Welcome to Edition 7.35 of the Rocket Report! SpaceX’s steamroller is still rolling, but for the first time in many years, it doesn’t seem like it’s rolling downhill. After a three-year run of perfect performance—with no launch failures or any other serious malfunctions—SpaceX’s Falcon 9 rocket has suffered a handful of issues in recent months. Meanwhile, SpaceX’s next-generation Starship rocket is having problems, too. Kiko Dontchev, SpaceX’s vice president of launch, addressed some (but not all) of these concerns in a post on X this week. Despite the issues with the Falcon 9, SpaceX has maintained a remarkable launch cadence. As of Thursday, SpaceX has launched 28 Falcon 9 flights since January 1, ahead of last year’s pace.

Alpha rocket preps for weekend launch. While Firefly Aerospace is making headlines for landing on the Moon, its Alpha rocket is set to launch again as soon as Saturday morning from Vandenberg Space Force Base, California. The two-stage, kerosene-fueled rocket will launch a self-funded technology demonstration satellite for Lockheed Martin. It’s the first of up to 25 launches Lockheed Martin has booked with Firefly over the next five years. This launch will be the sixth flight of an Alpha rocket, which has become a leader in the US commercial launch industry for dedicated missions with 1 ton-class satellites.

Firefly’s OG … The Alpha rocket was Firefly’s first product, and it has been a central piece of the company’s development since 2014. Like Firefly itself, the Alpha rocket program has gone through multiple iterations, including a wholesale redesign nearly a decade ago. Sure, Firefly can’t claim any revolutionary firsts with the Alpha rocket, as it can with its Blue Ghost lunar lander. But without Alpha, Firefly wouldn’t be where it is today. The Texas-based firm is one of only four US companies with an operational orbital-class rocket. One thing to watch for is how quickly Firefly can ramp up its Alpha launch cadence. The rocket only flew once last year.

Isar Aerospace celebrates another win. In last week’s Rocket Report, we mentioned that the German launch startup Isar Aerospace won a contract with a Japanese company to launch a 200-kilogram commercial satellite in 2026. But wait, there’s more! On Wednesday, the Norwegian Space Agency announced it awarded a contract to Isar Aerospace for the launch of a pair of satellites for the country’s Arctic Ocean Surveillance initiative, European Spaceflight reports. The satellites are scheduled to launch on Isar’s Spectrum rocket from Andøya Spaceport in Norway by 2028.

First launch pending … These recent contract wins are a promising sign for Isar Aerospace, which is also vying for contracts to launch small payloads for the European Space Agency. The Spectrum rocket could launch on its inaugural flight within a matter of weeks, and if successful, it could mark a transformative moment for the European space industry, which has long been limited to a single launch provider: the French company Arianespace.

Mother Nature holds up Oz launch. The first launch by Gilmour Space has been postponed again due to a tropical cyclone that brought severe weather to Australia’s Gold Coast region earlier this month, InnovationAus.com reports. Tropical Cyclone Alfred didn’t significantly impact Gilmour’s launch site, but the storm did cause the company to suspend work at its corporate headquarters in Southeast Queensland. With the storm now over, Gilmour is reassessing when it might be ready to launch its Eris rocket. Reportedly, the delay could be as long as two weeks or more.

A regulatory storm … Gilmour aims to become the first Australian company to launch a rocket into orbit. Last month, Gilmour announced the launch date for the Eris rocket was set for no earlier than March 15, but Tropical Cyclone Alfred threw this schedule out the window. Gilmour said it received a launch license from the Australian Space Agency in November and last month secured approvals to clear airspace around the launch site. But there’s still a hitch. The license is conditional on final documentation for the launch being filed and agreed with the space agency, and this process is stretching longer than anticipated. (submitted by ZygP)

What is going on at SpaceX? As we mention in the introduction to this week’s Rocket Report, it has been an uncharacteristically messy eight months for SpaceX. These speed bumps include issues with the Falcon 9 rocket’s upper stage on three missions, two lost Falcon 9 boosters, and consecutive failures of SpaceX’s massive Starship rocket on its first two test flights of the year. So what’s behind SpaceX’s bumpy ride? Ars wrote about the pressures facing SpaceX employees as Elon Musk pushes his workforce ever-harder to accelerate toward what Musk might call a multi-planetary future.

Headwinds or tailwinds? … No country or private company ever launched as many times as SpaceX flew its fleet of Falcon 9 rockets in 2024. At the same time, the company has been attempting to move its talented engineering team off the Falcon 9 and Dragon programs and onto Starship to keep that ambitious program moving forward. This is all happening as Musk has taken on significant roles in the Trump administration, stirring controversy and raising questions about his motives and potential conflicts of interest. However, it may be not so much Musk’s absence from SpaceX that is causing these issues but more the company’s relentless culture. As my colleague Eric Berger suggested in his piece, it seems possible that, at least for now, SpaceX has reached the speed limit for commercial spaceflight.

A titan of Silicon Valley enters the rocket business. Former Google chief executive Eric Schmidt has taken a controlling interest in the Long Beach, California-based Relativity Space, Ars reports. Schmidt’s involvement with Relativity has been quietly discussed among space industry insiders for a few months. Multiple sources told Ars that he has largely been bankrolling the company since the end of October, when the company’s previous fundraising dried up. Now, Schmidt is Relativity’s CEO.

Unclear motives … It is not immediately clear why Schmidt is taking a hands-on approach at Relativity. However, it is one of the few US-based companies with a credible path toward developing a medium-lift rocket that could potentially challenge the dominance of SpaceX and its Falcon 9 rocket. If the Terran R booster becomes commercially successful, it could play a big role in launching megaconstellations. Schmidt’s ascension also means that Tim Ellis, the company’s co-founder, chief executive, and almost sole public persona for nearly a decade, is now out of a leadership position.

Falcon 9 deploys NASA’s newest space telescope. Satellites come in all shapes and sizes, but there aren’t any that look quite like SPHEREx, an infrared observatory NASA launched Tuesday night in search of answers to simmering questions about how the Universe, and ultimately life, came to be, Ars reports. The SPHEREx satellite rocketed into orbit from California aboard a SpaceX Falcon 9 rocket, beginning a two-year mission surveying the sky in search of clues about the earliest periods of cosmic history, when the Universe rapidly expanded and the first galaxies formed. SPHEREx will also scan for pockets of water ice within our own galaxy, where clouds of gas and dust coalesce to form stars and planets.

Excess capacity … SPHEREx has lofty goals, but it’s modest in size, weighing just a little more than a half-ton at launch. This meant the Falcon 9 rocket had plenty of extra room for four other small satellites that will fly in formation to image the solar wind as it travels from the Sun into the Solar System. The four satellites are part of NASA’s PUNCH mission. SPHEREx and PUNCH are part of NASA’s Explorers program, a series of cost-capped science missions with a lineage going back to the dawn of the Space Age. SPHEREx and PUNCH have a combined cost of about $638 million. (submitted by EllPeaTea)

China has launched another batch of Internet satellites. A new group of 18 satellites entered orbit Tuesday for the Thousand Sails constellation with the first launch from a new commercial launch pad, Space News reports. The satellites launched on top of a Long March 8 rocket from Hainan Commercial Launch Site near Wenchang on Hainan Island. The commercial launch site has two pads, the first of which entered service with a launch last year. This mission was the first to launch from the other pad at the commercial spaceport, which is gearing up for an uptick in Chinese launch activity to continue deploying satellites for the Thousand Sails network and other megaconstellations.

Sailing on … The Thousand Sails constellation, also known as Qianfan, or G60 Starlink, is a broadband satellite constellation spearheaded by Shanghai Spacecom Satellite Technology (SSST), also known as Spacesail, Space News reported. The project, which aims to deploy 14,000 satellites, seeks to compete in the global satellite Internet market. Spacesail has now launched 90 satellites into near-polar orbits, and the operator previously stated it aims to have 648 satellites in orbit by the end of 2025. If Spacesail continues launching 18 satellites per rocket, this goal would require 31 more launches this year. (submitted by EllPeaTea)

NASA, SpaceX call off astronaut launch. With the countdown within 45 minutes of launch, NASA called off an attempt to send the next crew to the International Space Station Wednesday evening to allow more time to troubleshoot a ground system hydraulics issue, CBS News reports. During the countdown Wednesday, SpaceX engineers were troubleshooting a problem with one of two clamp arms that hold the Falcon 9 rocket to its strongback support gantry. Hydraulics are used to retract the two clamps prior to launch.

Back on track … NASA confirmed Thursday SpaceX ground teams completed inspections of the hydraulics system used for the clamp arm supporting the Falcon 9 rocket and successfully flushed a suspected pocket of trapped air in the system, clearing the way for another launch attempt Friday evening. This mission, known as Crew-10, will ferry two NASA astronauts, a Japanese mission specialist, and a Russian cosmonaut to the space station. They will replace a four-person crew currently at the ISS, including Butch Wilmore and Suni Williams, who have been in orbit since last June after flying to space on Boeing’s Starliner capsule. Starliner returned to Earth without its crew due to a problem with overheating thrusters, leaving Wilmore and Williams behind to wait for a ride home with SpaceX.

SpaceX’s woes reach Poland’s space agency. The president of the Polish Space Agency, Grzegorz Wrochna, has been dismissed following a botched response to the uncontrolled reentry of a Falcon 9 second stage that scattered debris across multiple locations in Poland, European Spaceflight reports. The Falcon 9’s upper stage was supposed to steer itself toward a controlled reentry last month after deploying a set of Starlink satellites, but a propellant leak prevented it from doing so. Instead, the stage remained in orbit for nearly three weeks before falling back into the atmosphere February 19, scattering debris fragments at several locations in Poland.

A failure to communicate … In the aftermath of the Falcon 9’s uncontrolled reentry, the Polish Space Agency (POLSA) claimed it sent warnings of the threat of falling space debris to multiple departments of the Polish government. One Polish ministry disputed this claim, saying it was not adequately warned about the uncontrolled reentry. POLSA later confirmed it sent information regarding the reentry to a wrong email address. Making matters worse, the Polish Space Agency reported it was hacked on March 2. The Polish government apparently had enough and fired the head of the space agency March 11.

Vulcan booster anomaly blamed on “manufacturing defect.” The loss of a solid rocket motor nozzle on the second flight of United Launch Alliance’s Vulcan Centaur last October was caused by a manufacturing defect, Space News reports. In a roundtable with reporters Wednesday, ULA chief executive Tory Bruno said the problem has been corrected as the company awaits certification of the Vulcan rocket by the Space Force. The nozzle fell off the bottom of one of the Vulcan launcher’s twin solid rocket boosters about a half-minute into its second test flight last year. The rocket continued its climb into space, but ULA and Northrop Grumman, which supplies solid rocket motors for Vulcan, set up an investigation to find the cause of the nozzle malfunction.

All the trimmings … Bruno said the anomaly was traced to a “manufacturing defect” in one of the internal parts of the nozzle, an insulator. Specific details, he said, remained proprietary, according to Space News. “We have isolated the root cause and made appropriate corrective actions,” he said, which were confirmed in a static-fire test of a motor at a Northrop test site in Utah in February. “So we are back continuing to fabricate hardware and, at least initially, screening for what that root cause was.” Bruno said the investigation was aided by recovery of hardware that fell off the motor while in flight and landed near the launch pad in Florida, as well as “trimmings” of material left over from the manufacturing process. ULA also recovered both boosters from the ocean so engineers could compare the one that lost its nozzle to the one that performed normally. The defective hardware “just stood out night and day,” Bruno said. “It was pretty clear that that was an outlier, far out of family.” Meanwhile, ULA has trimmed its launch forecast for this year, from a projection of up to 20 launches down to a dozen.

When Europe needed it most, the Ariane 6 rocket finally delivered


“For this sovereignty, we must yield to the temptation of preferring SpaceX.”

Europe’s Ariane 6 rocket lifted off Thursday from French Guiana and deployed a high-resolution reconnaissance satellite into orbit for the French military, notching a success on its first operational flight.

The 184-foot-tall (56-meter) rocket lifted off from Kourou, French Guiana, at 11: 24 am EST (16: 24 UTC). Twin solid-fueled boosters and a hydrogen-fueled core stage engine powered the Ariane 6 through thick clouds on an arcing trajectory north from the spaceport on South America’s northeastern coast.

The rocket shed its strap-on boosters a little more than two minutes into the flight, then jettisoned its core stage nearly eight minutes after liftoff. The spent rocket parts fell into the Atlantic Ocean. The upper stage’s Vinci engine ignited two times to reach a nearly circular polar orbit about 500 miles (800 kilometers) above the Earth. A little more than an hour after launch, the Ariane 6 upper stage deployed CSO-3, a sharp-eyed French military spy satellite, to begin a mission providing optical surveillance imagery to French intelligence agencies and military forces.

“This is an absolute pleasure for me today to announce that Ariane 6 has successfully placed into orbit the CSO-3 satellite,” said David Cavaillolès, who took over in January as CEO of Arianespace, the Ariane 6’s commercial operator. “Today, here in Kourou, we can say that thanks to Ariane 6, Europe and France have their own autonomous access to space back, and this is great news.”

This was the second flight of Europe’s new Ariane 6 rocket, following a mostly successful debut launch last July. The first test flight of the unproven Ariane 6 carried a batch of small, relatively inexpensive satellites. An Auxiliary Propulsion Unit (APU)—essentially a miniature second engine—on the upper stage shut down in the latter portion of the inaugural Ariane 6 flight, after the rocket reached orbit and released some of its payloads. But the unit malfunctioned before a third burn of the upper stage’s main engine, preventing the Ariane 6 from targeting a controlled reentry into the atmosphere.

The APU has several jobs on an Ariane 6 flight, including maintaining pressure inside the upper stage’s cryogenic propellant tanks, settling propellants before each main engine firing, and making fine adjustments to the rocket’s position in space. The APU appeared to work as designed Thursday, although this launch flew a less demanding profile than the test flight last year.

Is Ariane 6 the solution?

Ariane 6 has been exorbitantly costly and years late, but its first operational success comes at an opportune time for Europe.

Philippe Baptiste, France’s minister for research and higher education, says Ariane 6 is “proof of our space sovereignty,” as many European officials feel they can no longer rely on the United States. Baptiste, an engineer and former head of the French space agency, mentioned “sovereignty” so many times, turning his statement into a drinking game crossed my mind.

“The return of Donald Trump to the White House, with Elon Musk at his side, already has significant consequences on our research partnerships, on our commercial partnerships,” Baptiste said. “Should I mention the uncertainties weighing today on our cooperation with NASA and NOAA, when emblematic programs like the ISS (International Space Station) are being unilaterally questioned by Elon Musk?

“If we want to maintain our independence, ensure our security, and preserve our sovereignty, we must equip ourselves with the means for strategic autonomy, and space is an essential part of this,” he continued.

Baptiste’s comments echo remarks from a range of European leaders in recent weeks.

French President Emmanuel Macron said in a televised address Wednesday night that the French were “legitimately worried” about European security after Trump reversed US policy on Ukraine. America’s NATO allies are largely united in their desire to continue supporting Ukraine in its defense against Russia’s invasion, while the Trump administration seeks a ceasefire that would require significant Ukrainian concessions.

“I want to believe that the United States will stay by our side, but we have to be prepared for that not to be the case,” Macron said. “The future of Europe does not have to be decided in Washington or Moscow.”

Friedrich Merz, set to become Germany’s next chancellor, said last month that Europe should strive to “achieve independence” from the United States. “It is clear that the Americans, at least this part of the Americans, this administration, are largely indifferent to the fate of Europe.”

Merz also suggested Germany, France, and the United Kingdom should explore cooperation on a European nuclear deterrent to replace that of the United States, which has committed to protecting European territory from Russian attack for more than 75 years. Macron said the French military, which runs the only nuclear forces in Europe fully independent of the United States, could be used to protect allies elsewhere on the continent.

Access to space is also a strategic imperative for Europe, and it hasn’t come cheap. ESA paid more than $4 billion to develop the Ariane 6 rocket as a cheaper, more capable replacement for the Ariane 5, which retired in 2023. There are still pressing questions about Ariane 6’s cost per launch and whether the rocket will ever be able to meet its price target and compete with SpaceX and other companies in the commercial market.

But European officials have freely admitted the commercial market is secondary on their list of Ariane 6 goals.

European satellite operators stopped launching their payloads on Russian rockets after the invasion of Ukraine in 2022. Now, with Elon Musk inserting himself into European politics, there’s little appetite among European government officials to launch their satellites on SpaceX’s Falcon 9 rocket.

The Falcon 9 was the go-to choice for the European Space Agency, the European Union, and several national governments in Europe after they lost access to Russia’s Soyuz rocket and when Europe’s homemade Ariane 6 and Vega rockets faced lengthy delays. ESA launched a $1.5 billion space telescope on a Falcon 9 rocket in 2023, then returned to SpaceX to launch a climate research satellite and an asteroid explorer last year. The European Union paid SpaceX to launch four satellites for its flagship Galileo navigation network.

European space officials weren’t thrilled to do this. ESA was somewhat more accepting of the situation, with the agency’s director general recognizing Europe was suffering from an “acute launcher crisis” two years ago. On the other hand, the EU refused to even acknowledge SpaceX’s role in delivering Galileo satellites to orbit in the text of a post-launch press release.

“For this sovereignty, we must yield to the temptation of preferring SpaceX or another competitor that may seem trendier, more reliable, or cheaper,” Baptiste said. “We did not yield for CSO-3, and we will not yield in the future. We cannot yield because doing so would mean closing the door to space for good, and there would be no turning back. This is why the first commercial launch of Ariane 6 is not just a technical and one-off success. It marks a new milestone, essential in the choice of European space independence and sovereignty.”

Two flights into its career, Ariane 6 seems to offer a technical solution for Europe’s needs. But at what cost? Arianespace hasn’t publicly disclosed the cost for an Ariane 6 launch, although it’s likely somewhere in the range of 80 million to 100 million euros, about 40 percent lower than the cost of an Ariane 5. This is about 50 percent more than SpaceX’s list price for a dedicated Falcon 9 launch.

A new wave of European startups should soon begin launching small rockets to gain a foothold in the continent’s launch industry. These include Isar Aerospace, which could launch its first Spectrum rocket in a matter of weeks. These companies have the potential to offer Europe an option for cheaper rides to space, but the startups won’t have a rocket in the class of Ariane 6 until at least the 2030s.

Until then, at least, European governments will have to pay more to guarantee autonomous access to space.

Welcome to Edition 7.01 of the Rocket Report! We’re compiling this week’s report a day later than usual due to the Independence Day holiday. Ars is beginning its seventh year publishing this weekly roundup of rocket news, and there’s a lot of it this week despite the holiday here in the United States. Worldwide, there were 122 launches that flew into Earth orbit or beyond in the first half of 2024, up from 91 in the same period last year.

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.

Firefly launches its fifth Alpha flight. Firefly Aerospace placed eight CubeSats into orbit on a mission funded by NASA on the first flight of the company’s Alpha rocket since an upper stage malfunction more than half a year ago, Space News reports. The two-stage Alpha rocket lifted off from Vandenberg Space Force Base in California late Wednesday, two days after an issue with ground equipment aborted liftoff just before engine ignition. The eight CubeSats come from NASA centers and universities for a range of educational, research, and technology demonstration missions. This was the fifth flight of Firefly’s Alpha rocket, capable of placing about a metric ton of payload into low-Earth orbit.

Anomaly resolution … This was the fifth flight of an Alpha rocket since 2021 and the fourth Alpha flight to achieve orbit. But the last Alpha launch in December failed to place its Lockheed Martin payload into the proper orbit due to a problem during the relighting of its second-stage engine. On this week’s launch, Alpha deployed its NASA-sponsored payloads after a single burn of the second stage, then completed a successful restart of the engine for a plane change maneuver. Engineers traced the problem on the last Alpha flight to a software error. (submitted by Ken the Bin)

Two companies added to DoD’s launch pool. Blue Origin and Stoke Space Technologies — neither of which has yet reached orbit — have been approved by the US Space Force to compete for future launches of small payloads, Breaking Defense reports. Blue Origin and Stoke Space join a roster of launch companies eligible to compete for launch task orders the Space Force puts up for bid through the Orbital Services Program-4 (OSP-4) contract. Under this contract, Space Systems Command buys launch services for payloads 400 pounds (180 kilograms) or greater, enabling launch from 12 to 24 months of the award of a task order. The OSP-4 contract has an “emphasis on small orbital launch capabilities and launch solutions for Tactically Responsive Space mission needs,” said Lt. Col. Steve Hendershot, chief of Space Systems Command’s small launch and targets division.

An even dozen … Blue Origin aims to launch its orbital-class New Glenn rocket for the first time as soon as late September, while Stoke Space aims to fly its Nova rocket on an orbital test flight next year. The addition of these two companies means there are 12 providers eligible to bid on OSP-4 task orders. The other companies are ABL Space Systems, Aevum, Astra, Firefly Aerospace, Northrop Grumman, Relativity Space, Rocket Lab, SpaceX, United Launch Alliance, and X-Bow.

Italian startup test-fires small rocket. Italian rocket builder Sidereus Space Dynamics has completed the first integrated system test of its EOS rocket, European Spaceflight reports. This test occurred Sunday, culminating in a firing of the rocket’s kerosene/liquid oxygen MR-5 main engine for approximately 11 seconds. The EOS rocket is a novel design, utilizing a single-stage-to-orbit architecture, with the reusable booster returning to Earth from orbit for recovery under a parafoil. The rocket stands less than 14 feet (4.2 meters) tall and will be capable of delivering about 29 pounds (13 kilograms) of payload to low-Earth orbit.

A lean operation … After it completes integrated testing on the ground, the company will conduct the first low-altitude EOS test flights. Founded in 2019, Sidereus has raised 6.6 million euros ($7.1 million) to fund the development of the EOS rocket. While this is a fraction of the funding other European launch startups like Isar Aerospace, MaiaSpace, and Orbex have attracted, the Sidereus’s CEO, Mattia Barbarossa, has previously stated that the company intends to “reshape spaceflight in a fraction of the time and with limited resources.” (submitted by EllPeaTea and Ken the Bin)

Mere days before its debut, the Ariane 6 rocket loses a key customer to SpaceX

Zut Alors! —

“I am impatiently waiting to understand what reasons could have led Eumetsat to such a decision.”

The flight hardware core stage for Europe’s new rocket, Ariane 6, is moved onto the launch pad for the first time. A launch is due to occur on July 9, 2024.

ESA-M. Pédoussaut

In a shocking announcement this week, the European intergovernmental organization responsible for launching and operating the continent’s weather satellites has pulled its next mission off a future launch of Europe’s new Ariane 6 rocket. Instead, the valuable MTG-S1 satellite will now reach geostationary orbit on SpaceX’s Falcon 9 rocket in 2025.

“This decision was driven by exceptional circumstances” said Phil Evans, director general of the organization Eumetsat. “It does not compromise our standard policy of supporting European partners, and we look forward to a successful SpaceX launch for this masterpiece of European technology.”

The decision, taken at a council meeting of Eumetsat’s 30 member nations on Wednesday and Thursday, comes less than two weeks before the debut of the Ariane 6 rocket, scheduled for July 9.

Stabbed in the back

Outwardly, at least, this decision reflects a lack of confidence in the reliability of the Ariane 6 rocket, the ability of European companies ArianeGroup and Arianespace to produce future versions of the Ariane 6, or both. It comes not just on the eve of the long-awaited debut of the Ariane 6, but also at a time when European officials are trying to close ranks and ensure that satellites built in Europe get launched on European rockets.

The retirement of the Ariane 5 rocket last July, and years of delays in the readiness for the Ariane 6 rocket, have led to a painful period in which European officials have had to come hat-in-hand to their longtime competitor and nemesis in the rocket industry, SpaceX, for launch services. As a result some of Europe’s most valuable missions, including the Euclid space telescope and several Galileo satellites, have already launched on the Falcon 9.

This has been embarrassing enough for European launch officials, who effectively created the concept of “commercial” space launch with the first Ariane rockets decades ago. For a long time, they, alongside Russia, were the kings of launching other people’s satellites. But now, on the eve of restoring European access to space, Eumetsat has effectively stabbed this industry in the back.

That is not too strong of language, either. In its release, Eumetsat described its new Meteosat Third Generation-Sounder 1 satellite as a “unique masterpiece of European technology.” The organization added, “This first European sounding satellite in a geostationary orbit will bring a revolution for weather forecasting and climate monitoring in Europe and Africa, and make it possible, for the first time, to observe the full lifecycle of a convective storm from space.” Critically, Eutmetsat was not willing to entrust this spacecraft to Europe’s new flagship rocket.

Philippe Baptiste, the chairman and chief executive of the French space agency CNES, certainly felt the sting, calling the decision a “brutal change” and saying it was a “disappointing day” for European space efforts.

“I am impatiently waiting to understand what reasons could have led Eumetsat to such a decision, at a time where all major European space countries as well as the European Commission are calling for launching European satellites on European launchers!” Baptiste wrote on LinkedIn. “Not mentioning the fact that we are 10 days away from the maiden flight of Ariane 6. How far will we, Europeans, go in our naivety?”

Why did they do this?

It is difficult to fully understand the motivations of Eumetsat in this decision. Most probably, there were some timing and reliability concerns. The MTG-S1 satellite was due to launch on the third flight of the Ariane 6 rocket, a mission nominally scheduled for early 2025. On this timeline the satellite very likely would have gotten to space more quickly than it otherwise would now on a Falcon 9.

However, because this 4-ton satellite is going to geostationary orbit, it would have been the first mission to require the use of a more powerful version of the Ariane 6 rocket. Instead of using two solid-rocket boosters, this “64” version of the rocket uses four solid-rocket boosters. It seems likely that Eumetsat officials had concerns that the timeline for this launch would drag out and perhaps some mission assurance concerns about being the first launch of an Ariane 64 rocket.

Whatever their reasons, the European satellite officials have thrown a massive turd into the punchbowl at festivities for the debut of the Ariane 6 rocket.

There was a panel discussion at a space conference in Singapore 11 years ago that has since become legendary in certain corners of the space industry for what it reveals about European attitudes toward upstart SpaceX.

The panel included representatives from a handful of launch enterprises, including Europe-based Arianespace, and the US launch company SpaceX. At one point during the discussion, the host asked the Arianespace representative—its chief of sales in Southeast Asia, Richard Bowles—how the institutional European company would respond to SpaceX’s promise of lower launch costs and reuse with the Falcon 9 rocket.

“What I’m discovering in the market is that SpaceX primarily seems to be selling a dream, which is good. We should all dream,” Bowles replied. “I think a $5 million launch or a $15 million launch is a bit of a dream. Personally, I think reusability is a dream. How am I going to respond to a dream? My answer to respond to a dream is, first of all, you don’t wake people up.”

To be fair to Bowles, at the time of his remarks, SpaceX had only launched the Falcon 9 five times by the middle of 2013. But his condescension was nevertheless something to behold.

Later in the discussion, Bowles added that he did not believe launching 100 times a year, something that SpaceX was starting to talk about, was “realistic.” Then, in a moment of high paternalism, he turned to the SpaceX official on the panel and said, “You shouldn’t present things that are not realistic.”

In response, Barry Matsumori, a senior vice president at SpaceX, calmly said he would let his company’s response come through its actions.

Actions do speak louder than words

Eleven years later, of course, SpaceX is launching more than 100 times a year. The company’s internal price for launching a Falcon 9 is significantly less than $20 million. And all of this is possible through the reuse of the rocket’s first stage and payload fairings, each of which have now proven capable of flying 20 or more times.

One might think that, in the decade since, European launch officials would have learned their lesson. After all, last year, the continent had to resort to launching its valuable Euclid Space Telescope on a Falcon 9 rocket. This year, because the new European Ariane 6 rocket was not yet ready after myriad delays, multiple Galileo satellites have been launched and will be launched on the Falcon 9 rocket.

Some officials have taken note. In a candid commentary last year, European Space Agency chief Josef Aschbacher acknowledged that the continent faced an “acute” launcher crisis amid the Ariane 6 delays and the rise of SpaceX as a launch competitor. “SpaceX has undeniably changed the launcher market paradigm as we know it,” Aschbacher wrote. “With the dependable reliability of Falcon 9 and the captivating prospects of Starship, SpaceX continues to totally redefine the world’s access to space, pushing the boundaries of possibility as they go along.”

But not everyone got the message, it seems.

Next month, the Ariane 6 rocket should finally make its debut. It will probably be successful. Europe has excellent technical capabilities in regard to launch. But from day one, the Ariane 6 launch vehicle will cost significantly more than the Falcon 9 rocket, which has similar capabilities, and offer no provision for reuse. Certainly, it will meet Europe’s institutional needs. But it likely will not shake up the market, nor realistically compete with a fully reusable Falcon 9.

Who really needs to be woken up?

And what about Starship? If and when SpaceX can deliver it to the market, the next-generation rocket will offer a fully reusable booster with five times the lift capacity of the Ariane 6 rocket for half its cost or less. How can Europe hope to compete with that? The European Space Agency’s director of space transportation, Toni Tolker-Nielsen—who works for Aschbacher, it should be noted—said he’s not concerned.

“Honestly, I don’t think Starship will be a game-changer or a real competitor,” he said in an interview with Space News. “This huge launcher is designed to fly people to the Moon and Mars. Ariane 6 is perfect for the job if you need to launch a four- or five-ton satellite. Starship will not eradicate Ariane 6 at all.”

In one sense, Tolker-Nielsen is correct. Starship will not change how Europe gets its small and medium-sized satellites into space. Made and launched in Europe, the Ariane 6 rocket will be a workhorse for the continent. Indeed, some European officials are going so far as to press for legislation mandating that European satellites launch on European rockets.

But to say Starship will not be a game-changer represents the same head-in-the-sand attitude displayed by Bowles a decade ago with his jokes about not waking the deluded dreamers up. In hindsight, it’s clear that the dreamers were not SpaceX or its customers. Rather, they were European officials who had lulled themselves into thinking their dominance in commercial launch would persist without innovation.

While they slumbered, these officials ignored the rise of reusability. They decided the Ariane 6 rocket should look like its expendable predecessors, with solid rocket boosters. Meanwhile, following the rise of the Falcon 9, nearly all new rocket projects have incorporated a significant reusability component. It’s no longer just SpaceX founder Elon Musk saying companies need to pursue reuse or perish. Almost everyone is.

Perhaps someone should wake Tolker-Nielsen up.

Welcome to Edition 6.42 of the Rocket Report! Several major missions are set for launch in the next few months. These include the first crew flight on Boeing’s Starliner spacecraft, set for liftoff on May 6, and the next test flight of SpaceX’s Starship rocket, which could happen before the end of May. Perhaps as soon as early summer, SpaceX could launch the Polaris Dawn mission with four private astronauts, who will perform the first fully commercial spacewalk in orbit. In June or July, Europe’s new Ariane 6 rocket is slated to launch for the first time. Rest assured, Ars will have it all covered.

German rocket arrives at Scottish spaceport. Rocket Factory Augsburg has delivered a booster for its privately developed RFA One rocket to SaxaVord Spaceport in Scotland, the company announced on X. The first stage for the RFA One rocket was installed on its launch pad at SaxaVord to undergo preparations for a static fire test. The booster arrived at the Scottish launch site with five of its kerosene-fueled Helix engines. The remaining four Helix engines, for a total of nine, will be fitted to the RFA One booster at SaxaVord, the company said.

Aiming to fly this year… RFA hopes to launch its first orbital-class rocket by the end of 2024. The UK’s Civil Aviation Authority last month granted a range license to SaxaVord Spaceport to allow the spaceport operator to control the sea and airspace during a launch. RFA is primarily privately funded but has won financial support from the European Space Agency, the UK Space Agency, and the German space agency, known as DLR. The RFA One rocket will have three stages, stand nearly 100 feet (30 meters) tall, and can carry nearly 2,900 pounds (1,300 kilograms) of payload into a polar Sun-synchronous orbit.

Arianespace wins ESA launch contract. The European Space Agency has awarded Arianespace a contract to launch a joint European-Chinese space science satellite in late 2025, European Spaceflight reports. The Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) is a 4,850-pound (2,200-kilogram) spacecraft that will study Earth’s magnetic environment on a global scale. The aim of the mission is to build a more complete understanding of the Sun-Earth connection. On Tuesday, ESA officially signed a contract for Arianespace to launch SMILE aboard a Vega C rocket, which is built by the Italian rocket-maker Avio.

But it may not keep it … In late 2023, ESA member states agreed to allow Avio to market and manage the launch of Vega C flights independent of Arianespace. When the deal was initially struck, 17 flights were contracted through Arianespace to be launched aboard Vega vehicles. While these missions are still managed by Arianespace, Avio is working with the launch provider to strike a deal that would allow the Italian rocket builder to assume the management of all Vega flights. The Vega C rocket has been grounded since a launch failure in 2022 forced Avio to redesign the nozzle of the rocket’s solid-fueled second-stage motor. Vega C is scheduled to return to flight before the end of 2024. (submitted by Ken the Bin)

Update on ABL’s second launch. ABL Space Systems expected to launch its second light-class RS1 rocket earlier this year, but the company encountered an anomaly during ground testing at the launch site in Alaska, according to Aria Alamalhodaei of TechCrunch. Kevin Sagis, ABL’s chief engineer, said there is “no significant delay” in the launch of the second RS1 rocket, but the company has not announced a firm schedule. “During ground testing designed to screen the vehicle for flight, an issue presented that caused us to roll back to the hangar,” Sagis said, according to Alamalhodaei. “We have since resolved and dispositioned the issue. There was no loss of hardware and we have validated vehicle health back out on the pad. We are continuing with preparations for static fire and launch.”

Nearly 16 months without a launch … ABL’s first RS1 test flight in January 2023 ended seconds after liftoff with the premature shutdown of its liquid-fueled engines. The rocket crashed back onto its launch pad in Alaska. An investigation revealed a fire in the aft end of the RS1 booster burned through wiring harnesses, causing the rocket to lose power and shut off its engines. Engineers believe the rocket’s mobile launch mount was too small, placing the rocket too close to the ground when it ignited its engines. This caused the hot engine exhaust to recirculate under the rocket and led to a fire in the engine compartment as it took off.

Welcome to Edition 6.36 of the Rocket Report! SpaceX wants to launch the next Starship test flight as soon as early May, the company’s president and chief operating officer said this week. The third Starship test flight last week went well enough that the Federal Aviation Administration—yes, the FAA, the target of many SpaceX fans’ frustrations—anticipates a simpler investigation and launch licensing process than SpaceX went through before its previous Starship flights. However, it looks like we’ll have to wait a little longer for Starship to start launching real satellites.

Starship could threaten small launch providers. Officials from several companies operating or developing small satellite launch vehicles are worried that SpaceX’s giant Starship rocket could have a big impact on their marketability, Space News reports. Starship’s ability to haul more than 100 metric tons of payload mass into low-Earth orbit will be attractive not just for customers with heavy satellites but also for those with smaller spacecraft. Aggregating numerous smallsats on Starship will mean lower prices than dedicated small satellite launch companies can offer and could encourage customers to build larger satellites with cheaper parts, further eroding business opportunities for small launch providers.

Well, yeah … SpaceX’s dedicated rideshare missions are already reshaping the small satellite launch market. The price per kilogram of payload on a Falcon 9 rocket launching a Transporter mission is less than the price per unit on a smaller rocket, like Rocket Lab’s Electron, Firefly’s Alpha, or Europe’s Vega. Companies operating only in the smallsat launch market tout the benefits of their services, often pointing to their ability to deliver payloads into bespoke orbits, rather than dropping off bunches of satellites into more standardized orbits. But the introduction of Orbital Transfer Vehicles for last-mile delivery services has made SpaceX’s Transporter missions, and potentially Starship rideshares, more attractive. “With Starship, OTVs can become the best option for smallsats,” said Marino Fragnito, senior vice president and head of the Vega business unit at Arianespace. If Starship is able to achieve the very low per-kilogram launch prices proposed for it, “then it will be difficult for small launch vehicles,” Fragnito said.

Rocket Lab launches again from Virginia. Rocket Lab’s fourth launch from Wallops Island, Virginia, and the company’s first there in nine months, took off early Thursday with a classified payload for the National Reconnaissance Office, the US government’s spy satellite agency, Space News reports. A two-stage Electron rocket placed the NRO’s payload into low-Earth orbit, and officials declared it a successful mission. The NRO did not disclose any details about the payload, but in a post-launch statement, the agency suggested the mission was conducting technology demonstrations of some kind. “The knowledge gained from this research will advance innovation and enable the development of critical new technology,” said Chris Scolose, director of the NRO.

A steady customer for Rocket Lab … The National Reconnaissance Office has become a regular customer of Rocket Lab. The NRO has historically launched larger spacecraft, such as massive bus-sized spy satellites, but like the Space Force, is beginning to launch larger numbers of small satellites. This mission, designated NROL-123 by the NRO, was the fifth and last mission under a Rapid Acquisition of a Small Rocket (RASR) contract between NRO and Rocket Lab, dating back to 2020. It was also Rocket Lab’s second launch in nine days, following an Electron flight last week from its primary base in New Zealand. Overall, it was the 46th launch of a light-class Electron rocket since it debuted in 2017. Rocket Lab is building a launch pad for its next-generation Neutron rocket at Wallops.

Night flight for Astrobotic’s Xodiac. The Xodiac rocket, a small terrestrial vertical takeoff and vertical landing technology testbed, made its first night flight, Astrobotic says in a statement. The liquid-fueled Xodiac is designed for vertical hops and can host prototype sensors and other payloads, particularly instruments in development to assist in precision landings on other worlds. This first tethered night flight of Xodiac in Mojave, California, was in preparation for upcoming flight testing with the NASA TechLeap Prize’s Nighttime Precision Landing Challenge. These flights will begin in April, allowing NASA to test the ability of sensors to map a landing field designed to simulate the Moon’s surface in near-total darkness.

Building on the legacy of Masten … Xodiac has completed more than 160 successful flights, dating back to the vehicle’s original owner, Masten Space Systems. Masten filed for bankruptcy in 2022, and the company was acquired by Astrobotic a couple of months later. Astrobotic’s primary business area is in developing and flying robotic Moon landers, so it has a keen interest in mastering automated landing and navigation technologies like those it is testing with NASA on Xodiac. David Masten, founder of Masten Space Systems, is now chief engineer for Astrobotic’s propulsion and test department. “The teams will demonstrate their systems over the LSPG (Lunar Surface Proving Ground) at night to simulate landing on the Moon during the lunar night or in shadowed craters.” (submitted by Ken the Bin)

United Launch Alliance

Welcome to Edition 6.32 of the Rocket Report! I’m writing the report again this week as Eric Berger is in Washington, DC, to receive a well-earned honor, the 2024 Excellence in Commercial Space Journalism Award from the Commercial Spaceflight Federation. Cape Canaveral is the world’s busiest spaceport, and this week, three leading US launch companies were active there. SpaceX launched another Falcon 9 rocket, and a few miles away, Blue Origin raised a New Glenn rocket on its launch pad for long-awaited ground testing. Nearby, United Launch Alliance began assembling an Atlas V rocket for the first crew launch of Boeing’s Starliner spacecraft in April. 2024 is shaping up to be a truly exciting year for the spaceflight community.

Astroscale inspector satellite launched by Rocket Lab. Astroscale, a well-capitalized Japanese startup, has launched a small satellite to do something that has never been done in space, Ars reports. This new spacecraft, delivered into orbit on February 18 by Rocket Lab, will approach a defunct upper stage from a Japanese H-IIA rocket that has been circling Earth for more than 15 years. Over the next few months, the satellite will try to move within arm’s reach of the rocket, taking pictures and performing complicated maneuvers to move around the bus-size H-IIA upper stage as it moves around the planet at nearly 5 miles per second (7.6 km/s).

This is a first … Astroscale’s ADRAS-J mission is the first satellite designed to approach and inspect a piece of space junk in orbit. This is a public-private partnership between Astroscale and the Japanese space agency. Of course, space agencies and commercial companies have demonstrated rendezvous operations in orbit for decades. The difference here is the H-IIA rocket is uncontrolled, likely spinning and in a slow tumble, and was never designed to accommodate any visitors. Japan left it in orbit in January 2009 following the launch of a climate monitoring satellite and didn’t look back. ADRAS-J is a technology demonstration that could pave the way for a follow-on mission to actually link up with this H-IIA rocket and remove it from orbit. Astroscale eventually wants to use these technologies for satellite servicing, refueling, and further debris removal missions. (submitted by Ken the Bin and Jay500001)

Software error blamed for Firefly launch malfunction. Firefly Aerospace released an update Tuesday on an investigation into an upper stage malfunction on the company’s Alpha rocket in December. The investigation team, consisting of membership from Firefly, the Federal Aviation Administration, the National Transportation Safety Board, Lockheed Martin, NASA, and the US Space Force, determined a software error in the rocket’s guidance, navigation, and control software algorithm ultimately caused the Alpha rocket to release its payload into a lower-than-planned orbit following a launch from California.

Upper stage woes… The software error prevented the rocket from sending the “necessary pulse commands” to control thrusters on the upper stage before its main engine was supposed to reignite. This second burn by the upper stage was supposed to circularize the rocket’s orbit, but it didn’t happen as planned. Still, the Alpha rocket safely released its commercial satellite payload for Lockheed Martin. Although the lower orbit caused the satellite to reenter the atmosphere earlier this month, Lockheed Martin said it was able to achieve many of the objectives of the technology demonstration mission, which focused on testing an electronically steered antenna. This was the fourth launch of an Alpha rocket, and two of them have suffered from upper stage malfunctions during engine restart attempts. Firefly says it is preparing the next Alpha rocket to fly “in the coming months.” (submitted by Ken the Bin)

A good fundraising round for Gilmour Space. Australian startup Gilmour Space Technologies has raised $55 million Australian dollars ($36 million) in a Series D funding round announced Monday, Space News reports. The funding supports the small launch vehicle startup’s campaign to manufacture, test, and begin launching rockets and satellites from the Bowen Orbital Spaceport in North Queensland. Gilmour Space, founded in 2012, is developing a three-stage rocket called Eris. The first Eris test flight is expected “in the coming months, pending launch approvals from the Australian Space Agency,” according to the Gilmour Space news release.

Launching from down under… Gilmour Space is aiming to launch the first Australian-built rocket into orbit later this year. The Eris rocket is powered by hybrid engines, and Gilmour says it is capable of delivering about 670 pounds (305 kilograms) of payload mass into a Sun-synchronous orbit. The $36 million fundraising round announced this week follows a $46 million fundraising round in 2021. According to the Australian Broadcasting Corporation, Gilmour Space is aiming for the first flight of Eris in April, and this latest fundraising should give the company enough money to mount four test flights.

Welcome to Edition 6.31 of the Rocket Report! Photographers at Cape Canaveral, Florida, noticed a change to the spaceport’s skyline this week. Blue Origin has erected a full-size simulator of its New Glenn rocket vertically on its launch pad for a series of fit checks and tests. Late last year, we reported Blue Origin was serious about getting the oft-delayed New Glenn rocket off the ground by the end of 2024. This is a good sign of progress toward that goal, but there’s a long, long way to go. It was fun to watch preparations for the inaugural flights of a few other heavy-lift rockets in the last couple of years (Starship, SLS, and Vulcan). This year, it’s New Glenn.

Russia launches a classified satellite. On February 9, Russia launched its first orbital mission of the year with the liftoff of a Soyuz-2-1v rocket from the Plesetsk Cosmodrome in the far north of the country. The two-stage rocket delivered a classified satellite into orbit for the Russian military, Anatoly Zak of RussianSpaceWeb.com reports. In keeping with the Russian military’s naming convention, the satellite is known simply as Kosmos 2575, and there’s little indication about what it will do in space, except for one key fact.

But wait, there’s more … It turns out the launch of Kosmos 2575 occurred at exactly the same time of day as another Soyuz-2-1v rocket launched on December 27 with a Russian military satellite named Kosmos 2574. The newer spacecraft launched into the same orbital plane as Kosmos 2574, a strong indication that the two satellites have a shared mission. In recent years, Russia has tested rendezvous, proximity operations, and, at least in one instance, a projectile that would have applications for an anti-satellite weapon. You can be sure the US military and a global community of hobbyist satellite trackers will watch closely to see if these two satellites approach one another. If they do, they could continue technology demonstrations for an anti-satellite system. It’s unclear if the recent revelations regarding US officials’ concerns about Russian anti-satellite capabilities are related to these recent launches.

European startup testing methane-fueled rocket engine. Space transportation startup The Exploration Company has continued testing its methane-fueled Huracán engine, which will power an in-space and lunar transportation vehicle under development, European Spaceflight reports. Most recently, the Huracán engine completed another round of thrust chamber testing using liquid methane fuel as a coolant and tested a new thermal barrier coating. The methane/liquid oxygen engine is undergoing testing at a facility in Lampoldshausen, Germany, ahead of use on The Exploration Company’s Nyx Moon spacecraft, a transfer vehicle designed for transportation to and from cislunar space and also capable of Moon landings. The Nyx Moon is an evolution of a transfer vehicle the European startup is developing to ferry satellites between different orbits around Earth.

Other uses for Huracán… The Exploration Company appears to be positioning itself not only as a builder and operator of orbital and lunar transfer vehicles but also as a propulsion supplier to other space companies. In 2022, The Exploration Company received funding for the Huracán engine from the French government. At the time, the company described the engine as serving the needs of “the upper stages of small launchers and those of orbital vehicles.” (submitted by Ken the Bin)
