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 flexed one incredible Robotaxi metric during the Q2 Earnings Call that skeptics have to hate to hear. The company’s platform has already driven more than 380,000 miles of unsupervised ride-hailing across several states with no notable incidents.
During the company’s Q2 Earnings Call on Wednesday, Vice President of AI, Ashok Elluswamy, said:
“First of all, I’d like to state that the Robotaxi program has been operating extremely well. Especially in terms of safety, the program has had an impeccable safety record. We have driven more than 380,000 miles of unsupervised Robotaxi, now across six cities in two different states. We have had zero notable incidents. Any reports have been of other actors impacting us when we were stationary. I like to emphasize how safe the operation has been so far. Zero notable incidents over 380,000 miles.”
Elluswamy’s claim over Robotaxi miles is a significant milestone for Tesla in the grand scheme, especially considering this is a sizeable number of miles without any incident.

Tesla’s self-driving approach is much different than that of other companies. Tesla has maintained that vision is the only thing needed to have a solid and effective self-driving suite. Many self-driving companies utilize things like LiDAR, sensors, and other elements to improve performance, but Elluswamy sent a jab at those who believe it’s needed.
“Historically, the so-called experts have always claimed that you need LiDARs, radars, HD maps, and the entire kitchen sink to drive safely. Here we show that such is not true. You can have safe, comfortable, and affordable autonomy with just cameras. This record should be a huge validation of Tesla’s entire AI approach.”
The feat of accumulating this many miles without any driver behind the wheel is impressive. The thing is, Tesla is also doing this across several different locations, with varying traffic rules, pedestrian levels, weather patterns, and other important factors.
While Tesla is not ready to roll out an unsupervised platform completely, it is a slow but steady indication that the company is well on its way to figuring things out.
The company’s attitude toward expansion is slow, safe, and controlled, and despite this huge milestone, it will still be some time until we see Tesla truly unleash unsupervised rides more aggressively.

SpaceX Starship just nailed something it’s never done before
SpaceX’s Starship flew successfully Friday, landing both stages and deploying its first Starlink V3 satellites.
Starship’s thirteenth test flight delivered exactly what SpaceX needed with a clean liftoff, two successful stage recoveries, and the first real payload the vehicle has ever carried to space. Booster 20 and Ship 40 lifted off at 5:51 p.m. CT from Starbase, and by the time the mission wrapped roughly an hour later, both halves of the rocket had done exactly what they were supposed to do.
Booster 20 separated from Ship 40 a few minutes into the flight and stuck a controlled splashdown in the Gulf of Mexico about six minutes after liftoff. That is a meaningful turnaround from Flight 12 in May, when the booster lost several engines during its boostback burn before a hard water landing attempt.

Starship 40’s performance was arguably the bigger win. The vehicle deployed the first 20 operational Starlink V3 satellites Starship has ever carried, then flew a suborbital arc to a landing in the Indian Ocean that SpaceX commentator Dan Huot called the company’s softest splashdown yet. “This is a dream scenario for this team that’s trying to get this heat shield data,” Huot said on the live broadcast, according to Space.com’s live coverage. “I’m a little over the moon right now. Wow. Lucky number 13.”
Unlike the mass simulators SpaceX flew on Flight 12, these were production Starlink V3 satellites, meant to extend solar arrays and antennas and attempt to link with the broader constellation before reentering minutes later. Getting real hardware through a full deploy sequence on only the second flight of the V3 generation keeps Starship on schedule for the payload work NASA is counting on for future Artemis lunar landings.
What an awesome launch, really seems like everything went super well and it was all incredibly smooth.

The flight also arrives at a moment when SpaceX needed a win. SPCX has traded below its $135 IPO price since mid-July, as Teslarati reported when the mission slipped to Friday, and short interest has climbed to roughly a third of the tradable float. A clean flight will not fix a balance sheet, but it does answer the one question SpaceX absolutely needed answered this week: whether the fixes made after the July 16 abort would hold up under real flight conditions. They did, on both stages, on the first try after the redesign.
SpaceX has not set a target date for Flight 14, though the company has said it wants to push toward an orbital attempt on the next mission. After Friday, that goal looks a lot more within reach.
Tesla’s Supercharger Diner in Los Angeles dominated the company’s global usage rankings after just one year, proving the concept is more than just a one-off novelty location that will fade away.
The performance could incite the company to build more locations, something that CEO Elon Musk has hinted at for some time.
Tesla’s Supercharger Diner delivered 21.2 GWh of energy in its first year of operation, the company’s head of Charging, Max de Zegher, revealed on X. Of the top 10 most utilized Supercharger locations in Tesla’s global infrastructure, the Diner in Los Angeles was the most used by drivers, and it wasn’t particularly close:
Tesla Diner opened exactly 1 year ago. Inspiring that futuristic places like this exist.
It’s our highest usage Supercharger in the world: 21.2 GWh delivered in a year, 1.6k sessions/day.

On its launch day one year ago, nobody was too sure what the Tesla Diner would be about. It seemed like an interesting concept, and considering it had been in the works for years, it was a highly anticipated launch that many were looking forward to.
Based on its success, we could see additional Diners with Superchargers built throughout the United States, and potentially beyond. Musk has said on several occasions that the company would be willing to bring the Diner idea to more markets.
Tesla makes major change at Supercharger Diner amid epic demand
Of the markets that Musk has mentioned, both Palo Alto and Austin have come to be perceived as ideal selections. However, there are no concrete plans as of now to build new Supercharger Diners anywhere; the location on Santa Monica Boulevard will remain the exclusive spot to pick up Tesla-inspired eats, at least for the time being.
