SpaceX preps Starship, Super Heavy for another week of Raptor testing
SpaceX continues to work around the clock to prepare its latest Starship and Super Heavy booster prototypes for another week of testing – likely focused on firing up the Raptor engines installed on each vehicle.
Known as Booster 7 and Ship 24, SpaceX has been slowly testing both prototypes for approximately four months, beginning in April and May, respectively. Only in early August did the company cautiously begin attempting to ignite their Raptor engines as part of a process known as static fire testing – by far the most difficult and important part of qualifying both vehicles for flight.
Thanks to progress made in 2021, SpaceX already has significant experience testing an earlier orbital-class Starship prototype on the ground, but the process of testing Ship 24 is still fresh and unfamiliar for a number of reasons. For Booster 7, the challenges are even greater.
On top of major design changes made to Starship and Super Heavy over the last year as SpaceX continues to refine the rocket, the company also developed a substantially different version of its Raptor engine. Compared to Raptor V1, Raptor V2 almost looks like a new engine and can produce around 25% more thrust (230 tons versus 185 tons). SpaceX has also tweaked how the engine operates, particularly around startup and shutdown, further weakening the value of past experience testing Raptor V1 and V1.5 engines on Ship 20 and Boosters 3 and 4.
In other words, with Ship 24 and Booster 7 engine testing, it’s possible that SpaceX is effectively starting from scratch. Many aspects of testing – propellant conditioning, thermal characteristics, tanking, detanking, certain test stands – are likely mostly unchanged, but almost every aspect of a rocket is affected by its engines.
Before SpaceX began testing Raptor V2 engines on Starship and booster prototypes, it wasn’t clear if the changes between V1.5 and V2 would invalidate a lot of prior testing. After the start of Booster 7 and Ship 24 static fire testing, it’s now clear that a lot of that earlier work has to be redone. It’s also clear that despite some of the simplifications in Raptor V2’s design, operating the engine on Starship and Super Heavy is much harder get get right.
Since mid-July, SpaceX has completed around 15-20 ‘spin-prime’ tests between Ship 24 and Booster 7 – more of that kind of test than any other prototype in the history of Starbase has performed. Spin-prime tests flow high-pressure gas through Raptor’s pumps to spin them up without igniting anything. It’s unclear why so many of those tests are being done, what SpaceX is gaining from it, or why the company appears to have completely stopped conducting preburner tests (a more life-like spin-prime with partial combustion).
Regardless, eight weeks after the start of engine testing, Booster 7 has only performed three static fires (two with one engine, one with a max of three or four engines), and Ship 24 has only completed one static fire with two engines. Before either vehicle can be considered ready for flight, a day that could easily never come, each will likely need to conduct multiple successful static fires with all of their Raptor engines (6 on S24 and 33 on B7).
If the pace of Booster 7 testing doesn’t change, the vehicle could be months away from a full 33-engine static fire attempt – perhaps the single most important and uncertain test standing between SpaceX and Starship’s first orbital launch attempt. Ship 24’s path to flight readiness should be simpler, but it appears to be struggling almost as much.
According to CEO Elon Musk, “an intense effort is underway” to ensure that Super Heavy B7’s Raptor engines are well contained during anomalies, so that one engine violently failing won’t damage or destroy the booster, other engines, or the launch pad. That could certainly complicate the process of testing Booster 7, and it’s likely that SpaceX is taking some of the same actions to protect Ship 24.
In early September, after a partially successful Booster 7 static fire (its first multi-engine test) and numerous additional Ship 24 tests that failed to achieve ignition, SpaceX replaced engines on both vehicles. Booster 7 had one of 13 Raptor Center engines swapped out, while Ship 24 had one of its three Raptor Vacuum engines replaced.
On September 5th, SpaceX distributed a safety alert to Boca Chica’s few remaining residents, confirming that it wants to restart testing as early as Tuesday, September 6th. Especially as of late, that alert guarantees nothing, but it does at least open the door for SpaceX if Ship 24, Booster 7, and the positions of the stars happen to be in the right mood between 8am and 8pm CDT. Additional opportunities are available on September 7th, 8th, 9th, and 12th.

Tesla recalls 6,197 Cybertrucks for light bar adhesive issue
On October 20, Tesla issued a voluntary recall of the impacted vehicles and has identified 619 warranty claims and just a single field report that is related to the issue.
Tesla has recalled 6,197 Cybertrucks for a light bar adhesive issue that was utilized by Service to install the aftermarket part.
According to the National Highway Traffic Safety Administration (NHTSA), impacted vehicles may have had the light bar “inadvertently attached to the windshield using the incorrect surface primer.”
Tesla identified an issue with the light bar’s adhesion to glass back in February and worked for months to find a solution. In October, the company performed chemical testing as a part of an engineering study and determined the root cause as the BetaPrime primer it utilized, figuring out that it was not the right surface priming material to use for this specific application.
On October 20, Tesla issued a voluntary recall of the impacted vehicles and has identified 619 warranty claims and just a single field report that is related to the issue.
The component is manufactured by a Romanian company called Hella Romania S.R.L., but the issue is not the primer’s quality. Instead, it is simply the fact that it is not the correct adhesive for this specific type of application.
Tesla says there are no reports of injuries or deaths due to this issue, and it will be resolved. In the 473 report that the NHTSA released this morning, Tesla said:
“At no charge to customers, Tesla will inspect the service-installed optional off-road light bar accessory for delamination or damage and if either is present, replace the light bar with a new light bar adhered with tape and a positive mechanical attachment. If no delamination or damage is present, Tesla will retrofit the service-installed optional off-road light bar accessory with a positive mechanical attachment.”
This is the third recall applied to Cybertrucks this year, as one on March 18 highlighted the potential for exterior trim panels to detach while driving, and another earlier this month when the NHTSA said its front parking lights were too bright.
Tesla resolved the first with a free assembly replacement, while the headlight issue was fixed with an Over-the-Air software update earlier this week. Owners said there was a noticeable difference in the brightness of the lights now compared to previously.

Tesla investor Calpers opposes Elon Musk’s 2025 performance award
Musk’s 2025 pay plan will be decided at Tesla’s 2025 Annual Shareholder Meeting, which will be held on November 6 in Giga Texas.
One of the United States’ largest pension funds, the California Public Employees’ Retirement System (Calpers), has stated that it will be voting against Elon Musk’s 2025 Tesla CEO performance award.
Musk’s 2025 pay plan will be decided at Tesla’s 2025 Annual Shareholder Meeting, which will be held on November 6 in Giga Texas. Company executives have stated that the upcoming vote will decide Tesla’s fate in the years to come.
Why Calpers opposes Musk’s 2025 performance award
In a statement shared with Bloomberg News, a Calpers spokesperson criticized the scale of Musk’s proposed deal. Calpers currently holds about 5 million Tesla shares, giving its stance meaningful influence among institutional investors.
“The CEO pay package proposed by Tesla is larger than pay packages for CEOs in comparable companies by many orders of magnitude. It would also further concentrate power in a single shareholder,” the spokesperson stated.
This is not the first time Calpers has opposed a major Musk pay deal. The fund previously voted against a $56 billion package proposed for Musk and criticized the CEO’s 2018 performance-based plan, which was perceived as unrealistic due to its ambitious nature at the time. Musk’s 2018 pay plan was later struck down by a Delaware court, though Tesla is currently appealing the decision.
Musk’s 2025 CEO Performance Award
While Elon Musk’s 2025 performance award will result in him becoming a trillionaire, he would not be able to receive any compensation from Tesla unless aggressive operational and financial targets are met. For Musk to receive his full compensation, for example, he would have to grow Tesla’s market cap from today’s $1.1 trillion to $8.5 trillion, effectively making it the world’s most valuable company by a mile.
Musk has also maintained that his 2025 performance award is not about compensation. It’s about his controlling stake at Tesla. “If I can just get kicked out in the future by activist shareholder advisory firms who don’t even own Tesla shares themselves, I’m not comfortable with that future,” Musk wrote in a post on X.

Tesla Cybercab is heading to China’s import expo
The event will take place from November 5–10 at Shanghai’s National Exhibition and Convention Center.
Tesla will make its return to the China International Import Expo (CIIE) this November, marking its first appearance at the event since 2022. The U.S. electric vehicle maker confirmed it will showcase its highly anticipated Cybercab, which will make its Asia-Pacific debut during the event.
The expo will take place from November 5–10 at Shanghai’s National Exhibition and Convention Center.
Tesla Cybercab in China
Tesla announced its participation in the event on its official Weibo account. As per the electric vehicle maker, it would be occupying Booth A3-03 in Hall 2.1 at the National Exhibition and Convention Center. As noted in a CNEV Post report, the Cybercab, the company’s dedicated autonomous two-seater Robotaxi, will be making its Asia-Pacific debut at the CIIE as well.
The company shared a graphic on Chinese social media which showed an image featuring several Tesla products, such as the Cybercab, Optimus, and Megapack batteries. The graphic also featured a building that read “Master Plan Part IV.”
Tesla’s momentum in China
Tesla’s return comes after skipping the event last year. Interestingly enough, Tesla attended the event from 2018 all the way to 2023. Tesla’s return to the CIIE then aligns with the company’s efforts to attract consumer interest in the world’s most competitive electric vehicle market.
The Cybercab’s presence in the event could suggest that Tesla might be interested in bringing its Robotaxi to the country. This is quite interesting as China is already home to several autonomous ride-hailing services, though Tesla’s pure vision approach, which focuses on artificial intelligence and cameras, is quite unique. So far, Tesla has only rolled out its autonomous ride-hailing services in Austin, Texas, and the Bay Area, California.
