SpaceX’s most important Super Heavy booster part makes first appearance
What is arguably the most complex and important part of SpaceX’s Super Heavy booster prototype has made its first appearance at the company’s South Texas Starship factory.
Following in the footsteps of Starship development, Super Heavy has been able to extensively borrow from the many lessons learned over the course of building, testing, flying, and building more Starship prototypes. SpaceX is able to use virtually identical materials, equipment, and techniques to build and assemble both Starship and Super Heavy propellant tank barrels and domes, while both stages will also share an extensive foundation of avionics, plumbing, propulsion, and ground systems, among other things.
In fact, lacking a conical nose, secondary (‘header’) propellant tanks, flaps, a reusable orbital-class heatshield, and vacuum-optimized Raptor engines, Super Heavy is actually substantially simpler than the Starships it will one day launch towards orbit. However, not everything is simpler. Super Heavy will ultimately be the largest and most powerful liquid-fueled rocket stage ever built or tested – power that demands as many as 28 Raptor engines and a thrust structure capable of feeding and withstanding them.
Designing, building, and testing such a thrust structure is arguably one of – if not the – most challenging engineering hurdle standing between SpaceX and its aspirational Super Heavy design. It’s the first of those Super Heavy-specific thrust structures – in the form of a tank dome – that was spotted at SpaceX’s Boca Chica, Texas Starship factory on January 25th, roughly six weeks after its main component was spotted.
Unlike Starship, which relies on a small central ‘thrust puck’ fit for three sea-level-optimized Raptor engines and plans for three larger vacuum-optimized engines that will attach to the side of its hull, Super Heavy’s current design iteration features as many as 28 sea-level Raptors. Aside from CEO Elon Musk revealing that Super Heavy would have a central cluster of eight engines, the precise configuration has been a mystery.
The reality, as recently captured in photos above by NASASpaceflight photographers and contributors Mary (BocaChicaGal) and Jack Beyer, appears to be a much larger donut-shaped ring with space for eight gimballing Raptor engines. The remaining 20 Raptor engines would then be installed – possible mounted to the skirt, the thrust dome, or both – in the space left between the thrust donut and Super Heavy’s skirt.
Either way, the structures behind the two rings of engines will have to withstand at least 6600 metric tons (14.5 million lbf) of thrust at liftoff – approximately twice the thrust of Saturn V and Soviet N-1 rockets and more than three times the thrust of SpaceX’s own Falcon Heavy. Holding eight Raptors, the donut structure and dome recently pictured for the first time will also have to singlehandedly stand up to 1600 tons (3.5 million lbf; two Falcon 9s’ worth) of thrust while gravity, acceleration, and some 2500 tons of supercooled liquid oxygen push in the opposite direction.
In simpler terms, the business end of Super Heavy poses an extraordinarily difficult challenge and SpaceX has already built the first true-to-life prototype, with future iterations likely close on its heels. Much like Starship, if/when prototype booster number one (BN1) passes basic pressure and cryogenic proof tests, SpaceX will likely focus the rest of Super Heavy’s first test campaign on stressing the rocket’s unproven thrust structure to its design limits.
Like Starship, SpaceX will likely try to begin with nonexplosive methods, perhaps using a similar – but far larger – series of hydraulic rams to less riskily simulate the thrust of 8-28 Raptor engines. A steel structure spotted on a recent aerial overflight of SpaceX’s Starship factory might even fit the bill for such a structure, though only time will tell.
Based on an apparent acceleration of Super Heavy assembly work that may have started last week, as well as the crucial appearance of the last missing puzzle piece in the form of BN1’s thrust dome, the first booster could be completed and ready for testing sooner than later.

Tesla confirms Robotaxi is heading to five new cities in the U.S.
After launching in Austin, Texas, in late June and the Bay Area of California just a few weeks later, Tesla has been attempting to expand its Robotaxi suite to new states and cities in the U.S., and even outside of the country.
Tesla Robotaxi will hit five new cities in the United States in the coming months, the company confirmed.
After launching in Austin, Texas, in late June and the Bay Area of California just a few weeks later, Tesla has been attempting to expand its Robotaxi suite to new states and cities in the U.S., and even outside of the country.
The Robotaxi suite is a ride-hailing service Tesla offers, but the details of it change with each jurisdiction, as regulations vary. For example, in Austin, Tesla can operate the Robotaxi suite without anyone in the driver’s seat, as long as the vehicle does not enter a freeway.

In the Bay Area, a Safety Monitor rides in the driver’s seat, essentially acting as the vehicle operator with Full Self-Driving controlling the car.
The local regulations and how Tesla handles them will continue to be a relevant part of the discussion, especially as the company aims to expand the Robotaxi program to different areas. This has been a primary focus of the company for several months, especially within the United States.
CEO Elon Musk said that Tesla was aiming to launch Robotaxi in Nevada, Arizona, and Florida. However, the company detailed five specific cities where it will launch Robotaxi next during the Annual Shareholder Meeting on Thursday.
Tesla will launch Robotaxi in Las Vegas, Phoenix, Dallas, Houston, and Miami next, broadening its Service Area for the suite to more major cities across the U.S.
It has said it plans to offer the service to half of the U.S. population by the end of the year, but it does not seem as if it will expand to more than a handful of cities this year, which is still tremendous progress, all things considered.
As far as autonomy is concerned, Tesla has always had lofty expectations and has made some even loftier statements.
At the Shareholder Meeting, Musk said that the company would likely be able to enable vehicle owners to text while the vehicle drives, alleviating them from potentially having some of the responsibility they have behind the wheel.
Tesla says texting and driving capability is coming ‘in a month or two’
It is not confirmed that Tesla will roll this out in the next few months, but Musk said there is a possibility.

Tesla launches another new Model Y trim at a bargain price with massive range
It is the second most-affordable Model Y trim level in China, trailing the base Rear-Wheel-Drive and coming in under the All-Wheel-Drive.
Tesla has launched yet another new Model Y trim level, but this time it is in China, and it is at a bargain price.
It also has an insane range rating.
On Friday, Tesla launched the new Model Y Long Range Rear-Wheel-Drive in China, priced at 288,500 yuan ($40,500), an incredible deal considering it is not a stripped-down version of the vehicle like the Model Y Standard.
🚨🚨 Tesla’s new China-launched Model Y LR RWD offers 821 km (510 miles) CLTC range with 78.4 kWh CATL battery, beating AWD’s 750 km.
At 288,500 yuan ($40,500 USD), it fits between base RWD (593 km, 263,500 yuan) and AWD (313,500 yuan) for affordable long-range EVs.

It is the second most-affordable Model Y trim level in China, trailing the base Rear-Wheel-Drive and coming in under the All-Wheel-Drive.
The big appeal with this new Model Y trim is obviously its price, but its range rating is also one of the best we’ve seen. Rated at 821 kilometers on the CLTC scale, it converts to 510 miles. It uses a 78.4 kWh CATL battery.
Converted to real-world range, however, that 821-kilometer range rated by the CLTC actually is equivalent to about 357 miles on the EPA scale, which is still a very respectable number and comes in at a higher range than the Long Range All-Wheel-Drive configuration that is available in the U.S.
Tesla has truly brought a wide variety of Model Y trims to the Chinese market, including a new Model Y L configuration that features a slightly longer wheelbase, as well as additional interior features like extended thigh legrests and captain’s chairs with armrests.
It is unclear whether Tesla will bring a Premium Rear-Wheel-Drive option of the Model Y to the U.S., especially as it has already rolled out four configurations of the all-electric crossover in the market. With the new Standard offerings, Tesla will likely keep its lineup as simple as possible.
However, the company has hinted that there is a slim possibility the Model Y L could come to the U.S. sometime late next year, but CEO Elon Musk said that it is not a guarantee.
Tesla is more concerned with self-driving efforts in the U.S., and despite calls from customers for larger vehicles, it does not seem concerned with making them available, at least not for now.

Tesla Model Y Performance set for new market entrance in Q1
The lightning-fast trim level of the all-electric crossover packs a variety of new improvements, including more range and better acceleration, thanks to aerodynamic improvements and other performance-based changes.
Tesla’s new Model Y Performance is set to arrive in a new market in Q1 2026, a company executive confirmed on Friday.
The lightning-fast trim level of the all-electric crossover packs a variety of new improvements, including more range and better acceleration, thanks to aerodynamic improvements and other performance-based changes.
It was initially launched in Europe, and then it made its way to the United States. However, it will soon be available in a new market: Canada.
Raj Jegannathan, a Tesla executive, confirmed on Friday that the company would be bringing its Performance trim of the Model Y to the Canadian market early next year:
Q1
— Raj Jegannathan (@r_jegaa) November 8, 2025
Interestingly, the Model Y Performances that enter the Canadian market will likely come from Gigafactory Berlin and not Gigafactory Texas, even though it is logistically more advantageous.
There is a 25 percent tariff on U.S.-built vehicles currently, and Tesla has been sending Germany-built Model Y vehicles to Canada to avoid this and keep prices reasonable for customers.
Some Model Y owners in Canada have already confirmed that their units came from the German production facility, not the United States.
Model Y Performance deliveries have not yet started in the United States, but are slated for late November or early December.
Tesla refined the Model Y Performance’s exterior design with new front and rear fascia designs, a new performance carbon spoiler, 21″ Arachnid wheels and tires, and adaptive damping to help with better handling.
There are also new Drive Modes for better control during high-speed driving.
It also packs the same improvements as the new Model Y features over its predecessors, including acoustic glass and premium sound-damping materials for a quieter cabin, and heated and ventilated front sport seats.
In the United States, it is priced at $57,490. It will very likely be higher in Canada due to logistics costs and other factors.
