What would a “simplified” Starship plan for the Moon actually look like?


The problem is that it may be difficult to find options that both NASA and SpaceX like.

In what will likely be his most consequential act as NASA’s interim leader, Sean Duffy said last month that the space agency was “opening up” its competition to develop a lunar lander that will put humans on the surface of the Moon.

As part of this move, Duffy asked NASA’s current lunar lander contractors, SpaceX and Blue Origin, for more nimble plans. Neither has specified those plans publicly, but a recent update from SpaceX referenced a “simplified” version of the Starship system it’s building to help NASA return humans to the Moon.

“Since the contract was awarded, we have been consistently responsive to NASA as requirements for Artemis III have changed and have shared ideas on how to simplify the mission to align with national priorities,” the company said. “In response to the latest calls, we’ve shared and are formally assessing a simplified mission architecture and concept of operations that we believe will result in a faster return to the Moon while simultaneously improving crew safety.”

So what would a simplified architecture look like? It is difficult to say for sure, but there are some interesting ideas floating around.

First, let’s make a couple of assumptions. Any approach to shortening the Artemis III timeline should not involve major hardware changes. This rules out a “stubby” version of Starship, which would require a significant reworking of the vehicle’s internals. Essentially, any new plan should use hardware that exists largely in the structural shape and form it’s in. And for SpaceX, we’ll assume that “simplified” means not working directly with other contractors beyond those already involved in Artemis III.

With these ground rules, there are two changes that SpaceX, in conjunction with NASA, could make to simplify or potentially accelerate Artemis: “Expendable Starships” and “Enter the Dragon.”

Expendable Starships

One of the biggest challenges with the existing plan is refueling in low-Earth orbit. Essentially, SpaceX must launch a “depot” variant of Starship and then fuel it with “tanker” Starship upper stages. Once this depot is full, the “lunar lander” variant of Starship launches, is refueled, and then flies to the Moon. There, it awaits a crew of astronauts on board Orion to land them on the Moon and return them to lunar orbit.

Estimates vary widely for how many ‘”tanker” Starships will be required to fuel the depot for a lunar mission. In truth, no one will know the answer until there is a mature Starship design with real-world performance numbers and demonstrated efficiency of propellant transfer and storage.

Critics of the SpaceX plan, and there are many, say the mission architecture is clunky and untenable. One household name in the space industry recently told Ars he believes it would take up to 20 to 40 “tanker” launches to fill a depot. That seems high, but a number in the ballpark of 12 to 20 flights (probably with the next-generation V4 ships) is realistic.

That is a lot of launches, to be sure. But it’s not inconceivable that a company now regularly launching three Falcon 9 rockets a week could launch a dozen or more Starships per month in the not-too-distant future.

There is one relatively straightforward way to cut down on the number of “tanker” launches. For early Artemis missions, SpaceX could use expendable “tanker” Starships rather than landing and reusing them. It is not clear how much this would boost the capacity of Starship, but it likely would be considerable. SpaceX probably could remove the grid fins (multiple tons), as well as a tiled heat shield that (according to rumors, it must be said) is running considerably more massive than what was budgeted for. There also would be propellant mass savings without the need for reentry and landing burns.

Using an optimized, expendable Starship might reduce the number of tanker missions required by up to 50 percent. There are downsides, including a significant increase in costs and an undermining of the whole point of Starship: full and rapid reuse.

It is safe to say that Starship will be the largest human spacecraft to land on the Moon by far.

There is a third downside, and this is perhaps the most important one. An “expendable” Starship plan would be anathema to the leadership of SpaceX, including founder Elon Musk. Officials there do not believe the space industry has fully digested how Starship will transform the launch industry.

“You don’t yet understand how many Starship launches will happen,” a senior SpaceX source told Ars.

The company is aiming to launch 1 million tons of payload to orbit per year, the majority of which will be propellant. SpaceX simply believes that once it locks in on Starship operations, launching a dozen or many more rockets per month won’t be a big deal. So why waste time on expendable rockets? That era is over.

Enter the Dragon

A second option would be to rely solely on SpaceX hardware.

I don’t expect NASA to be interested in this idea, but it’s worth discussing. Nearly a year ago, in the immediate aftermath of the presidential election, Republican space officials were considering canceling Artemis and substituting a “competition” similar to the Commercial Cargo program. It was thought that both SpaceX and Blue Origin would bid plans to land humans on the Moon and that NASA would fund both.

These plans have largely fallen by the wayside in the last 12 months, though. NASA (and perhaps most importantly, paymasters in Congress) prefer to stick with the Space Launch System rocket and Orion spacecraft for the initial Artemis missions.

But if pressed, SpaceX could come up with a simplified Moon landing architecture that requires fewer refuelings. There are multiple ways this could be done, so I’ll offer just one variant here:

  • SpaceX launches the “lunar” variant of Starship into low-Earth orbit, uncrewed
  • SpaceX launches two “depot” variants of Starship into orbit
  • Both depots are fueled (perhaps requiring 3-5 “tanker” launches each)
  • One of these depots flies out to low-lunar orbit, the other fuels the Lunar starship previously launched into low-Earth orbit
  • A crew of four astronauts launches on Crew Dragon, which docks with the Lunar Starship
  • Crew transfers to Starship, which undocks from Dragon, flies to the Moon, and lands
  • After days on the surface, this Starship launches from the Moon and refuels from the second depot in lunar orbit
  • Starship flies back to low-Earth orbit, docks with Dragon, and Dragon returns to Earth

Does that sound complicated? Sure. But it’s arguably not as complicated as an Orion-based mission, and it would likely necessitate fewer refuelings. This is because Starship does not need to rendezvous with Orion in a near-rectilinear halo orbit, and there is no 100-day loiter requirement for a fully fueled Starship at the Moon.

This solution, however, would likely be viewed as toxic by NASA’s safety community due to the need to refuel in lunar orbit with crew on board. A decade ago, when SpaceX proposed fueling the Falcon 9 vehicle on the ground with astronauts on board—a procedure known as load-and-go—engineers tasked with the crew’s safety went berserk.

“When SpaceX came to us and said we want to load the crew first, and then the propellant, mushroom clouds went off in our safety community,” Phil McAlister, NASA’s then-chief of commercial spaceflight, told me when I was writing the book Reentry. “I mean, hair-on-fire stuff. It was just conventional wisdom that you load the propellant first and get it thermally stable. Fueling is a very dynamic operation. The vehicle is popping and hissing. The safety community was adamantly against this.”

It’s probably safe to say that SpaceX would be unhappy with the first solution offered here, and NASA would be unhappy with the second one. For these reasons, SpaceX’s current architecture may well remain the default one for Artemis III.

Intuitive Machines—known for its Moon landers—will become a military contractor

The company’s success in just reaching the Moon’s surface has put it in position to become one of NASA’s leading lunar contractors. NASA has awarded more robotic lunar lander contracts to Intuitive Machines than to any other company, with two missions complete and at least two more in development. Intuitive Machines is also one of the companies NASA selected to compete for a contract to develop an unpressurized Moon buggy for astronauts to drive across the lunar surface.

Branching out

The addition of Lanteris will make Intuitive Machines competitive for work outside of the lunar realm.

“This marks the moment Intuitive Machines transitions from a lunar company to a multi-domain space prime, setting the pace for how the industry’s next generation will operate,” said Steve Altemus, the company’s CEO.

Altemus said Lanteris will initially become a subsidiary of Intuitive Machines, followed by a complete integration under the Intuitive Machines banner.

Lanteris builds numerous satellites for the US Space Force, NASA, and commercial customers. The company can trace its history to 1957, when it was established as the Western Development Laboratories division of Philco Corporation, a battery and electronics manufacturer founded in 1892.

Philco constructed a satellite factory in Palo Alto, California, and produced its first spacecraft for launch in 1960. The satellite, named Courier 1B, made history as the world’s first active repeater communications relay station in orbit, meaning it could receive messages from the ground, store them, and then retransmit them.

The contractor underwent numerous mergers and acquisitions, becoming part of Ford Motor Company, Loral Corporation, and the Canadian company MDA Space before it was bought up by Advent more than two years ago. In nearly 70 years, the company has produced more than 300 satellites, many of them multi-ton platforms for broadcasting television signals from geosynchronous orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator. Lanteris has contracts to build dozens more satellites in the next few years.

Blue Origin will ‘move heaven and Earth’ to help NASA reach the Moon faster, CEO says

Blue Origin stands ready to help NASA achieve its goals with regard to landing humans on the Moon as soon as possible, the company’s chief executive said Saturday in an interview with Ars.

“We just want to help the US get to the Moon,” said Dave Limp, CEO of the space company founded by Jeff Bezos. “If NASA wants to go quicker, we would move heaven and Earth, pun intended, to try to get to the Moon sooner. And I think we have some good ideas.”

Limp spoke on Saturday, about 24 hours ahead of the company’s second launch of the large New Glenn rocket. Carrying the ESCAPADE spacecraft for NASA, the mission has a launch window that opens at 2: 45 pm ET (19: 45 UTC) at Cape Canaveral Space Force Station in Florida, and runs for a little more than two hours.

NASA seeks a faster return

This year it has become increasingly apparent that, should NASA stick to its present plans for the Artemis III lunar landing mission, China is on course to beat the United States back to the Moon with humans. In recognition of this, about three weeks ago, NASA acting administrator Sean Duffy said the space agency was reopening the competition for a human lander.

SpaceX and Blue Origin both have existing contracts for human landers, but the government has asked each providers for an option to accelerate their timeline. NASA currently has a target landing date of 2027, but that is unrealistic using the present approach of SpaceX’s Starship or Blue Origin’s large Mk. 2 lander.

Ars exclusively reported in early October that Blue Origin had begun work on a faster architecture, involving multiple versions of its Mk. 1 cargo lander as well as a modified version of this vehicle tentatively called Mk 1.5. Limp said that after Duffy asked for revised proposals, Blue Origin responded almost immediately.

“We’ve sent our initial summary of that over, and we have a full report of that due here shortly,” he said. “I’m not going to go into the details because I think that’s probably for NASA to talk about, not us, but we have some ideas that we think could accelerate the path to the Moon. And I hope NASA takes a close look.”

SpaceX teases simplified Starship as alarms sound over Moon landing delays


“SpaceX shares the goal of returning to the Moon as expeditiously as possible.”

SpaceX on Thursday released the most detailed public update in nearly two years on its multibillion-dollar contract to land astronauts on the Moon for NASA, amid growing sentiment that China is likely to beat the United States back to the lunar surface with humans.

In a lengthy statement published on SpaceX’s website Thursday, the company said it “will be a central enabler that will fulfill the vision of NASA’s Artemis program, which seeks to establish a lasting presence on the lunar surface… and ultimately forge the path to land the first humans on Mars.”

Getting to Mars is SpaceX’s overarching objective, a concise but lofty mission statement introduced by Elon Musk at the company’s founding nearly a quarter-century ago. Musk has criticized NASA’s Artemis program, which aims to return US astronauts to the Moon for the first time since the last Apollo lunar mission in 1972, as unambitious and too reliant on traditional aerospace contractors.

Is this a priority for SpaceX?

The Starship rocket and its massive Super Heavy booster are supposed to be SpaceX’s solution for fulfilling Musk’s mission of creating a settlement on Mars. The red planet has been the focus each time Musk has spoken at length about Starship in the last couple of years, with Moon missions receiving little or no time in his comments, whether they’re scripted or off the cuff.

In the background, SpaceX’s engineers have been busy developing a version of the Starship rocket to fly crews to and from the surface of the Moon for NASA. The agency’s current architecture calls for astronauts to transit from the Earth to the vicinity of the Moon inside NASA’s Orion spacecraft, made by Lockheed Martin, then link up with Starship in lunar orbit for a ride to the Moon’s south pole.

After completing their mission on the surface, the astronauts will ride Starship back into space and dock with Orion to bring them home. Starship and Orion may also link together by docking at the planned Gateway mini-space station orbiting the Moon, but Gateway’s future is in question as NASA faces budget cuts.

NASA has contracts with SpaceX valued at more than $4 billion to land two astronaut crews on the Moon on NASA’s Artemis III and Artemis IV missions. The contract also covers milestones ahead of any human mission, such as an uncrewed Starship landing and takeoff at the Moon, to prove the vehicle is ready.

The fresh update from SpaceX lists recent achievements the company has accomplished on the path to the Moon, including demos of life support and thermal control systems, the docking adapter to link Starship with Orion, navigation hardware and software, a landing leg structural test, and engine firings in conditions similar to what the ship will see at the Moon.

Many of these milestones were completed ahead of schedule, SpaceX said. But the biggest tests, such as demonstrating in-orbit refueling, remain ahead. Some NASA officials believe mastering orbital refueling will take many tries, akin to SpaceX’s iterative two steps forward, one step back experience with its initial Starship test flights.

The first test to transfer large amounts of cryogenic liquid methane and liquid oxygen between two Starships in low-Earth orbit is now planned for next year. This time a year ago, SpaceX aimed to launch the first orbital refueling demo before the end of 2025.

Orbital refueling is key to flying Starship to the Moon or Mars. The rocket consumes all of its propellant getting to low-Earth orbit, and it needs more gas to go farther. For lunar missions, SpaceX will launch a Starship-derived propellant depot into orbit, refill it with perhaps a dozen or more Starship tankers, and then dock the Starship lander with it to load its tanks before heading off to the Moon.

Officials haven’t given a precise number of tanker flights required for a Starship lunar lander. It’s likely engineers won’t settle on an exact number until they obtain data on how much of the super-cold liquid propellant boils off in space, and how efficient it is to transfer from ship to ship. Whatever the number, SpaceX says Starship’s design for recovery and rapid reuse will facilitate a fast-paced launch and refueling campaign.

The upshot of overcoming the refueling hurdle is Starship’s promise of becoming a transformative vehicle. Starship is enormous compared to any other concept for landing on the Moon. One single Starship has a pressurized habitable volume of more than 600 cubic meters, or more than 21,000 cubic feet, roughly two-thirds that of the entire International Space Station, according to SpaceX. Starship will have dual airlocks, or pathways for astronauts and equipment to exit and enter the spacecraft.

An elevator will lower people and cargo down to the lunar surface from the crew cabin at the top of the 15-story-tall spacecraft. For pure cargo missions, SpaceX says Starship will be capable of landing up to 100 metric tons of cargo directly on the Moon’s surface. This would unlock the ability to deliver large rovers, nuclear reactors, or lunar habitats to the Moon in one go. In the long run, the Starship architecture could allow landers to be reused over and over again. All of this is vital if NASA wants to build a permanent base or research outpost on the Moon.

A competition in more ways than one

But hard things take time. SpaceX dealt with repeated setbacks in the first half of this year: three in-flight failures of Starship and one Starship explosion on the ground at the company’s development facility in South Texas. Since then, teams have reeled off consecutive successful Starship test flights ahead of the debut of an upgraded Starship variant called Version 3 in the coming months. Starship Version 3 will have the accoutrements for refueling, and SpaceX says this will also be the version to fly to the Moon.

The recent Starship delays, coupled with the scope of work to go, have raised concerns that the Artemis program is falling behind China’s initiative to land its own astronauts on the Moon. China’s goal is to do it by 2030, a schedule reiterated in Chinese state media this week. The Chinese program relies on an architecture more closely resembling NASA’s old Apollo designs.

The official schedule for the first Artemis crew landing, on Artemis III, puts it in 2027, but that timeline is no longer achievable. Starship and new lunar spacesuits developed by Axiom Space won’t be ready, in part because NASA didn’t award the contracts to SpaceX and Axiom until 2021 and 2022.

All of this adds up to waning odds that the United States can beat China back to the Moon, according to a growing chorus of voices in the space community. Last month, former NASA chief Jim Bridenstine, who led the agency during the first Trump administration, told Congress the United States was likely to lose the second lunar space race.

At a space conference earlier this week, Bridenstine suggested the Trump administration use its powers to fast-track a lunar landing, even floating the idea of invoking the Defense Production Act, a law that grants the president authority to marshal industrial might to meet pressing national needs.

An executive order from President Donald Trump could authorize such an effort and declare a “national security imperative that we’re going to beat China to the Moon,” Bridenstine said at the American Astronautical Society’s von Braun Space Exploration Symposium in Huntsville, Alabama.

Charlie Bolden, NASA’s administrator under former President Barack Obama, also expressed doubts that NASA could land humans on the Moon before China, or by the end of Trump’s term in the White House. “Let’s be real, OK? Everybody in this room knows, to say we’re going to do it by the end of the term, or we’re going to do it before the Chinese, that doesn’t help industry.”

But Bolden said maybe it’s not so terrible if China lands people on the Moon before NASA can return with astronauts. “We may not make 2030, and that’s OK with me, as long as we get there in 2031 better than they are with what they have there.”

Sean Duffy, NASA’s acting administrator, doesn’t see it the same way. Duffy said last week he would give contractors until this Wednesday to propose other ways of landing astronauts on the Moon sooner than the existing plan. SpaceX and Blue Origin, the space company founded by billionaire Jeff Bezos, confirmed they submitted updated plans to NASA this week.

Blue Origin has a separate contract with NASA to provide its own human-rated lunar lander—Blue Moon Mark 2—for entry into service on the Artemis V mission, likely not to occur before the early 2030s. A smaller unpiloted lander—Blue Moon Mark 1—is on track to launch on Blue Origin’s first lunar landing attempt next year.

Blue Moon Mark 1 is still a big vehicle, standing taller than the lunar lander used by NASA during the Apollo program. But it doesn’t match the 52-foot (16-meter) height of Blue Origin’s Mark 2 lander, and tops out well short of the roughly 165-foot-tall (50-meter) Starship lander.

What’s more, Blue Moon Mark 1 won’t need to be refueled after launch, unlike Starship and Mark 2. Jacki Cortese, senior director of civil space at Blue Origin, confirmed Tuesday that her company is looking at employing a “more incremental approach” using Mark 1 to accelerate an Artemis crew landing. Ars first reported Blue Origin was studying how to modify Blue Moon Mark 1 for astronauts.

All of this is a reminder of something Blue Origin said in 2021, when NASA passed over Bezos’ company to award the first Artemis lander contract to SpaceX. Blue Origin protested the award and filed a lawsuit against the government, triggering a lunar lander work stoppage that lasted several months until a federal judge dismissed the suit.

Blue Origin said SpaceX’s approach with numerous refueling sorties was “immensely complex and high risk” and argued its proposal was the better option for NASA. The statement has taken on a meme-worthy status among fans of Starship.

But SpaceX bid a lower cost, and NASA officials said it was the only proposal the agency could afford at the time. And then, when Blue Origin won a contract from NASA in 2023 to provide a second lander option, the company’s concept also hinged on refueling the Blue Moon Mark 2 lander in space.

Now, SpaceX is making a new offering to NASA. Like Blue Origin, SpaceX said it has sent in a proposal for a “simplified architecture” for landing astronauts on the Moon, but did not provide details.

“We’ve shared and are formally assessing a simplified mission architecture and concept of operations that we believe will result in a faster return to the Moon while simultaneously improving crew safety,” the company said.

Since NASA selected SpaceX for the Human Landing System contract in 2021, the company said it has been “consistently responsive to NASA as requirements for Artemis III have changed.”

For example, NASA originally required SpaceX to only demonstrate it could land Starship on the Moon before moving forward with a crew mission. Lori Glaze, who leads NASA’s human exploration division, said in July that the agency is now requiring the uncrewed landing demo to also include an ascent from the Moon’s surface. NASA wants to know if Starship can not just land astronauts on the Moon, but also get them back.

“Starship continues to simultaneously be the fastest path to returning humans to the surface of the Moon and a core enabler of the Artemis program’s goal to establish a permanent, sustainable presence on the lunar surface,” SpaceX said. “SpaceX shares the goal of returning to the Moon as expeditiously as possible, approaching the mission with the same alacrity and commitment that returned human spaceflight capability to America under NASA’s Commercial Crew program.”

SpaceX has built a reputation for doing things quickly. One example has been the rapid-fire launch cadence of the company’s workhorse Falcon 9 rocket. SpaceX is setting up launch pads and factories to manufacture and launch Super Heavy and Starshipcombining together to make the largest rocket ever built—at an even faster rate than Falcon 9.

The company has launched 11 full-scale test flights of Starship/Super Heavy since April 2023. “This campaign has quickly matured the core Starship and has produced numerous feats,” SpaceX said. The company listed some of them:

  • Multiple successful ascents of the world’s most powerful rocket
  • The launch, return, catch, and reuse of that rocket to unlock the high launch rate cadence needed for lunar missions
  • The transfer of approximately 5 metric tons of cryogenic propellant between tanks while in space
  • Successful in-space relights of the Raptor engines that are critical for the maneuvers that will send Starship to the Moon
  • Multiple controlled reentries through Earth’s atmosphere

It’s true that these feats have come fast. Many more remain on the road ahead before SpaceX can make good on its commitment to NASA.

NASA races to keep Artemis II on schedule, even when workers aren’t being paid

“The Office of Procurement has sent letters to contractors doing excepted work (including all the Artemis II contractors) indicating that work is authorized during the lapse in funding,” the official said. “Most workers have indicated a willingness to continue the work in the event of contract funding running out prior to the government reopening.”

Working on borrowed time

Several months of work remain ahead for the Artemis II team to finish testing the SLS rocket and Orion spacecraft, complete training of the astronauts and flight control teams, and then transfer the entire 322-foot-tall (98-meter) launch vehicle out to Launch Complex 39B for a fueling demonstration and launch countdown.

Thousands of workers across the country, primarily in Florida, Texas, and Alabama, are still reporting for duty to keep Artemis II’s launch date early next year. In many cases, they’re not getting their paychecks.

Even while work continues, the government shutdown is creating inefficiencies that, if left unchecked, will inevitably impact the Artemis II schedule. Just look at what’s happening with air traffic controllers across the United States as many of them are forced to take second jobs due to missed paychecks. The funding stalemate has contributed to widespread air traffic controller shortages and flight delays.

Kirk Shireman, vice president and program manager for Orion at Lockheed Martin, said Tuesday that the shutdown initially created a “nuisance” for teams working on the Artemis II mission. But it won’t be just a nuisance forever.

“I do think we’re rapidly approaching the point where it will be a significant impact, and it’s more to do with overall infrastructure,” Shireman said in response to a question from Ars at the von Braun Space Exploration Symposium in Huntsville, Alabama.

“Some of you flew here,” he said. “I suspect if you weren’t delayed coming here, you’re probably going to be delayed going home, even in the airport going through TSA. Everything that affects people’s lives is affected by the government, and when it’s shut down, it’s going to have its toll, and it’s probably going to be these secondary impacts that ultimately do it.”

NASA’s next Moonship reaches last stop before launch pad

The Orion spacecraft, which will fly four people around the Moon, arrived inside the cavernous Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida late Thursday night, ready to be stacked on top of its rocket for launch early next year.

The late-night transfer covered about 6 miles (10 kilometers) from one facility to another at the Florida spaceport. NASA and its contractors are continuing preparations for the Artemis II mission after the White House approved the program as an exception to work through the ongoing government shutdown, which began on October 1.

The sustained work could set up Artemis II for a launch opportunity as soon as February 5 of next year. Astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen will be the first humans to fly on the Orion spacecraft, a vehicle that has been in development for nearly two decades. The Artemis II crew will make history on their 10-day flight by becoming the first people to travel to the vicinity of the Moon since 1972.

Where things stand

The Orion spacecraft, developed by Lockheed Martin, has made several stops at Kennedy over the last few months since leaving its factory in May.

First, the capsule moved to a fueling facility, where technicians filled it with hydrazine and nitrogen tetroxide propellants, which will feed Orion’s main engine and maneuvering thrusters on the flight to the Moon and back. In the same facility, teams loaded high-pressure helium and ammonia coolant into Orion propulsion and thermal control systems.

The next stop was a nearby building where the Launch Abort System was installed on the Orion spacecraft. The tower-like abort system would pull the capsule away from its rocket in the event of a launch failure. Orion stands roughly 67 feet (20 meters) tall with its service module, crew module, and abort tower integrated together.

Teams at Kennedy also installed four ogive panels to serve as an aerodynamic shield over the Orion crew capsule during the first few minutes of launch.

It was then time to move Orion to the Vehicle Assembly Building (VAB), where a separate team has worked all year to stack the elements of NASA’s Space Launch System rocket. In the coming days, cranes will lift the spacecraft, weighing 78,000 pounds (35 metric tons), dozens of stories above the VAB’s center aisle, then up and over the transom into the building’s northeast high bay to be lowered atop the SLS heavy-lift rocket.

Blue Origin aims to land next New Glenn booster, then reuse it for Moon mission


“We fully intend to recover the New Glenn first stage on this next launch.”

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.

How America fell behind China in the lunar space race—and how it can catch back up


Thanks to some recent reporting, we’ve found a potential solution to the Artemis blues.

For the last month, NASA’s interim administrator, Sean Duffy, has been giving interviews and speeches around the world, offering a singular message: “We are going to beat the Chinese to the Moon.”

This is certainly what the president who appointed Duffy to the NASA post wants to hear. Unfortunately, there is a very good chance that Duffy’s sentiment is false. Privately, many people within the space industry, and even at NASA, acknowledge that the US space agency appears to be holding a losing hand. Recently, some influential voices, such as former NASA Administrator Jim Bridenstine, have spoken out.

“Unless something changes, it is highly unlikely the United States will beat China’s projected timeline to the Moon’s surface,” Bridenstine said in early September.

As the debate about NASA potentially losing the “second” space race to China heats up in Washington, DC, everyone is pointing fingers. But no one is really offering answers for how to beat China’s ambitions to land taikonauts on the Moon as early as the year 2029. So I will. The purpose of this article is to articulate how NASA ended up falling behind China, and more importantly, how the Western world could realistically retake the lead.

But first, space policymakers must learn from their mistakes.

Begin at the beginning

Thousands of words could be written about the space policy created in the United States over the last two decades and all of the missteps. However, this article will only hit the highlights (lowlights). And the story begins in 2003, when two watershed events occurred.

The first of these was the loss of space shuttle Columbia in February, the second fatal shuttle accident, which signaled that the shuttle era was nearing its end, and it began a period of soul-searching at NASA and in Washington, DC, about what the space agency should do next.

“There’s a crucial year after the Columbia accident,” said eminent NASA historian John Logsdon. “President George W. Bush said we should go back to the Moon. And the result of the assessment after Columbia is NASA should get back to doing great things.” For NASA, this meant creating a new deep space exploration program for astronauts, be it the Moon, Mars, or both.

The other key milestone in 2003 came in October, when Yang Liwei flew into space and China became the third country capable of human spaceflight. After his 21-hour spaceflight, Chinese leaders began to more deeply appreciate the soft power that came with spaceflight and started to commit more resources to related programs. Long-term, the Asian nation sought to catch up to the United States in terms of spaceflight capabilities and eventually surpass the superpower.

It was not much of a competition then. China would not take its first tentative steps into deep space for another four years, with the Chang’e 1 lunar orbiter. NASA had already walked on the Moon and sent spacecraft across the Solar System and even beyond.

So how did the United States squander such a massive lead?

Mistakes were made

SpaceX and its complex Starship lander are getting the lion’s share of the blame today for delays to NASA’s Artemis Program. But the company and its lunar lander version of Starship are just the final steps on a long, winding path that got the United States where it is today.

After Columbia, the Bush White House, with its NASA Administrator Mike Griffin, looked at a variety of options (see, for example, the Exploration Systems Architecture Study in 2005). But Griffin had a clear plan in his mind that he dubbed “Apollo on Steroids,” and he sought to develop a large rocket (Ares V), spacecraft (later to be named Orion), and a lunar lander to accomplish a lunar landing by 2020. Collectively, this became known as the Constellation Program.

It was a mess. Congress did not provide NASA the funding it needed, and the rocket and spacecraft programs quickly ran behind schedule. At one point, to pay for surging Constellation costs, NASA absurdly mulled canceling the just-completed International Space Station. By the end of the first decade of the 2000s, two things were clear: NASA was going nowhere fast, and the program’s only achievement was to enrich the legacy space contractors.

By early 2010, after spending a year assessing the state of play, the Obama administration sought to cancel Constellation. It ran into serious congressional pushback, powered by lobbying from Boeing, Lockheed Martin, Northrop Grumman, and other key legacy contractors.

The Obama White House wanted to cancel both the rocket and the spacecraft and hold a competition for the private sector to develop a heavy lift vehicle. Their thinking: Only with lower-cost access to space could the nation afford to have a sustainable deep space exploration plan. In retrospect, it was the smart idea, but Congress was not having it. In 2011, Congress saved Orion and ordered a slightly modified rocket—it would still be based on space shuttle architecture to protect key contractors—that became the Space Launch System.

Then the Obama administration, with its NASA leader Charles Bolden, cast about for something to do with this hardware. They started talking about a “Journey to Mars.” But it was all nonsense. There was never any there there. Essentially, NASA lost a decade, spending billions of dollars a year developing “exploration” systems for humans and talking about fanciful missions to the red planet.

There were critics of this approach, myself included. In 2014, I authored a seven-part series at the Houston Chronicle called Adrift, the title referring to the direction of NASA’s deep space ambitions. The fundamental problem is that NASA, at the direction of Congress, was spending all of its exploration funds developing Orion, the SLS rocket, and ground systems for some future mission. This made the big contractors happy, but their cost-plus contracts gobbled up so much funding that NASA had no money to spend on payloads or things to actually fly on this hardware.

This is why doubters called the SLS the “rocket to nowhere.” They were, sadly, correct.

The Moon, finally

Fairly early on in the first Trump administration, the new leader of NASA, Jim Bridenstine, managed to ditch the Journey to Mars and establish a lunar program. However, any efforts to consider alternatives to the SLS rocket were quickly rebuffed by the US Senate.

During his tenure, Bridenstine established the Artemis Program to return humans to the Moon. But Congress was slow to open its purse for elements of the program that would not clearly benefit a traditional contractor or NASA field center. Consequently, the space agency did not select a lunar lander until April 2021, after Bridenstine had left office. And NASA did not begin funding work on this until late 2021 due to a protest by Blue Origin. The space agency did not support a lunar spacesuit program for another year.

Much has been made about the selection of SpaceX as the sole provider of a lunar lander. Was it shady? Was the decision rushed before Bill Nelson was confirmed as NASA administrator? In truth, SpaceX was the only company that bid a value that NASA could afford with its paltry budget for a lunar lander (again, Congress prioritized SLS funding), and which had the capability the agency required.

To be clear, for a decade, NASA spent in excess of $3 billion a year on the development of the SLS rocket and its ground systems. That’s every year for a rocket that used main engines from the space shuttle, a similar version of its solid rocket boosters, and had a core stage the same diameter as the shuttle’s external tank. Thirty billion bucks for a rocket highly derivative of a vehicle NASA flew for three decades. SpaceX was awarded less than a single year of this funding, $2.9 billion, for the entire development of a Human Landing System version of Starship, plus two missions.

So yes, after 20 years, Orion appears to be ready to carry NASA astronauts out to the Moon. After 15 years, the shuttle-derived rocket appears to work. And after four years (and less than a tenth of the funding), Starship is not ready to land humans on the Moon.

When will Starship be ready?

Probably not any time soon.

For SpaceX and its founder, Elon Musk, the Artemis Program is a sidequest to the company’s real mission of sending humans to Mars. It simply is not a priority (and frankly, the limited funding from NASA does not compel prioritization). Due to its incredible ambition, the Starship program has also understandably hit some technical snags.

Unfortunately for NASA and the country, Starship still has a long way to go to land humans on the Moon. It must begin flying frequently (this could happen next year, finally). It must demonstrate the capability to transfer and store large amounts of cryogenic propellant in space. It must land on the Moon, a real challenge for such a tall vehicle, necessitating a flat surface that is difficult to find near the poles. And then it must demonstrate the ability to launch from the Moon, which would be unprecedented for cryogenic propellants.

Perhaps the biggest hurdle is the complexity of the mission. To fully fuel a Starship in low-Earth orbit to land on the Moon and take off would require multiple Starship “tanker” launches from Earth. No one can quite say how many because SpaceX is still working to increase the payload capacity of Starship, and no one has real-world data on transfer efficiency and propellant boiloff. But the number is probably at least a dozen missions. One senior source recently suggested to Ars that it may be as many as 20 to 40 launches.

The bottom line: It’s a lot. SpaceX is far and away the highest-performing space company in the Solar System. But putting all of the pieces together for a lunar landing will require time. Privately, SpaceX officials are telling NASA it can meet a 2028 timeline for Starship readiness for Artemis astronauts.

But that seems very optimistic. Very. It’s not something I would feel comfortable betting on, especially if China plans to land on the Moon “before” 2030, and the country continues to make credible progress toward this date.

What are the alternatives?

Duffy’s continued public insistence that he will not let China beat the United States back to the Moon rings hollow. The shrewd people in the industry I’ve spoken with say Duffy is an intelligent person and is starting to realize that betting the entire farm on SpaceX at this point would be a mistake. It would be nice to have a plan B.

But please, stop gaslighting us. Stop blustering about how we’re going to beat China while losing a quarter of NASA’s workforce and watching your key contractors struggle with growing pains. Let’s have an honest discussion about the challenges and how we’ll solve them.

What few people have done is offer solutions to Duffy’s conundrum. Fortunately, we’re here to help. As I have conducted interviews in recent weeks, I have always closed by asking this question: “You’re named NASA administrator tomorrow. You have one job: get NASA astronauts safely back to the Moon before China. What do you do?”

I’ve received a number of responses, which I’ll boil down into the following buckets. None of these strike me as particularly practical solutions, which underscores the desperation of NASA’s predicament. However, recent reporting has uncovered one solution that probably would work. I’ll address that last. First, the other ideas:

  • Stubby Starship: Multiple people have suggested this option. Tim Dodd has even spoken about it publicly. Two of the biggest issues with Starship are the need for many refuelings and its height, making it difficult to land on uneven terrain. NASA does not need Starship’s incredible capability to land 100–200 metric tons on the lunar surface. It needs fewer than 10 tons for initial human missions. So shorten Starship, reduce its capability, and get it down to a handful of refuelings. It’s not clear how feasible this would be beyond armchair engineering. But the larger problem is that Musk wants Starship to get taller, not shorter, so SpaceX would probably not be willing to do this.
  • Surge CLPS funding: Since 2019, NASA has been awarding relatively small amounts of funding to private companies to land a few hundred kilograms of cargo on the Moon. NASA could dramatically increase funding to this program, say up to $10 billion, and offer prizes for the first and second companies to land two humans on the Moon. This would open the competition to other companies beyond SpaceX and Blue Origin, such as Firefly, Intuitive Machines, and Astrobotic. The problem is that time is running short, and scaling up from 100 kilograms to 10 metric tons is an extraordinary challenge.
  • Build the Lunar Module: NASA already landed humans on the Moon in the 1960s with a Lunar Module built by Grumman. Why not just build something similar again? In fact, some traditional contractors have been telling NASA and Trump officials this is the best option, that such a solution, with enough funding and cost-plus guarantees, could be built in two or three years. The problem with this is that, sorry, the traditional space industry just isn’t up to the task. It took more than a decade to build a relatively simple rocket based on the space shuttle. The idea that a traditional contractor will complete a Lunar Module in five years or less is not supported by any evidence in the last 20 years. The flimsy Lunar Module would also likely not pass NASA’s present-day safety standards.
  • Distract China: I include this only for completeness. As for how to distract China, use your imagination. But I would submit that ULA snipers or starting a war in the South China Sea is not the best way to go about winning the space race.

OK, I read this far. What’s the answer?

The answer is Blue Origin’s Mark 1 lander.

The company has finished assembly of the first Mark 1 lander and will soon ship it from Florida to Johnson Space Center in Houston for vacuum chamber testing. A pathfinder mission is scheduled to launch in early 2026. It will be the largest vehicle to ever land on the Moon. It is not rated for humans, however. It was designed as a cargo lander.

There have been some key recent developments, though. About two weeks ago, NASA announced that a second mission of Mark 1 will carry the VIPER rover to the Moon’s surface in 2027. This means that Blue Origin intends to start a production line of Mark 1 landers.

At the same time, Blue Origin already has a contract with NASA to develop the much larger Mark 2 lander, which is intended to carry humans to the lunar surface. Realistically, though, this will not be ready until sometime in the 2030s. Like SpaceX’s Starship, it will require multiple refueling launches. As part of this contract, Blue has worked extensively with NASA on a crew cabin for the Mark 2 lander.

Here comes the important part. Ars can now report, based on government sources, that Blue Origin has begun preliminary work on a modified version of the Mark 1 lander—leveraging learnings from Mark 2 crew development—that could be part of an architecture to land humans on the Moon this decade. NASA has not formally requested Blue Origin to work on this technology, but according to a space agency official, the company recognizes the urgency of the need.

How would it work? Blue Origin is still architecting the mission, but it would involve “multiple” Mark 1 landers to carry crew down to the lunar surface and then ascend back up to lunar orbit to rendezvous with the Orion spacecraft. Enough work has been done, according to the official, that Blue Origin engineers are confident the approach could work. Critically, it would not require any refueling.

It is unclear whether this solution has reached Duffy, but he would be smart to listen. According to sources, Blue Origin founder Jeff Bezos is intrigued by the idea. And why wouldn’t he be? For a quarter of a century, he has been hearing about how Musk has been kicking his ass in spaceflight. Bezos also loves the Apollo program and could now play an essential role in serving his country in an hour of need. He could beat SpaceX to the Moon and stamp his name in the history of spaceflight.

Jeff and Sean? Y’all need to talk.

A new report finds China’s space program will soon equal that of the US

As Jonathan Roll neared completion of a master’s degree in science and technology policy at Arizona State University three years ago, he did some research into recent developments by China’s ascendant space program. He came away impressed by the country’s growing ambitions.

Now a full-time research analyst at the university, Roll was recently asked to take a deeper dive into Chinese space plans.

“I thought I had a pretty good read on this when I was finishing grad school,” Roll told Ars. “That almost everything needed to be updated, or had changed three years later, was pretty scary. On all these fronts, they’ve made pretty significant progress. They are taking all of the cues from our Western system about what’s really galvanized innovation, and they are off to the races with it.”

Roll is the co-author of a new report, titled “Redshift,” on the acceleration of China’s commercial and civil space activities, and the threat these pose to similar efforts in the United States. Published on Tuesday, the report was sponsored by the US-based Commercial Space Federation, which advocates for the country’s commercial space industry. It is a sobering read, and comes as China not only projects to land humans on the lunar surface before the US can return, but is advancing across several spaceflight fronts to challenge America.

“The trend line is unmistakable,” the report states. “China is not only racing to catch up—it is setting pace, deregulating, and, at times, redefining what leadership looks like on and above Earth. This new space race will not be won with a single breakthrough or headline achievement, but with sustained commitment, clear-eyed vigilance, and a willingness to adapt over decades.”

NASA’s acting chief “angry” about talk that China will beat US back to the Moon

NASA’s interim administrator, Sean Duffy, said Thursday he has heard the recent talk about how some people are starting to believe that China will land humans on the Moon before NASA can return there with the Artemis Program.

“We had testimony that said NASA will not beat China to the Moon,” Duffy remarked during an all-hands meeting with NASA employees. “That was shade thrown on all of NASA. I heard it, and I gotta tell you what, maybe I am competitive, I was angry about it. I can tell you what, I’ll be damned if that is the story that we write. We are going to beat the Chinese to the Moon.”

Duffy’s remarks followed a Congressional hearing on Wednesday during which former Congressman Jim Bridenstine, who served as NASA administrator during President Trump’s first term, said China had pulled ahead of NASA and the United States in the second space race.

“Unless something changes, it is highly unlikely the United States will beat China’s projected timeline to the Moon’s surface,” said Bridenstine, who led the creation of the Artemis Program in 2019. China has said multiple times that it intends to land taikonuats on the Moon before the year 2030.

A lot of TV appearances

Duffy’s remarks were characteristic of his tenure since his appointment two months ago by Trump to serve as interim administrator of the space agency. He has made frequent appearances on Fox News and offered generally upbeat views of NASA’s position in its competition with China for supremacy in space. And on Friday, in a slickly produced video, he said, “I’m committed to getting us back to the Moon before President Trump leaves office.”

Sources have said Duffy, already a cabinet member as the secretary of transportation, is also angling to remove the “interim” from his NASA administrator title. Like Bridenstine, he has a capable political background and politics that align with the Trump administration. He is an excellent public speaker and knows the value of speaking to the president through Fox News. To date, however, he has shown limited recognition of the reality of the current competition with China.

Former NASA chief says United States likely to lose second lunar space race

The hearing, titled “There’s a Bad Moon on the Rise: Why Congress and NASA Must Thwart China in the Space Race,” had no witnesses who disagreed with this viewpoint. They included Allen Cutler, CEO of the Coalition for Deep Space Exploration, the chief lobbying organization for SLS, Orion, and Gateway; Jim Bridenstine, former NASA Administrator who now leads government operations for United Launch Alliance; Mike Gold of Redwire, a Gateway contractor; and Lt. General John Shaw, former Space Command official.

The hearing before the committee chaired by Cruz, Commerce, Science, and Transportation, included the usual mishmash of parochial politics, lobbying for traditional space, back slapping, and fawning—at one point, Gold, a Star Trek fan, went so far as to assert that Cruz is the “Captain Kirk” of the US Senate.

Beyond this, however, there was a fair amount of teeth gnashing about the fact that the United States faces a serious threat from China, which appears to be on course to put humans on the Moon before NASA can return there with the Artemis Program. China aims to land humans at the South Pole before the year 2030.

NASA likely to lose “race”

Bridenstine, who oversaw the creation of the Artemis Program half a decade ago, put it most bluntly: “Unless something changes, it is highly unlikely the United States will beat China’s projected timeline to the Moon’s surface,” he said.

Bridenstine and others on the panel criticized the complex nature of SpaceX’s Starship-based lunar lander, which NASA selected in April 2021 as a means to get astronauts down to the lunar surface and back. The proposal relies on Starship being refueled in low-Earth orbit by multiple Starship tanker launches.

Time is running out for SpaceX to make a splash with second-gen Starship


SpaceX is gearing up for another Starship launch after three straight disappointing test flights.

STARBASE, Texas—A beehive of aerospace technicians, construction workers, and spaceflight fans descended on South Texas this weekend in advance of the next test flight of SpaceX’s gigantic Starship rocket, the largest vehicle of its kind ever built.

Towering 404 feet (123.1 meters) tall, the rocket was supposed to lift off during a one-hour launch window beginning at 6: 30 pm CDT (7: 30 pm EDT; 23: 30 UTC) Sunday. But SpaceX called off the launch attempt about an hour before liftoff to investigate a ground system issue at Starbase, located a few miles north of the US-Mexico border.

SpaceX didn’t immediately confirm when it might try again to launch Starship, but it could happen as soon as Monday evening at the same time.

It will take about 66 minutes for the rocket to travel from the launch pad in Texas to a splashdown zone in the Indian Ocean northwest of Australia. You can watch the test flight live on SpaceX’s official website. We’ve also embedded a livestream from Spaceflight Now and LabPadre below.

This will be the 10th full-scale test flight of Starship and its Super Heavy booster stage. It’s the fourth flight of an upgraded version of Starship conceived as a stepping stone to a more reliable, heavier-duty version of the rocket designed to carry up to 150 metric tons, or some 330,000 pounds, of cargo to pretty much anywhere in the inner part of our Solar System.

But this iteration of Starship, known as Block 2 or Version 2, has been anything but reliable. After reeling off a series of increasingly successful flights last year with the first-generation Starship and Super Heavy booster, SpaceX has encountered repeated setbacks since debuting Starship Version 2 in January.

Now, there are just two Starship Version 2s left to fly, including the vehicle poised for launch this week. Then, SpaceX will move on to Version 3, the design intended to go all the way to low-Earth orbit, where it can be refueled for longer expeditions into deep space.

Starship’s promised cargo capacity is unparalleled in the history of rocketry. The privately developed rocket’s enormous size, coupled with SpaceX’s plan to make it fully reusable, could enable cargo and human missions to the Moon and Mars. SpaceX’s most conspicuous contract for Starship is with NASA, which plans to use a version of the ship as a human-rated Moon lander for the agency’s Artemis program. With this contract, Starship is central to the US government’s plans to try to beat China back to the Moon.

Closer to home, SpaceX intends to use Starship to haul massive loads of more powerful Starlink Internet satellites into low-Earth orbit. The US military is interested in using Starship for a range of national security missions, some of which could scarcely be imagined just a few years ago. SpaceX wants its factory to churn out a Starship rocket every day, approximately the same rate Boeing builds its workhorse 737 passenger jets.

Starship, of course, is immeasurably more complex than an airliner, and it sees temperature extremes, aerodynamic loads, and vibrations that would destroy a commercial airplane.

For any of this to become reality, SpaceX needs to begin ticking off a lengthy to-do list of technical milestones. The interim objectives include things like catching and reusing Starships and in-orbit ship-to-ship refueling, with a final goal of long-duration spaceflight to reach the Moon and stay there for weeks, months, or years. For a time late last year, it appeared as if SpaceX might be on track to reach at least the first two of these milestones by now.

Instead, SpaceX’s schedule for catching and reusing Starships, and refueling ships in orbit, has slipped well into next year. A Moon landing is probably at least several years away. And a touchdown on Mars? Maybe in the 2030s. Before Starship can sniff those milestones, engineers must get the rocket to survive from liftoff through splashdown. This would confirm that recent changes made to the ship’s heat shield work as expected.

Three test flights attempting to do just this ended prematurely in January, March, and May. These failures prevented SpaceX from gathering data on several different tile designs, including insulators made of ceramic and metallic materials, and a tile with “active cooling” to fortify the craft as it reenters the atmosphere.

The heat shield is supposed to protect the rocket’s stainless steel skin from temperatures reaching 2,600° Fahrenheit (1,430° Celsius). During last year’s test flights, it worked well enough for Starship to guide itself to an on-target controlled splashdown in the Indian Ocean, halfway around the world from SpaceX’s launch site in Starbase, Texas.

But the ship lost some of its tiles during each flight last year, causing damage to the ship’s underlying structure. While this wasn’t bad enough to prevent the vehicle from reaching the ocean intact, it would cause difficulties in refurbishing the rocket for another flight. Eventually, SpaceX wants to catch Starships returning from space with giant robotic arms back at the launch pad. The vision, according to SpaceX founder and CEO Elon Musk, is to recover the ship, quickly mount it on another booster, refuel it, and launch it again.

If SpaceX can accomplish this, the ship must return from space with its heat shield in pristine condition. The evidence from last year’s test flights showed engineers had a long way to go for that to happen.

The Starship setbacks this year have been caused by problems in the ship’s propulsion and fuel systems. Another Starship exploded on a test stand in June at SpaceX’s sprawling rocket development facility in South Texas. SpaceX engineers identified different causes for each of the failures. You can read about them in our previous story.

Apart from testing the heat shield, the goals for this week’s Starship flight include testing an engine-out capability on the Super Heavy booster. Engineers will intentionally disable one of the booster’s Raptor engines used to slow down for landing, and instead use another Raptor engine from the rocket’s middle ring. At liftoff, 33 methane-fueled Raptor engines will power the Super Heavy booster off the pad.

SpaceX won’t try to catch the booster back at the launch pad this time, as it did on three occasions late last year and earlier this year. The booster catches have been one of the bright spots for the Starship program as progress on the rocket’s upper stage floundered. SpaceX reused a previously flown Super Heavy booster for the first time on the most recent Starship launch in May.

The booster landing experiment on this week’s flight will happen a few minutes after launch over the Gulf of Mexico east of the Texas coastline. Meanwhile, six Raptor engines will fire until approximately T+plus 9 minutes to accelerate the ship, or upper stage, into space.

The ship is programmed to release eight Starlink satellite simulators from its payload bay in a test of the craft’s payload deployment mechanism. That will be followed by a brief restart of one of the ship’s Raptor engines to adjust its trajectory for reentry, set to begin around 47 minutes into the mission.

If Starship makes it that far, that will be when engineers finally get a taste of the heat shield data they were hungry for at the start of the year.
