A bit less than a month after SpaceX’s first full-scale Starship prototype was partially destroyed during testing, the damaged rocket has been almost completely scrapped to make way for new and improved Starships.

On November 20th, SpaceX effectively tested the Starship Mk1 – the first full-scale prototype – to destruction, pressurizing the rocket’s tank section (lower half) until it quite literally popped its top. The pressure wave that failure created damaged almost every internal component of the massive vehicle, all but guaranteeing that SpaceX would have to scrap the vehicle and move on to new prototypes.

Those future prototypes will take advantage of the many, many lessons learned from Starhopper’s two test flights and several additional grounded tests, as well as the many learning experiences presented through Starship Mk1’s pathfinder manufacturing, assembly, and test campaign. As is SpaceX’s signature, the company is choosing to learn by building actual hardware and making the inevitable mistakes that come hand in hand with such an eccentric and ambitious program.

Above all else, SpaceX is trying to redefine the minimum infrastructure needed to build high-performance launch vehicles at a scale comparable to or even larger than NASA’s Saturn V, the largest rocket ever successfully launched. Modern rockets like Falcon 9 and Atlas V are built in relatively clean and environmentally-controlled environments and Saturn I and V – while quite a bit less sterile – were at least built inside large hangar-like facilities.

With Starship, SpaceX instead wants to build rockets even larger than Saturn V out in the elements and with a far more common (and thus affordable) workforce, (theoretically) made possible in large part thanks to its extensive use of stainless steel. Case in point, Starhopper – a low-fidelity Starship test bed – was quite literally welded together on the South Texas coast by welders far more familiar with building water towers. While not without its teething pains, Starhopper proved to be incredibly sturdy and resistant to anomalous behavior and successfully performed two separate flight tests in July and August 2019.

Three months after Starhopper’s second and final hop test, SpaceX’s Starship Mk1 tank section – the lower half of the rocket – was moved to the launch site and began a series of tanking tests. The first few tests were completed successfully and focused on searching for leaks with a neutral cryogenic liquid (likely liquid nitrogen). After the majority of those leaks were sealed, SpaceX moved into liquid oxygen load testing a few days later. For unconfirmed reasons, it turned out that that first liquid oxygen pressure test would also be Starship Mk1’s last.

On November 20th, SpaceX pressurized Starship Mk1 to its limits, with almost all of the visible creases and wrinkles in its steel surface visibly smoothing out as the supercool liquid oxygen caused frost to form on the exterior. Ultimately, SpaceX pushed the vehicle beyond its limits and its uppermost tank dome quite literally popped off of Starship’s tank section, whether the overpressure event was intentional or unexpected. The force of that overpressure event essentially sent a shockwave through Starship, crushing and warping its two remaining tank domes and transfer tubes like an aluminum soda can.

In simpler terms, very few parts of Starship Mk1 escaped unharmed, all but guaranteeing that it would not be worth the effort to repair it. Instead, SpaceX has almost entirely scrapped the prototype over a period of two weeks. According to an official statement released shortly after Mk1’s failure, SpaceX will attempt to recover and reuse as much of Mk1 as it can and those few salvageable parts will be added to an entirely new prototype, deemed Starship Mk3.

Although it’s disappointing that Starship Mk1 was unable to perform any kind of Raptor engine testing, let alone flight tests, it’s safe to say that the pathfinder prototype has been well worth the time and effort it took to build. Regardless of flight or engine testing, a ton of Mk1’s value lies in its utility as a hands-on, physical testbed for SpaceX employees to perform experiments and learn how to build steel rockets – and build them outside in less than friendly weather conditions.

SpaceX is in the midst of rapidly expanding its presence in Boca Chica, Texas, including a new launch control center, an expanded landing and launch pad, new production facilities, and more. The company has also just begun churning out numerous monolithic (single-weld) steel rings that will likely become part of Starship Mk3 in the near future. It will likely be several months before that next-generation prototype is as close to completion as Starship Mk1 was, but it should be well worth the wait and well worth its predecessor’s sacrifice.

Elon Musk

Tesla Phone? Not quite, but close: analyst

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.

Tesla Full Self-Driving v14 ‘Lite’ for older cars finally gets released

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.”

Tesla will continue to roll out the v14 Lite suite more widely in the coming weeks, the company said.
