SpaceX begins stress-testing upgraded Super Heavy booster
In a what is likely a prelude to engine installation, SpaceX has begun stress-testing an upgraded Super Heavy booster prototype.
Known as Super Heavy Booster 7 or B7, the prototype is the first of its kind designed to support up to 33 new Raptor V2 engines – each potentially capable of producing up to 230 tons (~510,000 lbf) of thrust at liftoff. Even with just 20 such engines installed, Super Heavy – measuring around 69 meters (~225 ft) tall and nine meters (~30 ft) wide – will be the largest and most powerful rocket stage ever tested. That potentially unprecedented power is why SpaceX has custom-built a complex structural test stand to explore Super Heavy’s true performance envelope in a slightly less risky manner.
In the second half of 2021, that structural test stand briefly tested an unusual half-Starship, half-Super Heavy test tank with a nine-engine thrust section (‘puck’) and later compressed a different test tank until its reinforced steel skin buckled. In the interim, SpaceX removed its nine-ram setup and modified the stand to support 13 rams, guaranteeing that its new purpose was to test Super Heavy’s new 13-engine thrust section. Prior to Booster 7, all Super Heavy prototypes have had a similar nine-engine puck and an outer ring of 20 engines that would attach directly to the rim of each booster’s cylindrical body.
Increasing the central engine count from 9 to 13 was already certain to up the amount of stress future Super Heavy thrust pucks would need to survive by almost 45%. But combined with Raptor V2’s thrust increases, Super Heavy Booster 7’s thrust puck could actually be subjected to at least 80% more thrust at liftoff. Altogether, Super Heavy B7’s 33 engines should be able to produce ~7600 tons (~16.8M lbf) of thrust compared to Super Heavy B4’s ~5400 tons (~11.9M lbf). As a result, though it’s odd that SpaceX never did significantly test Booster 4, it’s no surprise that the company chose to give Booster 7 priority as soon it was ready.
After a few false starts and at least one ‘pneumatic proof test’ that likely saw Booster 7 pressurized with benign nitrogen gas, SpaceX began stress-testing the upgraded Super Heavy in earnest on April 14th. First, the booster was filled about a third of the way with roughly 1000 tons (~2.2M lb) of liquid nitrogen (LN2) or a combination of liquid oxygen (LOx) and LN2. Once the rocket was fully chilled, there were clear signs of some kind of added stress as large sheets of ice that had formed on the side of B7’s skin broke apart and fell off.
Only ice close to Super Heavy’s base was visibly disturbed, increasing the odds that the behavior was a sign of some or all of the structural test stand’s hydraulic rams simulating Raptor engines. It’s also possible that the stress was caused by pressurizing Super Heavy’s tanks to the point that they began to appreciably deform, though that type of testing is far harder to differentiate. Without official comments, it’s unfortunately impossible to ever know what exactly SpaceX is testing or how successful those tests are when the structural test stand is involved.
Nonetheless, it’s likely that Booster 7 isn’t done with the stand just yet. SpaceX could benefit from just about any data gathered about the performance of Super Heavy’s new thrust puck during simulated Raptor startup, throttling, and shutdown both at liftoff and during boostback and landing burns. SpaceX might also want to simulate engine-out scenarios that would result in asymmetric thrust.
Assuming Booster 7 survives this particular series of tests and SpaceX is happy with its performance on the structural test stand, the upgraded Super Heavy could be ready for Raptor installation and integrated wet dress rehearsal and static fire testing in the near future. SpaceX began delivering upgraded Raptors V2 engines to Starbase in late March.

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.

Tesla investors are ditching Charles Schwab after its vote against Musk comp plan
Tesla investors are ditching Charles Schwab as their brokerage after the firm said earlier this week that it would vote against CEO Elon Musk’s new compensation 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 recognized 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

— Gali (@Gfilche) November 3, 2025
At least six of Charles Schwab’s ETFs have voted 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.
