SpaceX begins assembling first orbital Starship and Super Heavy booster
SpaceX has begun rapidly assembling the first orbital Starship prototype and the Super Heavy booster set to launch it isn’t far behind.
SpaceX’s Boca Chica, Texas rocket factory seemingly turned a corner in early July as sections of Starship 20 (S20) began to pop up around the site. Though parts labeled Starship “SN20” first appeared as far back as March 2021, the only unequivocal work on SpaceX’s first purportedly orbital-class Starship began in mid-June with the integration of the first engine section with mounts for six – not three – Raptors.
However, in line with SpaceX’s strict focus on maximizing the speed of Starship development and shortening the path to orbit, the company has frequently built Starship hardware before firmly assigning that hardware to any given ship, booster, or tank. In other words, until SpaceX actually begins stacking multiple completed rocket sections, there’s always a degree of uncertainty about the fate of any given ring, dome, or tank barrel. With Starship S20, that process began earlier this month and Super Heavy Booster 4 is likely to follow suit within the next few days – if it hasn’t already.
Since SpaceX unceremoniously rolled Starship prototype SN16 to an empty lot in mid-May, the company didn’t stack a single Starship part until the first week of July – unusual after a frenetic seven months spent building, qualifying, and launching Starships SN8, SN9, SN10, SN11, and SN15 and testing test tanks SN7.2 and BN2.1. Around the same time as Starship SN15 became the first prototype to successfully complete a high-altitude test flight and land in one piece, news broke that SpaceX was striving to perform Starship’s first orbital test flight with Ship 20 (S20) and Booster 3 (B3) as early as July.
Eventually, Booster 3’s orbital launch assignment shifted to Booster 4 as it became clear that the former prototype wasn’t meant to fly, but Starship S20 remained. More likely than not, the almost two-month gap between Starship SN16’s instant retirement and the start of the next flightworthy prototype’s assembly can be explained by the significant changes, upgrades, and undecided design decisions required to jump to S20.
Beyond the need for a thrust structure capable of supporting three sea-level Raptors and three vacuum-optimized engines, Starship S20 would need a full heat shield with thousands of tiles; orbital-class communications and avionics; and the general polished fit and finish required for an orbital launch attempt to have a good shot at producing the data needed for it to be valuable. SpaceX appeared to conclude that those stars were aligned in early July.
Two weeks after the first stack, Starship S20 is already approximately half-assembled and the last section of the vehicle’s tanks is almost ready for installation. What could be Starship S20’s nosecone is also in the late stages of assembly, though SpaceX has yet to even attempt to fully cover a nose in heat shield tiles and getting that process right could take an attempt or two.
Meanwhile, as evidenced by the booster common dome section hanging in midair in the image above, the assembly of Super Heavy booster 4 (B4) – the same booster tasked with supporting Starship’s first orbital launch attempt – may have begun on July 15th. If the Super Heavy common dome assembly was simply being moved relocated, a separate four-ring section has been staged outside of the high bay to kick off Booster 4 stacking within the next few days.
All told, it’s not inconceivable that both of the first orbital-class Starship and Super Heavy prototypes will be fully assembled and ready for testing – integrated or otherwise – sometime in August.

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.
