SpaceX rolls Raptor Vacuum engines to launch pad for Starship’s next tests
For the second time, SpaceX is gearing up to install a full six Raptor engines on the first orbital-class Starship prototype.
This time around, though, there’s reason to believe that the preparations SpaceX is making aren’t a false start and could culminate in one or several record-breaking Starship static fires as early as next week.
SpaceX installed Raptors on Starship S20 for the first time in early August, outfitting the 50m (165 ft) tall prototype with a full six engines as part of a fit test that ultimately saw it installed on top of a Super Heavy booster. Ship 20 only spent an hour on top of Booster 4, though, and was quickly returned to Starbase build site for Raptor removal and final outfitting. Ship 20 was then rolled back to the launch site and installed on one of two suborbital launch mounts and test stands in mid-August, where it has sat ever since.
Between September 4th and 10th, SpaceX then appeared to install three sea-level-optimized Raptor Center (RC) engines and one Raptor Vacuum (RVac) engine on Starship S20 before the prototype had completed any proof testing. Whether that set of installs was a fit test or an aborted attempt at full installation, SpaceX seemingly paused at three or four Raptors and ultimately removed the lone RVac and one or more of S20’s sea-level engines. Another sea-level Raptor was (re)installed on September 15th.
After a frenetic month of back and forth with no obvious rhyme or reason, all of Ship 20’s Raptors were removed and a series of hydraulic rams used to simulate engine thrust – removed, unused, back in August – were reinstalled. Starship then completed pneumatic and cryogenic proof tests in the last few days of September.

After another ten or so days of unusual downtime, SpaceX began reinstalling Raptors on Ship 20 – one sea-level and one vacuum – around October 10th for a static fire test campaign that began about a week later. Finally, on October 21st, SpaceX fired up the orbital-class prototype for the first time, also completing the first test of a Raptor Vacuum engine installed on a Starship. Barely an hour later, Starship S20 performed a second test, simultaneously firing up both RVac and RC engine in another first.
Barely a full day after that successful back-to-back static fire test, SpaceX rolled two more sea-level Raptors to the suborbital pad and installed them on Ship 20. Another unusual week of downtime later and, on October 28th, SpaceX has rolled two more Raptor Vacuum engines from the build site to the launch pad and staged them beside Starship. Once installed, Starship S20 will, for the second time, be fully outfitted with six Raptors. Having already fired up two of those engines without needing either replaced, though, there’s a decent chance that all six will actually be used before Ship 20’s next bout of engine removal/installation deja vu.
SpaceX has never fired more than three engines at a time on a Starship prototype or at its suborbital test site, so a number of firsts potentially lay before Ship 20 as it nears a second round of static fire testing. There is some uncertainty as to whether the suborbital test stands can actually handle the stress from static fires with more than three Raptors, but if they can, then S20 will likely be the first prototype to ignite more 4+ engines and could become the first Starship to fire all six engines at once.
SpaceX currently has one possible test window scheduled from 10am to 6pm CDT on Monday, November 1st, though it could be another week or more before Starship S20’s next static fire attempt if past trends continue.

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.

Stellantis unveils solid-state battery for EVs
Stellantis validated solid state battery cells for EVs: ultra-dense, fast-charging, and AI-optimized. Launching demo fleet by 2026.

Stellantis N.V. and Factorial Energy have validated Factorial’s automotive-sized FEST® solid-state battery cells, a major milestone for next-generation electric vehicle (EV) batteries. The breakthrough positions Stellantis and Factorial to advance EV performance with lighter, more efficient batteries.
“Reaching this level of performance reflects the strengths of our collaboration with Factorial.
“This breakthrough puts us at the forefront of the solid-state revolution, but we are not stopping there.

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.
