SpaceX’s rocket-catching ‘Mechazilla’ arms are almost ready to join Starship launch tower
Update: SpaceX has now lifted, flipped, and staged all three components of Starbase’s Mechazilla rocket-catcher, including two giant arms measuring some 36m (~120 ft) from tip to tower.
Currently hanging from both of SpaceX’s largest Starbase cranes, teams must now install massive steel pins to turn those three separate components – two arms and a carriage-like base – into an integrated structure ready for installation on the exterior of the first Starship launch tower. It’s unclear how long that might take but SpaceX is wasting no time and has already begun installing 12 ‘guide blocks’ that will allow the carriage and arms to slide up and down tracks affixed to three of four tower ‘legs.’
SpaceX has begun preparing its Starbase ‘launch tower’ for the installation of a pair of giant arms designed to lift, stack, and even catch Starships and Super Heavy boosters out of mid-air.
Deemed ‘Mechazilla’ by CEO Elon Musk, assembly of first of the structure’s three main arms only began in earnest in June 2021. That ‘quick disconnect’ (QD) arm – designed to fuel Starship and stabilize Super Heavy during Starship stacking – was installed on August 29th and followed by the addition of a claw-like appendage meant to grab onto boosters about a month later. Now, all that’s missing from Mechazilla’s first arm is the actual ‘quick-disconnect’ device that will connect to Starship’s umbilical panel to supply propellant, power, and communications links.
However, ever since Musk first hinted at the possibility of catching Super Heavy and Starship, the star of the Mechazilla show has always been its ‘chopsticks’ – SpaceX’s internal colloquialism for the pair of giant, moving arms meant to lift and catch rockets.
Prefabricated catch arm parts began to arrive at Starbase less than three months ago in the last week or two of July. Just a month later, the basic structure of both arms was practically complete, leaving another month for plumbing, wiring, and a number of smaller structural additions. Less than three months after the first parts arrived SpaceX lifted the catch arm ‘carriage’ – a sort of backbone that will hold both arms and attach to the launch tower – vertical to install it on a temporary jig.
Two days later, SpaceX lifted and flipped the first catch arm into the correct orientation with Starbase’s largest crane. To install both arms, though, it appears that SpaceX will need to have a second crane simultaneously lift and flip the second arm and move it into position so that a single giant steel pin can slot through both of their hinges. Perhaps because of the arrival of high winds on Sunday, the first (right) arm continues to hang from a crane just a few feet away from the arm carriage it will eventually be installed on, while the left arm has yet to move towards a second crane recently staged to lift it.
Ultimately, though, SpaceX is clearly ready to install both arms on the tower carriage. Once that process is complete, it appears that SpaceX will finish some minor carriage outfitting tasks before eventually installing the assembled carriage-and-arms structure onto the launch tower itself. It’s hard to say for sure but depending on the readiness of the complex system of pulleys and draw-works the tower needs to hold and move the carriage and arms, Mechazilla could effectively be fully installed and ready for testing by the end of the month. Stay tuned!

SpaceX Starship Version 3 booster crumples in early testing
Photos of the incident’s aftermath suggest that Booster 18 will likely be retired.
SpaceX’s new Starship first-stage booster, Booster 18, suffered major damage early Friday during its first round of testing in Starbase, Texas, just one day after rolling out of the factory.
Based on videos of the incident, the lower section of the rocket booster appeared to crumple during a pressurization test. Photos of the incident’s aftermath suggest that Booster 18 will likely be retired.
Booster test failure
SpaceX began structural and propellant-system verification tests on Booster 18 Thursday night at the Massey’s Test Site, only a few miles from Starbase’s production facilities, as noted in an Ars Technica report. At 4:04 a.m. CT on Friday, a livestream from LabPadre Space captured the booster’s lower half experiencing a sudden destructive event around its liquid oxygen tank section. Post-incident images, shared on X by @StarshipGazer, showed notable deformation in the booster’s lower structure.
Neither SpaceX nor Elon Musk had commented as of Friday morning, but the vehicle’s condition suggests it is likely a complete loss. This is quite unfortunate, as Booster 18 is already part of the Starship V3 program, which includes design fixes and upgrades intended to improve reliability. While SpaceX maintains a rather rapid Starship production line in Starbase, Booster 18 was generally expected to validate the improvements implemented in the V3 program.
Tight deadlines
SpaceX needs Starship boosters and upper stages to begin demonstrating rapid reuse, tower catches, and early operational Starlink missions over the next two years. More critically, NASA’s Artemis program depends on an on-orbit refueling test in the second half of 2026, a requirement for the vehicle’s expected crewed lunar landing around 2028.
While SpaceX is known for diagnosing failures quickly and returning to testing at unmatched speed, losing the newest-generation booster at the very start of its campaign highlights the immense challenge involved in scaling Starship into a reliable, high-cadence launch system. SpaceX, however, is known for getting things done quickly, so it would not be a surprise if the company manages to figure out what happened to Booster 18 in the near future.

Tesla FSD (Supervised) is about to go on “widespread” release
In a comment last October, Elon Musk stated that FSD V14.2 is “for widespread use.”
Tesla has begun rolling out Full Self-Driving (Supervised) V14.2, and with this, the wide release of the system could very well begin.
The update introduces a new high-resolution vision encoder, expanded emergency-vehicle handling, smarter routing, new parking options, and more refined driving behavior, among other improvements.
FSD V14.2 improvements
FSD (Supervised) V14.2’s release notes highlight a fully upgraded neural-network vision encoder capable of reading higher-resolution features, giving the system improved awareness of emergency vehicles, road obstacles, and even human gestures. Tesla also expanded its emergency-vehicle protocols, adding controlled pull-overs and yielding behavior for police cars, fire trucks, and ambulances, among others.
A deeper integration of navigation and routing into the vision network now allows the system to respond to blocked roads or detours in real time. The update also enhances decision-making in several complex scenarios, including unprotected turns, lane changes, vehicle cut-ins, and interactions with school buses. All in all, these improvements should help FSD (Supervised) V14.2 perform in a very smooth and comfortable manner.
Elon Musk’s predicted wide release
The significance of V14.2 grows when paired with Elon Musk’s comments from October. While responding to FSD tester AI DRIVR, who praised V14.1.2 for fixing “95% of indecisive lane changes and braking” and who noted that it was time for FSD to go on wide release, Musk stated that “14.2 for widespread use.”
FSD V14 has so far received a substantial amount of positive reviews from Tesla owners, many of whom have stated that the system now drives better than some human drivers as it is confident, cautious, and considerate at the same time. With V14.2 now rolling out, it remains to be seen if the update also makes it to the company’s wide FSD fleet, which is still populated by a large number of HW3 vehicles.

Tesla FSD V14.2 starts rolling out to initial batch of vehicles
It would likely only be a matter of time before FSD V14.2 videos are posted and shared on social media.
Tesla has begun pushing Full Self-Driving (Supervised) v14.2 to its initial batch of vehicles. The update was initially observed by Tesla owners and veteran FSD users on social media platform X on Friday.
So far, reports of the update have been shared by Model Y owners in California whose vehicles are equipped with the company’s AI4 hardware, though it would not be surprising if more Tesla owners across the country receive the update as well.
Based on the release notes of the update, key improvements in FSD V14.2 include a revamped neural network for better detection of emergency vehicles, obstacles, and human gestures, as well as options to select arrival spots.
It would likely only be a matter of time before FSD V14.2 videos are posted and shared on social media.
Following are the release notes of FSD (Supervised) V14.2, as shared on X by longtime FSD tester Whole Mars Catalog.
