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 issues statement on Starship V3 Booster 18 anomaly
The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX has issued an initial statement about Starship Booster 18’s anomaly early Friday. The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX’s initial comment
As per SpaceX in a post on its official account on social media platform X, Booster 18 was undergoing gas system pressure tests when the anomaly happened. Despite the nature of the incident, the company emphasized that no propellant was loaded, no engines were installed, and personnel were kept at a safe distance from the booster, resulting in zero injuries.
“Booster 18 suffered an anomaly during gas system pressure testing that we were conducting in advance of structural proof testing. No propellant was on the vehicle, and engines were not yet installed. The teams need time to investigate before we are confident of the cause. No one was injured as we maintain a safe distance for personnel during this type of testing. The site remains clear and we are working plans to safely reenter the site,” SpaceX wrote in its post on X.
Incident and aftermath
Livestream footage from LabPadre showed Booster 18’s lower half crumpling around the liquid oxygen tank area at approximately 4:04 a.m. CT. Subsequent images posted by on-site observers revealed extensive deformation across the booster’s lower structure. Needless to say, spaceflight observers have noted that Booster 18 would likely be a complete loss due to its anomaly.
Booster 18 had rolled out only a day earlier and was one of the first vehicles in the Starship V3 program. The V3 series incorporates structural reinforcements and reliability upgrades intended to prepare Starship for rapid-reuse testing and eventual tower-catch operations. Elon Musk has been optimistic about Starship V3, previously noting on X that the spacecraft might be able to complete initial missions to Mars.

Tesla analyst maintains $500 PT, says FSD drives better than humans now
The team also met with Tesla leaders for more than an hour to discuss autonomy, chip development, and upcoming deployment plans.
Tesla (NASDAQ:TSLA) received fresh support from Piper Sandler this week after analysts toured the Fremont Factory and tested the company’s latest Full Self-Driving software. The firm reaffirmed its $500 price target, stating that FSD V14 delivered a notably smooth robotaxi demonstration and may already perform at levels comparable to, if not better than, average human drivers.
The team also met with Tesla leaders for more than an hour to discuss autonomy, chip development, and upcoming deployment plans.
Analysts highlight autonomy progress
During more than 75 minutes of focused discussions, analysts reportedly focused on FSD v14’s updates. Piper Sandler’s team pointed to meaningful strides in perception, object handling, and overall ride smoothness during the robotaxi demo.
The visit also included discussions on updates to Tesla’s in-house chip initiatives, its Optimus program, and the growth of the company’s battery storage business. Analysts noted that Tesla continues refining cost structures and capital expenditure expectations, which are key elements in future margin recovery, as noted in a Yahoo Finance report.
Analyst Alexander Potter noted that “we think FSD is a truly impressive product that is (probably) already better at driving than the average American.” This conclusion was strengthened by what he described as a “flawless robotaxi ride to the hotel.”
Street targets diverge on TSLA
While Piper Sandler stands by its $500 target, it is not the highest estimate on the Street. Wedbush, for one, has a $600 per share price target for TSLA stock.
Other institutions have also weighed in on TSLA stock as of late. HSBC reiterated a Reduce rating with a $131 target, citing a gap between earnings fundamentals and the company’s market value. By contrast, TD Cowen maintained a Buy rating and a $509 target, pointing to strong autonomous driving demonstrations in Austin and the pace of software-driven improvements.
Stifel analysts also lifted their price target for Tesla to $508 per share over the company’s ongoing robotaxi and FSD programs.

SpaceX Starship Version 3 booster crumples in early testing
Photos of the incident’s aftermath suggest that Booster 18 will likely be retired.
SpaceX’s new Starship first-stage booster, Booster 18, suffered major damage early Friday during its first round of testing in Starbase, Texas, just one day after rolling out of the factory.
Based on videos of the incident, the lower section of the rocket booster appeared to crumple during a pressurization test. Photos of the incident’s aftermath suggest that Booster 18 will likely be retired.
Booster test failure
SpaceX began structural and propellant-system verification tests on Booster 18 Thursday night at the Massey’s Test Site, only a few miles from Starbase’s production facilities, as noted in an Ars Technica report. At 4:04 a.m. CT on Friday, a livestream from LabPadre Space captured the booster’s lower half experiencing a sudden destructive event around its liquid oxygen tank section. Post-incident images, shared on X by @StarshipGazer, showed notable deformation in the booster’s lower structure.
Neither SpaceX nor Elon Musk had commented as of Friday morning, but the vehicle’s condition suggests it is likely a complete loss. This is quite unfortunate, as Booster 18 is already part of the Starship V3 program, which includes design fixes and upgrades intended to improve reliability. While SpaceX maintains a rather rapid Starship production line in Starbase, Booster 18 was generally expected to validate the improvements implemented in the V3 program.
Tight deadlines
SpaceX needs Starship boosters and upper stages to begin demonstrating rapid reuse, tower catches, and early operational Starlink missions over the next two years. More critically, NASA’s Artemis program depends on an on-orbit refueling test in the second half of 2026, a requirement for the vehicle’s expected crewed lunar landing around 2028.
While SpaceX is known for diagnosing failures quickly and returning to testing at unmatched speed, losing the newest-generation booster at the very start of its campaign highlights the immense challenge involved in scaling Starship into a reliable, high-cadence launch system. SpaceX, however, is known for getting things done quickly, so it would not be a surprise if the company manages to figure out what happened to Booster 18 in the near future.
