SpaceX assembles world’s largest rocket with giant robot arms

Published

on

For the second time ever, SpaceX has fully stacked a two-stage Starship rocket, once again creating the largest launch vehicle prototype ever assembled.

This time around, though, SpaceX used building-sized arms installed on Starbase’s ~145-meter-tall (~480 ft) ‘launch tower’ to lift to grapple Starship, lift massive upper stage more than 80 meters (260 ft) off the ground, and lower on top of a Super Heavy booster. After multiple days of apparent troubleshooting and false-starts and weeks of proof-testing with water bags weighing dozens to hundreds of tons, the giant robot seemed to perform perfectly, pausing only once during the ascent.

After holding Starship S20’s weight for about an hour and attaching two smaller stabilization arms to the side of the rocket, the Mechazilla arms began to lift Starship in earnest around 10:27 pm CST. Around 10:45 pm, with the tip of Starship S20’s nose just shy of the top of the launch tower, the lift reached its apogee – multiple SpaceX drones swarming the rocket to document the milestone.

At their peak, the tower’s arms then swung Starship about 45 degrees until it was directly above Super Heavy Booster 4’s interstage. The launch tower’s Starship quick-disconnect (QD) arm – responsible for connecting the upper stage to ground systems – then swung in, partially deploying and ‘grabbing’ Super Heavy to fully stabilize the booster. Finally, once the booster was secured and SpaceX was confident in the alignment of the two massive rocket stages, the tower arms carefully lowered Starship onto Super Heavy’s interstage, where several clamps grabbed onto the ship to fully mate the pair.

While the actual near-term utility of those arms remains ambiguous at best, their first successful use is an undeniably impressive technical achievement. SpaceX began assembling them less than nine months ago, beginning with the Starship QD arm around May 2021. SpaceX began installing the two main Mechazilla arms in October 2021, three months after assembly began. Just three months after that, all three have come together for the first time to lift and stack the world’s largest rocket.

Perhaps most impressive of all is that on the very first try, lifting Starship and stacking it on top of Super Heavy with the launch and integration tower took just three hours from the start of the lift to a fully mated rocket. Additionally, though SpaceX did get lucky with minimal wind, it’s also impressive just how little uncontrolled movement was visible as Starship hung in the air hundreds of feet above the ground. Virtually no swaying was visible, meaning that the arms were doing their job of stabilizing the massive rockets in a situation where even a gentle breeze could make stacking Starship with a crane far too risky.

CEO Elon Musk will now have one of the most impressive accomplishments in modern spaceflight as a backdrop when he presents an update on the same rocket, hopefully shedding light on Starship’s next steps and the roles Ship 20 and Booster 4 might play in them. Stay tuned for updates on the event, which is scheduled to begin no earlier than 8pm CST, February 10th (02:00 UTC 11 Feb).

California hits Tesla Cybercab and Robotaxi driverless cars with new law

California just gave police power to ticket driverless cars, including Tesla’s Cybercab fleet.

California DMV formally adopted new rules on April 29, 2026 that allow law enforcement to issue “notices of noncompliance”, or in other words, ticket autonomous vehicle companies when their cars commit moving violations. The rules take effect July 1, 2026, officially closes a regulatory gap that previously let driverless cars operate on public roads with nearly no traffic enforcement consequences.

Until now, state traffic law only applied to human “drivers,” which meant that when no person was behind the wheel, police had no mechanism to issue a ticket. Officers were limited to citing driverless vehicles for parking violations only. A well-known example came in September 2025, when a San Bruno officer watched a Waymo robotaxi execute an illegal U-turn and could do nothing but notify the company.

Under the new framework, when an officer observes a violation, the autonomous vehicle company is effectively treated as the driver. Companies must report each incident to the DMV within 72 hours, or 24 hours if a collision is involved. Repeated violations can result in fleet size restrictions, operational suspensions, or full permit revocation. Local officials also gained new authority to geofence driverless vehicles out of active emergency zones within two minutes and require a live emergency response line answered within 30 seconds.

Tesla Cybercab ramps Robotaxi public street testing as vehicle enters mass production queue

California’s new enforcement rules arrive at a pivotal moment for Tesla. The company is ramping Cybercab production at Giga Texas toward hundreds of units per week, targeting at least 2 million units annually at full capacity, while simultaneously pushing to expand its Robotaxi service to dozens of U.S. cities by end of 2026. Unsupervised FSD for consumer vehicles is currently targeted for Q4 2026, and when it arrives, Tesla’s fleet may not have a human to absorb legal accountability, under the July 1 rules.

Tesla has confirmed plans to expand its Robotaxi service to seven new cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas, with the service already running without safety drivers in Austin. Musk has said he expects robotaxis to cover between a quarter and half of the United States by end of year.

Tesla Model X shocks everyone by crushing every other used car in America

The Model X is one of Tesla’s flagship models, the other being the Model S. Earlier this year, Tesla confirmed it would discontinue production of both the Model S and Model X to make way for Optimus robot production at the Fremont Factory in Northern California.

The Tesla Model X was the fastest-selling used vehicle in the United States in the first quarter of the year, crushing every other used car in America.

iSeeCars data for the first quarter shows that the Model X was the fastest-selling used car, lasting just 25.6 days on the market on average, two days better than that of the second-place Lexus RX 350h. The Cybertruck, Model Y, and Model S, in seventh, ninth, and thirteenth place, respectively, also made the list.

The Model X is one of Tesla’s flagship models, the other being the Model S. Earlier this year, Tesla confirmed it would discontinue production of both the Model S and Model X to make way for Optimus robot production at the Fremont Factory in Northern California.

Tesla brings closure to flagship ‘sentimental’ models, Musk confirms

Bringing closure to these two vehicles signaled the end of the road for the cars that have effectively built Tesla’s reputation for luxury and high-end passenger vehicles.

Relying on the sales of its mass market Model Y and Model 3, as well as leaning on the success of future products like the Cybercab, is the angle Tesla has chosen to take.

Teslas are also performing extremely well as a whole on the resale market. iSeeCars data shows that, “while the average price of a 1- to 5-year-old non-Tesla EV fell 10.3% in Q1 2026 year-over-year, the average price of a used Tesla was essentially flat at 0.1% lower across the same period. Traditional gas car prices dropped 2.8% during this same period.”

Additionally, market share for gas cars has dropped nearly 3 percent since the same quarter last year. Tesla has remained level, while the non-Tesla EV market share has increased 30 percent, mostly due to more models available.

Nevertheless, those non-Tesla EVs have seen their value drop by over 10 percent, while Tesla’s values have remained level.

Executive Analyst Karl Brauer said:

“Used electric vehicles without a Tesla badge have lost more than 10% of their value in the past year. This compares to stable values for Teslas and hybrids, and a modest 2.8% drop for traditional gasoline vehicles.”

Teslas, as well as non-luxury hybrids, are displaying the strongest resistance in the face of faltering demand, the publication says. But the more impressive performance is that of the Model X alone.

Tesla’s decision to stop production of the Model X may have played some part in the vehicle’s pristine performance in Q1. With the car already placed at a premium price point, used models are already more appealing to consumers. Perhaps second-hand versions were more than enough for those who wanted a Model X, and only a Model X.

Tesla Cybertruck’s head-scratching trim sold terribly, recall documents reveal

After Tesla decided to build a Rear-Wheel-Drive Cybertruck trim back in 2025, which was void of many features and only featured a small discount.

The head-scratching offering was only available for a few months, and evidently, it did not sell very well, which we all suspected. New recall documents on the vehicle from the National Highway Traffic Safety Administration (NHTSA) now reveal just how poorly it sold.

The recall deals with a potentially separating wheel stud and potentially impacts 173 Cybertruck units with the 18-inch steel wheels. The Cybertruck RWD was the only trim level to feature these, and the 173 potentially impacted units represent a portion of the population of pickups. Therefore, it’s not the entire number of RWD Cybertruck sold, but it could show how little interest it gathered.

The NHTSA document states:

“On affected vehicles, higher severity road perturbations and cornering may strain the stud hole in the wheel rotor, causing cracks to form. If cracking propagates with continued use and strain, the wheel stud could eventually separate from the wheel hub.”

Only 5 percent are expected to be impacted, meaning less than 10 units will have the issue if the NHTSA and Tesla estimates are correct. Nevertheless, the true story here is how terribly the RWD Cybertruck sold.

Tesla ended production and stopped offering the RWD Cybertruck to customers last September. For just $10,000 less than the All-Wheel-Drive trim, Tesla offered the RWD Cybertruck with just one motor, textile seats instead of leather, only 7 speakers instead of 15, no Rear Touchscreen, no Powered Tonneau Cover for the truck bed, and no 120v/240v outlets.

For just $10,000 more, at $79,990, owners could have received all of those premium features, as well as a more capable All-Wheel-Drive powertrain that featured Adaptive Air Suspension. The discount simply was not worth the sacrifices.

Orders were few and far between, and sources told us that when it was offered, sales were extremely tempered because customers could not see the value in this trim level.

Even Tesla’s most loyal supporters thought the offering was kind of a joke, and the $10,000 extra was simply worth it.
