SpaceX's Elon Musk works through holidays on Starship's "most difficult part"
SpaceX CEO Elon Musk says he has been working through the holidays at the company’s Boca Chica facilities to get Starship’s “most difficult part” ready for the next-generation spacecraft’s next prototype and flight tests.
Known as tank domes or bulkheads, Musk says that the hardware is the most difficult part of building and assembly Starship’s primary structure, referring to the steel engine section, tanks, and pointed nose that comprise most of the spaceship’s body. Starship’s primary structure must stand up to the rigors of all aspects of flight, including highly-pressurized propellant tanks, extreme G-forces during launches, orbital reentry, and more.
It was never officially determined whether the failure was intentional or not but during the first Starship prototype’s (Mk1) last test campaign, the vehicle experience an overpressure event while being filled with liquid oxygen or nitrogen. Localized to the weld connecting the upper tank dome to Starship’s cylindrical tank section, the dome essentially sheared off at the weld and launched hundreds of feet into the air, sending a shockwave through the vehicle that crumpled many of its steel structures as if they were aluminum foil.
It’s likely that Starship Mk1’s failure was an intentional overpressure event, meaning that SpaceX may have purposely pressed the vehicle’s tanks beyond their design limits to determine how structurally sound they were. What is less clear is whether the rocket burst before or after reaching its theoretical design limit.
For reference, SpaceX’s Falcon 9 rocket operates with its fuel and oxygen tanks pressurized to about 50 psi (3.5 atm) with localized pressures likely doubling or tripling near the bottom of both tanks during the first minute or two of launch. Some amateur back-of-the-envelope calculations from videos of Starship Mk1’s burst event suggest that it was pressurized to at least 60-75 psi (4-5 atm) at its upper tank dome, meaning that the pressure on its two lower domes and tank walls would have been even higher. If correct, those unofficial figures mean that Mk1 actually performed quite well considering the ramshackle facilities and unprecedentedly spartan methods used to fabricate and assemble it.
As such, Musk likely considers Starship’s tank domes the “most difficult part of [its] primary structure” in large part because of how difficult it is to make giant propellant tank domes simultaneously light and strong. Musk has previously implied that Starship Mk1 was more 200 tons (450,000 lb) empty while the ultimate goal for the spacecraft’s empty weight is closer to 120 tons, and a large portion of that weight savings will likely have to come from making its tank domes as light as possible.
In line with that educated speculation, the last month or so of SpaceX’s Starship work in Boca Chica, Texas has been marked by a distinct focus on building tank domes. In fact, Musk himself tweeted that he had worked all night with SpaceX engineers in Boca Chica in a bid to get dome production ready for Starship’s Mk3 prototype, the first Super Heavy hardware, and many more rockets to come.
Prior to Musk’s tweet, a Starship tank dome was actually shipped all the way from Florida to Texas and arrived earlier this month. Meanwhile, technicians have been briskly building up an additional dome using what appears to be a different method of integration involving new parts. SpaceX is currently attempting to weld Starship’s tank domes together from several dozen pre-formed sheets of stainless steel.
The sheets of steel assembled into the dome Musk showed on December 27th likely arrived in Boca Chica on December 13th, implying that SpaceX has managed to complete the majority of the first dome prototype – using a new process – in barely two weeks.
After SpaceX lifted the partially-completed dome off one of its custom assembly jigs, workers almost instantly began staging new sections of steel, beginning the process of integrating yet another tank dome – now likely the fourth on-site in Boca Chica. Meanwhile, at a nearby section of SpaceX’s Boca Chica production facilities, yet another dome was visible on the 28th. In short, SpaceX should soon have more than enough tank domes to complete the next Starship prototype – said to be a significantly improved and refined design compared to Mk1.
Known as Starship Mk3 (or Starship SN01), Musk says that the rocket – currently just a miscellaneous collection of separate parts – could (“hopefully”) be ready for its first flight as soon as February or March 2020.

Tesla is shifting FSD to a subscription-only model, confirms Elon Musk
Tesla CEO Elon Musk confirmed the upcoming update in a post on social media platform X.
Tesla will be ending one-time purchases of its Full Self-Driving (FSD) system after Valentine’s Day, transitioning the feature to a monthly subscription-only model.
Tesla CEO Elon Musk confirmed the upcoming update in a post on social media platform X.
No more FSD one-time purchases
As per Elon Musk in his post on X, “Tesla will stop selling FSD after Feb 14. FSD will only be available as a monthly subscription thereafter.” This marks a shift in how Tesla monetizes its FSD system, which can now be purchased for a one-time fee or accessed through a monthly subscription.
FSD’s subscription model has been $99 per month in the United States, while its one-time purchase option is currently priced at $8,000. FSD’s one-time purchase price has swung wildly in recent years, reaching $15,000 in September 2022. At the time, FSD was proficient, but its performance was not on par with v14. This made its $15,000 upfront price a hard sell for consumers.
Tesla’s move to a subscription-only model could then streamline how the company sells FSD. It also lowers the entry price for the system, as even price-conscious drivers would likely be able to justify FSD’s $99 monthly subscription cost during periods when long-distance travel is prevalent, like the holidays.
Musk’s compensation plan and FSD subscription targets
Tesla’s shift to a subscription-only FSD model comes amidst Musk’s 2025 CEO Performance Award, which was approved by Tesla shareholders at the 2025 Annual Shareholders Meeting with roughly 75% support. Under the long-term compensation plan, Musk must achieve a series of ambitious operational milestones, including 10 million active FSD subscriptions, over the next decade for his stock awards to vest.
The 2025 CEO Performance Award’s structure ties Musk’s potential compensation to Tesla’s aggressive targets that span market capitalization, vehicle deliveries, robotics, and software adoption. Apart from his 10-million active FSD subscription target, Musk’s compensation is also tied to Tesla producing 20 million vehicles cumulatively, delivering 1 million Tesla bots, and having 1 million Robotaxis in operation. He must also lead Tesla to a market cap of $8.5 trillion.
If successful, Elon Musk’s 2025 CEO Performance Award could make him the world’s first trillionaire. It could also help Tesla become the world’s most valuable company by market cap by a notable margin.
Tesla is planning for a new 300+ stall Supercharger station that will be an expansion of an existing facility, and the company is planning to add a surprise for the Semi.
The Firebaugh, California Supercharger is currently 72 Superchargers, but Tesla filed for an expansion that will add 232 additional plugs for passenger vehicles, and it also plans to add 16 Semichargers.
This will be the biggest Supercharger station Tesla will have to date, just months after it finished the Supercharger Oasis in Lost Hills, California, which has 168 stalls. This will have 304 total Supercharger stalls, and then the additional 16 Megachargers.
🚨 This Supercharger station will have 304 total stalls and 16 Semichargers following this expansion
Absolutely INSANE size 🔥
This is located on I-5, so many semis will be traveling along this route https://t.co/hM9hdLcWwg

The Firebaugh Supercharger is located on I-5, which is a major reason for why Tesla has chosen the location for additional Megacharger plug-ins, as Tesla Semi Program Manager Dan Priestley said on X earlier today.
Lots of trucks to electrify on I-5

The project was revealed by MarcoRP, a Supercharger tracker.
The expansion is a massive signal for charging demand, especially as Tesla’s Superchargers are opened to numerous automakers and are no longer exclusive to the company’s EVs. Additionally, the installation of Megachargers is a good sign to come for the Tesla Semi program, which aims to truly ramp up this year.
Tesla plans to launch production of the Semi later this year.
It could also mean Tesla is going to expand its footprint of large-scale Supercharger projects in the coming years, which would be a big boost as EV adoption continues to soar in the United States.
Tesla has made two big interior changes to several Model Y vehicles in its lineup, and the changes come just as the new model year begins production.
Last year, Tesla launched the Model Y Standard, which separated the previous models into the “Premium” category. The Standard vehicles lack several features, including more premium interior materials, acoustic-lined glass, and storage.
@teslarati There are some BIG differences between the Tesla Model Y Standard and Tesla Model Y Premium #tesla #teslamodely ♬ Sia – Xeptemper
The Model Y “Premium” trims are now getting several new upgrades, which come after the company launched a seven-seat configuration of the vehicle last night in the North American market for an upcharge of $2,500.
The new Model Y seven-seat configuration did not come with just an additional row of seating; it also came with a slew of other goodies that now come standard and were previously only available on the Model Y Performance, which was launched late last year.
All Black Headliner
The new Tesla Model Y Premium trims will now come standard with a black headliner, something that many owners have been requesting for some time.
The previous grey headliner and trim within the vehicle is now gone; it will be all black on all of the Premium trims from here on out, a welcome change:

Larger and Higher Resolution Center Touchscreen
The center touchscreen in the new Model Y Premium configuration is now larger and has a higher resolution than the previous version.
In last year’s Model Y configurations (apart from the Performance), the center touchscreen was 15.4″. Now, Tesla has decided to go with the 16″ version across all Premium trims, which is a nice step up. It was nice to see this in the Performance, but it is really great to see Tesla include this in the Model Y’s more Premium trim levels.
Tesla Model Y Seven Seater
Tesla launched the latest iteration of the seven-seater for the Model Y on Monday night. Traditionally, the Model Y seats five passengers in total, but there were calls for a more spacious version several years ago.
Tesla released it, but it was extremely tight in the back, basically reserving those back seats for only small people or children.

The new configuration looks to be slightly more spacious in the third row, but not as much space as most would require or want. Instead,
