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 Robotaxi appears to be heading to a new U.S. city
Things are expanding for Robotaxi, but the big sign that it is really moving along greatly will be with the expansion to a new city. Tesla has not gone outside of Austin or the Bay Area as of yet, and launching in a new city will be a great indicator of progress.
Tesla Robotaxi appears to be heading to a new U.S. city, and although the company has revealed plans to launch in six new metros this year, it has yet to establish a new location outside of Austin and the Bay Area of California, where it has operated since last Summer.
A lot full of Model Y vehicles was spotted in Henderson, a town just north of Las Vegas, but there seems to be more than just this hint indicating that the Sin City will be the next location to offer potentially driverless rides in a Tesla using its Full Self-Driving suite.
These Model Ys are not your typical vehicles, as they are fitted with hardware that is only on Robotaxis: a rear camera washer is the dead giveaway:
🚨 These rear camera washers are only present on Robotaxi vehicles
Maybe Las Vegas is the next city to get the Robotaxi suite 😀 https://t.co/my3da5L4zc pic.twitter.com/jYFQuX1j2E

The photos and video of the lot were taken by TheZacher on X, who spotted the Model Y fleet in the Henderson parking lot.
The rear camera washer is the main piece of evidence here that indicates Tesla could be looking to expand Robotaxi to Las Vegas, a major ride-hailing hot spot, as it is one of the biggest tourist attractions in the United States. Ride-sharing is a major industry in Vegas, especially for those who are staying off the Strip.
Tesla has also been extremely transparent that Vegas is on its radar for the Robotaxi fleet, as it revealed last year that it was one of five new U.S. cities that it planned to launch the ride-hailing service in this year.
Tesla confirms Robotaxi is heading to five new cities in the U.S.
The others were Phoenix, Dallas, Houston, and Miami.
Things are expanding for Robotaxi, but the big sign that it is really moving along greatly will be with the expansion to a new city. Tesla has not gone outside of Austin or the Bay Area as of yet, and launching in a new city will be a great indicator of progress.
It will also give Tesla a new benchmark against rival company Waymo, which has operated in Las Vegas for some time.

Tesla Roadster gets new unveiling date once again
Musk announced last year that the unveiling, which initially happened back in 2018, would take place on April Fool’s Day. Initial deliveries at the 2018 event were slotted for 2020, but delays in the project, as well as prioritization of other things, continued to push the Roadster back.
The Tesla Roadster is perhaps the most anticipated vehicle in the company’s history, but those who have been waiting anxiously for it will have to push their timelines back once again.
Tesla CEO Elon Musk has revealed that the company is once again pushing back the unveiling event that was originally planned for April 1. It will now take place “probably in late April.”
True.

Musk announced last year that the unveiling, which initially happened back in 2018, would take place on April Fool’s Day. Initial deliveries at the 2018 event were slotted for 2020, but delays in the project, as well as prioritization of other things, continued to push the Roadster back.
There has been so much hype about the Roadster that people are right to be excited about the prospect of its existence.
Musk’s most recent rumblings about the vehicle came last Fall, when he appeared on the Joe Rogan Experience podcast, where he once again hinted the car would be able to hover for a short period.
He said:
“Whether it’s good or bad, it will be unforgettable. My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars. I think if Peter wants a flying car, he should be able to buy one…I think it has a shot at being the most memorable product unveiling ever. [It will be unveiled] hopefully before the end of the year. You know, we need to make sure that it works. This is some crazy technology in this car. Let’s just put it this way: if you took all the James Bond cars and combined them, it’s crazier than that.”
Additionally, he said the vehicle would not be something that would prioritize safety. Musk said that “If safety is your number one goal, do not buy the Roadster.” It’s made for speed and excitement, not for grocery-getting.
Elon Musk just said some crazy stuff about the Tesla Roadster
As the April 1 unveiling event that was originally planned was nearing without any communication to fans, media, or anyone who would potentially be in attendance, it seemed to be pretty obvious that Tesla was not ready to pull the trigger on the event quite yet.
There could be some last-minute things to finalize, or it could be something else. One thing is for certain, though: we are not super surprised that things were moved back.
Tesla has definitely been putting some things in motion for the Roadster. A few months back, Tesla started to ramp up hiring for the Roadster, and earlier in March, it submitted a patent application for a new seat design.

Tesla named by U.S. Gov. in $4.3B battery deal for American-made cells
What began as an open secret in the energy industry was confirmed by the U.S. Department of the Interior on Monday: Tesla is the buyer behind LG Energy Solution’s blockbuster $4.3 billion battery supply agreement.
What began as an open secret in the energy industry is becoming more real after the U.S. Department of the Interior named Tesla as the stakeholder in the LG Energy Solution’s blockbuster $4.3 billion battery supply agreement.
Tesla and LG Energy Solution are expanding their partnership to build a LFP prismatic battery cell manufacturing facility in Lansing, Michigan, launching production in 2027. The announcement, made as part of the Indo-Pacific Energy Security Summit results, ends months of speculation.
“American-made cells will power Tesla’s Megapack 3 energy storage systems produced in Houston, creating a robust domestic battery supply chain.”, notes a press release on the U.S. Department of the Interior website.
Tesla has long utilized China’s Contemporary Amperex Technology Co. (CATL), the world’s largest LFP battery maker, as one of its primary suppliers. That relationship made financial sense for years, considering that Chinese LFP cells were cheap, abundant, and reliable. But with escalated tariffs on Chinese imports and an increasingly growing Tesla Energy business that’s particularly reliant on LFP cells for products including its Megapack battery storage units designed for utilities and large-scale commercial projects.
The announcement of a deepened partnership between LG Energy Solution and Tesla has strategic logic for both parties. For Tesla, it secures a tariff-compliant, domestically produced battery supply for its fast-growing energy division. LGES, now producing LFP batteries in Michigan, becomes the only major supplier currently scaling U.S. production, outpacing rivals like Samsung SDI and SK On. LG Energy Solution’s Lansing plant, formerly known as Ultium Cells 3, was previously operated as a joint venture with General Motors. LGES acquired GM’s stake in May 2025 and now fully owns the site, with a production capacity of 50 GWh per year. LG Energy said the contract includes options to extend the supply period by up to seven years and boost volumes based on further consultations.
For the broader industry, the ripple effects are significant. This deal signals that domestic battery manufacturing can be financially viable and not just aspirational. Utilities, energy developers, and rival automakers will take note as American-made LFP supply becomes a competitive reality rather than a distant promise.
For consumers, the benefits will take time but are real. A more resilient, U.S.-based supply chain means fewer price shocks from trade disputes, more stable Megapack availability for the grid storage projects that reduce electricity costs, and long-term downward pressure on energy storage prices as domestic production scales.
Deliveries are set to begin in 2027 and run through mid-2030, and as grid storage demand accelerates, reliable, US-made battery supply is no longer a future ambition. It is becoming a core requirement of the country’s energy strategy.
