SpaceX preparing giant crane to assemble Starship’s first Florida launch tower
SpaceX has begun staging and assembling parts of a giant crane it will soon need to stack Starship’s first East Coast launch tower and install other major launch pad components.
The presence of the base of that crane at SpaceX’s NASA Kennedy Space Center (KSC) Launch Complex 39A was visually confirmed by NASASpaceflight.com photographers during a weekly aerial tour of the area on June 3rd. Four days later, Teslarati photographer Richard Angle observed more major crane components on their way to Pad 39A, including the crane’s cabin.
More likely than not, the crane SpaceX or its contractor has begun assembling at 39A is a Liebherr LR 11350, the same kind of crane the company used to assemble Starship’s first orbital launch site and tower in South Texas. In fact, given how few LR 11350s there are in existence, it’s entirely possible that it’s the exact same crane. Assembly of that crane began around April 2021 and took a month and a half, at which point it was finally ready to lift an extended boom long enough to assemble a tower almost 500 feet (~150 meters) tall.
Pad 39A’s Starship launch tower is expected to be very similar to Starbase’s, although it will undoubtedly carry over numerous design changes thanks to lessons learned while building and outfitting the first tower. In fact, SpaceX has already assembled five of the nine individual sections that will eventually be stacked to form that tower, and one such change is already obvious. Instead of stacking each tower section as soon as its barebones framework is complete, SpaceX is taking a more methodical approach to its second launch tower. In an apparent attempt to limit the amount of work that needs to be done at Pad 39A itself, each of those segments is being thoroughly outfitted with secondary structures (ladders, doors, walkways, frames, raceways, etc.) before stacking.
SpaceX may even pre-install most of the thousands of feet of plumbing needed to connect a Starship to ground systems located around 90 meters (~300 ft) below it. Once stacked, each section – including all those partial propellant and gas lines – will still need to be joined together, but that process should be far easier than fully installing all the systems the tower needs to do its job. Outfitting Starbase’s launch tower, for example, took SpaceX around half a year and, to some extent, is still ongoing 11 months after the final stack. That likely explains why Starship’s 39A tower section assembly appears to be taking more time. With any luck, partially combining the outfitting and section assembly stages will significantly expedite final assembly, as far less work will need to be done at extreme heights or require a skyscraper-sized crane.
Through Starbase, SpaceX has already demonstrated the ability to stack a Starship launch tower from its unoccupied concrete base to its final height of ~145 meters (~475 ft) in about two months flat. While SpaceX will have to slalom its way around Pad 39A’s busy launch manifest, there’s no reason to believe that Starship’s first Florida launch tower won’t be stacked at least as quickly.
Aside from the arrival of crane parts, SpaceX has also made great progress on the Starship launch site itself. In the last few weeks, the company appears to have completed several significant concrete pours on the tower base. SpaceX has also installed all six of the pedestal-like orbital launch mount’s legs after months of foundation work. Elsewhere at Cape Canaveral, a different team has made excellent progress assembling the massive donut-like platform that will sit on top of those legs. Due to its extreme weight (possibly around 300 metric tons, per Elon Musk’s comments on the Starbase mount), the same LR 11350 crane will also be needed for that major installation milestone.
Plenty of parts are still missing, of course. Four tower sections still need to be assembled. Starship’s first Florida launch tower will need its own set of two ‘chopstick’ arms for lifting and (maybe) catching Starship and Super Heavy, as well as a third swinging quick-disconnect arm to connect Starship to ground systems. Aside from delivering several new tanks, SpaceX has also made no apparent progress on adding a massive methane propellant farm to Pad 39A, and it’s possible that the pad’s oxygen farm will also need to be expanded. Propellant storage has proven to be a major headache for SpaceX at Starbase.
Nonetheless, SpaceX is making great progress on most of the most difficult parts of Starship’s first Florida launch site, and there’s a good chance that just like its launch mount, work on the pad’s tower arms is already underway somewhere offsite. A great deal of work remains to be done but SpaceX is still well on its way to launching Starships out of Kennedy Space Center in the not-too-distant future.
Tesla (NASDAQ: TSLA) is set to hold its Earnings Call for the first quarter of 2026 on Wednesday, and there are a lot of interesting things that are swirling around in terms of speculation from investors.
With the company’s executives, including CEO Elon Musk, answering a handful of questions that investors submit through the Say platform, fans want to know a lot of things about a lot of things.
These five questions come from Retail Investors, who are normal, everyday shareholders:
- When will we have the Optimus v3 reveal? When will Optimus production start, since we ended the Model S and Model X production earlier than mid-year? What’s the expected Optimus production rate exiting this year? What are the initial targeted skills?
- What milestones are you targeting for unsupervised FSD and Robotaxi expansion beyond Austin this year, and how will that drive recurring revenue?
- How will Hardware 3 cars reach Unsupervised Full Self-Driving?
- When do you expect Unsupervised Full Self-Driving to reach customer cars?
- When will Robotaxi expand past its current limited rollout?
Additionally, these are currently the three questions that are slated to be answered by Institutional Firms, which also answer a handful of questions during the call:
- Now that FSD has been approved in the Netherlands and is expected to launch across Europe this summer, can you discuss your Robotaxi strategy for the region?
- What enabled you to finish the AI5 tapeout early and were there any changes to the original vision? Last week, Elon said AI5 will go into Optimus and the Supercomputer, but one month ago said it would go into the Robotaxi. Has AI5 been dropped from the vehicle roadmap?
- Given the recent NHTSA incident filings, can you update us on the Robotaxi safety data? If safety validation remains the primary bottleneck, why not deploy thousands of vehicles to accelerate the removal of the safety driver?
The questions range through every current Tesla project, including FSD expansion and Optimus. However, many of the answers we will get will likely be repetitive answers we’ve heard in the past.
This is especially pertinent when the questions about when Unsupervised FSD will reach customer cars: we know Musk will say that it will happen this year. Is Tesla capable of that? Maybe. But a more transparent answer that is more revealing of a true timeline would be appreciated.
Hardware 3 owners are anxiously awaiting the arrival of FSD v14 Lite, which was promised to them last year for a release sometime this year.
The Earnings Call is set to take place on Wednesday at market close.

Elon Musk reveals shocking Tesla Optimus patent detail
What looked promising on paper and in simulations failed to deliver the reliability required for a robot expected to handle delicate tasks like folding laundry, assembling electronics, or assisting in factories and homes.
Elon Musk revealed a shocking detail on the Tesla Optimus patent that was revealed last week. Despite it being made public for the first time, Musk said the company has already moved on from the design, an incredible truth about the development of new technology: things move fast.
Musk dropped a bombshell about the Tesla Optimus humanoid robot hand patent that was released last week. Musk, candidly replying to a post late at night on X, revealed that what is a new technology to many fans and insiders is actually old news to those developing the tech directly.
“We already changed the design,” Musk said. “This one didn’t actually work.”
We already changed the design. This one didn’t actually work.

Patents, after all, are often viewed as blueprints for future products. Yet Musk revealed that the rolling contact mechanism—intended to provide smooth, low-friction articulation in the fingers—had already been scrapped after real-world testing exposed its shortcomings.
What looked promising on paper and in simulations failed to deliver the reliability required for a robot expected to handle delicate tasks like folding laundry, assembling electronics, or assisting in factories and homes.
The hand has been one of the biggest challenges for Tesla engineers since Optimus development started years ago. Musk has said that there is not enough recognition for how incredible and useful the human hand is, and designing one for a humanoid robot has been the biggest challenge of all.
Tesla is stumped on how to engineer this Optimus part, but they’re close
This moment underscores the persistent engineering hurdles in achieving reliable humanoid hand dexterity. Human fingers are marvels of evolution: 27 bones, intricate tendons, ligaments, and a network of sensors working in perfect harmony. Replicating that in metal and silicon is extraordinarily difficult.
Rolling contacts promised reduced wear and precise motion, but testing likely revealed issues with durability under repeated stress, grip stability on varied surfaces, or the micro-precision needed for fine motor skills.
These aren’t minor tweaks, but instead they represent fundamental challenges that have plagued robotics teams for decades. Even advanced competitors struggle here—hands remain the Achilles’ heel of most humanoids because the margin for error is razor-thin.
A fraction of a millimeter off, and a robot drops a glass or fails to button a shirt.
What makes Musk’s reply remarkable is how it signals Tesla’s direct communication style on prototype limitations. While many companies guard failures behind glossy marketing and vague timelines, Tesla openly shares setbacks.
Musk was forthcoming about the failure of this recent design. This transparency builds trust with investors, engineers, and fans. It shows Tesla treats Optimus development like true science: rapid iteration, rigorous testing, and zero tolerance for hype that doesn’t match reality.
The disclosure from Musk also highlights Tesla’s blistering pace of development. By the time the patents are published, which is often over a year after the initial filing, the technology has already evolved.
Optimus is far from a static product, and it’s a living project advancing weekly.
In the high-stakes race for general-purpose robots, Tesla’s approach stands out. Admitting a finger-joint design “didn’t actually work” isn’t a weakness—it’s confidence.
True innovation demands confronting failure head-on, and Musk just reminded the world that Optimus is being engineered that way. The next version of those hands is already in testing, and it will be better because Tesla isn’t afraid to say what didn’t work.

Tesla is sending its humanoid Optimus robot to the Boston Marathon
Tesla’s Optimus robot is heading to the Boston Marathon finish line
Tesla’s Optimus humanoid robot will be stationed at the Tesla showroom at 888 Boylston Street in Boston, right along the final stretch of the Boston Marathon today, ready to cheer on runners and pose for photos with spectators.
According to a Tesla email shared by content creator Sawyer Merritt on X, Optimus will be at the Boston Boylston Street showroom on April 20, coinciding with Marathon Monday weekend. The Boston Marathon finishes on Boylston Street, and the surrounding area draws hundreds of thousands of spectators along with international broadcast coverage. Placing Optimus there puts it in front of a massive public audience at zero advertising cost.
Just got this email. @Tesla’s Optimus robot is coming to Boston.

The Tesla showroom is at 888 Boylston Street, between Gloucester Street and Fairfield Street. The final mile of the marathon runs directly along Boylston Street, with runners passing the big stores before reaching the finish line at Copley Square.
Optimus was first announced at Tesla’s AI Day event on August 19, 2021, when Elon Musk presented a vision for a general-purpose robot designed to take on dangerous, repetitive, and unwanted tasks. In March 2026, Optimus appeared at the Appliance and Electronics World Expo in Shanghai, where on-site staff stated that mass production of the robot could begin by the end of 2026. Before that, it showed up at the Tesla Hollywood Diner opening in July 2025 and at a Miami showroom event in December 2025.
Tesla’s well-calculated display of Optimus gives the public a low-pressure first encounter with a robot that Tesla is preparing to soon deploy at scale. The company has previously indicated plans to manufacture Optimus robots at its Fremont facility at up to 1 million units annually, with an Optimus production line at Gigafactory Texas targeting 10 million units per year.

Musk has said that Optimus “has the potential to be more significant than the vehicle business over time,” and separately that roughly 80 percent of Tesla’s future value will come from the robot program. Whether that holds depends on production execution. For now, Boston gets a preview of what that future looks like, standing at the finish line on Boylston Street while 32,000 runners pass by.
