SpaceX stacking two Starships at once for the first time in ten months
As of late November, SpaceX has begun stacking two Starship prototypes simultaneously for the first time in ten months.
Known as Starship S21 and S22, SpaceX began stacking the latter prototype inside Starbase’s ‘midbay’ in mid-October – the first Starship assembly work seen in more than two and a half months. For about half a year, SpaceX has been significantly more focused on Super Heavy production as it works to thoroughly test a booster for the first time. In the interim, the assembly of Starships – which already have an impressive history of ground and flight tests – slowed to a halt, though the production of Starship parts did not.
SpaceX builds Starships by forming structures and rings out of rolls, sheets, and billets of steel. For noses, domes, and header tanks, laser or waterjet-cut steel ‘gores’ (a bit like pizza slices) are welded together. Rolls of sheet metal are unspooled, cut into sections, and welded into individual rings that are then stacked on top of each other and robotically welded together around their circumference. Those ring sections – 9m (30 ft) wide and ranging from 2-4 rings tall (3.6-7.3m or 12-24 ft) – are then outfitted with stiffener rings and stringers to add rigidity and strength.
Once that basic structure is complete, parts are cut out or welded on to create structural supports, pass-throughs, and mounts for avionics (batteries, wiring, power, comms) hardware, plumbing, mechanical systems, and more. In the case of ships, robotic arms also weld on thousand of studs that eventually become anchors for heat shield tiles. At some point, certain partially-finished ring sections are ‘sleeved’ around tank domes, of which Starship and Super Heavy both have three. Finally, at some point in the early ‘life’ of a Starship or Super Heavy, SpaceX begins assembling the actual vehicle out of that collection of different sections. While weeks or even months of work always precede that milestone, the first stack is still the point at which SpaceX decides to turn those parts into an actual vehicle – never a guarantee, no matter how far along those parts appear to be.

That’s where Starship S21 and Starship S22 found themselves around October 17th and November 21st. Six weeks later, now side by side in Starbase’s midbay, Ship 21’s tank section is fully stacked and Ship 22’s tank section is close to two-thirds complete. Ship 22’s nose assembly – a nosecone and section of four rings – is still in two pieces, while Ship 21’s nose is fully integrated – heat shield included.
In the very near future, Starship S21’s tank section will be rolled from midbay to high bay for nose installation and Starship S22’s tank section will be topped off with its engine section and leg skirt. Perhaps as early as January, both ships could be fully stacked and more or less waiting in line for qualification testing ahead of Starship’s first few orbital launch attempts. Meanwhile, SpaceX is simultaneously preparing sections of Starship S23 and Super Heavy boosters B6 and B7 for possible assembly late this year or early next.

Tesla’s six-seat extended wheelbase Model Y L sold out for January 2026
Estimated delivery dates for new Tesla Model Y L orders now extend all the way into February 2026.
The Tesla Model Y L seems to be in high demand in China, with estimated delivery dates for new orders now extending all the way into February 2026.
This suggests that the Model Y L has been officially sold out from the rest of 2025 to January 2026.
Model Y L estimated delivery dates
The Model Y L’s updated delivery dates mark an extension from the vehicle’s previous 4-8 week estimated wait time. A detailed chart shared by Tesla data tracker @Tslachan on X shows the progressions of the Model Y L’s estimated delivery dates since its launch earlier this year.
Following its launch in September, the vehicle was given an initial October 2025 estimated delivery date. The wait times for the vehicle were continually updated over the years, until the middle of November, when the Model Y L had an estimated delivery date of 4-8 weeks. This remained until now, when Tesla China simply listed February 2026 as the estimated delivery date for new Model Y L orders.
Model Y demand in China
Tesla Model Y demand in China seems to be very healthy, even beyond the Model Y L. New delivery dates show the company has already sold out its allocation of the all-electric crossover for 2025. The Model Y has been the most popular vehicle in the world in both of the last two years, outpacing incredibly popular vehicles like the Toyota RAV4. In China, the EV market is substantially more saturated, with more competitors than in any other market.
Tesla has been particularly kind to the Chinese market, as it has launched trim levels for the Model Y in the country that are not available anywhere else, such as the Model Y L. Demand has been strong for the Model Y in China, with the vehicle ranking among the country’s top 5 New Energy Vehicles. Interestingly enough, vehicles that beat the Model Y in volume like the BYD Seagull are notably more affordable. Compared to vehicles that are comparably priced, the Model Y remains a strong seller in China.

NVIDIA CEO Jensen Huang commends Tesla’s Elon Musk for early belief
“And when I announced DGX-1, nobody in the world wanted it. I had no purchase orders, not one. Nobody wanted to buy it. Nobody wanted to be part of it, except for Elon.”
NVIDIA CEO Jensen Huang appeared on the Joe Rogan Experience podcast on Wednesday and commended Tesla CEO Elon Musk for his early belief in what is now the most valuable company in the world.
Huang and Musk are widely regarded as two of the greatest tech entrepreneurs of the modern era, with the two working in conjunction as NVIDIA’s chips are present in Tesla vehicles, particularly utilized for self-driving technology and data collection.
Nvidia CEO Jensen Huang regrets not investing more in Elon Musk’s xAI
Both CEOs defied all odds and created companies from virtually nothing. Musk joined Tesla in the early 2000s before the company had even established any plans to build a vehicle. Jensen created NVIDIA in the booth of a Denny’s restaurant, which has been memorialized with a plaque.
On the JRE episode, Rogan asked about Jensen’s relationship with Elon, to which the NVIDIA CEO said that Musk was there when nobody else was:
“I was lucky because I had known Elon Musk, and I helped him build the first computer for Model 3, the Model S, and when he wanted to start working on an autonomous vehicle. I helped him build the computer that went into the Model S AV system, his full self-driving system. We were basically the FSD computer version 1, and so we were already working together.
And when I announced DGX-1, nobody in the world wanted it. I had no purchase orders, not one. Nobody wanted to buy it. Nobody wanted to be part of it, except for Elon.
He goes ‘You know what, I have a company that could really use this.’ I said, Wow, my first customer. And he goes, it’s an AI company, and it’s a nonprofit and and we could really use one of these supercomputers. I boxed one up, I drove it up to San Francisco, and I delivered it to the Elon in 2016.”
The first DGX-1 AI supercomputer was delivered personally to Musk when he was with OpenAI, which provided crucial early compute power for AI research, accelerating breakthroughs in machine learning that underpin modern tools like ChatGPT.

GM CEO Mary Barra says she told Biden to give Tesla and Musk EV credit
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
General Motors CEO Mary Barra said in a new interview on Wednesday that she told President Joe Biden to credit Tesla and its CEO, Elon Musk, for the widespread electric vehicle transition.
She said she told Biden this after the former President credited her and GM for leading EV efforts in the United States.
During an interview at the New York Times Dealbook Summit with Andrew Ross Sorkin, Barra said she told Biden that crediting her was essentially a mistake, and that Musk and Tesla should have been explicitly mentioned (via Business Insider):
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”

Back in 2021, President Biden visited GM’s “Factory Zero” plant in Detroit, which was the centerpiece of the company’s massive transition to EVs. The former President went on to discuss the EV industry, and claimed that GM and Barra were the true leaders who caused the change:
“In the auto industry, Detroit is leading the world in electric vehicles. You know how critical it is? Mary, I remember talking to you way back in January about the need for America to lead in electric vehicles. I can remember your dramatic announcement that by 2035, GM would be 100% electric. You changed the whole story, Mary. You did, Mary. You electrified the entire automotive industry. I’m serious. You led, and it matters.”
People were baffled by the President’s decision to highlight GM and Barra, and not Tesla and Musk, who truly started the transition to EVs. GM, Ford, and many other companies only followed in the footsteps of Tesla after it started to take market share from them.

Musk would eventually go on to talk about Biden’s words later on:
“They have so much power over the White House that they can exclude Tesla from an EV Summit. And, in case the first thing, in case that wasn’t enough, then you have President Biden with Mary Barra at a subsequent event, congratulating Mary for having led the EV revolution.”
In Q4 2021, which was shortly after Biden’s comments, Tesla delivered 300,000 EVs. GM delivered just 26.
