SpaceX repairing upgraded Starship prototype after first test
SpaceX workers have been spotted repairing the company’s newest Starship prototype in the days after the rocket’s first partial test.
Starship S24 was transported to SpaceX’s Starbase, Texas orbital launch site (OLS) on May 26th after about two and a half months of assembly, marking the first time SpaceX transported a new Starship prototype to a test stand since August 2021. Less than 24 hours later, after attaching Ship 24 to a new test bay located beside the actual ‘orbital launch mount,’ the Starship prototype came to life and began its first proof test.
Unfortunately, while it’s impossible to judge with certainty without official confirmation, Ship 24 either failed to complete that test or did not make it through unscathed.
Known as an ambient or pneumatic proof test, the main goal is to pressurize a Starship or Super Heavy prototype with nonflammable, ambient-temperature nitrogen gas to ensure that the rocket and all its plumbing are structurally sound and working as expected. A successful test would likely require a prototype to reach and sustain flight pressures – up to 8.5 bar (~125 psi) as of 2020 – without exhibiting any significant leaks or problems.
For a while, Ship 24’s first ambient proof test went about as expected, with lots of small vents from its main liquid oxygen (LOx) and methane (LCH4) tanks. No activity was visible at the ship’s nose, where vents and plumbing attach to a pair of small landing (header) propellant tanks. Ship 24 is the first Starship with an upgraded version of those tanks after SpaceX decided to remove the methane header tank from the main methane tank and relocate it directly under the oxygen header tank, which takes up the tip of Starship’s nose.
After an hour or two of testing, a muffled bursting noise different from previous vents was heard, followed by a quieter ‘whoosh’ more akin to a long vent. At the same time as the loud noise was heard, a good dozen or so of S24’s thousands of heat shield tiles were knocked off the section of the hull between the Starship’s main tanks and nose cone. SpaceX depressurized Ship 24 soon after and within a few hours, workers could be seen extracting a pipe from the ship that appeared to have been bent almost in half.
Three days later, workers were spotted guiding apparent replacement pipes into Ship 24. Altogether, it appears that some small section of Ship 24’s internal piping failed catastrophically after it was pressurized during the vehicle’s first pneumatic proof test, knocking tiles loose and possibly damaging other adjacent plumbing. Given the location of that piping inside Ship 24’s nose section, there’s a nonzero chance that the failure occurred when SpaceX attempted to pressurize the Starship’s new header tanks, which would have started by pressurizing the propellant and gas lines leading to them. That would explain the first muffled burst, the subsequent venting sound that slowly faded to nothing, and the loss of heat shield tiles.
It would also explain why SpaceX decided to leave Starship in place and conduct repairs at the pad. Super Heavy Booster 7, which suffered a dramatic plumbing failure during an early proof test, was moved back to one of Starbase’s covered assembly bays for repairs. Had Ship 24’s incident been severe, it would have likely left the pad as well. The fact that Ship 24 did not move indicates that the failure was fairly minor and contained, only impacting some easily-replaceable plumbing.
Additionally, SpaceX appears to have moved Raptor heat shield components and a missing cover for one of Ship 24’s four flaps to the pad since the incident. On top of the team that has been working all weekend to repair the Starship, other sets of workers have set about closing out Ship 24’s ‘raceway’, which protects hundreds of feet of smaller plumbing and cables and a flight termination system that runs from the top to the bottom of the ship’s tanks; and some have begun preparing to fill gaps in Ship 24’s heat shield. Most of that work can be classified as ‘finishing touches’ and none of it would be prioritized if Ship 24 was not in decent shape.
Still, even minor damage is a setback. Ship 24’s next opportunity for redemption is a 10am to 10pm CDT window on Wednesday, June 1st, with backup windows available on Thursday and Friday.
SpaceX is preparing for the 13th integrated flight test of its Starship system, with a targeted launch as early as Thursday, July 16. The 90-minute launch window opens at 5:45 p.m. CT from Starbase in South Texas.
This comes roughly seven weeks after Flight 12 on May 22, underscoring the company’s accelerating pace in its rapid development campaign. The mission will use the latest Starship and Super Heavy V3 vehicles equipped with Raptor 3 engines. Booster 20 will attempt a controlled boostback burn, followed by a splashdown in the Gulf of Mexico, while Ship 40 will follow a suborbital trajectory.

Key objectives for Flight 13 will include demonstrating reliable stage separation, engine performance under various conditions, and controlled reentry.
A major milestone for Flight 13 is the first deployment of 20 next-generation Starlink V3 satellites. These satellites feature advanced laser links for inter-satellite communication, deployable solar arrays, and onboard cameras, six of which will capture imagery of Starship’s heat shield during flight.
Several heat shield tiles on Ship 40 will be painted white to serve as imaging targets, while additional experiments test upgraded tiles on aft flaps, modified attachments on the aft skirt, and load-sensing tiles to measure stresses. The upper stage will also attempt a single Raptor engine relight in space before a targeted splashdown in the Indian Ocean.
These tests build directly on lessons from Flight 12, which introduced the V3 configuration but encountered issues including a booster flip anomaly during boostback and an engine-out event on the ship. Hardware and software modifications on Booster 20 and Ship 40 aim to improve engine relight reliability, startup sequencing, and overall robustness.

The short interval between Flights 12 and 13 highlights SpaceX’s iterative approach. Elon Musk has repeatedly emphasized that Starship launches will become “incredibly common” in the coming years.
The company envisions scaling to rates as high as one launch per hour within 4-5 years, potentially enabling thousands of flights annually. Such cadence is essential for Starship’s goals: establishing orbital refueling for lunar and Mars missions, deploying massive satellite constellations, and making life multiplanetary.
With each flight, Starship edges closer to full reusability and operational maturity. Success on July 16 would mark another step toward routine access to space and the ambitious vision of humanity becoming a spacefaring civilization.
Tesla shared a striking video showcasing the decommissioning of the original Model S and Model X assembly line at its Fremont Factory in Northern California. Completed in just 46 days, the teardown involved heavy machinery dismantling concrete pits, removing robotic arms and conveyors, and clearing the space for new production.
The post, captioned “End of an era,” captured both the end of a historic chapter and Tesla’s aggressive pivot toward its next major initiative, Optimus.

The decision to retire the Model S and Model X originated during Tesla’s Q4 2025 Earnings Call in late January 2026. CEO Elon Musk announced that production of the company’s flagship sedan and SUV would wind down by the end of Q2 2026, describing it as bringing the programs to an “honorable discharge.”
Custom orders ceased around early April 2026, with the final vehicles rolling off the line in early May. A special signature delivery ceremony on May 20 marked the emotional close for these vehicles, which had defined Tesla’s early success and luxury EV segment since the Model S launch in 2012.
The primary reason for tearing down the lines was to repurpose the valuable factory floor space for high-volume production of Tesla’s Optimus humanoid robot. Musk had indicated on Earnings Calls that the Fremont S/X line would be replaced by a dedicated Optimus manufacturing line targeting a capacity of one million units per year.
This move aligns with Tesla’s broader strategic shift from traditional vehicle manufacturing toward robotics and artificial intelligence, leveraging the company’s expertise in autonomy, AI training, and high-volume production.
Optimus, Tesla’s general-purpose humanoid robot, is designed to perform repetitive or dangerous tasks in factories, warehouses, and eventually homes. Powered by Tesla’s AI and Neural Networks, it aims to be a versatile, affordable platform. Production of Optimus Gen 3 is already underway in limited form at Fremont, with full-scale output on the converted line expected to begin in late July or August.
Tesla is targeting rapid scaling, with internal ambitions pointing toward tens or even hundreds of thousands of units annually by the end of 2026.
Longer-term, Tesla is constructing a much larger second-generation Optimus facility at Giga Texas, with potential capacity reaching millions of units per year. The company views Optimus as a transformative product that could eventually surpass its automotive business in scale and value, enabling widespread deployment of useful robots across industries. CEO Elon Musk has even predicted it would be the most popular product of all-time.
As one era closes at Fremont, another is rapidly taking shape.
Elon Musk posted a candid admission on his social media platform X on June 9, declaring that he had been “clearly wrong” about Anthropic. The statement marked a notable reversal from his earlier skepticism toward the AI company.
In September, Musk had written, “Winning was never in the set of possible outcomes for Anthropic,” reflecting his view at the time that the startup had lacked the foundation or even the trajectory to succeed in what is an incredibly intense race for advanced artificial intelligence.
Musk’s latest post came amid discussion of Anthropic’s reliance on external compute resources. He praised the company’s progress, stating that Anthropic is “obviously currently the leader in AI” and that “no company has released a model as good as Mythos/Fable,” with expectations of a strong follow-up in Mythos 2.
The tone shifted dramatically from dismissal to acknowledgement of superior performance.
I was clearly wrong about Anthropic. They are obviously currently the leader in AI. No company has released a model as good as Mythos/Fable and they will undoubtedly have Mythos 2 ready soon.
And I would never cut them off in a way that hurt them badly, even as a competitor.…

The context of Musk’s comments added significance. Anthropic has been operating under a recent compute deal with SpaceXAI, Musk’s AI infrastructure-focused venture. The pair entered a short-term GPU lease agreement initiated in May, providing Anthropic access to critical computing power for training and deploying its frontier models.

Some observers had speculated that Musk could leverage this dependency to disadvantage a rival. Musk directly addressed the possibility, writing, “I would never cut them off in a way that hurt them badly, even as a competitor. That’s not my style.”
To support his commitment to ethical competition, Musk referenced concrete examples from his other companies. Tesla famously open-sourced its entire portfolio of electric vehicle patents in 2014. The move was designed to accelerate the global adoption of sustainable transportation technology rather than protect proprietary advantages.
Tesla also made its Supercharger network available to competing electric vehicle manufacturers, transforming what could have remained an exclusive charging ecosystem into a shared infrastructure that benefits the broader industry and reduces barriers for EV adoption.
Musk further pointed to SpaceX’s practices, noting that the company launches satellites for competing commercial systems “with no increase in price or use of unfair terms.” He extended the principle to his social platform, observing that “even my worst enemies attack me on this platform,” underscoring preference for open discourse over retaliation.
These examples have illustrated Musk’s long-standing philosophy that long-term technological progress is best served by open competition and infrastructure sharing rather than leveraging market power to stifle rivals. In the fast-evolving AI sector, where compute resources and model capabilities determine leadership, Musk’s stance suggests a willingness to compete on innovation and performance alone.
Musk’s admission arrives as SpaceXAI itself advances its own frontier models while maintaining business relationships across the ecosystem. By publicly correcting his earlier assessment and reaffirming principles of fair play, Musk highlights a model of competition that prioritizes advancement of the field over short-term tactical advantages.
