While destined to remain on the ground, SpaceX has rolled Starship booster hardware to its Boca Chica, Texas launch pad for the first time.

Back in March, SpaceX completed the process of stacking Super Heavy booster number 1 (BN1), creating what amounted to the largest rocket booster ever assembled. Plans and designs ultimately changed during that several-month process, leading SpaceX to write off the first completed Starship booster structure as a “pathfinder” and scrap it before it could complete a single test. As a result, BN1 never made it to SpaceX’s nearby launch and test facilities and was unceremoniously cut into pieces days later.

Ten weeks after that development, SpaceX is well into the process of stacking its first flightworthy Super Heavy booster (BN2 or BN3) and has officially delivered the first real booster hardware to the launch site for crucial qualification testing.

While only a ‘test tank,’ BN2.1’s arrival at SpaceX’s South Texas launch facilities is an undeniable sign that the company has finally settled on some sort of firm design for Starship’s first-stage booster – at least enough for a custom test article to be worth the time, effort, and money to build and test. BN2.1 is the eighth custom test tank built by SpaceX in the last ~18 months but it’s the first such test article to center around hardware specific to Super Heavy.

Technically, thanks to the fact that Starship and Super Heavy are built out of the exact same steel rings, baffles, and stringers with almost identical production hardware, all past test tanks – and even full Starships – simultaneously mature large portions of Starship’s booster.

Super Heavy requires several unique parts and sections, though. Unlike Starship, which is designed to ultimately have six Raptor engines installed, the ship’s booster will have anywhere from 29 to 32 Raptors and have to withstand almost five times the mechanical stress. That necessitates a drastically different thrust structure for Super Heavy, as well as all additional structural elements to support the 20 Raptor engines – compared to three on Starship – that will mount to the interior wall of its skirt rings.

Beyond Super Heavy’s thrust puck, the booster also requires a much larger transfer tube to feed far more liquid methane through its oxygen tank, a custom dome to connect to that transfer tube, and a custom forward dome and ring section to support four vast grid fins.

BN2.1 is never going to (intentionally) fly and is just a single test tank, which rules out installing actual engines. Now routine, SpaceX’s solution to that challenge of qualifying new hardware without risking catastrophic pad damage has involved building short ‘test tanks’ that are then filled with nonexplosive liquid nitrogen (LN2) and mechanically stressed with hydraulic rams instead of actual engines. Thus far, that process has seemingly been successful time and time again and has helped SpaceX qualify new steel alloys, thinner skin, new welding techniques, and new ‘thrust puck’ designs for Starship.

SpaceX has also tested early full-scale prototypes with the same hydraulic ram systems as a further hedge against quality assurance or fluke design issues that might not have been caught with test tanks. Whether or not BN2.1 is successful, it’s safe to assume that SpaceX will put its first flightworthy Super Heavy booster through a similar thrust puck stress test before attempting wet dress rehearsals or static fires.

Wasting no time at all, SpaceX has already scheduled road closures for what is likely BN2.1’s first round of tests no earlier than (NET) 12pm to 8pm CDT (17:00-03:00 UTC) on Monday, June 7th, with backup windows on the 8th and 9th. Stay tuned to find out if Super Heavy’s thrust puck survives its first nine-engine thrust puck shuck.

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.

The long-term alliance between NVIDIA and Tesla has driven over $2 trillion in the company’s market value since 2016.

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.
