SpaceX begins Starship launch mount installation at historic Pad 39A in Florida
At the same time as SpaceX’s Boca Chica, Texas team is working around the clock to prepare Starship Mk1 for several major tests, the company is building a second dedicated Starship launch complex at Pad 39A and as of November 4th, that construction effort has reached a symbolic milestone.
According to photos taken by local resident and famed rocket and ship photographer Julia Bergeron on a bus tour of Kennedy Space Center (KSC), SpaceX has officially begun to install a large steel structure at Launch Complex 39A, a pad the company has leased from NASA since 2014. Known as a launch mount, the massive structure will one day support SpaceX’s first East Coast Starship and Super Heavy static fires and test flights.
At SpaceX’s Boca Chica, Texas Starship facilities, the company has already made a huge amount of progress fabricating and outfitting a brand new launch mount that will soon support Starship Mk1’s first propellant loading, static fire, and flight tests. The spartan steel structure looks different from anything SpaceX has built in the past for Falcon 9 and is equally unrecognizable alongside the renders of a finished-product launch pad included in an updated Starship launch video.
What is undeniable, nevertheless, is the speed with which technicians have taken the Texas launch mount from a group of unconnected, partially-finished parts to a nearly complete structure with the business half of Starship Mk1 installed on top. SpaceX workers have built the mount, completed a large amount of plumbing to connect it to nearby liquid oxygen, methane, nitrogen, and helium reserves, and installed Starship on the mount in less than two months. The final integration of different prefabricated pieces began barely a month before Starship was moved to the pad, as pictured below.
Two pads, two approaches
Although Boca Chica’s launch mount is quite large, based on Julia’s photos of Pad 39A, Florida’s nascent launch mount is going to be significantly bigger. The section that SpaceX began installing in the first days of November appears already be much taller than the mount in Texas, and it also looks more like a rectangular corner than anything resembling part of Boca Chica’s hexagonal structure.
At the same time, the apparent rectangular corner being worked on in Florida would be a much better fit for the partially-enclosed launch mount structure shown in SpaceX’s official 2019 Starship launch video.
This is all to say that it looks like SpaceX is taking significantly different approaches with its two prospective Starship launch sites, which should come as no surprise in the context of the Starship program. SpaceX is already competitively building multiple Starship prototypes at two separate facilities in Boca Chica, Texas and Cocoa, Florida, a competition that has already produced visible differences between Mk1 and Mk2 prototypes. There’s a good chance that SpaceX intends to preserve that competitive atmosphere with Starship’s launch facilities, not just the rocket itself.
Additionally, it’s clear that Texas and Florida currently serve very different roles in the actual testing of Starship prototypes. Boca Chica has been active in that regard for more than half a year, ranging from the first Starhopper static fire in April to Starhopper’s 150-meter test flight in August. Florida has been almost entirely focused on iterating the build process itself and has already prefabricated nearly two dozen single-weld steel rings that will soon become Starship Mk4.
A step further, SpaceX CEO Elon Musk has made it clear that he is pushing for Starship’s first orbital launch to occur in the first half of 2020, an incredibly ambitious target given that the first Super Heavy booster prototype has yet to begin fabrication or assembly of any kind. Regardless, with that ambitious target in mind, SpaceX still needs to try to build a launch facility capable of standing up to a vehicle more powerful than Saturn V unfathomably quickly.
Head in the clouds
More likely than not, SpaceX’s Pad 39A Starship facilities will (attempt to) be that launch facility. An August 2019 environmental impact statement revealed that SpaceX would avoid Pad 39A’s massive flame trench and instead build a separate water-cooled thrust diverter, a technology SpaceX is extremely familiar with.
The diverter will likely have to be larger than anything SpaceX has ever attempted to build and will take a significant amount of time and money to fabricate, but the approach could potentially allow SpaceX to build Super Heavy-rated launch facilities from scratch in just 6-12 months. Put simply, however, SpaceX is not going to want to build a Starship-sized thrust diverter and launch mount in Florida if it will almost immediately have to build a second, larger replacement big enough for orbital launch attempts with Super Heavy.
All things considered, it’s thus reasonably likely that SpaceX’s first draft of Florida Starship launch facilities will immediately jump to something sized for Super Heavy static fires and launches, even if that means it will take much longer to complete. If the pace of launch pad development in Boca Chica is anything to go by, it’s entirely possible that SpaceX will go from breaking ground at Pad 39A (mid-September 2019) to a more or less complete Starship-Super Heavy launch mount in roughly half a year.
Even if it takes more than a year to build, SpaceX could still be ready to attempt Starship’s first orbital launch well before the end of 2020.

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.
