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 Sentry Mode helps lock up drive-by shooting suspect in Seattle
“A nearby Tesla actually captured the video that showed a man crouched behind a vehicle firing gunshots. A lot of vehicles record, and officers know that Teslas, especially, record, so we use that video all the time in these instances.”
Police in Seattle, Washington, are crediting Tesla’s well-known Sentry Mode for helping find a suspect in a drive-by shooting case.
A 21-year-old was arrested for an alleged drive-by shooting in the Pioneer Square neighborhood of Seattle this past Sunday, and the leads on the case seemed to be slim.
However, a Tesla parked nearby was able to record the shooting, as well as the car that the suspect hopped in after the crime occurred. It helped police identify the person they were looking for.
Seattle Police Department Detective Brian Pritchard said to MyNorthwest that the Tesla was a critical part of finding the suspect and placing him under arrest:
“A nearby Tesla actually captured the video that showed a man crouched behind a vehicle firing gunshots. A lot of vehicles record, and officers know that Teslas, especially, record, so we use that video all the time in these instances.”
The Tesla footage helped the Police put the suspect into handcuffs about an hour after the crime was committed. They are currently charged with drive-by shooting and unlawful possession of a firearm.
Tesla Sentry Mode is a security feature the vehicle utilizes to help solve crimes like vandalism, but it is also a cool feature that has caught things like accidents and other incidents on camera.
Many people still do not know about it, including the many vandals who keyed or broke the windows of Teslas earlier this year, as people damaged others’ cars in an act of retaliation against CEO Elon Musk when he became involved in politics.
This is far from the first time Sentry Mode has helped Police Departments solve crimes. Last September, we reported on Oakland’s Police Department in California using Teslas near crime scenes to help solve cases.
Tesla Sentry Mode is Oakland PD’s secret weapon against rising crime
Sergeant Ben Therriault, president of the Richmond Police Officers Association, said, “We have all these mobile video devices floating around,” in reference to the Teslas that sit and capture nearly everything that surrounds them.
Sentry Mode has helped officers arrest a variety of suspects, including several people who were allegedly involved in the murder of a 27-year-old woman in Northern California.

UPDATE: Tesla investors push Charles Schwab for Musk comp plan clarification
Update: 4:00 p.m. EDT – Charles Schwab has reached out to TESLARATI with the following statement, clarifying that it plans to vote FOR Musk’s compensation package:
“Schwab Asset Management’s approach to voting on proxy matters is thorough and deliberate. We utilize a structured process that focuses on protecting and promoting shareholder value. We apply our own internal guidelines and do not rely on recommendations from Glass Lewis or ISS. In accordance with this process, Schwab Asset Management intends to vote in favor of the 2025 CEO performance award proposal. We firmly believe that supporting this proposal aligns both management and shareholder interests, ensuring the best outcome for all parties involved.”
There have also been updates to the headline and various paragraphs to reflect this as well as accuracy.
Tesla investors are pushing Charles Schwab for clarification after it was expected to vote against CEO Elon Musk’s pay package.
Several high-profile Tesla influencers are speaking out against Charles Schwab, saying its decision to vote against the plan that would retain Musk as CEO and give him potentially more voting power if he can achieve the tranches set by the company’s Board of Directors.
The Tesla community appeared to see that Schwab is one firm that tends to vote against Musk’s compensation plans, as they also voted against the CEO’s 2018 pay package, which was passed by shareholders but then denied by a Delaware Chancery Court.
Schwab’s move was recognized by investors within the Tesla community and now they are speaking out about it:
Hey @CharlesSchwab – I need to speak with someone from Schwab Private Wealth Services this week. Please reach out via email, the mobile app message center, phone, or X DM.
Here’s why this is urgent: At least 6 of your ETF funds (around 7 million $TSLA shares) voted against… https://t.co/uSgPWnfTFc— Jason DeBolt ⚡️ (@jasondebolt) November 3, 2025
If @CharlesSchwab doesn’t vote for Elon Musk’s 2025 CEO Performance Award plan, I’ll move all my assets to another brokerage. My followers, many of whom also hold assets with Schwab and collectively own at least hundreds of millions in $TSLA, may do the same.
I can’t in good… https://t.co/6iUU6PdzYx— Sawyer Merritt (@SawyerMerritt) November 3, 2025
ready to help with the @CharlesSchwab exodus
— Gali (@Gfilche) November 3, 2025
At least six of Charles Schwab’s ETFs were expected to vote against Tesla’s Board recommendation to support the compensation plan for Musk. The six ETFs represent around 7 million Tesla $TSLA shares.
Jason DeBolt, an all-in Tesla shareholder, summarized the firm’s decision really well:
“As a custodian of ETF shares, your fiduciary duty is to vote in shareholders’ best interests. For a board that has delivered extraordinary returns, voting against their recommendations doesn’t align with retail investors, Tesla employees, or the leadership we invested to support. If Schwab’s proxy voting policies don’t reflect shareholder interests, my followers and I will move our collective tens of millions in $TSLA shares (or possibly hundreds of millions) to a broker that does, via account transfer as soon as this week.”
Tesla shareholders will vote on Musk’s pay package on Thursday at the Annual Shareholders Meeting in Austin, Texas.
It seems more likely than not that it will pass, but investors have made it clear they want a decisive victory, as it could clear the path for any issues with shareholder lawsuits in the future, as it did with Musk’s past pay package.

Tesla Cybertruck explosion probe ends with federal involvement and new questions
The 78-page document detailed a planned attack by former Green Beret Matthew Livelsberger, who died by suicide before the blast that injured six people.
The Las Vegas Metropolitan Police Department (LVMPD) has released its final investigative report into the New Year’s Day Cybertruck explosion outside the Trump International Hotel. But instead of bringing clarity, the findings have only raised more questions.
The 78-page document detailed a planned attack by former Green Beret Matthew Livelsberger, who died by suicide before the blast that injured six people.
The perpetrator’s manifesto
According to a Fox News report, Livelsberger rented the all-electric pickup through Turo while on leave from his Special Forces unit. He filled the rented Cybertruck with fireworks, gas cans, and camping fuel before driving it to the hotel shortly after 8:40 a.m. on January 1. Surveillance footage showed him pouring accelerant into the truck bed moments before detonation, confirming premeditation.
Livelsberger left a manifesto on his phone, which was later deemed classified by the Department of War. This case was then handed over to federal authorities. Still, the LVMPD and federal investigators noted in their report that the incident was a “vehicle-borne improvised explosive device” (VBIED) attack “with the potential to cause mass casualties and extensive structural damage.” Officials, however, stopped short of labeling it terrorism.
In digital notes, Livelsberger wrote that his act was not terror-related but intended as “a wake-up call,” criticizing what he called America’s “feckless leadership.” He wrote, “Americans only pay attention to spectacles and violence. What better way to get my point across than a stunt with fireworks and explosives.”
The incident ironically showcased the Cybertruck’s durability
Tesla CEO Elon Musk was among the first to respond publicly after the blast, confirming through X that the company’s senior team was investigating the incident. He later stated that vehicle telemetry showed no malfunction and that the explosion was caused by “very large fireworks and/or a bomb” placed in the Cybertruck’s bed.
Ironically, footage of the incident in the Cybertruck’s bed showed that the vehicle’s durable construction actually helped contain the explosion by directing the blast upwards. The bed remained largely intact after the explosion as well. Even more surprisingly, the Cybertruck’s battery did not catch fire despite the blast.
Months later, the same Cybertruck appeared on the online auction platform IAA, marked as “not ready for sale.” The listing has stirred debate among Tesla fans about why the historic vehicle wasn’t reclaimed by the company. The vehicle, after all, could serve as a symbol of the Cybertruck’s resilience, even in extreme circumstances.
