SpaceX nails first Starship landing weeks after NASA Moon lander contract [updated]

Update: For the first time ever, SpaceX has successfully landed a Starship prototype in one piece and kept the giant steel rocket intact throughout the post-flight safing process. The fun, however, is just beginning.

First and foremost, excluding simpler Starship prototypes SN5 and SN6, Starship SN15 is the first prototype to actually complete that safing process. In theory, safing a liquid fuel rocket is a fairly novel task given so few rockets are actually reusable. It involves detanking, purging plumbing and Raptor engines, deactivating explosive flight termination system (FTS) charges, and more generally verifying the health and status of all systems. With a rocket as complex as Starship, SpaceX is treading new ground with almost every step, meaning that even something as seemingly benign as keeping a rocket intact after a successful landing carries risk (e.g. SN10).

SN5 and SN6 also had a rough go of things even after surviving their landings and it took anywhere from 12 to 24+ hours before SpaceX declared either vehicle safe to approach. The degree to which Starship SN15’s launch and landing was a success is hinted at by the fact that SpaceX had teams approaching the rocket less than four hours after touchdown. Still, more than six hours after landing, those SpaceX teams were still working to transport a crane to the site after rolling a self-propelled modular transporter (SPMT) within the vicinity of Starship SN15.

Eventually, that crane will lift SN15 onto a custom jig installed on said SPMT and take its flimsy, unreliable legs out of the equation. At that point, the Starship prototype will well and truly be safe and secure and ready for whatever else SpaceX may have in store, be that a quiet future as a permanent display or the program’s first reuse. Stay tuned for updates as SpaceX secures the historic rocket and prepares to reopen the highway to the public.

In perhaps the best possible news that could have followed NASA’s historic SpaceX Moon lander contract, the company has successfully landed a Starship prototype in one piece – without it exploding – for the first time ever.

In spite of unusually unreliable live views from the rocket’s onboard cameras, possible due to SpaceX using Starlink as a Starship antenna for the first time, Starship serial number 15 (SN15) touched down at the very edge of the landing pad a bit less than seven minutes after lifting off from SpaceX’s Boca Chica launch facilities.

Like all four of its predecessors, Starship SN15 ignited all three of its Raptor engines and gradually ascended to an altitude of ~10 km (6.2 mi), shutting down one engine every 90 or so seconds along the way. At apogee, after briefly hovering under the power of one engine, the last Raptor cut off and Starship angled over onto its belly and simply fell back to Earth.

Using four large steel ‘flaps,’ the rocket controlled its descent like a skydiver down to approximately 500m (~2000 ft) above the ground and ignited two or three of its Raptors to aggressively flip into a tail-down orientation. SN15 then slowed all the way down under the thrust of two of those engines for an exceptionally soft – albeit inaccurate – landing on a concrete pad.

Much like SN10, which caught on fire shortly before touchdown, landed intact, and then exploded after that fire continued to burn, Starship SN15 appeared to catch fire shortly after landing and a significant fire burned for at least five minutes before disappearing. As a result, be it intentional on behalf of SpaceX or simple luck, SN15 did not explode after touchdown. The Starship also landed far more gently than Starship SN10, which effectively pancaked its tiny legs and embedded its skirt directly into concrete.

Ultimately, Starship SN15’s fully successful launch and landing is an immense achievement after four failed – but data-rich – attempts and confirms that SpaceX is on the right track. Perhaps even more importantly, the success is quite possibly the best conceivable vindication for NASA after the space agency made the shocking decision to return humanity to the Moon with SpaceX’s Starship.

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.”

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.

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.

Tesla has taken a major step forward in its autonomous ride-hailing ambitions.

On April 18, the company’s official Robotaxi account announced that Robotaxi service is now rolling out in Dallas and Houston, Texas. The update signals the rapid scaling of unsupervised autonomous operations in the Lone Star State.

The announcement includes a compelling 14-second video captured from inside a Model Y. Shot from the passenger perspective, the footage shows the vehicle navigating suburban roads in both cities with zero driver intervention, with no Safety Monitor to be seen.

Tesla also shared geofence maps highlighting the initial service areas: a compact zone in Houston covering parts of Willowbrook and Jersey Village, and a similarly defined area in Dallas near Highland Park and central neighborhoods.

This expansion builds directly on Tesla’s existing operations. Robotaxi has been ramping unsupervised rides in Austin for months and maintains activity in the San Francisco Bay Area.

With Dallas and Houston now live, Texas hosts three active hubs—an impressive concentration that triples the company’s Lone Star footprint in just weeks. The move aligns with Tesla’s Q4 2025 earnings guidance, which outlined a broader H1 2026 rollout across seven U.S. cities, including Phoenix, Miami, Orlando, Tampa, and Las Vegas.

Texas offers favorable regulations, high ride-share demand, and relatively straightforward suburban-to-urban driving patterns ideal for early autonomous scaling. While initial geofences appear modest—roughly 25 square miles per city—Tesla has historically expanded these zones quickly as it gathers real-world data.

Tesla confirms Robotaxi expansion plans with new cities and aggressive timeline

Unsupervised operation marks a critical milestone: passengers can summon, ride, and exit without safety drivers, a leap beyond many competitors still requiring human oversight.

For Tesla, the implications are significant. Successful scaling in major metros could accelerate the transition to a fully driverless fleet, unlocking new revenue streams and validating years of Full Self-Driving investment.

Riders gain convenient, potentially lower-cost mobility, while the company edges closer to Elon Musk’s vision of Robotaxis transforming urban transport.

As Tesla pushes into more cities this year, today’s launch in Dallas and Houston underscores its momentum. Hopefully, Tesla will be able to expand unsupervised rides to another U.S. state soon, which will mark yet another chapter in this short-but-encouraging Robotaxi story.
