SpaceX rolls upgraded Super Heavy booster to the launch pad
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.
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.
For years, there have been images and videos across social media platforms that have reminded me of when I was a 15-year-old kid teased by “Xbox 720” videos on YouTube. These videos are of the supposed “Tesla Phone” that Elon Musk was secretly developing in between leading Tesla with its electric cars and SpaceX with its reusable rockets.

Although Musk has put those rumors to bed several times, it was never completely out of the realm that he could get involved in cell phones in some capacity. Think outside the box and more macro-level, though. Instead of reinventing the computer, Musk reinvented connectivity by developing Starlink with SpaceX.
It could be something similar, TD Cowen analyst Gregory Williams said in a note last week, where he hinted SpaceX could be gathering some steam to acquire T-Mobile.
Williams said it would be the “clear choice” for SpaceX if it decided to go through with a network acquisition. He also suggested AT&T.
The move would be possible through selling more of its own stock, which would help SpaceX raise the money to purchase T-Mobile, which would cost roughly $300 billion. It could be one of the moves SpaceX makes post-IPO in terms of an acquisition: it already acquired Cursor AI for $60 billion.
Other analysts, like Dan Ives of Wedbush, believe SpaceX and Tesla will eventually merge into one anyway, and that conglomeration could come as soon as this year, some have said.
The implications of SpaceX purchasing T-Mobile are massive. A combined entity would create a truly ubiquitous network: T-Mobile’s terrestrial 5G towers and Starlink’s growing constellation of Direct-to-Cell satellites. This would essentially eliminate dead zones across the U.S. and potentially globally.
SpaceX would instantly become a full-scale facilities-based carrier with satellite differentiation; a huge advantage. This would pressure AT&T and Verizon heavily.
There are also concerns like a potential reduction in long-term competition, and of course, a deal of that size would face intense scrutiny from government agencies.
The strategic fit is compelling due to the existing Starlink–T-Mobile partnership and complementary technologies (space + terrestrial). It could create a dominant integrated communications player. However, the regulatory, financial, and execution hurdles are enormous — this remains highly speculative with no indication SpaceX is actively pursuing it right now.
Tesla revealed a major new Cybercab detail in a guide it released for First Responders, showing new territory in its beliefs and intentions for the ride-hailing-focused vehicle that entered production in April.
The First Responders Guide is released to give fire departments, paramedics, and other emergency personnel the proper guidance on what to do in the event of an accident, entrapment, or other situation that would require immediate attention.
On one of the pages of the First Responders Guide, Tesla revealed a stark detail about the Cybercab, which could help personnel enter the vehicle more easily in case of an emergency.
Tesla Cybercab has one important piece that AI4 cars might need for FSD
It shows Tesla has no intention of releasing any Cybercab units that were initially proposed for ride-hailing services for the general public with any manual controls, meaning a steering wheel or pedals:
“A Cybercab equipped with steering wheel, brake pedal, and an acceleration pedal is typically an engineering or test vehicle, and operates at SAE Level 2 autonomy. Cybercab is not typically equipped with a steering wheel or acceleration and brake pedals.”

This is a major development for those who continue to believe Tesla planned to release the Cybercab with any sort of manual controls so that passengers could take over if needed. However, when Tesla started manufacturing production versions of the Cybercab in Giga Texas earlier this year, they were spotted without a steering wheel or pedals.
It essentially confirms the company has no intentions of bringing manual controls to the car’s production versions. Some have argued that the likelihood of Tesla having something
There still are some Cybercab units out there with a steering wheel and pedals, and as Tesla said, these cars are engineering or test vehicles, which have Safety Monitors on board to help the car out of a precarious situation or emergency.
Tesla released the Full Self-Driving v14 ‘Lite’ suite to owners of Hardware 3 or AI3 vehicles today, adding several new features to the vehicles that were once believed to be capable of unsupervised self-driving.
Now, Tesla has released this modified suite to older Tesla vehicles, adding plenty of new features and capabilities.
Here are the full release notes for the suite:
- Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
- Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
- Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
- Introduced parking, unparking, and reversing capabilities.
- Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.
- Speed Profiles are now available at all times, to further customize driving style preference.
These improvements, according to Tesla’s Head of AI, Ashok Elluswamy, help distill the driving behavior from AI4’s v14 series into both the camera and compute configurations of AI3.

He added:
“It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.”
FSD v14 Lite is now rolling out to AI3 early-access customers. Based on the feedback, will rollout to more customers over the next few weeks.
