you do need more thermal characterization of the ship. I would say that is one of the areas (we need to see data on), and that is one of the reasons, I think, why they’re working so diligently on that.

Ars: You mentioned the long-duration flight demonstration. What does that entail?

Lisa Watson-Morgan: The simple objectives are to launch two different tankers or Starships. The Starship will eventually be a crewed system. Clearly, the ones that we’re talking about for the propellant transfer are not. It’s just to have the booster and Starship system launch, and within a few weeks, have another one launch, and have them rendezvous. They need to be able to find each other with their sensors. They need to be able to come close, very, very close, and they need to be able to dock together, connect, do the quick connect, and make sure they are able, then, to flow propellant and LOX (liquid oxygen) to another system. Then, we need to be able to measure the quantity of how much has gone over. And from that, then they need to safely undock and dispose.

Ars: So the long-duration flight demonstration is just part of what SpaceX needs to do in order to be ready for the propellant transfer demonstration?

Lisa Watson-Morgan: We call it long duration just because it’s not a 45-minute or an hour flight. Long duration, obviously, that’s a relative statement, but it’s a system that can stay up long enough to be able to find another Starship and perform those maneuvers and flow of fuel and LOX.

Ars: How much propellant will you transfer with this demonstration, and do you think you’ll get all the data you need in one demonstration, or will SpaceX need to try this several times?

Lisa Watson-Morgan: That’s something you can ask SpaceX (about how much propellant will be transferred). Clearly, I know, but there’s some sensitivity there. You’ve seen our requirements in our initial solicitation. We have thresholds and goals, meaning we want you to at least do this, but more is better, and that’s typically how we work almost everything. Working with commercial industry in these fixed-price contracts has worked exceptionally well, because when you have providers that are also wanting to explore commercially or trying to make a commercial system, they are interested in pushing more than what we would typically ask for, and so often we get that for an incredibly fair price.

Two lunar landers are on the way to the Moon after SpaceX’s double moonshot

clps, Commercial space, falcon 9, Firefly Aerospace, ispace, Japan, launch, moon, NASA, Science, Space / /

Julianna Scheiman, director of NASA science missions for SpaceX, said it made sense to pair the Firefly and ispace missions on the same Falcon 9 rocket.

“When we have two missions that can each go to the Moon on the same launch, that is something that we obviously want to take advantage of,” Scheiman said. “So when we found a solution for the Firefly and ispace missions to fly together on the same Falcon 9, it was a no-brainer to put them together.”

SpaceX stacked the two landers, one on top of the other, inside the Falcon 9’s payload fairing. Firefly’s lander, the larger of the two spacecraft, rode on top of the stack and deployed from the rocket first. The Resilience lander from ispace launched in the lower position, cocooned inside a specially designed canister. Once Firefly’s lander separated from the Falcon 9, the rocket jettisoned the canister, performed a brief engine firing to maneuver into a slightly different orbit, then released ispace’s lander.

This dual launch arrangement resulted in a lower launch price for Firefly and ispace, according to Scheiman.

“At SpaceX, we are really interested in and invested in lowering the cost of launch for everybody,” she said. “So that’s something we’re really proud of.”

The Blue Ghost and Resilience landers will take different paths toward the Moon.

Firefly’s Blue Ghost will spend about 25 days in Earth orbit, then four days in transit to the Moon. After Blue Ghost enters lunar orbit, Firefly’s ground team will verify the readiness of the lander’s propulsion and navigation systems and execute several thruster burns to set up for landing.

Blue Ghost’s final descent to the Moon is tentatively scheduled for March 2. The target landing site is in Mare Crisium, an ancient 350-mile-wide (560-kilometer) impact basin in the northeast part of the near side of the Moon.

After touchdown, Blue Ghost will operate for about 14 days (one entire lunar day). The instruments aboard Firefly’s lander include a subsurface drill, an X-ray imager, and an experimental electrodynamic dust shield to test methods of repelling troublesome lunar dust from accumulating on sensitive spacecraft components.

The Resilience lander from ispace will take four to five months to reach the Moon. It carries several intriguing tech demo experiments, including a water electrolyzer provided by a Japanese company named Takasago Thermal Engineering. This demonstration will test equipment that future lunar missions could use to convert the Moon’s water ice resources into electricity and rocket fuel.

The lander will also deploy a “micro-rover” named Tenacious, developed by an ispace subsidiary in Luxembourg. The Tenacious rover will attempt to scoop up lunar soil and capture high-definition imagery of the Moon.

Ron Garan, CEO of ispace’s US-based subsidiary, told Ars that this mission is “pivotal” for the company.

“We were not fully successful on our first mission,” Garan said in an interview. “It was an amazing accomplishment, even though we didn’t have a soft landing… Although the hardware worked flawlessly, exactly as it was supposed to, we did have some lessons learned in the software department. The fixes to prevent what happened on the first mission from happening on the second mission were fairly straightforward, so that boosts our confidence.”

The ispace subsidiary led by Garan, a former NASA astronaut, is based in Colorado. While the Resilience lander launched Wednesday is not part of the CLPS program, the company will build an upgraded lander for a future CLPS mission for NASA, led by Draper Laboratory.

“I think the fact that we have two lunar landers on the same rocket for the first time in history is pretty substantial,” Garan said. I think we all are rooting for each other.”

Investors need to see more successes with commercial lunar landers to fully realize the market’s potential, Garan said.

“That market, right now, is very nascent. It’s very, very immature. And one of the reasons for that is that it’s very difficult for companies that are contemplating making investments on equipment, experiments, etc., to put on the lunar surface and lunar orbit,” Garan said. “It’s very difficult to make those investments, especially if they’re long-term investments, because there really hasn’t been a proof of concept yet.”

“So every time we have a success, that makes it more likely that these companies that will serve as the foundation of a commercial lunar market movement will be able to make those investments,” Garan said. “Conversely, every time we have a failure, the opposite happens.”

There was a straight shot from Earth to the Moon and Mars last night

The most recent lunar occultation of Mars that was visible from the United States occurred on December 7, 2022. A handful of these events occur every few years around each Martian opposition, but they are usually only visible from a small portion of Earth, often over the ocean or in polar regions. The next lunar occultation of Mars visible across most of the United States will happen on the night of February 4–5, 2042. There are similar occultations of Mars in 2035, 2038, and 2039 visible in narrow swaths of South Florida and the Pacific Northwest.

This photo was taken with a handheld Canon 80D and a 600 mm lens. Settings were 1/2000 sec, f/8, ISO 400. The image was cropped and lightly edited in Adobe Lightroom.

The Moon also periodically covers Venus, Jupiter, Saturn, and the Solar System’s more distant planets. A good resource on lunar occultations is In-The-Sky.org, which lists events where the Moon will block out a planet or a bright star. Be sure you choose your location on the upper right corner of the page and toggle year by year to plan out future viewing opportunities.

Viewing these kinds of events can be breathtaking and humbling. In 2012, I was lucky enough to observe the transit of Venus in front of the Sun, something that only happens twice every 121 years.

Seeing Mars, twice the size of the Moon, rising above the lunar horizon like a rusty BB pellet next to a dusty volleyball provided a perfect illustration of the scale and grandeur of the Solar System. Similarly, viewing Venus dwarfed by the Sun was a revealing moment. The worlds accompanying Earth around the Sun are varied in size, shape, color, and composition.

In one glance, an observer can see the barren, airless lunar surface and a cold, desert planet that once harbored rivers, lakes, and potentially life, all while standing on our own planet, an oasis in the cosmos. One thing that connects them all is humanity’s quest for exploration. Today, robots are operating on or around the Moon and Mars. Governments and private companies are preparing to return astronauts to the lunar surface within a few years, then moving on to dispatch human expeditions to the red planet.

Plans to land astronauts on the Moon are already in motion, but significant financial and technological hurdles remain for a crew mission to put humans on Mars. But for a short time Monday night, it looked like there was a direct path.
