Four days after they headed out into the Atlantic Ocean, twin SpaceX fairing recovery ships Ms. Tree and Ms. Chief have returned to port with both halves of a Falcon 9 fairing, although they appear to have picked up some battle scars along the way.

Ms. Tree and its near-identical sibling Ms. Chief departed Port Canaveral on December 14th and arrived on station – 790 km (490 mi) off the coast of Florida – some 36 hours later. Each outfitted with a quartet of arms and pair of nets, it was the first time both ships successfully made it out into the Atlantic for a simultaneous fairing catch attempt, having been foiled by high seas during a prior November outing.

For unknown reasons, after the duo’s November false start, both ships stopped for almost two weeks at a South Carolina port, perhaps indicating that SpaceX was concerned about the structural integrity of the ships’ seemingly fragile net mechanism. In February 2019, Mr. Steven (now Ms. Tree) lost two of its four arms while heading downrange for an attempted catch, apparently broken off by pitching caused by high seas. Further strengthening the case that their net mechanisms are rather fragile, both Ms. Tree and Ms. Chief again suffered damage after their Kacific-1/JCSAT-18 Falcon 9 fairing recovery attempt.

Both ships arrived back at Port Canaveral on December 18th and were caught by Teslarati photographer Richard Angle while passing through the narrow mouth of the port. GO Ms. Chief took the lead, revealing a Falcon 9 fairing half snugly secured with a tarp on her deck – the ship’s very first launch vehicle hardware recovery.

First (partially) successful fairing recovery quite literally under wraps, Ms. Chief nevertheless did not make it through the rite of passage unscathed. Oddly, it appears that just one of the ship’s eight white arm supports is missing (the rear right or aft starboard arm), visibly resulting in the arm slouching a bit compared to its siblings. Intriguingly, it appears that the arm is partially stretching – and thus potentially resting on – Ms. Chief’s net and rigging.

The fact that only one of the arm’s two beams (of eight total) seems to have failed is more immediately indicative of possible human error during installation or a defective attachment mechanism, although it’s entirely possible that a fluke of weather could have damaged just the one beam.

Thankfully, Ms. Tree (formerly Mr. Steven) appears to have made it through the recovery mission with all four arms fully intact, although the ship clearly struggled with a separate mechanism. Notably, Ms. Tree seems to have struggled to use its secondary net to lift its fairing half out of the sea and onto her deck, with that smaller net clearly suffering a multitude of rips and tears at some point during the process. Her recovered fairing half is somewhat awkwardly strewn on the deck with no obvious attempt to rectify the issue, indicating that the net may have torn mid-lift, causing the fairing to fall maybe 5-10 feet.

If it did actually fall onto Ms. Tree’s deck, that will almost certainly be visible in the form of damage to its aluminum-composite honeycomb structure and white insulation coating.

Ultimately, fairing recovery continues to prove itself to be a major challenge, although SpaceX obviously has no intention of giving up. With two successful catches already in hand, it’s clear that fairing recovery is undeniably possible and is more a matter of tweaking existing systems than starting from scratch. Much like Falcon 9 booster recovery had and its fair share of failed landings even after the first success, it will likely take quite a while for SpaceX to optimize fairing recovery to the point that it can be considered reliable.

For now, routine fairing recovery and reuse will likely continue to be Falcon 9’s white whale, at worst adding to the excitement of every SpaceX satellite launch.

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.
