Starhopper update: SpaceX’s ungainly Starship testbed survives night of fireballs, Raptor testing

Despite what looked like several decidedly off-nominal fires after an apparently successful Raptor static fire, Starhopper looks unscathed in the morning light. (NASASpaceflight - bocachicagal, 07/17/2019)

SpaceX’s Starhopper appears to have come out the other end of an eventful night of fires, fireballs, and Raptor testing completely unscathed, although – as with all things rocketry – there is vastly more than meets the eye.

However, signs point towards Starhopper being almost entirely unharmed by its brief voyage inside a fireball – even if Boca Chica’s fire suppression system got a thorough workout and many a SpaceX onlooker likely suffered a partial heart attack. For the time being, it’s safe to assume that Starhopper’s planned flight activities have been indefinitely delayed as SpaceX technicians analyze the vehicle and engineers work to mitigate or completely prevent major fires from recurring.

According to NASASpaceflight.com’s well-informed sources, despite the spectacular fireworks that followed Raptor’s own impressive display, the engine’s static fire test was a full success – at least in terms of data produced by the engine. The large fireball was attributed to the ignition of a large methane vent that followed soon after Raptor’s shutdown.

For now, this means that Starhopper’s untethered flight test and hover test debut should not be expected to occur for several days, even in the event that the rocket, pad, and Raptor engine all made it through their July 16th ordeal completely undamaged. If there is zero damage, this accident will serve as an unfortunate but useful demonstration of a true stainless steel rocket’s theoretically exceptional sturdiness and heat resistance.

It may seem more than a little ironic, but it’s likely less than a coincidence. If it comes to fruition as a truly functional, orbit-capable steel rocket, spaceship, and upper stage, Starship/Super Heavy will exist in their shiny, steel forms almost entirely because of the unintuitive tradeoffs that could theoretically make heat-resistant-but-dense steel more efficient than a ship built out of ultra-light carbon composites. If Starhopper’s newly demonstrated resilience is anything to go by, a very happy side-effect of that efficient, heat-resistant steel could be an almost unprecedented resilience in the face of serious fires, fireballs, and other fire-related anomalies.

For almost any other rocket, exposure – at least outside of the engine section – to large fireballs and quite literally having parts burning while motionless on the ground are deeply, deeply worrisome things and risk a major vehicle malfunction – potentially up to and including a catastrophic failure (i.e. explosion). ULA’s Delta IV rocket family is famous for self-immolating during ignition and liftoff, a minimal concern to the rockets’ thin, aluminum tankage thanks to several inches of thick, fire-retardant foam insulation.

For a rocket like Falcon 9, almost entirely (by surface area) composed of thin, aluminum propellant tanks and carbon composite structures, there is a constant struggle to balance the vehicle’s extreme performance with the low melting point of its primary structures (~720 degrees C). The 301-series stainless steel Starhopper and Starship(s) are built out of has a melting point of ~1400 degrees C, nearly double aluminum-lithium alloys.

~12 hours later, Starhopper and Raptor SN06 bare no visible scars after pushing through multiple fires and a large fireball on July 16th. (NASASpaceflight – bocachicagal, 07/17/2019)

In short, while it boggles the mind and is decidedly unintuitive to anyone who watched July 16th’s live coverage of the static fire, it’s actually not a huge surprise that Starhopper has suffered serious fire-related anomalies with essentially zero visible damage. In fact, it’s almost impossible to tell that anything at all happened, let alone discerning some subtle sign(s) of damage incurred by fires. It may sound ironic to say so, but rockets and fire just do not tend to like each other much at all.

Time will tell if Starhopper and Raptor are in as good a condition as they appear to be.

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 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.
