SpaceX moves Super Heavy booster to make room for Mechazilla arm installation
For the second time, SpaceX has removed the first potentially flightworthy Super Heavy from Starbase’s orbital launch mount – this time to reportedly make room for the installation of a pair of huge ‘Mechazilla’ arms.
Designed with three primary purposes in mind, SpaceX has decided to outfit Starbase’s Starship launch tower – an almost 500 ft (150m) tall framework – with three massive arms that CEO Elon Musk has informally deemed “Mechazilla.” The first of those arms is a relatively simple swinging structure that has already been installed on the tower and outfitted with a giant claw-like appendage. Once a few more parts are installed and a bit more plumbing completed, that “quick disconnect arm” or QD arm will help stabilize Super Heavy during Starship installation and connect the massive reusable upper stage to the pad’s tank farm and power supplies while still on the ground.
The star of the show, though, has always been a pair of even larger arms that are hoped to one day all SpaceX to catch Super Heavy boosters and Starships out of the air.
Of course, those catcher arms – deemed chopsticks by SpaceX employees – have more than one purpose. Likely explaining why they were ever considered in the first place, SpaceX’s Starbase launch site – situated walking distance from the Gulf of Mexico on the South Texas coast – was always going to have to deal with extreme weather and high winds on a practically daily basis. Additionally, conditions that are already disruptive at sea level become a near-constant nightmare for vertical launch vehicle integration, where Starship and Super Heavy are effectively hollow cylinders with extensive surface areas that need to be regularly and precisely manipulated 50-150m (200-450 ft) above the ground.
Already, SpaceX regularly has to halt work involving cranes and boom lifts at Starbase. For Starbase (Boca Chica) to ever be able to support regular orbital Starship launches, let alone the dozens to hundreds per year Musk has hinted at, cranes were never going to be a viable long-term solution for the all-weather capabilities and rapid reusability SpaceX requires. In other words, whether SpaceX ever actually manages to routinely ‘catch’ the world’s largest rocket booster and upper stage in the future, a tower with giant arms (or some other exotic crane-free solution) was always going to be needed at Starbase.
Mauricio, thanks for the shout-out. I got some great feedback from folks and updated this diagram once more. Added another @NicAnsuini photo to show the scale of these parts! pic.twitter.com/o54hdBITfL— LunarCaveman (@LunarCaveman) September 16, 2021
This is all to say that the Starship launch tower’s massive pair of arms – (in)famous for Musk’s plans to catch rockets – have a more immediate and guaranteed purpose: lifting, stacking, and otherwise manipulating Starship and Super Heavy in almost all weather conditions. Using tiny hardpoints located just under Super Heavy’s grid fins and (once installed) under Starship’s forward flaps, the chopstick arms will be mounted on a carriage that will attach to rails installed on the exterior of three of the tower’s arms. A complex system of cables, winches, motors, and pulleys will then attach to that carriage, giving the carriage and its arms the ability to move up and down the tower.
In theory, that means that the launch tower arms will be able to drop down, grab Super Heavy off of a SpaceX transporter, and lift it onto the orbital launch mount. Then, once the quick disconnect arm has swung into place and ‘grabbed’ Super Heavy’s interstage to secure it, the main arms will again drop down, grab Starship off of another transporter, and raise the 50m (~165 ft) rocket around 100m off the ground to install it on top of Super Heavy. Finally, the QD arm can then connect Starship to the pad systems.
SpaceX has been working around the clock on those chopstick arms for months. However, thanks to information shared by a forum member who visited Starbase and briefly chatted with one of the SpaceX technicians on-site, they might be almost finished. According to the employee they spoke with, SpaceX planned to temporarily remove Super Heavy Booster 4 from the orbital launch mount to make room for Mechazilla chopstick arm installation as early as this weekend (now come and gone) or next week. Mere days later, SpaceX returned B4 to a transport stand and moved the booster out of the way. In other words, having already been proven right with Super Heavy, it appears that SpaceX really does intend to install the Starship launch tower’s chopstick arms and carriage as early as this week. Stay tuned for more!
Tesla has officially launched public Robotaxi rides in Austin, Texas, without a Safety Monitor in the vehicle, marking the first time the company has removed anyone from the vehicle other than the rider.
The Safety Monitor has been present in Tesla Robotaxis in Austin since its launch last June, maintaining safety for passengers and other vehicles, and was placed in the passenger’s seat.
Tesla planned to remove the Safety Monitor at the end of 2025, but it was not quite ready to do so. Now, in January, riders are officially reporting that they are able to hail a ride from a Model Y Robotaxi without anyone in the vehicle:

Tesla started testing this internally late last year and had several employees show that they were riding in the vehicle without anyone else there to intervene in case of an emergency.
Tesla has now expanded that program to the public. It is not active in the entire fleet, but there are a “few unsupervised vehicles mixed in with the broader robotaxi fleet with safety monitors,” Ashok Elluswamy said:
Robotaxi rides without any safety monitors are now publicly available in Austin.
Starting with a few unsupervised vehicles mixed in with the broader robotaxi fleet with safety monitors, and the ratio will increase over time. https://t.co/ShMpZjefwB

Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing
The Robotaxi program also operates in the California Bay Area, where the fleet is much larger, but Safety Monitors are placed in the driver’s seat and utilize Full Self-Driving, so it is essentially the same as an Uber driver using a Tesla with FSD.
In Austin, the removal of Safety Monitors marks a substantial achievement for Tesla moving forward. Now that it has enough confidence to remove Safety Monitors from Robotaxis altogether, there are nearly unlimited options for the company in terms of expansion.
While it is hoping to launch the ride-hailing service in more cities across the U.S. this year, this is a much larger development than expansion, at least for now, as it is the first time it is performing driverless rides in Robotaxi anywhere in the world for the public to enjoy.
Tesla has scheduled its Earnings Call for Q4 and Full Year 2025 for next Wednesday, January 28, at 5:30 p.m. EST, and investors are already preparing to get some answers from executives regarding a wide variety of topics.
The company accepts several questions from retail investors through the platform Say, which then allows shareholders to vote on the best questions.
Tesla does not answer anything regarding future product releases, but they are willing to shed light on current timelines, progress of certain projects, and other plans.
There are five questions that range over a variety of topics, including SpaceX, Full Self-Driving, Robotaxi, and Optimus, which are currently in the lead to be asked and potentially answered by Elon Musk and other Tesla executives:
- You once said: Loyalty deserves loyalty. Will long-term Tesla shareholders still be prioritized if SpaceX does an IPO?
- Our Take – With a lot of speculation regarding an incoming SpaceX IPO, Tesla investors, especially long-term ones, should be able to benefit from an early opportunity to purchase shares. This has been discussed endlessly over the past year, and we must be getting close to it.
- When is FSD going to be 100% unsupervised?
- Our Take – Musk said today that this is essentially a solved problem, and it could be available in the U.S. by the end of this year.
- What is the current bottleneck to increase Robotaxi deployment & personal use unsupervised FSD? The safety/performance of the most recent models or people to monitor robots, robotaxis, in-car, or remotely? Or something else?
- Our Take – The bottleneck seems to be based on data, which Musk said Tesla needs 10 billion miles of data to achieve unsupervised FSD. Once that happens, regulatory issues will be what hold things up from moving forward.
- Regarding Optimus, could you share the current number of units deployed in Tesla factories and actively performing production tasks? What specific roles or operations are they handling, and how has their integration impacted factory efficiency or output?
- Our Take – Optimus is going to have a larger role in factories moving forward, and later this year, they will have larger responsibilities.
- Can you please tie purchased FSD to our owner accounts vs. locked to the car? This will help us enjoy it in any Tesla we drive/buy and reward us for hanging in so long, some of us since 2017.
- Our Take – This is a good one and should get us some additional information on the FSD transfer plans and Subscription-only model that Tesla will adopt soon.
Tesla will have its Earnings Call on Wednesday, January 28.
Elon Musk shared an incredible detail about Tesla Cybercab’s potential efficiency, as the company has hinted in the past that it could be one of the most affordable vehicles to operate from a per-mile basis.
ARK Invest released a report recently that shed some light on the potential incremental cost per mile of various Robotaxis that will be available on the market in the coming years.
The Cybercab, which is detailed for the year 2030, has an exceptionally low cost of operation, which is something Tesla revealed when it unveiled the vehicle a year and a half ago at the “We, Robot” event in Los Angeles.
Musk said on numerous occasions that Tesla plans to hit the $0.20 cents per mile mark with the Cybercab, describing a “clear path” to achieving that figure and emphasizing it is the “full considered” cost, which would include energy, maintenance, cleaning, depreciation, and insurance.
Probably true
— Elon Musk (@elonmusk) January 22, 2026
ARK’s report showed that the Cybercab would be roughly half the cost of the Waymo 6th Gen Robotaxi in 2030, as that would come in at around $0.40 per mile all in. Cybercab, at scale, would be at $0.20.

This would be a dramatic decrease in the cost of operation for Tesla, and the savings would then be passed on to customers who choose to utilize the ride-sharing service for their own transportation needs.
The U.S. average cost of new vehicle ownership is about $0.77 per mile, according to AAA. Meanwhile, Uber and Lyft rideshares often cost between $1 and $4 per mile, while Waymo can cost between $0.60 and $1 or more per mile, according to some estimates.
Tesla’s engineering has been the true driver of these cost efficiencies, and its focus on creating a vehicle that is as cost-effective to operate as possible is truly going to pay off as the vehicle begins to scale. Tesla wants to get the Cybercab to about 5.5-6 miles per kWh, which has been discussed with prototypes.
Additionally, fewer parts due to the umboxed manufacturing process, a lower initial cost, and eliminating the need to pay humans for their labor would also contribute to a cheaper operational cost overall. While aspirational, all of the ingredients for this to be a real goal are there.
It may take some time as Tesla needs to hammer the manufacturing processes, and Musk has said there will be growing pains early. This week, he said regarding the early production efforts:
“…initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast.”
