SpaceX crushes rocket engine world record during Raptor test
CEO Elon Musk has revealed that SpaceX crushed a global rocketry record during a recent Raptor engine test, pushing the crucial Starship component past years-old performance targets.
On August 17th, the SpaceX CEO unexpectedly released a photo of a Raptor test and a corresponding graph showing the engine’s chamber pressure, confirming that the company had successfully pushed the engine to record-breaking levels. Musk says that an unspecified Raptor – possibly serial number 39 (SN39) – briefly reached a main combustion chamber pressure of 330 bar (~4800 psi) during a controlled burn – and remained intact after shutdown.
Outside of subscale laboratory tests, the highest main combustion chamber known to full-scale, orbital-class rocketry was achieved by the Soviet Union in the 1980s with the RD-701 engine. Although the exceptionally unique engine was canceled before it could be used, it reportedly reached pressures of 290-300 bar in one mode of operation. Now, however, SpaceX and its Raptor engine appear to be the new world record holders – and by a huge margin.
Raptor’s new crown comes roughly 18 months after Elon Musk revealed that the engine had beaten the Soviet RD-270 full-flow staged combustion (FFSC) with a higher sustained chamber pressure (~257 bar vs 255 bar). A few days later, the same Raptor went even further, cresting the Russian RD-180 engine’s 257 bar operating pressure with a peak of 268 bar. Still, SpaceX needed 6-12 more months to refine Raptor into an engine capable of operating even close to those pressures for more than ~10 seconds. In July and August 2019, Raptor engine SN6 flew twice on Starhopper, culminating in a ~60-second, 150-meter hop that ended with the engine nearly destroying itself seconds before landing.
Almost exactly one year later, Raptor SN27 launched on Starship SN5 on the same 150m trajectory and appeared to perform flawlessly. Exhibiting barely a stutter or flare, SN27 never came close to the flamethrower-like death throes Raptor SN6 suffered in August 2019. In short, SpaceX continued to do what SpaceX does best, continuously refining rough prototypes into increasingly polished end products.
Originally revealed in 2016 as a methane/oxygen full-flow staged combustion engine with an operating combustion chamber pressure of 300 bar (4350 psi), Raptor’s August 17th achievement means that SpaceX has already exceeded one of its performance goals. Of course, combustion chamber pressure is significant but still far less important than engine longevity, burn duration limits, and reusability in the context of Starship. SpaceX likely wouldn’t be pushing the envelope of chamber pressure if it wasn’t confident about Raptor’s many other important attributes, but it’s still unknown if Raptor has ever burned for longer than ~90 seconds.
Regardless, if Raptor can actually sustain chamber pressures of 330 bar without damaging itself, the milestone could mean that SpaceX has already boosted Raptor’s maximum thrust from ~200 metric tons to ~225 metric tons (440,000-500,000 lbf. For Starship and Super Heavy, that 10% increase in thrust could easily translate to a 5-10% increase in payload to orbit per launch.
To reach orbit, though, Raptor still has a ways to go. For Super Heavy to be able to complete a normal launch, SpaceX will need to dramatically expand Raptor production (~31 engines per booster) and ensure that Raptor can reliably operate for 3-5+ minutes and reignite multiple times in flight. For Starship, SpaceX needs – at the minimum – to mature Raptor until it can burn continuously for 5-10 minutes to reach orbit. The company will likely also need to finish developing a custom vacuum-optimized version of Raptor for efficient orbital Starship flights.
Given just how quiet SpaceX is about most Raptor milestones, there’s a chance the company has already made substantial progress along those lines. For example, Starship SN8 – already well on its way to completion – will likely be the first prototype to fly with three Raptor engines and will need the ability to stop and start those engines in-flight to perform full-fidelity 20 km (~12.5 mi) launch and landing tests. Even just sustaining 330 bar for 10-100+ seconds without destroying the engine is likely several Raptor iterations away. Still, given SpaceX’s track record, all of those milestones are likely just a matter of time and perseverance.

Tesla Cybertruck’s newest trim will undergo massive change in ten days, Musk says
It appears as if the new All-Wheel-Drive trim of Cybertruck won’t be around for too long, however. Elon Musk revealed this morning that it will be around “only for the next 10 days.”
Tesla’s new Cybertruck trim has already gotten the axe from CEO Elon Musk, who said the All-Wheel-Drive configuration of the all-electric pickup will only be available “for the next ten days.”
Musk could mean the price, which is $59,990, or the availability of the trim altogether.
Last night, Tesla launched the All-Wheel-Drive configuration of the Cybertruck, a pickup that comes in at less than $60,000 and features a competitive range and features that are not far off from the offerings of the premium trim.
Tesla launches new Cybertruck trim with more features than ever for a low price
It was a nice surprise from Tesla, considering that last year, it offered a Rear-Wheel-Drive trim of the Cybertruck that only lasted a few months. It had extremely underwhelming demand because it was only $10,000 cheaper than the next trim level up, and it was missing a significant number of premium features.
Simply put, it was not worth the money. Tesla killed the RWD Cybertruck just a few months after offering it.
With the news that Tesla was offering this All-Wheel-Drive configuration of the Cybertruck, many fans and consumers were encouraged. The Cybertruck has been an underwhelming seller, and this seemed to be a lot of truck for the price when looking at its features:
- Dual Motor AWD w/ est. 325 mi of range
- Powered tonneau cover
- Bed outlets (2x 120V + 1x 240V) & Powershare capability
- Coil springs w/ adaptive damping
- Heated first-row seats w/ textile material that is easy to clean
- Steer-by-wire & Four Wheel Steering
- 6’ x 4’ composite bed
- Towing capacity of up to 7,500 lbs
- Powered frunk
It appears as if this trim of Cybertruck won’t be around for too long, however. Musk revealed this morning that it will be around “only for the next 10 days.”

Musk could mean the price of the truck and not necessarily the ability to order it. However, most are taking it as a cancellation.
If it is, in fact, a short-term availability decision, it is baffling, especially as Tesla fans and analysts claim that metrics like quarterly deliveries are no longer important. This seems like a way to boost sales short-term, and if so many people are encouraged about this offering, why would it be kept around for such a short period of time?
Some are even considering the potential that Tesla axes the Cybertruck program as a whole. Although Musk said during the recent Q4 Earnings Call that Cybertruck would still be produced, the end of the Model S and Model X programs indicates Tesla might be prepared to do away with any low-volume vehicles that do not contribute to the company’s future visions of autonomy.
The decision to axe the car just ten days after making it available seems like a true head-scratcher.

Elon Musk’s Neuralink sparks BCI race in China
One of the most prominent is NeuroXess, which launched in 2021 and is already testing implants in patients.
Neuralink, founded by Elon Musk, is helping spark a surge of brain-computer interface (BCI) development in China, where startups are moving quickly into human trials with strong state backing.
One of the most prominent is NeuroXess, which launched in 2021 and is already testing implants in patients.
Neuralink’s clinical work and public demonstrations have drawn worldwide attention to invasive brain implants that allow patients to control digital devices using their minds. The company is currently running a global clinical trial and is also busy preparing for its next product, Blindsight, which would restore vision to people with visual impairments.
Neuralink’s visibility has helped accelerate similar efforts in China. Beijing last year classified brain-computer interfaces as a strategic sector and issued a roadmap calling for two or three globally competitive companies by 2030, as per the Financial Times. Since February last year, at least 10 clinical trials for invasive brain chips have launched in the country.
NeuroXess recently reported that a paralyzed patient was able to control a computer cursor within five days of implantation. Founder Tiger Tao credited government support for helping shorten the path from research to trials.
Investment activity has followed the policy push. Industry data show dozens of financing rounds for Chinese BCI startups over the past year, reflecting rising capital interest in the field. Ultimately, while Neuralink remains one of the most closely watched players globally, its momentum has clearly energized competitors abroad.

Tesla Supercharger vandalized with frozen cables and anti-Musk imagery amid Sweden union dispute
The incident comes amid Tesla’s ongoing labor dispute with IF Metall.
Tesla’s Supercharger site in Vansbro, Sweden, was vandalized during peak winter travel weeks. Images shared to local media showed frozen charging cables and a banner reading “Go home Elon,” which was complete with a graphic of Musk’s controversial gesture.
The incident comes amid Tesla’s ongoing labor dispute with IF Metall, which has been striking against the company for more than two years over collective bargaining agreements, as noted in a report from Expressen.
Local resident Stefan Jakobsson said he arrived at the Vansbro charging station to find a board criticizing Elon Musk and accusing Tesla of strikebreaking. He also found the charging cables frozen after someone seemingly poured water over them.
“I laughed a little and it was pretty nicely drawn. But it was a bit unnecessary,” Jakobsson said. “They don’t have to do vandalism because they’re angry at Elon Musk.”
The site has seen heavy traffic during Sweden’s winter sports holidays, with travelers heading toward Sälen and other mountain destinations. Jakobsson said long lines formed last weekend, with roughly 50 Teslas and other EVs waiting to charge.
Tesla Superchargers in Sweden are typically open to other electric vehicle brands, making them a reliable option for all EV owners.
Tesla installed a generator at the location after sympathy strikes from other unions disrupted power supply to some stations. The generator itself was reportedly not working on the morning of the incident, though it is unclear whether that was connected to the protest.
The dispute between Tesla and IF Metall centers on the company’s refusal to sign a collective agreement covering Swedish workers. The strike has drawn support from other unions, including Seko, which has taken steps affecting electricity supply to certain Tesla facilities. Tesla Sweden, for its part, has insisted that its workers are already fairly compensated and it does not need a collective agreement,
Jesper Pettersson, press spokesperson for IF Metall, criticized Tesla’s use of generators to keep charging stations running. Still, IF Metall emphasized that it strongly distances itself from the vandalism incident at the Vansbro Supercharger.
“We think it is remarkable that instead of taking the easy route and signing a collective agreement for our members, they are choosing to use every possible means to get around the strike,” Pettersson said.
