SpaceX rolls upgraded Super Heavy booster to the launch pad

Published

SpaceX has begun transporting an upgraded Super Heavy booster to its South Texas launch facilities, where the rocket will likely be tested with a rarely used stand known as the ‘can crusher’.

On Wednesday, March 30th, SpaceX scheduled a temporary road closure – indicative of transport operations – on March 31st. The Friday prior, Super Heavy Booster 7 (B7) left the high bay it was assembled in multiple times, only to roll back inside at the end of the day. More likely than not, SpaceX decided to keep working on the booster inside the shelter of the high bay while a different team focused on preparing Starbase’s orbital launch site (OLS) for B7’s arrival. Simultaneously, moving Booster 7 also made room for SpaceX to begin stacking Booster 8, which began the same day.

Work at the pad has centered around one thing in particular: a massive mechanical device affectionately known as the ‘can crusher.’ Made up of two large steel structures, that structural test stand’s primary purpose is, to some degree, to attempt to crush Starship test tanks and Super Heavy prototypes. SpaceX transported the bottom half of the structural test stand to the orbital launch site a few days before Booster 7’s first brief trip outside the high bay.

A few days later, pictured in the tweet above, unofficial aerial photography of Starbase revealed that SpaceX has modified the stand with 13 hydraulic rams, all but guaranteeing that it will be used to test SpaceX’s next Super Heavy. B7 is the first booster designed to use upgraded Raptor V2 engines – and 33 of them, no less. Boosters 3 and 4 had room for 29 older Raptors. That ~14% increase in engine count required a redesigned thrust section, raising the number of central gimballing Raptors from 9 to 13.

Raptor V2’s upgrades are far more consequential, however. On top of major design simplifications that should slash the cost of manufacturing, Raptor V2’s maximum thrust was boosted from about 185 tons to 230+ tons (~410,000-510,000 lbf). Combined with more engines, Super Heavy Booster 7 could theoretically produce around 7600 tons (~16.7M lbf) of thrust at liftoff, while Booster 4 – which never fired even one of its 29 Raptor V1.5 engines – could have produced about 5400 tons (~11.9M lbf). That 40% increase in max thrust likely necessitated a similarly strengthened thrust section, involving a large number of mostly invisible design changes.

Those changes now need to be qualified and it appears that SpaceX may use B7 – an entire Super Heavy booster that could one day fly – to verify their performance instead of a cheaper, more disposable test tank. The first part of that testing will likely involve simulating the thrust of at least 13 of Booster 7’s engines. The test stand’s ‘cap’ could also be installed on top of Booster 7 once it arrives at the pad, possibly allowing SpaceX to simulate both the thrust of all 33 engines and the stress caused by acceleration during launch, reentry, and landing. Finally, SpaceX has begun installing a custom fixture and plumbing that will allow all of that structural testing to occur while Super Heavy is loaded with liquid nitrogen (LN2) or oxygen (LOx), adding another layer of stress.

SpaceX transported the structural test stand to the launch site on March 22nd and began installing plumbing that will connect Booster 7 to pad systems. A ‘cap’ could be added to simulate stresses during launch and the thrust of an outer ring of 20 more Raptors.(NASASpaceflight – bocachicagal)

Assuming the structural test stand is strong enough to support a several-thousand-ton booster, SpaceX could also feasibly complete cryogenic proof tests (with benign LN2 or LOx) and even wet dress rehearsals (with flammable LOx and methane propellant) with the same setup. Fully proofed, Booster 7 could then be fitted with Raptor 2 engines and installed on Starbase’s ‘orbital launch mount’ for static fire testing.

Based on road closures, SpaceX at least wants the option to begin testing Booster 7 as early as Friday, April 1st – the day after it arrives at the launch site. If test readiness slips further to the right, which is likely, additional opportunities are available on April 4th and 5th.

Tesla CEO Elon Musk hits back at drug use claims, calls publications ‘hypocrites’

Elon Musk showed a clean drug test, dispelling any rumors of drug use that came from unfounded reports from two large media outlets.

Tesla CEO Elon Musk has responded to a report from the Wall Street Journal and the New York Times, as both publications claimed he was abusing drugs while being involved with President Trump on both the campaign trail and while he was active within the administration after the election.

A bombshell report from the New York Times, published in late May, stated that Musk was regularly using things like ketamine, ecstasy, and psychedelic mushrooms, and also stimulants like Adderall, during his time within the Trump administration.

The reports cited inside sources who claimed the Tesla and SpaceX frontman was using substances during his time with the government.

However, Musk published the results of a recent drug test performed at Fastest Labs of South Austin. They showed ‘Negative’ results across the board:

Musk was not done there.

He went on to say the New York Times “lies as easy as breathing. It’s normal for them.” He also said both the Times and Wall Street Journal reporters should also publish their own drug test results, stating, “They won’t, because those hypocrites are guilty as sin.”

Musk said years ago that he received ketamine prescriptions from doctors to treat depression. He said he had it “years ago and said so on X, so this is not even news.” He also said that ketamine “helps for getting out of dark mental holes, but haven’t taken it since then.”

Tesla fans and Musk enthusiasts have joked for days now that, if Musk were to be on drugs, other CEOs should also do them, considering his persistence on work-related projects, long hours, and commitment to his job.

Musk has now proven that there has been no drug use with this test, and it seems as if the reports could have some sort of legal impact, although he has not said he will take any action.

Tesla’s Grok integration will be more realistic with this cool feature

Tesla is preparing Grok for its first integration into vehicles, but it’s making it more robust than ever, firmware shows.

Tesla has not yet integrated the AI assistant Grok into its vehicles, but when it does, it will be even more realistic with a new feature that firmware coding shows.

CEO Elon Musk teased a few months back that Grok would be making its way into vehicles in the near future. The implementation has not yet occurred, but we are confident it will be rolling out soon, especially as Tesla has its sights set on a near-term rollout of the Robotaxi platform.

Tesla’s vehicles expected to get Grok voice assistant—but when?

Grok will enable AI assistance for drivers who are both manually operating Tesla vehicles or using the company’s Full Self-Driving suite. It has been widely popular and extremely useful for users on X, Musk’s social media platform.

However, Tesla hacker green has revealed through firmware that the company is planning to roll out Grok into vehicles with personalities, giving it an even more realistic tone that is totally customizable and catered to whatever the driver wants.

There are also a handful of kids’ versions that will do things like tell stories or play trivia:

The true capabilities of Grok are nearly limitless. Back in January, Musk said on a livestream on X that, “You’ll be able to talk to your Tesla and ask for anything.”

Grok appears to only be available on AMD-based vehicles, according to other things green found in the firmware. This means that Intel-based Teslas, which are usually older models, will not enable Grok support for right now.

Tesla dominates Cars.com’s Made in America Index with clean sweep

Tesla continues to dominate Cars.com’s Made in America Index with a clean sweep of the Top 4 spots.

Tesla has dominated the Cars.com Made-in-America Index with a clean sweep of the top four spots. All four Tesla vehicles that were eligible for the analysis placed in the top four.

The Model 3 overtook the Model Y for first place this year. The all-electric crossover was first in 2024, but the Model 3 managed to overtake its sibling vehicle to claim the top spot in 2025. The Model Y took second, while the Model S took third, and the Model X took fourth.

This is an improvement from last year, as the Model Y took first, but the Model S and Model X placed fourth and ninth, respectively. The Model 3 was not in the Top 10 in 2024.

“Tesla continues to lead, claiming the top four spots and showcasing its commitment to domestic production. About 25% of the more than 400 vehicles on sale in the U.S. made this year’s AMI, and whether a vehicle is No. 1 or No.99, it contributes to the U.S. economy,” Patrick Masterson, lead researcher for the program, said.

More than 400 vehicles were analyzed for this year’s study, with Cars.com officially ranking 117 of them. There were two other EVs in the Top 10, as the Kia EV6 took sixth place, and the Volkswagen ID.4 finished in tenth.

This year’s study reflected major geographic and strategic shifts across the automotive industry. Of the 117 vehicles ranked in the program, they were produced at 36 domestic factories, leaving only 11 total factories that did not yield a car on the list. There are 47 assembly plants in operation in the U.S.

However, there still has not been a vehicle to quite reach the 100 percent domestic parts content, something that is extremely elusive. Masterson says the global supply chain is still extremely crucial to even the most American-built cars on the market.

The average domestic parts content of the Top 10 cars was 83.4 percent in 2006, but that number has shrunk to 70.3 percent in this year’s rankings.

Some might wonder where cars like the Tesla Cybertruck or Rivian R1T are on the list. However, these vehicles did not qualify because the study only considers cars under a gross weight of 8,500 pounds.
