Notably, the company plans to launch each new rocket as soon as it is ready to fly to gather data about the vehicle’s performance, attempt to catch and reuse first stages, and move closer to a rapid launch cadence. Therefore, if a customer payload is not ready, the company has also developed an inspirational mission called “Cube for the Future,” which appears to be part of the company’s initiative to inspire future generations to pursue careers in science. This may also fly as a rideshare on one of the launches listed above.

All eyes on the Moon

Among these missions, the payload likely to spark the most interest is the Blue Moon MK1 lander, which is part of the company’s plans to develop a large, reusable lander capable of landing humans on the Moon.

Blue Origin shared a snippet of video last week on social media showing the mid-section of the MK1 lander arriving at the company’s assembly facilities in Rocket Park, Florida. This will be the tallest vehicle ever to land on the Moon. It is 8 meters (26.4 feet) tall, which is 1 meter taller than the Lunar Module NASA used to land humans during the Apollo Program.

MK1 is a cargo version of a larger vehicle, MK2, that Blue Origin is developing for humans. The cargo version is rated to carry about 3 metric tons to the surface, about 10 times the capacity of currently available commercial landers available to NASA.

Barring a major setback, it now appears highly likely that Blue Origin will beat SpaceX in landing a vehicle on the lunar surface. Due to the struggles with development of the Starship vehicle—whether on the ground or in space, the last four Starship upper stages have been lost before achieving a nominal success—some industry officials believe Blue Origin now has a realistic chance to compete with SpaceX in the effort to land NASA astronauts on the Moon as part of the Artemis Program.

Both companies are developing large, ambitious vehicles—SpaceX with Starship, and Blue Origin with its MK2 lander—but Blue Origin’s vehicle is somewhat less technically challenging. Blue Origin founder Jeff Bezos is also far more committed to a lunar program than SpaceX founder Elon Musk, sources said, and if he sees an opportunity to finally best his rival in space, he may go for it.

Welcome to Edition 7.50 of the Rocket Report! We’re nearly halfway through the year, and it seems like a good time to look back on the past six months. What has been most surprising to me in the world of rockets? First, I didn’t expect SpaceX to have this much trouble with Starship Version 2. Growing pains are normal for new rockets, but I expected the next big hurdles for SpaceX to clear with Starship to be catching the ship from orbit and orbital refueling, not completing a successful launch. The state of Blue Origin’s New Glenn program is a little surprising to me. New Glenn’s first launch in January went remarkably well, beating the odds for a new rocket. Now, production delays are pushing back the next New Glenn flights. The flight of Honda’s reusable rocket hopper also came out of nowhere a few weeks ago.

Isar raises 150 million euros. German space startup Isar Aerospace has obtained 150 million euros ($175 million) in funding from an American investment company, Reuters reports. The company, which specializes in satellite launch services, signed an agreement for a convertible bond with Eldridge Industries, it said. Isar says it will use the funding to expand its launch service offerings. Isar’s main product is the Spectrum rocket, a two-stage vehicle designed to loft up to a metric ton (2,200 pounds) of payload mass to low-Earth orbit. Spectrum flew for the first time in March, but it failed moments after liftoff and fell back to the ground near its launch pad. Still, Isar became the first in a new crop of European launch startups to launch a rocket theoretically capable of reaching orbit.

Flush with cash … Isar is leading in another metric, too. The Munich-based company has now raised more than 550 million euros ($642 million) from venture capital investors and government-backed funds. This far exceeds the fundraising achievements of any other European launch startup. But the money will only go so far before Isar must prove it can successfully launch a rocket into orbit. Company officials have said they aim to launch the second Spectrum rocket before the end of this year. (submitted by EllPeaTea)

Rocket Lab aiming for record turnaround. Rocket Lab demonstrated a notable degree of flexibility this week. Two light-class Electron rockets were nearing launch readiness at the company’s privately owned spaceport in New Zealand, but one of the missions encountered a technical problem, and Rocket Lab scrubbed a launch attempt Tuesday. The spaceport has two launch pads next to one another, so while technicians worked to fix that problem, Rocket Lab slotted in another Electron rocket to lift off from the pad next door. That mission, carrying a quartet of small commercial signals intelligence satellites for HawkEye 360, successfully launched Thursday.

Giving it another go … A couple of hours after that launch, Rocket Lab announced it was ready to try again with the mission it had grounded earlier in the week. “Can’t get enough of Electron missions? How about another one tomorrow? With our 67th mission complete, we’ve scheduled our next launch from LC-1 in less than 48 hours—Electron’s fastest turnaround from the same launch site yet!” Rocket Lab hasn’t disclosed what satellite is flying on this mission, citing the customer’s preference to remain anonymous for now.

You guessed it! Baguette One will launch from France. French rocket builder HyPrSpace will launch its Baguette One demonstrator from a missile testing site in mainland France, after signing an agreement with the country’s defense procurement agency, European Spaceflight reports. HyPrSpace was founded in 2019 to begin designing an orbital-class rocket named Orbital Baguette 1 (OB-1). The Baguette One vehicle is a subscale, single-stage suborbital demonstrator to prove out technologies for the larger satellite launcher, mainly its hybrid propulsion system.

Sovereign launch … HyPrSpace’s Baguette One will stand roughly 10 meters (30 feet) tall and will be capable of carrying payloads of up to 300 kilograms (660 pounds) to suborbital space. It is scheduled to launch next year from a French missile testing site in the south of France. “Gaining access to this dual-use launch pad in mainland France is a major achievement after many years of work on our hybrid propulsion technology,” said Sylvain Bataillard, director general of HyPrSpace. “It’s a unique opportunity for HyPrSpace and marks a decisive turning point. We’re eager to launch Baguette One and to play a key role in building a more sovereign, more sustainable, and boldly innovative European dual-use space industry.” (submitted by EllPeaTea)

Firefly moves closer to launching from Sweden. An agreement between the United States and Sweden brings Firefly Aerospace one step closer to launching its Alpha rocket from a Swedish spaceport, Space News reports. The two countries signed a technology safeguards agreement (TSA) at a June 20 ceremony at the Swedish embassy in Washington, DC. The TSA allows the export of American rockets to Sweden for launches there, putting in place measures to protect launch vehicle technology.

A special relationship … The US government has signed launch-related safeguard agreements with only a handful of countries, such as Australia, the United Kingdom, and now Sweden. Rocket exports are subject to strict controls because of the potential military applications of that technology. Firefly currently launches its Alpha rocket from Vandenberg Space Force Base, California, and is building a launch site at Wallops Island, Virginia. Firefly also has a lease for a launch pad at Cape Canaveral, Florida, although the company is prioritizing other sites. Then, last year, Firefly announced an agreement with the Swedish Space Corporation to launch Alpha from Esrange Space Center as soon as 2026. (submitted by EllPeaTea)

Amazon is running strong out of the gate. For the second time in two months, United Launch Alliance sent a batch of 27 broadband Internet satellites into orbit for Amazon on Monday morning, Ars reports. This was the second launch of a full load of operational satellites for Amazon’s Project Kuiper, a network envisioned to become a competitor to SpaceX’s Starlink. Just like the last flight on April 28, an Atlas V rocket lifted off from Cape Canaveral, Florida, and delivered Amazon’s satellites into an on-target orbit roughly 280 miles (450 kilometers) above Earth.

Time to put up or shut up … After lengthy production delays at Amazon’s satellite factory, the retail giant is finally churning out Kuiper satellites at scale. Amazon has already shipped the third batch of Kuiper satellites to Florida to prepare for launch on a SpaceX Falcon 9 rocket next month. ULA won the lion’s share of Amazon’s multibillion-dollar launch contract in 2022, committing to up to 38 Vulcan launches for Kuiper and nine Atlas V flights. Three of those Atlas Vs have now launched. Amazon also reserved 18 launches on Europe’s Ariane 6 rocket, and at least 12 on Blue Origin’s New Glenn. Vulcan, Ariane 6, and New Glenn have only flown one or two times, and Amazon is asking them to quickly ramp up their cadence to deliver 3,232 Kuiper satellites to orbit in the next few years. The handful of Falcon 9s and Atlas Vs that Amazon has on contract are the only rockets in the bunch with a proven track record. With Kuiper satellites now regularly shipping out of the factory, any blame for future delays may shift from Amazon to the relatively unproven rockets it has chosen to launch them.

Falcon 9 launches with four commercial astronauts. Retired astronaut Peggy Whitson, America’s most experienced space flier, and three rookie crewmates from India, Poland, and Hungary blasted off on a privately financed flight to the International Space Station early Wednesday, CBS News reports. This is the fourth non-government mission mounted by Houston-based Axiom Space. The four commercial astronauts rocketed into orbit on a SpaceX Falcon 9 launcher from NASA’s Kennedy Space Center in Florida, and their Dragon capsule docked at the space station Thursday to kick off a two-week stay.

A brand-new Dragon … The Crew Dragon spacecraft flown on this mission, serial number C213, is the fifth and final addition to SpaceX’s fleet of astronaut ferry ships built for NASA trips to the space station and for privately funded commercial missions to low-Earth orbit. Moments after reaching orbit Wednesday, Whitson revealed the name of the new spacecraft: Crew Dragon Grace. “We had an incredible ride uphill, and now we’d like to set our course for the International Space Station aboard the newest member of the Dragon fleet, our spacecraft named Grace. … Grace reminds us that spaceflight is not just a feat of engineering, but an act of goodwill to the benefit of every human everywhere.”

How soon until Ariane 6 is flying regularly? It’ll take several years for Arianespace to ramp up the launch cadence of Europe’s new Ariane 6 rocket, Space News reports. David Cavaillolès, chief executive of Arianespace, addressed questions at the Paris Air Show about how quickly Arianespace can reach its target of launching 10 Ariane 6 rockets per year. “We need to go to 10 launches per year for Ariane 6 as soon as possible,” he said. “It’s twice as more as for Ariane 5, so it’s a big industrial change.” Two Ariane 6 rockets have launched so far, and a third mission is on track to lift off in August. Arianespace’s CEO reiterated earlier plans to conduct four more Ariane 6 launches through the end of this year, including the first flight of the more powerful Ariane 64 variant with four solid rocket boosters.

Not a heavy lift … Arianespace’s target flight rate of 10 Ariane 6 rockets per year is modest compared to other established companies with similarly sized launch vehicles. United Launch Alliance is seeking to launch as many as 25 Vulcan rockets per year. Blue Origin’s New Glenn is designed to eventually fly often, although the company hasn’t released a target launch cadence. SpaceX, meanwhile, aims to launch up to 170 Falcon 9 rockets this year. But European governments are perhaps more committed than ever to maintaining a sovereign launch capability for the continent, so Ariane 6 isn’t going away. Arianespace has sold more than 30 Ariane 6 launches, primarily to European institutional customers and Amazon.

SLS booster blows its nozzle. NASA and Northrop Grumman test-fired a new solid rocket booster in Utah on Thursday, and it didn’t go exactly according to plan, Ars reports. This booster features a new design that NASA would use to power Space Launch System rockets, beginning with the ninth mission, or Artemis IX. The motor tested on Thursday isn’t flight-worthy. It’s a test unit that engineers will use to learn about the rocket’s performance. It turns out they did learn something, but perhaps not what they wanted. About 1 minute and 40 seconds into the booster’s burn, a fiery plume emerged from the motor’s structure just above its nozzle. Moments later, the nozzle violently disintegrated. The booster kept firing until it ran out of pre-packed solid propellant.

A questionable future … NASA’s Space Launch System appears to have a finite shelf life. The Trump administration wants to cancel it after just three launches, while the preliminary text of a bill making its way through Congress would extend it to five flights. But chances are low the Space Launch System will make it to nine flights, and if it does, it’s questionable if it would reach that point before 2040. The SLS rocket is a core piece of NASA’s plan to return US astronauts to the Moon under the Artemis program, but the White House seeks to cancel the program in favor of cheaper commercial alternatives.

NASA conducts a low-key RS-25 engine test. The booster ground test on Thursday was the second time in less than a week that NASA test-fired new propulsion hardware for the Space Launch System. Last Friday, June 20, NASA ignited a new RS-25 engine on a test stand at Stennis Space Center in Mississippi. The hydrogen-fueled engine is the first of its kind to be manufactured since the end of the space shuttle program. This particular RS-25 engine is assigned to power the fifth launch of the SLS rocket, a mission known as Artemis V, that may end up never flying. While NASA typically livestreams engine tests at Stennis, the agency didn’t publicize this event ahead of time.

It has been 10 years … The SLS rocket was designed to recycle leftover parts from the space shuttle program, but NASA will run out of RS-25 engines after the rocket’s fourth flight and will exhaust its inventory of solid rocket booster casings after the eighth flight. Recognizing that shuttle-era parts will eventually run out, NASA signed a contract with Aerojet Rocketdyne (now L3Harris) to set the stage for the production of new RS-25 engines in 2015. NASA later ordered an initial batch of six RS-25 engines from Aerojet, then added 18 more to the order in 2020, at a price of about $100 million per engine. Finally, a brand-new flight-worthy RS-25 engine has fired up on a test stand. If the Trump administration gets its way, these engines will never fly. Maybe that’s fine, but after so long with so much taxpayer investment, last week’s test milestone is worth publicizing, if not celebrating.

SpaceX finds itself in a dustup on the border. President Claudia Sheinbaum of Mexico is considering taking legal action after one of SpaceX’s giant Starship rockets disintegrated in a giant fireball earlier this month as it was being fueled for a test-firing of its engines, The New York Times reports. No one was injured in the explosion, which rained debris on the beaches of the northern Mexican state of Tamaulipas. The conflagration occurred at a test site SpaceX operates a few miles away from the Starship launch pad. This test facility is located next to the Rio Grande River, just a few hundred feet from Mexico. The power of the blast sent wreckage flying across the river into Mexican territory.

Collision course …“We are reviewing everything related to the launching of rockets that are very close to our border,” Sheinbaum said at a news conference Wednesday. If SpaceX violated any international laws, she added, “we will file any necessary claims.” Sheinbaum’s leftist party holds enormous sway around Mexico, and the Times reports she was responding to calls to take action against SpaceX amid a growing outcry among scientists, regional officials, and environmental activists over the impact that the company’s operations are having on Mexican ecosystems. SpaceX, on the other hand, said its efforts to recover debris from the Starship explosion have been “hindered by unauthorized parties trespassing on private property.” SpaceX said it requested assistance from the government of Mexico in the recovery and added that it offered its own resources to help with the cleanup.

An exceedingly rare asteroid flyby will happen soon, but NASA may be left on the sidelines

A little less than four years from now, a killer asteroid will narrowly fly past planet Earth. This will be a celestial event visible around the world—for a few weeks, Apophis will shine among the brightest objects in the night sky.

The near miss by the large Apophis asteroid in April 2029 offers NASA a golden—and exceedingly rare—opportunity to observe such an object like this up close. Critically, the interaction between Apophis and Earth’s gravitational pull will offer scientists an unprecedented chance to study the interior of an asteroid.

This is fascinating for planetary science, but it also has serious implications for planetary defense. In the future, were such an asteroid on course to strike Earth, an effective plan to deflect it would depend on knowing what the interior looks like.

“This is a remarkable opportunity,” said Bobby Braun, who leads space exploration for the Johns Hopkins Applied Physics Laboratory, in an interview. “From a probability standpoint, there’s not going to be another chance to study a killer asteroid like this for thousands of years. Sooner or later, we’re going to need this knowledge.”

But we may not get it.

NASA has some options for tracking Apophis during its flyby. However, the most promising of these, a mission named OSIRIS-Apex that breathes new life into an old spacecraft that otherwise would drift into oblivion, is slated for cancellation by the Trump White House’s budget for fiscal year 2026.

Other choices, including dragging dual space probes out of storage, the Janus spacecraft, and other concepts that were submitted to NASA a year ago as part of a call for ideas, have already been rejected or simply left on the table. As a result, NASA currently has no plans to study what will be the most important asteroid encounter since the formation of the space agency.

“The world is watching,” said Richard Binzel, an asteroid expert at the Massachusetts Institute of Technology. “NASA needs to step up and do their job.”

But will they?

A short history of planetary defense

For decades, nearly every public survey asking what NASA should work on has rated planetary defense at or near the very top of the space agency’s priorities. Yet for a long time, no part of NASA actually focused on finding killer asteroids or developing the technology to deflect them.

In authorization bills dating back to 2005, Congress began mandating that NASA “detect, track, catalog, and characterize” near-Earth objects that were 140 meters in diameter or larger. Congress established a goal of finding 90 percent of these by the year 2020. (We’ve blown past that deadline, obviously.)

NASA had been informally studying asteroids and comets for decades but did not focus on planetary defense until 2016, when the space agency established the Planetary Defense Coordination Office. In the decade since, NASA has made some progress, identifying more than 26,000 near-Earth objects, which are defined as asteroids and comets that come within 30 million miles of our planet’s orbit.

Moreover, NASA has finally funded a space mission designed specifically to look for near-Earth threats, NEO Surveyor, a space telescope with the goal of “finding asteroids before they find us.” The $1.2 billion mission is due to launch no earlier than September 2027.

NASA also funded the DART mission, which launched in 2021 and impacted a 160-meter asteroid named Dimorphous a year later to demonstrate the ability to make a minor deflection.

But in a report published this week, NASA’s Office of Inspector General found that despite these advances, the space agency’s approach to planetary defense still faces some significant challenges. These include a lack of resources, a need for better strategic planning, and competition with NASA’s more established science programs for limited funding.

A comprehensive plan to address planetary defense must include two elements, said Ed Lu, a former NASA astronaut who co-founded the B612 Foundation to protect Earth from asteroid impacts.

The first of these is the finding and detection of asteroid threats. That is being addressed both by the forthcoming NEO Surveyor and the recently completed Vera C. Rubin Observatory, which is likely to find thousands of new near-Earth threats. The challenge in the coming years will be processing all of this data, calculating orbits, and identifying threats. Lu said NASA must do a better job of being transparent in how it makes these calculations.

The second thing Lu urged NASA to do is develop a follow-up mission to DART. It was successful, he said, but DART was just an initial demonstration. Such a capability needs to be tested against a larger asteroid with different properties.

An asteroid that might look a lot like Apophis.

About Apophis

Astronomers using a telescope in Arizona found Apophis in 2004, and they were evidently fans of the television series Stargate SG-1, in which a primary villain who threatens civilization on Earth is named Apophis.

Because of its orbit, Apophis comes near Earth about every eight years. It is fairly large, about 370 meters across. This is not big enough to wipe out civilization on Earth, but it would cause devastating consequences across a large region, imparting about 300 times as much impact force on the planet as the Tunguska event in 1908, over Siberia. It will miss Earth by about 31,600 km (19,600 miles) on April 13, 2029.

“We like to say that’s because nature has a sense of humor,” said Binzel, the MIT asteroid scientist, of this date.

Astronomers estimate that an asteroid this large comes this close to Earth only about once every 7,500 years. It also appears to be a stony, non-metallic type of asteroid known as an ordinary chondrite. This is the most common type of asteroid in the Solar System.

All of this is rather convenient for scientists hoping to understand more about potential asteroids that might pose a serious threat to the planet.

The real cherry on top with the forthcoming encounter is that Apophis will be perturbed by Earth’s gravitational pull.

“Nature is handing us an incredibly rare experiment where the Earth’s gravity is going to tug and stretch this asteroid,” Binzel said. “By seeing how the asteroid responds, we’ll know how it is put together, and knowing how an asteroid is put together is maybe the most important information we could have if humanity ever faces an asteroid threat.”

In nearly seven decades of spaceflight, humans have only ever probed the interior of three celestial bodies: the Earth, the Moon, and Mars. We’re now being offered the opportunity to probe a fourth, right on our doorstep.

But time is ticking.

Chasing Apophis

On paper, at least, NASA has a plan to rendezvous with Apophis. About three years ago, after a senior-level review, NASA extended the mission of the OSIRIS-REx spacecraft to rendezvous with Apophis.

As you may recall, this oddly named spacecraft collected a sample from another asteroid, Bennu, in October 2020. Afterward, a small return capsule departed from the main spacecraft and made its way back to Earth. Since then, an $800 million spacecraft specifically designed to fly near and touch an asteroid has been chilling in space.

So it made sense when NASA decided to fire up the mission, newly rechristened OSIRIS-Apex, and re-vector it toward Apophis. It has been happily flying toward such a rendezvous for a few years. The plan was for Apex to catch up to Apophis shortly after its encounter with Earth and study it for about 18 months.

“The most cost-efficient thing you can do in spaceflight is continue with a heathy spacecraft that is already operating in space,” Binzel said.

And that was the plan until the Trump administration released its budget proposal for fiscal year 2026. In its detailed budget information, the White House provided no real rationale for the cancellation, simply stating, “Operating missions that have completed their prime missions (New Horizons and Juno) and the follow-on mission to OSIRIX-REx, OSIRIS-Apophis Explorer, are eliminated.”

It’s unclear how much of a savings this resulted in. However, Apex is a pittance in NASA’s overall budget. The operating funds to keep the mission alive in 2024, for example, were $14.5 million. Annual costs would be similar through the end of the decade. This is less than one-thousandth of NASA’s budget, by the way.

“Apex is already on its way to reach Apophis, and to turn it off would be an incredible waste of resources,” Binzel said.

Congress, of course, ultimately sets the budget. It will have the final say. But it’s clear that NASA’s primary mission to study a once-in-a-lifetime asteroid is at serious risk.

So what are the alternatives?

Going international and into the private sector

NASA was not the only space agency targeting Apophis. Nancy Chabot, a planetary scientist at the Johns Hopkins University Applied Physics Laboratory, has been closely tracking other approaches.

The European Space Agency has proposed a mission named Ramses to rendezvous with the asteroid and accompany it as it flies by Earth. This mission would be valuable, conducting a thorough before-and-after survey of the asteroid’s shape, surface, orbit, rotation, and orientation.

It would need to launch by April 2028. Recognizing this short deadline, the space agency has directed European scientists and engineers to begin preliminary work on the mission. But a final decision to proceed and commit to the mission will not be made before the space agency’s ministerial meeting in November.

This is no sure thing. For example, Chabot said, in 2016, the Asteroid Impact Mission was expected to advance before European ministers decided not to fund it. It is also not certain that the Ramses mission would be ready to fly in less than three years, a short timeline for planetary science missions.

Japan’s space agency, JAXA, is also planning an asteroid mission named Destiny+ that has as its primary goal flying to an asteroid named 3200 Phaeton. The mission has been delayed multiple times, so its launch is now being timed to permit a single flyby of Apophis in February 2029 on the way to its destination. While this mission is designed to deliver quality science, a flyby mission provides limited data. It is also unclear how close Destiny+ will actually get to Apophis, Chabot said.

There are also myriad other concepts, commercial and otherwise, to characterize Apophis before, during, and after its encounter with Earth. Ideally, scientists say, a mission would fly to the asteroid before April 2029 and scatter seismometers on the surface to collect data.

But all of this would require significant funding. If not from NASA, who? The uncertain future of NASA’s support for Apex has led some scientists to think about philanthropy.

For example, NASA’s Janus spacecraft have been mothballed for a couple of years, but they could be used for observational purposes if they had—say—a Falcon 9 to launch them at the appropriate time.

A new, private reconnaissance mission could probably be developed for $250 million or less, industry officials told Ars. There is still enough time, barely, for a private group to work with scientists to develop instrumentation that could be added to an off-the-shelf spacecraft bus to get out to Apophis before its Earth encounter.

Private astronaut Jared Isaacman, who has recently indicated a willingness to support robotic exploration in strategic circumstances, confirmed to Ars that several people have reached out about his interest in financially supporting an Apophis mission. “I would say that I’m in info-gathering mode and not really rushing into anything,” Isaacman said.

The problem is that, at this very moment, Apophis is rushing this way.

NASA tested a new SLS booster that may never fly, and the end of it blew off

NASA’s Space Launch System appears to have a finite shelf life. The Trump administration wants to cancel it after just three launches, while the preliminary text of a bill making its way through Congress would extend it to five flights.

But chances are low the Space Launch System will make it to nine flights, and if it does, it’s questionable that it would reach that point before 2040. The SLS rocket is a core piece of NASA’s plan to return US astronauts to the Moon under the Artemis program, but the White House seeks to cancel the program in favor of cheaper commercial alternatives.

For the second time in less than a week, NASA test-fired new propulsion hardware Thursday that the agency would need to keep SLS alive. Last Friday, a new liquid-fueled RS-25 engine ignited on a test stand at NASA’s Stennis Space Center in Mississippi. The hydrogen-fueled engine is the first of its kind to be manufactured since the end of the Space Shuttle program. This particular RS-25 engine is assigned to power the fifth flight of the SLS rocket, a mission known as Artemis V.

Then, on Thursday of this week, NASA and Northrop Grumman test-fired a new solid rocket booster in Utah. This booster features a new design that NASA would use to power SLS rockets beginning with the ninth mission, or Artemis IX. The motor tested on Thursday isn’t flight-worthy. It’s a test unit that engineers will use to gather data on the rocket’s performance.

While the engine test in Mississippi apparently went according to plan, the ground firing of the new solid rocket booster didn’t go quite as smoothly. Less than two minutes into the burn, the motor’s exhaust nozzle violently shattered into countless shards of debris. You can watch the moment in the YouTube video below.

At the start of the program nearly 15 years ago, NASA and its backers in Congress pitched the SLS rocket as the powerhouse behind a new era of deep space exploration. The Space Launch System, they said, would have the advantage of recycling old space shuttle engines and boosters, fast-tracking the new rocket’s path to the launch pad for less money than the cost of an all-new vehicle.

That didn’t pan out. Each Artemis mission costs $4.2 billion per flight, and that’s with shuttle-era engines and boosters that NASA and its contractors already have in their inventories. NASA’s 16 leftover shuttle main engines are enough for the first four SLS flights. NASA has leftover parts for eight pairs of solid rocket boosters.

It has been 10 years

Recognizing that shuttle-era parts will eventually run out, NASA signed a contract with Aerojet Rocketdyne to set the stage for the production of new RS-25 engines in 2015. NASA later ordered an initial batch of six RS-25 engines from Aerojet, then added 18 more to the order in 2020, at a price of about $100 million per engine. NASA and its contractor aim to reduce the cost to $70 million per engine, but even that figure is many times the cost of engines of comparable size and power: Blue Origin’s BE-4 and SpaceX’s Raptor.

Finally, NASA test-fired a new flight-rated RS-25 engine for the first time last week at Stennis Space Center. The agency has often provided a livestream of its engine tests at Stennis, but it didn’t offer the public any live video. And this particular test was a pretty big deal. L3Harris, which acquired Aerojet Rocketdyne in 2023, has finally reactivated the RS-25 production line after a decade and billions of dollars of funding.

In fact, NASA made no public statement about the RS-25 test until Monday, and the agency didn’t mention its assignment to fly on the Artemis V mission. If the Trump administration gets its way, the engine will never fly. Maybe that’s fine, but after so long with so much taxpayer investment, this is a milestone worth publicizing, if not celebrating.

L3Harris issued a press release Tuesday confirming the engine’s planned use on the fifth SLS mission. The engine completed a 500-second acceptance test, throttling up to 111 percent of rated thrust, demonstrating more power than engines that flew on the space shuttle or on the first SLS launch in 2022.

“This successful acceptance test shows that we’ve been able to replicate the RS-25’s performance and reliability, while incorporating modern manufacturing techniques and upgraded components such as the main combustion chamber, nozzle, and pogo accumulator assembly,” said Kristin Houston, president of space propulsion and power systems at Aerojet Rocketdyne, L3Harris. “Our propulsion technology is key to ensuring the United States leads in lunar exploration, creates a sustained presence on the Moon and does not cede this strategic frontier to other nations.”

The test-firing last Friday came a few days before the 50th anniversary of the first space shuttle main engine test at Stennis on June 24, 1975. That engine carried the serial number 0001. The new RS-25 engine is designated No. 20001.

Watch out

NASA followed last week’s low-key engine test with the test-firing of a solid-fueled booster at Northrop Grumman’s rocket test site in Promontory, Utah, on Thursday. Held in place on its side, the booster produced 3.9 million pounds of thrust, outclassing the power output of the existing boosters assigned to the first eight SLS missions.

Unlike the RS-25 firing at Stennis, NASA chose to broadcast the booster test. Everything appeared to go well until 1 minute and 40 seconds into the burn, when a fiery plume of super-hot exhaust appeared to burn through part of the booster’s structure just above the nozzle. Moments later, the nozzle disintegrated.

Solid rocket boosters can’t be turned off after ignition, and for better or worse, the motor continued firing until it ran out of propellant about 30 seconds later. The rocket sparked a fire in the hills overlooking the test stand.

This was the first test-firing of the Booster Obsolescence and Life Extension (BOLE) program, which aims to develop a higher-performance solid rocket booster for SLS missions. NASA awarded Northrop Grumman a $3.2 billion contract in 2021 to produce boosters with existing shuttle parts for five SLS missions (Artemis IV-VIII), and design, develop, and test a new booster design for Artemis IX.

The boosters produce more than 75 percent of the thrust required to propel the SLS rocket off the launch pad with NASA’s crewed Orion spacecraft on top. Four RS-25 engines power the core stage, collectively generating more than 2 million pounds of thrust.

Northrop Grumman calls the new booster “the largest and most powerful segmented solid rocket motor ever built for human spaceflight.”

One of the most significant changes with the BOLE booster design is that it replaces shuttle-era steel cases with carbon-fiber composite cases. Northrop says the new cases are lighter and stronger. It also replaces the booster’s hydraulic thrust vector control steering system with an electronic system. The propellant packed inside the booster is also different, using a mix that Northrop packs inside its commercial rocket motors instead of the recipe used for the space shuttle.

Northrop Grumman has had a tough time with rocket nozzles in recent years. In 2019, a test motor for the company’s now-canceled Omega rocket lost its nozzle during a test-firing in Utah. Then, last year, a smaller Northrop-made booster flying on United Launch Alliance’s Vulcan rocket lost its nozzle in flight. Vulcan’s guidance system and main engines corrected for the problem, and the rocket still achieved its planned orbit.

During a town hall Wednesday, NASA officials on stage looked like hostages

The four people at the helm of America’s space agency held a town hall meeting with employees Wednesday, fielding questions about downsizing, layoffs, and proposed budget cuts that threaten to undermine NASA’s mission and prestige.

Janet Petro, NASA’s acting administrator, addressed questions from an auditorium at NASA Headquarters in Washington, DC. She was joined by Brian Hughes, the agency’s chief of staff, a political appointee who was formerly a Florida-based consultant active in city politics and in Donald Trump’s 2024 presidential campaign. Two other senior career managers, Vanessa Wyche and Casey Swails, were also on the stage.

They tried to put a positive spin on the situation at NASA. Petro, Wyche, and Swails are civil servants, not Trump loyalists. None of them looked like they wanted to be there. The town hall was not publicized outside of NASA ahead of time, but live video of the event was available—unadvertised—on an obscure NASA streaming website. The video has since been removed.

8 percent down

NASA’s employees are feeling the pain after the White House proposed a budget cut of nearly 25 percent in fiscal year 2026, which begins October 1. The budget request would slash NASA’s topline budget by nearly 25 percent, from $24.8 billion to $18.8 billion. Adjusted for inflation, this would be the smallest NASA budget since 1961, when the first American launched into space.

“The NASA brand is really strong still, and we have a lot of exciting missions ahead of us,” Petro said. “So, I know it’s a hard time that we’re going to be navigating, but again, you have my commitment that I’m here and I will share all of the information that I have when I get it.”

It’s true that NASA employees, along with industry officials and scientists who regularly work with the agency, are navigating through what would most generously be described as a period of great uncertainty. The perception among NASA’s workforce is far darker. “NASA is f—ed,” one current leader in the agency told Ars a few weeks ago, soon after President Trump rescinded his nomination of billionaire businessman and commercial astronaut Jared Isaacman to be the agency’s next administrator.

Before the White House released its detailed budget proposal in May, NASA and other federal agencies were already scrambling to respond to the Trump administration’s directives to shrink the size of the government. While NASA escaped the mass layoffs of probationary employees that affected other departments, the space agency offered buyouts and incentives for civil servants to retire early or voluntarily leave their posts.

About 900 NASA employees signed up for the first round of the government’s “deferred resignation” program. Casey Swails, NASA’s deputy associate administrator, said Wednesday that number is now up to 1,500 after NASA announced another chance for employees to take the government’s deferred resignation offer. This represents about 8 percent of NASA’s workforce, and the window for employees to apply runs until July 25.

One takeaway from Wednesday’s town hall is that at least some NASA leaders want to motivate more employees to resign voluntarily. Hughes said a “major reason” for luring workers to leave the agency is to avoid “being in a spot where we have to do the involuntary options.”

Rumors of these more significant layoffs, or reductions in force, have hung over NASA for several months. If that happens, workers may not get the incentives the government is offering today to those who leave the agency on their own. Swails said NASA isn’t currently planning any such layoff, although she left the door open for the situation to change: “We’re doing everything we can to avoid going down that path.”

Ultimately, it will depend on how many employees NASA can get to resign on their own. If it’s not enough, layoffs may still be an option.

Many questions, few answers

Nearly all of the questions employees addressed to NASA leadership Wednesday were submitted anonymously, and in writing: When might Trump nominate someone for NASA administrator to take Isaacman’s place? Will any of NASA’s 10 field centers be closed? What is NASA going to do about Trump’s budget proposal, particularly its impact on science missions?

Their responses to these questions, in order: Probably not any time soon, maybe, and nothing.

The Trump administration selected Petro, an engineer and former Army helicopter pilot, to become acting head of NASA on Inauguration Day in January. Bill Nelson, who served as a Florida senator until 2019, resigned the NASA administrator job when former President Biden left the White House.

Petro was previously director of NASA’s Kennedy Space Center since 2021, and before that, she was deputy director of the Florida spaceport for 14 years. She leapfrogged NASA’s top civil servant, associate administrator Jim Free, to become acting administrator in January. Free retired from the agency in February. Before the presidential election last year, Free advocated for the next administration to stay the course with NASA’s Artemis program.

But that’s not what the Trump administration wants to do. The White House seeks to cancel the Space Launch System rocket and Orion spacecraft, both core elements of the Artemis program to return astronauts to the Moon after two more flights. Under the new plan, NASA would procure commercial transportation to ferry crews to the Moon and Mars in a similar way to how the agency buys rides for its astronauts to the International Space Station in low-Earth orbit.

NASA’s Curiosity rover captured images to create this selfie mosaic on the surface of Mars in 2015. If implemented as written, the Trump budget proposal would mark the first time in 30 years that NASA does not have a Mars lander in development. The agency would instead turn to commercial companies to demonstrate they can deliver payloads, and eventually humans, to the red planet.

The Trump administration’s statements on space policy have emphasized the longer-term goal of human missions to Mars. The White House’s plans for what NASA will do at the Moon after the Artemis program’s first landing are still undefined.

Petro has kept a low profile since becoming NASA’s temporary chief executive five months ago. If Trump moved forward with Isaacman’s nomination, he would likely be NASA administrator today. The Senate was a few days away from confirming Isaacman when Trump pulled his nomination, apparently for political reasons. The White House withdrew the nomination the day after Elon Musk, who backed Isaacman to take the top job at NASA, left the Trump administration.

Who’s running NASA?

Now, Petro could serve out the year as NASA’s acting administrator. Petro is well-regarded at Kennedy Space Center, where she was a fixture in the center’s headquarters building for nearly 20 years. But she lacks a political constituency in the Trump administration and isn’t empowered to make major policy decisions. The budget cuts proposed for NASA came from the White House’s Office of Management and Budget, not from within the agency itself.

President Trump has the reins on the process to select the next NASA administrator. Trump named Isaacman for the office in December, more than a month before his inauguration, and the earliest any incoming president has nominated a NASA administrator. Musk had close ties to Trump then, and a human mission to Mars got a mention in Trump’s inauguration speech.

But space issues seem to have fallen far down Trump’s list of priorities. Hughes, who got his job at NASA in part due to his political connections, suggested it might be a while before Trump gets around to selecting another NASA administrator nominee.

“I think the best guess would tell you that it’s hard to imagine it happening before the next six months, and could perhaps go longer than that into the eight- or nine-month range, but that’s purely speculation,” Hughes said, foreseeing impediments such as the large number of other pending nominations for posts across the federal government and high-priority negotiations with Congress over the federal budget.

Congress is also expected to go on recess in August, so the earliest a NASA nominee might get a confirmation hearing is this fall. Then, the Senate must vote to confirm the nominee before they can take office.

The timeline of Isaacman’s nomination for NASA administrator is instructive. Trump nominated Isaacman in December, and his confirmation hearing was in April. He was on the cusp of a confirmation vote in early June when Trump withdrew his nomination on May 31.

As NASA awaits a leader with political backing, Petro said the agency is undergoing an overhaul to make it “leaner and more agile.” This is likely to result in office closures, and Hughes indicated NASA might end up shuttering entire field centers.

“To the specific question, will they be closed or consolidated? I don’t think we’re there yet to answer that question, but it is actively a part of the conversation we’re having as we go step-by-step through this,” Hughes said.

What can $4 billion buy you?

While Trump’s budget proposal includes robust funding for human space exploration, it’s a different story for most of the rest of NASA. The agency’s science budget would be cut in half to approximately $3.9 billion. NASA’s technology development division would also be reduced by 50 percent.

If the White House gets its way, NASA would scale back research on the International Space Station and cancel numerous robotic missions in development or already in space. The agency would terminate missions currently exploring Jupiter, on the way to study an asteroid, and approaching interstellar space. It would shut down the largest X-ray space telescope ever built and the only one in its class likely to be operating for the next 10 years.

“There’s a lot of science that can still be done with $4 billion,” Petro said. “How we do science, and how we do partnerships, may change in the future to sort of multiply what we’re doing.”

These partnerships might include asking academic institutions or wealthy benefactors to pitch in money to fund science projects at NASA. The agency might also invite commercial companies to play bigger roles in NASA robotic missions, which are typically owned by the government.

One employee asked what NASA could do to secure more funding in the president’s budget request. But that ship has sailed. The options now available to NASA’s leadership are to support the budget proposal, stay silent, or leave. NASA is an executive agency and part of the Trump administration, and the White House’s budget request is NASA’s, too.

“It’s not our job to advocate, but let’s try to look at this in a positive way,” Petro said. “We’ve still got a lot of money. Let’s see how much mission we can do.”

Ultimately, it’s up to Congress to appropriate funding for NASA and other parts of the government. Lawmakers haven’t signaled where they might land on NASA’s budget, but Sen. Ted Cruz (R-Texas), who is influential on space-related matters, released the text of a proposed bill a few weeks ago that would restore funding for the International Space Station and forego cancellation of the Space Launch System rocket, among other things. But Cruz did not have much to say about adding more money for NASA’s science programs.

NASA’s senior leaders acknowledged on Wednesday that the pain of the agency’s downsizing will extend far beyond its walls.

“Eighty-five percent of our budget goes out the door to contractors,” Petro said. “So, with a reduced budget, absolutely, our contractors will also be impacted. In fact, they’re probably the bigger driver that will be impacted.”

It’s clearly a turbulent time for America’s space agency, and NASA employees have another month to decide if they want to be part of it.

“I know there’s a lot to consider,” Swails said. “There’s a lot that people are thinking about. I would encourage you to talk it out. Tap into your support systems. Talk to your spouse, your partner, your friend, your financial advisor, whomever you consider those trusted advisors for you.”

This sounds like hollow advice, but it seems like it’s all NASA’s workers can do. The Trump administration isn’t waiting for Congress to finalize the budget for 2026. The downsizing is here.

after-successfully-entering-earth’s-atmosphere,-a-european-spacecraft-is-lost

After successfully entering Earth’s atmosphere, a European spacecraft is lost

exploration company, nyx, Space / /

A European company that seeks to develop orbital spacecraft for cargo, and eventually humans, took a step forward this week with a test flight that saw its “Mission Possible” vehicle power up and fly successfully in orbit before making a controlled reentry into Earth’s atmosphere.

However, after encountering an “issue,” the Exploration Company lost contact with its spacecraft a few minutes before touchdown in the ocean.

In an update on LinkedIn Tuesday morning, the company characterized the test flight as a partial success—and a partial failure.

“The capsule was launched successfully, powered the payloads nominally in-orbit, stabilized itself after separation with the launcher, re-entered and re-established communication after black out,” the company said in a statement. “We are still investigating the root causes and will share more information soon. We apologize to all our clients who entrusted us with their payloads.”

Maybe it was the parachutes

Reestablishing communications with the spacecraft after the blackout period suggests that the vehicle got through the most thermally challenging part of reentry into Earth’s atmosphere and perhaps validated the spacecraft’s handling and ability to withstand maximum heating.

Following this, according to the company’s timeline for Mission Possible, the capsule’s parachutes were due to deploy at a velocity between Mach 0.8 and Mach 0.6. The parachutes were selected for their “proven flight heritage,” the company said, and were procured from US-based Airborne Systems, which provides parachutes used by SpaceX’s Dragon, Boeing’s Starliner, and other spacecraft.

Given when the spacecraft was lost, it seems most likely that there was a problem with the deployment of the drogue or main parachutes.

Mission Possible was a 2.5-meter diameter demonstration vehicle that was among the larger payloads launched Monday afternoon on SpaceX’s Transporter 14 mission from Vandenberg Space Force Base in California. The mission sought to test four primary areas of spaceflight: structural performance in orbital flight, surviving reentry, autonomous navigation, and recovery in real-world conditions. It only clearly failed in this final task, recovering the vehicle within three days to return on-board payloads to customers.

Meeting an aggressive timeline

It is refreshing to have such clear and concise communication from a space company, especially the acknowledgment that a flight was a partial failure, within hours of launch. And it is not a surprise that there were technical challenges on a vehicle that was put together fairly rapidly and at a low cost.

tuesday-telescope:-a-new-champion-enters-the-ring

Tuesday Telescope: A new champion enters the ring

Space, tuesday telescope, Vera Rubin / /

Welcome to the Tuesday Telescope. There is a little too much darkness in this world and not enough light—a little too much pseudoscience and not enough science. We’ll let other publications offer you a daily horoscope. At Ars Technica, we’ll take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder.

After a decade of construction, a large new reflecting telescope publicly released its first images on Monday, and they are nothing short of spectacular.

The Vera C. Rubin Observatory’s primary mirror is 8.4 meters in diameter, which makes it one of the largest optical telescopes in the world. However, the real secret sauce of the telescope is its camera—the automobile-sized Legacy Survey of Space and Time camera—which has a resolution of 3,200 megapixels. Which is rather a lot.

The observatory is on a remote 2,682-meter-high (8,799 ft) mountain in northern Chile, a region of the planet with some of the best atmospheric “seeing” conditions.

The main goal of the telescope is to scan the entire Southern Hemisphere sky by taking 1,000 high-definition photographs every three nights for the next 10 years. The idea is that, assembled end to end, the observatory will provide a high-definition, four-dimensional film of the Universe changing over a decade. It will seek to encompass everything from nearby asteroids and comets to distant supernovae.

Who was Vera Rubin? She was an American astronomer who was the first person to establish the presence of dark matter in galaxies. The observatory named in her honor was funded by the US Department of Energy and the US National Science Foundation. International partners, including the French National Centre for Scientific Research, will help to store the 20 terabytes of data collected every night.

The only bummer about Monday’s announcement is the fact that it was funded by the Department of Energy and the National Science Foundation. The Trump administration has sought to halve the science budgets of both agencies in the coming years. And the prospect of losing that funding, juxtaposed against the phenomenal start of the Vera C. Rubin Observatory, reminds us of what we stand to lose if we slash basic science funding in this country.

Psyche keeps its date with an asteroid, but now it’s running in backup mode

asteroid, jet propulsion laboratory, Maxar, NASA, psyche, Science, solar system, Space, valves / /

The spacecraft, built by Maxar Space Systems, will operate its electric thrusters for the equivalent of three months between now and November to keep the mission on track for arrival at asteroid Psyche in 2029.

“Through comprehensive testing and analysis, the team narrowed down the potential causes to a valve that may have malfunctioned in the primary line,” NASA said in a statement Friday. “The switch to the identical backup propellant line in late May restored full functionality to the propulsion system.”

The next waypoint on Psyche’s voyage will be a flyby of Mars in May 2026. Officials expect Psyche to keep that date, which is critical for using Mars’ gravity to slingshot the spacecraft deeper into the Solar System, eventually reaching the asteroid belt about four years from now.

At Psyche, the spacecraft will enter orbit and progressively move closer to the asteroid, using a suite of sensors to map its surface, measure its shape, mass, and gravity field, and determine its elemental composition. Observations through telescopes suggest Psyche is roughly 140 miles (226 kilometers) in diameter, or about the width of Massachusetts. But it’s likely not spherical in shape. Scientists describe its shape as more akin to a potato.

Potatoes come in lots of shapes, and researchers won’t know exactly what Psyche looks like until NASA’s asteroid explorer arrives in 2029. Psyche will be the first metallic, or M-type, asteroid visited by any spacecraft, and scientists are eager to study an object that’s largely made of metals—probably iron, nickel, and perhaps some rarer elements— instead of rocky minerals.

With the Psyche spacecraft’s plasma thrusters back in action, these goals of NASA’s billion-dollar science mission remain achievable.

“The mission team’s dedication and systematic approach to this investigation exemplifies the best of NASA engineering,” said Bob Mase, Psyche project manager at  JPL, in a statement. “Their thorough diagnosis and recovery, using the backup system, demonstrates the value of robust spacecraft design and exceptional teamwork.”

But there’s still a lingering concern whatever problem caused the valve to malfunction in the primary fuel line might also eventually affect the same kind of valve in the backup line.

“We are doing a lot of good proactive work around that possible issue,” wrote Lindy Elkins-Tanton, Psyche’s principal investigator at Arizona State University, in a post on X.

Welcome to Edition 7.49 of the Rocket Report! You may have noticed we are a little late with the report this week, and that is due to the Juneteenth holiday celebrated in the United States on Thursday. But that hasn’t stopped a torrent of big news this week, from exploding Starships to significant reuse milestones being reached in Asia.

As always, we welcome reader submissions, and if you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Honda stamps passport to the skies with a hopper. An experimental reusable rocket developed by the research and development arm of Honda Motor Company flew to an altitude of nearly 900 feet (275 meters) Tuesday, then landed with pinpoint precision at the carmaker’s test facility in northern Japan, Ars reports. Honda’s hopper is the first prototype rocket outside of the United States and China to complete a flight of this kind, demonstrating vertical takeoff and vertical landing technology that could underpin the development of a reusable launch vehicle.

A legitimately impressive feat… Honda has been quiet on this rocket project since a brief media blitz nearly four years ago. Developed in-house by Honda R&D Company, the rocket climbed vertically from a pedestal at the company’s test site in southeastern Hokkaido, the northernmost of Japan’s main islands, before landing less than a meter from its target. Honda said its launch vehicle is “still in the fundamental research phase,” and the company has made no decision whether to commercialize the rocket program.

European launch companies seek protection. In a joint statement published on Monday, Arianespace and Avio called for European missions to be launched aboard European rockets, European Spaceflight reports. The statement warned that without “sustained support,” European rocket builders risked losing out to institutionally backed competitors from the US.

Seeking to permanently embed European preference… “Major space powers support their industries through stable and guaranteed institutional markets, enabling long-term investments, innovation, and the preservation of leadership,” explained the statement. The pair argues that Europe risks falling behind not due to a lack of technical capability but because of structural market weaknesses. (submitted by EllPeaTea)

Increasing launch cadence may threaten ozone layer. The rapidly growing number of rocket launches could slow the recovery of the ozone layer, a new study in the journal Nature finds. The ozone layer is healing due to countries phasing out CFCs, but rocket launches could slow its recovery if the space industry continues growing, Radio New Zealand reports. “At the moment, it’s not a problem because the launches happen too infrequently,” said University of Canterbury atmospheric scientist Laura Revell, one of the authors of the study. “As we get more and more launches taking place—because there are companies out there with very bold ambitions to increase launch frequency—this is potentially going to be a problem.”

Forecasting a lot of growth in launch… In a conservative growth scenario, about 900 total launches a year, there is some ozone loss but not significant amounts,” said Revell. “But when we look at a more ambitious scenario, when we looked at the upper limits of what might be launched in future—around 2,000 launches year—we saw levels of ozone loss that are concerning in the context of ozone recovery,” she said. Ozone losses are driven by the chlorine produced from solid rocket motor propellant and black carbon, which is emitted from most propellants, the study says. (submitted by Zaphod Harkonnen)

Space may soon be pay-to-play with the FAA. The Federal Aviation Administration may soon levy fees on companies seeking launch and reentry licenses, a new tack in the push to give the agency the resources it needs to keep up with the rapidly growing commercial space industry, Ars reports. The text of a budget reconciliation bill released by Sen. Ted Cruz (R-Texas) earlier this month calls for the FAA’s Office of Commercial Space Transportation, known as AST, to begin charging licensing fees to space companies next year.

The price of poker keeps going up… The fees would phase in over eight years, after which the FAA would adjust them to keep pace with inflation. The money would go into a trust fund to help pay for the operating costs of the FAA’s commercial space office. Cruz’s section of the Senate reconciliation bill calls for the FAA to charge commercial space companies per pound of payload mass, beginning with 25 cents per pound in 2026 and increasing to $1.50 per pound in 2033. Subsequent fee rates would change based on inflation. The overall fee per launch or entry would be capped at $30,000 in 2026, increasing to $200,000 in 2033, and then be adjusted to keep pace with inflation.

Landspace tests Zhuque-3 rocket. Chinese launch startup Landspace carried out a breakthrough static fire test Friday as it builds towards an orbital launch attempt with its Zhuque-3 rocket, Space News reports. The Zhuque-3’s nine methane-liquid oxygen engines ignited in sequence and fired for 45 seconds, including gimbal control testing, before shutting down as planned. The successful test lays a solid foundation for the upcoming inaugural flight of the Zhuque-3 and for the country’s reusable launch vehicle technology, Landspace said.

Similar in design to Falcon 9 … Friday’s static fire test used a first-stage identical to the one intended for Zhuque-3’s inaugural flight, planned for later this year, and covered the full ground-based launch preparation and ignition sequence, including propellant loading, tank pressurization, staged engine ignition, steady-state operation and a programmed shutdown. Payload capacity to low Earth orbit will be 21 metric tons when expendable, or up to 18,300 kg when the first stage is recovered downrange. Alternatively, it can carry 12,500 kg to LEO when returning to the launch site.

Kuiper launch scrubs due to hardware issue. United Launch Alliance and its customer, Amazon, will have to wait longer for the second launch of Amazon’s Project Kuiper satellites following a scrub on Monday afternoon. “United Launch Alliance Atlas 5 551 carrying Amazon’s second Project Kuiper mission, Kuiper 2, is delayed due to an engineering observation of an elevated purge temperature within the booster engine,” ULA said in a statement. “The team will evaluate the hardware, and we will release a new launch date when available.”

Back to the VIF in a spiff… On Tuesday, ULA rolled the Atlas V rocket back to its Vertical Integration Facility to address the issue with the nitrogen purge line on the vehicle. In addition to this mission, ULA has six more Atlas 5 rockets that have been purchased by Amazon to fly satellites for its constellation. As of Friday morning, ULA had not set a new launch date for the Kuiper 2 mission, but it could take place early next week. (submitted by ElllPeaTea)

Varda’s next launch will use in-house spacecraft. Varda Space Industries is preparing to launch its fourth spacecraft, W-4, on a SpaceX rideshare mission scheduled to launch as soon as June 21 from Vandenberg Space Force Base in California, Space News reports. The Los Angeles-based startup manufactures pharmaceuticals in orbit and returns them to Earth using specialized reentry capsules.

No longer using Rocket Lab… For its first three missions, Varda had partnered with Rocket Lab to use its Photon spacecraft for in-space operations. However, with W-4, Varda is debuting its first spacecraft built entirely in-house. The company is consolidating design and production internally in an effort to shorten the timeline between missions and increase flexibility to tailor vehicles to customer requirements. Varda decided that vertical integration was essential for scaling operations. (submitted by MarkW98)

Vandenberg becomes SpaceX west. One of the defining events early in the history of SpaceX is when the company was effectively booted from Vandenberg Space Force Base in 2005 after completing the first successful test firing of the Falcon 1 rocket there. This set the company off on a long romp to Kwajalein Atoll in the Pacific Ocean before acquiring a launch site at Cape Canaveral, Florida. When SpaceX finally returned to Vandenberg half a decade later, it had the Falcon 9 rocket and was no longer the scrappy upstart. Since then, it has made Vandenberg its own.

Falcons flying frequently… According to Spaceflight Now, on Monday, SpaceX launched the 200th overall orbital flight from Space Launch Complex 4 East at Vandenberg Space Force Base, a batch of 26 Starlink V2 Mini satellites. Among the 199 previous orbital launches from SLC-4E, 131 of them were Falcon 9 rockets. The pad was first occupied by the Atlas-Agena rocket shortly after the Air Force Western Test Range activated in May 1964. SpaceX is currently going through the review process for acquiring SLC-6 as well to use for its Falcon 9 and Falcon Heavy rockets. (submitted by EllPeaTea)

China tests launch abort system. China carried out a successful pad abort test early Tuesday for its next-generation crew spacecraft for moon and low-Earth orbit missions, Space News reports. Footage of the test shows the escape system rapidly boosting the Mengzhou spacecraft away from the ground. Around 20 seconds later, the vehicle reached a predetermined altitude. The return capsule separated from the escape tower, and its parachutes deployed successfully. China is planning to conduct an in-flight escape test at maximum dynamic pressure later this year.

No longer reliant on the rocket… According to the agency, Mengzhou shifts from the traditional model of “rocket handles abort, spacecraft handles crew rescue,” as used by the Shenzhou, to a system where the Mengzhou spacecraft takes full responsibility for both abort control and crew safety. “The success of this test lays an important technical foundation for future crewed lunar missions,” a Chinese statement read. “Development work on related spacecraft, such as the Long March 10 launch vehicle and the lunar lander, is progressing steadily and will proceed to further testing as scheduled.” (submitted by EllPeaTea)

Another Starship explodes unexpectedly. SpaceX’s next Starship rocket exploded during a ground test in South Texas late Wednesday, dealing another blow to a program already struggling to overcome three consecutive failures in recent months, Ars reports. The late-night explosion at SpaceX’s rocket development complex in Starbase, Texas, destroyed the upper stage that was slated to launch on the next Starship test flight. The powerful blast set off fires around SpaceX’s Massey’s Test Site, located a few miles from the company’s Starship factory and launch pads.

A major anomaly … SpaceX confirmed the Starship, numbered Ship 36 in the company’s inventory, “experienced a major anomaly” on a test stand as the vehicle prepared to ignite its six Raptor engines for a static fire test. These hold-down test-firings are typically one of the final milestones in a Starship launch campaign before SpaceX moves the rocket to the launch pad. The company later said the failure may have been due to a composite overwrap pressure vessel, or COPV, near the top of the vehicle. On Thursday, aerial videos revealed that damage at the test site was significant but not beyond repair. (submitted by Tfargo04)

ArianeGroup will lead reusable engine project. The French space agency CNES announced Tuesday that it had selected ArianeGroup to lead a project to develop a high-thrust reusable rocket engine, European Spaceflight reports. The ASTRE (Advanced Staged-Combustion Technologies for Reusable Engines) project will also include contributions from SiriusSpace and Pangea Aerospace.

Company will take a test and learn approach… The project aims to develop a full-flow staged combustion methalox reusable rocket engine capable of producing between 200 and 300 tonnes of thrust, placing it in roughly the same class as the SpaceX Raptor engine. According to the agency, the goal of the project is “to equip the French and European space industry with new capabilities for strategic applications.” (submitted by EllPeaTea)

SpaceX’s next Starship rocket exploded during a ground test in South Texas late Wednesday, dealing another blow to a program already struggling to overcome three consecutive failures in recent months.

The late-night explosion at SpaceX’s rocket development complex in Starbase, Texas, destroyed the bullet-shaped upper stage that was slated to launch on the next Starship test flight. The powerful blast set off fires around SpaceX’s Massey’s Test Site, located a few miles from the company’s Starship factory and launch pads.

Live streaming video from NASASpaceflight.com and LabPadre—media organizations with cameras positioned around Starbase—showed the 15-story-tall rocket burst into flames shortly after 11: 00 pm local time (12: 00 am EDT; 04: 00 UTC). Local residents as far as 30 miles away reported seeing and feeling the blast.

SpaceX confirmed the Starship, numbered Ship 36 in the company’s inventory, “experienced a major anomaly” on a test stand as the vehicle prepared to ignite its six Raptor engines for a static fire test. These hold-down test-firings are typically one of the final milestones in a Starship launch campaign before SpaceX moves the rocket to the launch pad.

The explosion occurred as SpaceX finished up loading super-cold methane and liquid oxygen propellants into Starship in preparation for the static fire test. The company said the area around the test site was evacuated of all personnel, and everyone was safe and accounted for after the incident. Firefighters from the Brownsville Fire Department were dispatched to the scene.

“Our Starbase team is actively working to safe the test site and the immediate surrounding area in conjunction with local officials,” SpaceX posted on X. “There are no hazards to residents in surrounding communities, and we ask that individuals do not attempt to approach the area while safing operations continue.”

Picking up the pieces

Earlier Wednesday, just hours before the late-night explosion at Starbase, an advisory released by the Federal Aviation Administration showed SpaceX had set June 29 as a tentative launch date for the next Starship test flight. That won’t happen now, and it’s anyone’s guess when SpaceX will have another Starship ready to fly.

Massey’s Test Site, named for a gun range that once occupied the property, is situated on a bend in the Rio Grande River, just a few hundred feet from the Mexican border. The test site is currently the only place where SpaceX can put Starships through proof testing and static fire tests before declaring the rockets are ready to fly.

The extent of the damage to ground equipment at Massey’s was not immediately clear, so it’s too soon to say how long the test site will be out of commission. For now, though, the explosion leaves SpaceX without a facility to support preflight testing on Starships.

The videos embedded below come from NASASpaceflight.com and LabPadre, showing multiple angles of the Starship blast.

The explosion at Massey’s is a reminder of SpaceX’s rocky path to get Starship to this point in its development. In 2020 and 2021, SpaceX lost several Starship prototypes to problems during ground and flight testing. The visual of Ship 36 going up in flames harkens back to those previous explosions, along with the fiery demise of a Falcon 9 rocket on its launch pad in 2016 under circumstances similar to Wednesday night’s incident.

SpaceX has now launched nine full-scale Starship rockets since April 2023, and before the explosion, the company hoped to launch the 10th test flight later this month. Starship’s track record has been dreadful so far this year, with the rocket’s three most recent test flights ending prematurely. These setbacks followed a triumphant 2024, when SpaceX made clear progress on each successive Starship suborbital test flight, culminating in the first catch of the rocket’s massive Super Heavy booster with giant robotic arms on the launch pad tower.

Stacked together, the Super Heavy booster stage and Starship upper stage stand more than 400 feet tall, creating the largest rocket ever built. SpaceX has already flown a reused Super Heavy booster, and the company has designed Starship itself to be recoverable and reusable, too.

After last year’s accomplishments, SpaceX appeared to be on track for a full orbital flight, an attempt to catch and recover Starship itself, and an important in-space refueling demonstration in 2025. The refueling demo has officially slipped into 2026, and it’s questionable whether SpaceX will make enough progress in the coming months to attempt recovery of a ship before the end of this year.

Ambition meets reality

SpaceX debuted an upgraded Starship design, called Version 2 or Block 2, on a test flight in January. It’s been one setback after another since then.

The new Starship design is slightly taller than the version of Starship that SpaceX flew in 2023 and 2024. It has an improved heat shield to better withstand the extreme heat of atmospheric reentry. SpaceX also installed a new fuel feed line system to route methane fuel to the ship’s Raptor engines, and an improved propulsion avionics module controlling the vehicle’s valves and reading sensors.

Despite—or perhaps because of—all of these changes for Starship Version 2, SpaceX has been unable to replicate the successes it achieved with Starship in the last two years. Ships launched on test flights in January and March spun out of control minutes after liftoff, scattering debris over the sea, and in at least one case, onto a car in the Turks and Caicos Islands.

SpaceX engineers concluded the January failure was likely caused by intense vibrations that triggered fuel leaks and fires in the ship’s engine compartment, causing an early shutdown of the rocket’s engines. Engineers said the vibrations were likely in resonance with the vehicle’s natural frequency, intensifying the shaking beyond the levels SpaceX predicted.

The March flight failed in similar fashion, but SpaceX’s investigators determined the most probable root cause was a hardware failure in one of the ship’s engines, a different failure mode than two months before.

During SpaceX’s most recent Starship test flight last month, the rocket completed the ascent phase of the mission as planned, seemingly overcoming the problems that plagued the prior two launches. But soon after the Raptor engines shut down, a fuel leak caused the ship to begin tumbling in space, preventing the vehicle from completing a guided reentry to test the performance of new heat shield materials.

SpaceX is working on a third-generation Starship design, called Version 3, that the company says could be ready to fly by the end of this year. The upgraded Starship Version 3 design will be able to lift heavier cargo—up to 200 metric tons—into orbit thanks to larger propellant tanks and more powerful Raptor engines. Version 3 will also have the ability to refuel in low-Earth orbit.

Version 3 will presumably have permanent fixes to the problems currently slowing SpaceX’s pace of Starship development. And there are myriad issues for SpaceX’s engineers to solve, from engine reliability and the ship’s resonant frequency, to beefing up the ship’s heat shield and fixing its balky payload bay door.

Once officials solve these problems, it will be time for SpaceX to bring a Starship from low-Earth orbit back to the ground. Then, there’s more cool stuff on the books, like orbital refueling and missions to the Moon in partnership with NASA’s Artemis program. NASA has contracts worth more than $4 billion with SpaceX to develop a human-rated Starship that can land astronauts on the Moon and launch them safely back into space.

The Trump administration’s proposed budget for NASA would cancel the Artemis program’s ultra-expensive Space Launch System rocket and Orion crew capsule after two more flights, leaving commercial heavy-lifters to take over launching astronauts from the Earth to the Moon. SpaceX’s Starship, already on contract with NASA as a human-rated lander, may eventually win more government contracts to fill the role of SLS and Orion under Trump’s proposed budget. Other rockets, such as Blue Origin’s New Glenn, are also well-positioned to play a larger role in human space exploration.

NASA’s official schedule for the first Artemis crew landing on the Moon puts the mission some time in 2027, using SLS and Orion to transport astronauts out to the vicinity of the Moon to meet up with SpaceX’s Starship lunar lander. After that mission, known as Artemis III, NASA would pivot to using commercial rockets from Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin to replace the Space Launch System.

Meanwhile, SpaceX’s founder and CEO has his sights set on Mars. Last month, Musk told his employees he wants to launch the first Starships toward the Red Planet in late 2026, when the positions of Earth and Mars in the Solar System make a direct journey possible. Optimistically, he would like to send people to Mars on Starships beginning in 2028.

All of these missions are predicated on SpaceX mastering routine Starship launch operations, rapid reuse of the ship and booster, and cryogenic refueling in orbit, along with adapting systems such as life support, communications, and deep space navigation for an interplanetary journey.

The to-do list is long for SpaceX’s Starship program—too long for Mars landings to seem realistic any time in the next few years. NASA’s schedule for the Artemis III lunar landing mission in 2027 is also tight, and not only because of Starship’s delays. The development of new spacesuits for astronauts to wear on the Moon may also put the Artemis III schedule at risk. NASA’s SLS rocket and Orion spacecraft have had significant delays throughout their history, so it’s not a sure thing they will be ready in 2027.

While it’s too soon to know the precise impact of Wednesday night’s explosion, we can say with some confidence that the chances of Starship meeting these audacious schedules are lower today than they were yesterday.

Honda’s hopper suddenly makes the Japanese carmaker a serious player in rocketry

honda, Japan, launch, rocket, Science, Space / /

The company has not disclosed its spending on rocket development. Honda’s hopper is smaller than similar prototype boosters SpaceX has used for vertical landing demos, so engineers will have to scale up the design to create a viable launch vehicle.

But Tuesday’s test catapulted Honda into an exclusive club of companies that have flown reusable rocket hoppers with an eye toward orbital flight, including SpaceX, Blue Origin, and a handful of Chinese startups. Meanwhile, European and Japanese space agencies have funded a pair of reusable rocket hoppers named Themis and Callisto. Neither rocket has ever flown, after delays of several years.

Honda’s experimental rocket lifts off from a test site in Taiki, a community in northern Japan.

Before Honda’s leadership green-lit the rocket project in 2019, a group of the company’s younger engineers proposed applying the company’s expertise in combustion and control technologies toward a launch vehicle. Honda officials believe the carmaker “has the potential to contribute more to people’s daily lives by launching satellites with its own rockets.”

The company suggested in its press release Tuesday that a Honda-built rocket might launch Earth observation satellites to monitor global warming and extreme weather, and satellite constellations for wide-area communications. Specifically, the company noted the importance of satellite communications to enabling connected features in cars, airplanes, and other Honda products.

“In this market environment, Honda has chosen to take on the technological challenge of developing reusable rockets by utilizing Honda technologies amassed in the development of various products and automated driving systems, based on a belief that reusable rockets will contribute to achieving sustainable transportation,” Honda said.

Toyota, Japan’s largest car company, also has a stake in the launch business. Interstellar Technologies, a Japanese space startup, announced a $44 million investment from Toyota in January. The two firms said they were establishing an alliance to draw on Toyota’s formula for automobile manufacturing to set up a factory for mass-producing orbital-class rockets. Interstellar has launched a handful of sounding rockets but hasn’t yet built an orbital launcher.

Japan’s primary rocket builder, Mitsubishi Heavy Industries, is another titan of Japanese industry, but it has never launched more than six space missions in a single year. MHI’s newest rocket, the H3, debuted in 2023 but is fully expendable.

The second-biggest Japanese automaker, Honda, is now making its own play. Car companies aren’t accustomed to making vehicles that can only be used once.

Companies may soon pay a fee for their rockets to share the skies with airplanes

FAA, federal budget, Space, ted cruz / /

The Federal Aviation Administration may soon levy fees on companies seeking launch and reentry licenses, a new tack in the push to give the agency the resources it needs to keep up with the rapidly growing commercial space industry.

The text of a budget reconciliation bill released by Sen. Ted Cruz (R-Texas) last week calls for the FAA’s Office of Commercial Space Transportation, known as AST, to begin charging licensing fees to space companies next year. The fees would phase in over eight years, after which the FAA would adjust them to keep pace with inflation. The money would go into a trust fund to help pay for the operating costs of the FAA’s commercial space office.

The bill released by Cruz’s office last week covers federal agencies under the oversight of the Senate Commerce Committee, which he chairs. These agencies include the FAA and NASA. Ars recently covered Cruz’s proposals for NASA to keep the Space Launch System rocket, Orion spacecraft, and Gateway lunar space station alive, while the Trump administration aims to cancel Gateway and end the SLS and Orion programs after two crew missions to the Moon.

The Trump administration’s fiscal year 2026 budget request, released last month, proposes $42 million for the FAA’s Office of Commercial Space Transportation, a fraction of the agency’s overall budget request of $22 billion. The FAA’s commercial space office received an almost identical funding level in 2024 and 2025. Accounting for inflation, this is effectively a budget cut for AST. The office’s budget increased from $27.6 million to more than $42 million between 2021 and 2024, when companies like SpaceX began complaining the FAA was not equipped to keep up with the fast-moving commercial launch industry.

The FAA licensed 11 commercial launch and reentry operations in 2015, when AST’s budget was $16.6 million. Last year, the number of space operations increased to 164, and the US industry is on track to conduct more than 200 commercial launches and reentries in 2025. SpaceX’s Falcon 9 rocket is doing most of these launches.

While the FAA’s commercial space office receives more federal funding today, the budget hasn’t grown to keep up with the cadence of commercial spaceflight. SpaceX officials urged the FAA to double its licensing staff in 2023 after the company experienced delays in securing launch licenses.

In the background, a Falcon 9 rocket climbs away from Space Launch Complex 40 at Cape Canaveral Space Force Station, Florida. Another Falcon 9 stands on its launch pad at neighboring Kennedy Space Center awaiting its opportunity to fly.

Adding it up

Cruz’s section of the Senate reconciliation bill calls for the FAA to charge commercial space companies per pound of payload mass, beginning with 25 cents per pound in 2026 and increasing to $1.50 per pound in 2033. Subsequent fee rates would change based on inflation. The overall fee per launch or entry would be capped at $30,000 in 2026, increasing to $200,000 in 2033, and then adjusted to keep pace with inflation.

The Trump administration has not weighed in on Cruz’s proposed fee schedule, but Trump’s nominee for the next FAA administrator, Bryan Bedford, agreed with the need for launch and reentry licensing fees in a Senate confirmation hearing Wednesday. Most of the hearing’s question-and-answer session focused on the safety of commercial air travel, but there was a notable exchange on the topic of commercial spaceflight.

Cruz said the rising number of space launches will “add considerable strain to the airspace system” in the United States. Airlines and their passengers pay FAA-mandated fees for each flight segment, and private owners pay the FAA a fee to register their aircraft. The FAA also charges overflight fees to aircraft traveling through US airspace, even if they don’t take off or land in the United States.

“Nearly every user of the National Airspace System pays something back into the system to help cover their operational costs, yet under current law, space launch companies do not, and there is no mechanism for them to pay even if they wish to,” Cruz said. “As commercial spaceflight expands rapidly, so does its impact on the FAA’s ability to operate the National Airspace System. This proposal accounts for that.”

When asked if he agreed, Trump’s FAA nominee suggested he did. Bedford, president and CEO of Republic Airways, is poised to take the helm of the federal aviation regulator if he passes Senate confirmation.

The FAA clears airspace of commercial and private air traffic along the flight corridors of rockets as they launch into space, and around the paths of spacecraft as they return to Earth. The agency is primarily charged with ensuring commercial rockets don’t endanger the public. The National Airspace System (NAS) consists of 29 million square miles of airspace over land and oceans. The FAA says more than 45,000 flights and 2.9 million airline passengers travel through the airspace every day.

Bedford said he didn’t want to speak on specific policy proposals before the Trump administration announces an official position on the matter.

“But I’ll confirm you’re exactly right,” Bedford told Cruz. “Passengers and airlines themselves pay significant taxes. … Those taxes are designed to modernize our NAS. One of the things that is absolutely critical in modernization is making sure we design the NAS so it can accommodate an increased cadence in space launch, so I certainly support where you’re going with that.”

SpaceX would be the company most affected by the proposed licensing fees. The majority of SpaceX’s missions launch the company’s own Starlink broadband satellites aboard Falcon 9 rockets. Most of those launches carry around 17 metric tons (about 37,500 pounds) of usable payload mass.

A quick calculation shows that SpaceX would pay a fee of roughly $9,400 for an average Starlink launch on a Falcon 9 rocket next year if Cruz’s legislation is signed into law. SpaceX launched 89 dedicated Starlink missions last year. That would add up to more than $800,000 in annual fees going into the FAA’s coffers under Cruz’s licensing scheme. Once you account for all of SpaceX’s other commercial launches, this number would likely exceed $1 million.

Assuming Falcon 9s continue to launch Starlink satellites in 2033, the fees would rise to approximately $56,000 per launch. SpaceX may have switched over all Starlink missions to its giant new Starship rocket by then, in which case the company will likely reach the FAA’s proposed fee cap of $200,000 per launch. SpaceX hopes to launch Starships at lower cost than it currently launches the Falcon 9 rocket, so this proposal would see SpaceX pay a significantly larger fraction of its per-mission costs in the form of FAA fees.

Industry reaction

A senior transportation official in the Biden administration voiced tentative support in 2023 for a fee scheme similar to the one under consideration by the Senate. Michael Huerta, a former FAA administrator during the Obama administration and the first Trump administration, told NPR last year that he supports the idea.

“You have this group of new users that are paying nothing into the system that are an increasing share of the operations,” Huerta said. “I truly believe the current structure isn’t sustainable.”

The Commercial Spaceflight Federation, an industry advocacy group that includes SpaceX and Blue Origin among its membership, signaled last year it was against the idea of creating launch and reentry fees, or taxes, as some industry officials call them. Commercial launch and reentry companies have been excluded from FAA fees to remove regulatory burdens and help the industry grow. The federation told NPR last year that because the commercial space industry requires access to US airspace much less often than the aviation industry, it would not yet be appropriate to have space companies pay into an FAA trust fund.

SpaceX did not respond to questions from Ars on the matter. United Launch Alliance would likely be on the hook to become the second-largest payer of FAA fees, at least over the next couple of years, with numerous missions in its backlog to launch massive stacks of Internet satellites for Amazon’s Project Kuiper network from Cape Canaveral Space Force Station in Florida.

A ULA spokesperson told Ars the company is still reviewing and assessing the Senate Commerce Committee’s proposal. “In general, we are supportive of fees that are affordable, do not disadvantage US companies against their foreign counterparts, are fair, equitable, and are used to directly improve the shared infrastructure at the Cape and other spaceports,” the spokesperson said.
