SpaceX scraps first Starship prototype to make way for new and improved rockets
A bit less than a month after SpaceX’s first full-scale Starship prototype was partially destroyed during testing, the damaged rocket has been almost completely scrapped to make way for new and improved Starships.
On November 20th, SpaceX effectively tested the Starship Mk1 – the first full-scale prototype – to destruction, pressurizing the rocket’s tank section (lower half) until it quite literally popped its top. The pressure wave that failure created damaged almost every internal component of the massive vehicle, all but guaranteeing that SpaceX would have to scrap the vehicle and move on to new prototypes.
Those future prototypes will take advantage of the many, many lessons learned from Starhopper’s two test flights and several additional grounded tests, as well as the many learning experiences presented through Starship Mk1’s pathfinder manufacturing, assembly, and test campaign. As is SpaceX’s signature, the company is choosing to learn by building actual hardware and making the inevitable mistakes that come hand in hand with such an eccentric and ambitious program.
Above all else, SpaceX is trying to redefine the minimum infrastructure needed to build high-performance launch vehicles at a scale comparable to or even larger than NASA’s Saturn V, the largest rocket ever successfully launched. Modern rockets like Falcon 9 and Atlas V are built in relatively clean and environmentally-controlled environments and Saturn I and V – while quite a bit less sterile – were at least built inside large hangar-like facilities.
With Starship, SpaceX instead wants to build rockets even larger than Saturn V out in the elements and with a far more common (and thus affordable) workforce, (theoretically) made possible in large part thanks to its extensive use of stainless steel. Case in point, Starhopper – a low-fidelity Starship test bed – was quite literally welded together on the South Texas coast by welders far more familiar with building water towers. While not without its teething pains, Starhopper proved to be incredibly sturdy and resistant to anomalous behavior and successfully performed two separate flight tests in July and August 2019.
Three months after Starhopper’s second and final hop test, SpaceX’s Starship Mk1 tank section – the lower half of the rocket – was moved to the launch site and began a series of tanking tests. The first few tests were completed successfully and focused on searching for leaks with a neutral cryogenic liquid (likely liquid nitrogen). After the majority of those leaks were sealed, SpaceX moved into liquid oxygen load testing a few days later. For unconfirmed reasons, it turned out that that first liquid oxygen pressure test would also be Starship Mk1’s last.
On November 20th, SpaceX pressurized Starship Mk1 to its limits, with almost all of the visible creases and wrinkles in its steel surface visibly smoothing out as the supercool liquid oxygen caused frost to form on the exterior. Ultimately, SpaceX pushed the vehicle beyond its limits and its uppermost tank dome quite literally popped off of Starship’s tank section, whether the overpressure event was intentional or unexpected. The force of that overpressure event essentially sent a shockwave through Starship, crushing and warping its two remaining tank domes and transfer tubes like an aluminum soda can.
In simpler terms, very few parts of Starship Mk1 escaped unharmed, all but guaranteeing that it would not be worth the effort to repair it. Instead, SpaceX has almost entirely scrapped the prototype over a period of two weeks. According to an official statement released shortly after Mk1’s failure, SpaceX will attempt to recover and reuse as much of Mk1 as it can and those few salvageable parts will be added to an entirely new prototype, deemed Starship Mk3.
Although it’s disappointing that Starship Mk1 was unable to perform any kind of Raptor engine testing, let alone flight tests, it’s safe to say that the pathfinder prototype has been well worth the time and effort it took to build. Regardless of flight or engine testing, a ton of Mk1’s value lies in its utility as a hands-on, physical testbed for SpaceX employees to perform experiments and learn how to build steel rockets – and build them outside in less than friendly weather conditions.
SpaceX is in the midst of rapidly expanding its presence in Boca Chica, Texas, including a new launch control center, an expanded landing and launch pad, new production facilities, and more. The company has also just begun churning out numerous monolithic (single-weld) steel rings that will likely become part of Starship Mk3 in the near future. It will likely be several months before that next-generation prototype is as close to completion as Starship Mk1 was, but it should be well worth the wait and well worth its predecessor’s sacrifice.

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.
