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.
Elon Musk is, in many respects, one of the biggest and most influential figures in modern-day artificial intelligence.
Given that Tesla, SpaceX, and xAI are all looked at in their respective fields as leaders to an extent, each of them has a heavy influence on the future of AI, even though two of them are not thought of, at face value, as AI companies.
Musk has grand expectations for what is to come with AI, not only as a form of assistance to make human lives easier, but to make humans multiplanetary and solve some of the biggest issues that face us today. But even he is astounded by AI’s pace of progress.
He believes that in two years, AI will be so mind-blowing it might be unrecognizable.
Given that AI from 2 years ago feels so old that it should be in a museum, then obviously AI 2 years from now will be mind-blowing https://t.co/TcsKZ8o8OE

This progress can be seen in a variety of ways, but perhaps the most popular way people have shown AI’s progress, especially on social media, is through an incredibly arbitrary way of watching Will Smith eat spaghetti:

This is a great way to show people how AI is improving, especially from a perspective that examines how it can manufacture images and video from prompts. AI is an incredibly complex concept, however, and it goes much deeper than Will Smith eating Italian food.
Musk’s most widely adopted method of AI is likely Tesla Full Self-Driving, which impacts millions of people as they utilize it to increase safety with their travel. Musk has routinely pushed incredibly aggressive timelines for self-driving, especially unsupervised.
Perhaps this perspective is why he feels that things will be solved in a timeframe that is much more aggressive than most of us would think. Regardless, the progress of AI is moving fast, and it seems that Musk’s expectations for it could be high.
But if it can actually achieve full-length motion pictures and even more realistic production value, it will be hard to distinguish between reality and AI very soon.
Tesla just officially confirmed it has built its 10 millionth car, a major milestone for the company that started producing sustainable electric powertrains less than two decades ago.
In that time, Tesla has truly revolutionized the automotive industry, disrupting the idea of what a car should be, how it should be fueled, and how it truly impacts day-to-day life.
10 million vehicles produced globally.

Tesla achieved this feat across four production facilities: the Fremont Factory in Fremont, California, Gigafactory Shanghai in China, Gigafactory Berlin in Germany, and Gigafactory Texas in Austin, Texas.
The 10 millionth vehicle was a Diamond Black Model Y.
Over the course of the past roughly 18 years, Tesla has evolved its lineup from a sporty sedan built on a Lotus body to a lineup of various body styles, performance metrics, and other characteristics that make each one unique.
This is an incredible achievement for a company that is young compared to what it goes up against. When Tesla entered the automotive market, Ford, GM, and Stellantis widely dominated the playing field. Since then, Tesla has caused such a disruption that these three massive brands had to scramble to create EV projects of their own.
Despite their best efforts, they have not been able to match the prowess or the effectiveness of Tesla. They are all reliant on Tesla’s charging infrastructure, their software is inferior, and their self-driving projects are elementary in comparison.
Tesla felt its fair share of growing pains over the years as well. As recent at 2019, there were complaints about build quality, paint quality, and overall luxuriousness. These things have all been improved upon through the company’s maturity, and these strides in quality have led to this 10 million vehicle production achievement, something that other small-and-scrappy EV makers will hope to accomplish one day.
SpaceX just picked up another $1.6 billion from the Pentagon, with the U.S. Space Force awarding two task orders worth $1.6 billion to fly 18 Falcon 9 missions from Vandenberg Space Force Base in California through the end of 2027. The launches will carry satellites for the Space Based Sensing and Targeting portfolio, a set of programs meant to help the military detect and track airborne threats and relay that information across forces in near real time.
The award falls under National Security Space Launch Phase 3 Lane 1, the Space Force’s faster, commercial style procurement track for missions that do not require the military’s most demanding certification process. It is also the largest single order publicly disclosed under that program so far, and the first task order issued since the Space Force nearly tripled Lane 1’s contract ceiling from $5.6 billion to $17 billion on July 17.
SpaceX to become America’s Military data backbone for missiles, drones, and warfighters
Eric Zarybnisky, the Space Force’s acting portfolio acquisition executive for space access, said the entire process, from identifying the requirement to signing the contract, took about two months, including a month set aside for companies to prepare proposals.
SpaceX is not just launching these satellites. It already holds the contracts to build two of the programs within the same portfolio, $4.16 billion for the Space Based Airborne Moving Target Indicator system and $2.29 billion for the Space Data Network Backbone, which Teslarati covered in May. That means SpaceX is now responsible for both building key pieces of the military’s next generation sensing network and getting them into orbit.
With this latest award, SpaceX’s Pentagon contract total for 2026 alone tops $8 billion, adding to a defense portfolio that already includes the Golden Dome missile defense software group SpaceX joined in April and a string of GPS launches it inherited after ULA’s Vulcan rocket ran into a booster anomaly, which we detailed in March.
Lane 1’s vendor pool technically includes seven companies: SpaceX, ULA, Blue Origin, Rocket Lab, Stoke Space, Impulse Space, and Relativity Space. In practice, SpaceX remains the only provider with the combination of launch cadence, flight proven Falcon 9 hardware, and West Coast infrastructure to support a campaign requiring roughly one Vandenberg launch a month for the next year and a half.
Some lawmakers have flagged the growing concentration of national security launches with one company as a risk worth watching. For now, the Space Force keeps backing SpaceX, with it being the company that shows up ready to launch.
