SpaceX installs first ‘Mechazilla’ arm on Starship launch tower
One month after SpaceX stacked Starship’s South Texas ‘launch tower’ to its full height, the company has installed the first arm on what amounts to the backbone of ‘Mechazilla.’
At the end of July, after less than four months of work, a team of SpaceX workers and contractors installed the final prefabricated section of a ~145m (~475 ft) tall tower meant to support orbital Starship launches. Above all else, SpaceX’s first custom-built ‘launch tower’ is a sort of backbone or anchor point for several massive, mechanical arms that will accomplish the actual tasks of servicing – and, perhaps, catching – Starships and Super Heavy boosters.
Work on all three of the arms expected to make up what SpaceX CEO Elon Musk has described as “Mechazilla” has been visibly underway since the last week of June as a small army of welders carefully assembled dozens of sections of heavy-duty steel pipe into house-sized frames. Almost exactly two months later, SpaceX has installed the first of those three arms on the exterior of Starship’s skyscraper-sized launch tower.
Known as the tower’s quick-disconnect or QD swing arm, the standalone structure is reportedly designed to accomplish a few different tasks. First, as its unofficial name might suggest, the QD arm will hold a quick-disconnect umbilical connector that will temporarily attach to the base of Starships to load them with fuel, oxidizer, and other consumables and link them to ground power and networking. For years, it appeared that SpaceX planned to fuel Starship upper stages through their Super Heavy boosters, which will themselves be connected to umbilical panels on a table-like launch mount that sits beside the tower.
However, once work began on Starship S20, the first potentially space-capable prototype, it was clear that SpaceX had foregone the umbilical plate normally installed at the base of Starship skirts and moved that connection to the ship’s lower back. Musk later confirmed as much in interviews and tweets, revealing that longstanding plans to dock Starships aft to aft for in-space refueling were also up in the air. As of late, aside from reiterating that the launch pad itself (“Stage Zero,” per Musk) is even more complex and difficult than Starship or Super Heavy, SpaceX’s CEO has also repeatedly stated a desire to offload as many systems as possible onto the launch pad – seemingly regardless of the complexity of the alternative.
Enter the building-sized robot informally known as Mechazilla. While the relatively simple swinging ‘QD arm’ that will fuel Starship and stabilize both stages of the rocket is a common feature of rockets and launch pads, the only experience SpaceX itself has with umbilical swing arms is the Crew Access Arm (CAA) that allows astronauts and cargo to board Dragon spacecraft after Falcon 9 goes vertical – a structure with near-zero umbilical utility. Technically, the transporter/erectors (T/Es) that cradle Falcon rockets, lift them vertical, and fuel them before launch have some similarities with swing arms but SpaceX has always used simpler and more reliable passive mechanisms whenever possible.
A step further, though, SpaceX has also seemingly foregone the installation of a basic crane on top of its Starship tower and Musk himself has developed an almost infamous aversion to the inclusion of something as seemingly simple as landing legs on Super Heavy boosters – and, eventually, perhaps even (some) Starship variants. Instead of adding rudimentary legs to Super Heavy prototypes, Musk has seemingly pushed SpaceX to turn Starship’s launch tower into a complex, vulnerable, and fragile rocket recovery system. Beyond the comparatively mundane QD arm, Musk says that SpaceX will ultimately install a pair of massive house-sized steel arms mounted on a sort of external elevator. Those arms will apparently be capable of actuating and moving up and down the tower with the speed, precision, and reliability needed to quite literally catch Super Heavy boosters – and, eventually, Starships – out of mid-air.
The team tasked with designing and building those rocket-catching arms have affectionately deemed them “chopsticks” – a nod towards the kind of nuanced actuation they’ll need to recover the world’s largest rocket boosters and upper stages without missing or destroying them. Having really only just perfected propulsive vertical landing with Falcon 9 and Falcon Heavy boosters, SpaceX thus intends to throw a few extra points of failure into the mix.
To SpaceX and Musk’s credit, whether the company’s second attempt at catching rockets goes as well as the first, some version of the massive ‘chopstick’ arms SpaceX is working on was likely going to be necessary just to rapidly turn around boosters and Starships – and do so regardless (within reason) of weather conditions. By replacing a tower crane with giant arms, SpaceX will hopefully be able to stack Starship on Super Heavy (and Super Heavy on the launch mount) even in the high winds that are almost always present on the South Texas Gulf Coast. If SpaceX can also reliably catch boosters with those arms, it could be a significant upgrade for the operations side of Starship reusability. For now, though, only time will tell.

Elon Musk says Tesla is developing a new vehicle: ‘Way cooler than a minivan’
It sounds as if Tesla could be considering a new vehicle to fit the mold of what a larger family would need, and as fans have been demanding it for several years and the company is phasing out the Model X, its only family-geared vehicle, it sounds as if it could be the perfect time.
Tesla CEO Elon Musk said the company is developing a new vehicle, and it will be “way cooler than a minivan.”
It sounds as if Tesla could be considering a new vehicle to fit the mold of what a larger family would need, and as fans have been demanding it for several years and the company is phasing out the Model X, its only family-geared vehicle, it sounds as if it could be the perfect time.
There are a handful of things Musk could be talking about, and as many Tesla owners have wanted a vehicle along the lines of a minivan for hauling around their family, speculation has persisted about what the company would do in terms of developing something for that exact use case.
There were several options, and some of them seemed to be already available. Musk posted on X yesterday that the Cybertruck has three sets of isofix attachments and could fit three child seats or three adults, and it seemed to be a way to deflect plans for a new, larger vehicle as a Model Y L appeared to be present at Giga Texas.
There is also the Robovan, the large people mover that Tesla unveiled at the “We, Robot” back in 2024.
Something way cooler than a minivan is coming

However, it seems Tesla could be developing something like a CyberSUV, something that is going to be large enough to haul around a car full of kids, but could be developed with the company’s aesthetic of the company’s most recent releases: this would likely include a light bar and a more sleek, futuristic look.
We’ve mocked up some potential looks for Tesla’s speculative vehicle in the past:
Tesla has teased the potential of a CyberSUV in the past, showing off clay models that it developed back in September in a teaser video called “Sustainable Abundance.”
Fans and owners have been calling for this development for a very long time, and it seems like Tesla might be ready to finally answer the call on a large SUV. With the segment being dominated by combustion engine vehicles, Tesla could truly disrupt the large SUVs that have been mainstays.
The Chevrolet Tahoe and GMC Yukon would feel some additional pressure, and it would be possible for Tesla to infiltrate some of those sales and pull consumers to electric powertrains.
As the Model S and Model X sunset process is truly hitting full swing, it might be time to consider Tesla’s next option in terms of vehicle development.

Elon Musk’s $10 Trillion robot: Inside Tesla’s push to mass produce Optimus
Tesla’s surging Optimus job listings reveal a company sprinting from prototype to one million robot production.
Tesla is accelerating its push to bring the Optimus humanoid robot to high volume production, and its recent job listings tells the story as clearly as any earnings call.
With well over 100 Optimus related job openings now posted across its U.S. facilities, Tesla is signaling a critical pivot for the program, moving it from a captivating tech demo to a serious manufacturing endeavor. Roles span the full spectrum of the product lifecycle, from Robotics Software Engineers and Manufacturing Engineers to Mechanical Integration Engineers and AI Engineers focused on world modeling and video generation. One active listing for a Software Engineer on the Optimus team asks candidates to build scalable and reliable data pipelines for Optimus manufacturing lines and develop automation tools that accelerate analysis and visualization for mass manufacturing.
Tesla is racing toward a one million unit annual production target. The clearest signal yet that Tesla is treating Optimus as its primary business came on January 28, 2026, during the company’s Q4 2025 earnings call. Musk announced that Tesla is ending production of the Model S and Model X, and will repurpose those lines at its Fremont, California factory to build Optimus humanoid robots.
A production intent prototype of Optimus Version 3 is planned to be ready in early 2026, after which Tesla intends to build a one million unit production line with a targeted production start by the end of 2026. To support that ramp, Tesla broke ground on a massive new Optimus manufacturing facility at Gigafactory Texas in late 2025, with ambitions to eventually reach 10 million units per year.
Tesla Giga Texas to feature massive Optimus V4 production line
The business case for scaling this aggressively is rooted in labor economics. Musk has stated that “Optimus has the potential to be the biggest product of all time,” reasoning that if Tesla can produce capable humanoid robots at scale and reasonable cost, every task currently performed by human labor becomes a potential application. In a separate statement, Musk framed Optimus’s long term importance even more bluntly, saying it could surpass Tesla’s vehicle business in scale with the potential to generate $10 trillion in revenue.
The industries Tesla is targeting first are those most burdened by repetitive physical labor. Early applications include manufacturing assembly, material handling and quality inspection, as well as logistics tasks like loading, unloading, sorting, and transporting goods in warehouses and distribution centers. Longer term, Tesla’s vision is for Optimus to penetrate household, medical, and logistics scenarios at the scale of a smartphone rollout.

Tesla officially begins sunset of Model S and Model X
In the latest move to show Tesla is planning to eliminate the Model S and Model X from production, the company’s Korean arm has officially set a firm cutoff date of March 31, 2026, for new orders of both models.
Tesla has officially started its process of sunsetting the Model S and Model X just months after the company confirmed it would stop producing the two flagship vehicles in 2026.
This step marks the end of an era for the vehicles that helped establish not only Tesla’s prowess as an automaker but also its status as a disruptor in the entire car industry. While these two cars have done a tremendous amount for Tesla, the signal that it is time to wind down their production has evidently arrived.
In the latest move to show Tesla is planning to eliminate the Model S and Model X from production, the company’s Korean arm has officially set a firm cutoff date of March 31, 2026, for new orders of both models.
This is the first time Tesla has announced a hard global deadline for the Model S and X, as after that date, only existing inventory will be available in South Korea.
The move to bring closure to the Model S and Model X aligns with CEO Elon Musk’s plans for Tesla moving forward. During the Q4 2025 Earnings Call in January, Musk said the two cars deserved an “honorable discharge” for what they have done for the company.
The long-running programs are primarily being removed so that manufacturing lines can be repurposed for high-volume manufacturing of the Optimus humanoid robot. Tesla is targeting a production rate of up to one million units each year.
The Model S and Model X being removed from Tesla’s plans is a tough choice, but it was one that was written on the wall. Sales of these premium models have declined sharply in recent years, and even with Plaid configurations that are performance-forward, the company still has had trouble getting them sold.
In 2025, the Model S and Model X together accounted for roughly 3 percent of Tesla’s global deliveries, down significantly from prior periods as competition intensified in the luxury EV segment and buyers shifted toward more affordable options like the Model 3 and Model Y.
The Model S saw sales drop over 50 percent year-over-year in some quarters, while the Model X faced similar pressures from rivals, including the Rivian R1S and BMW iX.
Despite their dwindling volume, the Model S and Model X remain technological showcases. The Plaid variants deliver blistering acceleration, advanced Full Self-Driving capability, and luxurious interiors.
The phase-out paves the way for Tesla’s strategic pivot toward autonomy, robotics, and higher-volume vehicles.
Tesla brings closure to flagship ‘sentimental’ models, Musk confirms
Fremont will continue producing the refreshed Model 3 and Model Y, ensuring the factory remains a key automotive hub while expanding into robotics. Tesla has stated that the shift is not expected to result in job losses and could increase headcount as Optimus production ramps up.
For Tesla fans, the sunset represents a bittersweet moment. The Model S, introduced in 2012, proved EVs could compete with luxury sedans, while the Falcon-wing-door Model X set new standards for family haulers. Owners can expect continued software support and service for years to come.
Many fans have pushed for the Model X to hang around due to its appeal for families.
With the two cars heading out, Tesla’s priority now becomes its future products, especially that of the Optimus robot, which is the main reason for the S/X platform’s conclusion.
