SpaceX’s first Super Heavy booster static fire slips to next week
Update: SpaceX has cancelled Thursday’s road closure, likely pushing Super Heavy’s first attempt at a static fire test into next week.
After an apparent false start on Wednesday morning, SpaceX has distributed a second safety alert among Boca Chica residents in anticipation of the first static fire of a Super Heavy booster as early as July 15th.
Delineated by highway and beach closures filed in advance with Cameron County, Thursday’s window stretches from 12pm to 8pm or 10pm CDT (UTC-5), giving SpaceX 8-10 hours to put the first functional Super Heavy booster prototype through its most challenging tests yet.
Known as a static fire, what is a mostly routine test for operational rockets is a bit more of a challenge for a first-of-its-kind prototype. Notably, on July 12th, Super Heavy Booster 3 survived its first ‘cryogenic proof’ pressure test, withstanding the thermal and mechanical stresses created when the rocket was filled with a few hundreds tons of liquid nitrogen and the expanding gases created as that cryogenic fluid then warmed and boiled. However, Booster 3 has yet to perform any kind of test involving the combustible, explosive liquid oxygen and methane propellant needed to fuel Raptor engines.
By all appearances, SpaceX aims to roll Super Heavy’s first wet dress rehearsal (WDR; like a ‘cryo proof’ with real propellant) and static fire into one busy day of testing. That combined WDR and static fire will likely be the first time ever that a launch vehicle as large as Super Heavy has attempted to pressurize its tanks autogenously, referring to the process of using a rocket’s own fuel and oxidizer to generate ullage gas. Starship prototypes notoriously struggled with their smaller autogenous pressurization systems – and jerry-rigged alternatives – on several occasions.
In other words, even an ignition-free wet dress rehearsal test completed with autogenous pressurization would be a major success and hurdle surmounted for Super Heavy. If SpaceX manages to perform the first booster WDR and static fire on the same day, it would indicate that the company has extreme confidence in Super Heavy.
Despite an aborted attempt on July 11th, SpaceX outfitted the rocket with one Raptor on Saturday, July 10th and installed another two engines in quick succession on Tuesday, July 13th – likely in an odd triangular configuration on the booster’s central nine-engine ‘thrust puck.’ Why that particular configuration was chosen instead of something more symmetric is unclear but it does decrease the odds of a multi-engine test on Super Heavy’s first static fire without a clear reason to assume that testing such an odd engine placement would provide some valuable insight.
In comparison, two engines on opposite sides of Super Heavy’s inner ‘ring’ or three engines forming a line across that ring are two configurations that boosters are very likely to use during landing burns. Regardless, according to Next Spaceflight’s Michael Baylor, SpaceX may start Super Heavy B3’s static fire test campaign with just one engine, so it’s not impossible that the current configuration is just a part of the incomplete process of installing five or more engines.
As with all Starship development, it’s equally likely that Super Heavy’s first wet dress rehearsal and static fire test attempts will slip late into the window, to Friday, or even to the week of July 19th. Stay tuned for updates!

Tesla Board member and Airbnb co-founder loads up on TSLA ahead of robotaxi launch
Tesla CEO Elon Musk gave a nod of appreciation for the Tesla Board member’s purchase.
Tesla Board member and Airbnb Co-Founder Joe Gebbia has loaded up on TSLA stock (NASDAQ:TSLA). The Board member’s purchase comes just over a month before Tesla is expected to launch an initial robotaxi service in Austin, Texas.
Tesla CEO Elon Musk gave a nod of appreciation for the Tesla Board member in a post on social media.
The TSLA Purchase
As could be seen in a Form 4 submitted to the United States Securities and Exchange Commission (SEC) on Monday, Gebbia purchased about $1.02 million worth of TSLA stock. This was comprised of 4,000 TSLA shares at an average price of $256.308 per share.
Interestingly enough, Gebbia’s purchase represents the first time an insider has purchased TSLA stock in about five years. CEO Elon Musk, in response to a post on social media platform X about the Tesla Board member’s TSLA purchase, gave a nod of appreciation for Gebbia. “Joe rocks,” Musk wrote in his post on X.
Gebbia has served on Tesla’s Board as an independent director since 2022, and he is also a known friend of Elon Musk. He even joined the Trump Administration’s Department of Government Efficiency (DOGE) to help the government optimize its processes.
Just a Few Weeks Before Robotaxi
The timing of Gebbia’s TSLA stock purchase is quite interesting as the company is expected to launch a dedicated roboatxi service this June in Austin. A recent report from Insider, citing sources reportedly familiar with the matter, claimed that Tesla currently has 300 test operators driving robotaxis around Austin city streets. The publication’s sources also noted that Tesla has an internal deadline of June 1 for the robotaxi service’s rollout, but even a launch near the end of the month would be impressive.
During the Q1 2025 earnings call, Elon Musk explained that the robotaxi service that would be launched in June will feature autonomous rides in Model Y units. He also noted that the robotaxi service would see an expansion to other cities by the end of 2025. “The Teslas that will be fully autonomous in June in Austin are probably Model Ys. So, that is currently on track to be able to do paid rides fully autonomously in Austin in June and then to be in many other cities in the US by the end of this year,” Musk stated.

Tesla China vehicle registrations rise 51% in April’s fourth week
In the week ending April 27, Tesla China saw 10,300 new vehicle registrations.
Tesla China’s new vehicle registrations saw a notable rise in the week of April 21-27, 2025. Over the week, the electric vehicle maker’s registrations saw an impressive 51% week-over-week rise, suggesting that domestic vehicle deliveries are on the rise once more.
Tesla China Results
In the week ending April 27, Tesla China saw 10,300 new vehicle registrations. This represents a notable rise from the company’s registration numbers in the past weeks of April. For context, Tesla China saw 3,600 registrations in the week ending April 6, 5,400 registrations in the week ending April 13, and 6,780 registrations in the week ending April 20, 2025.
Considering that April is the first month of the second quarter, expectations were high that Tesla China was allocating Giga Shanghai’s output for vehicle exports. With 10,300 registrations in the week ending April 27, however, it would appear that the company’s domestic deliveries are picking up once more.
Tesla China does not report its weekly sales figures, though a general idea of the company’s overall perforce in the domestic auto sector can be inferred through new vehicle registrations. Fortunately, these registrations are closely tracked by industry watchers, as well as some local automakers like Li Auto.
Tesla Model 3 and Model Y in Focus
Tesla China produces the Model Y and Model 3 in Giga Shanghai. Both vehicles are also exported from China to foreign territories. As per industry watchers, it would appear that both the Model 3 and Model Y saw an increase in registrations in the week ending April 27.
The Model 3, for one, appears to have seen 3,200 registrations in the week ending April 27, a 14% increase from the 2,800 that were registered in the week ending April 20. For context, Tesla China saw just 1,500 new Model 3 registrations in the week ending April 13 and 1,040 registrations in the week ending April 6.
The Model Y, on the other hand, saw 7,100 registrations in the week ending April 27. That’s a 77.5% increase from the 4,000 that were registered in the week ending April 20. Tesla also saw 3,900 registrations in the week ending April 13, and 2,540 registrations in the week ending April 6, 2025.
