SpaceX nails second Falcon 9 landing in 48 hours, fairing catch foiled by weather
Just a handful of days after SpaceX’s second-ever successful launch and landing of their upgraded Falcon 9 Block 5, the company has completed the same feat on the opposite side of the United States, debuting the Block 5 rocket with a launch and booster recovery from California’s Vandenberg Air Force Base (VAFB).
The booster in question, Falcon 9 B1048, is the third Block 5 booster to roll off of SpaceX’s Hawthorne, CA assembly line and is now the first Block 5 rocket to launch from the company’s California launch facilities. On the opposite coast, SpaceX’s second Block 5 Falcon 9 booster (B1047) completed its own successful launch and landing, lofting the heaviest commercial satellite to ever reach orbit (Telstar 19V).
While weather during camera setup was absolutely spectacular, the predawn launch window meant that no sun was available to force the ever-present VAFB fog back over the ocean. (Pauline Acalin)
Seven months, fourteen launches
Today’s near-flawless predawn mission saw Falcon 9 place 10 Iridium NEXT satellites in a polar Earth orbit, during which the rocket’s Block 5 booster completed the first landing on Just Read The Instructions in nearly ten months and Mr Steven made his first attempt at catching a parasailing Falcon fairing with his massive net and arms upgrades. Those upgrades, tracked tirelessly by Teslarati photographer Pauline Acalin for the better part of July, took barely a month to go from a clean slate (old arms and net fully uninstalled) to operational, fairing-catching status, an ode to the incredible pace at which SpaceX moves.
Sadly, the vessel’s Iridium-7 fairing catch attempt was sullied from the start by inclement weather – primarily wind shear – that significantly hampered the accuracy of each fairing halve’s parafoil guidance, meaning that Mr Steven’s crew did see the parasailing halves touch down, but too far away to catch them in Mr Steven’s large net. Falcon 9 B1048 had its own difficulties thanks to what engineer and webcast host John Insprucker described as “the worst weather [SpaceX] has ever had” for a Falcon booster landing. Nevertheless, Falcon 9 appeared to stick an off-center but plenty accurate landing aboard drone ship JRTI, although SpaceX technicians are likely going to wish they had the same robotic stage securer located aboard OCISLY on the opposite coast.

Just Read The Instructions, on the other hand, was similarly tracked but primarily to verify that nothing was happening – the vessel’s last operational trip to the Pacific Ocean dates back to the first half of October 2017. Since then, SpaceX began a process of intentionally expending Falcon 9 boosters that had already flown once before, choosing to essentially start from scratch with a fresh fleet of highly reliable and reusable Falcon 9 Block 5 boosters rather than recover older versions of the rocket and attempt to refurbish them beyond the scope of their designed lifespans.
The Block 5 design, however, has taken the countless lessons-learned from flying and reflying previous versions of Falcon 9 and rolled them all into one (relatively) final iteration of the ever-changing rocket. With any luck and at least a little more iteration, Falcon 9 Block 5 boosters should be capable of launching anywhere from 10 to 100 times, 10 times with minimal or no refurbishment and 100 times with more regular maintenance, much like high-performance jet aircraft do today.
Looks good, but so many details need to be right. Journey back from hypersonic becomes extremely difficult as velocity increases. Altitude is easy, velocity is hard.

With three successful launches of new Block 5 boosters now under the new version’s belt, it’s safe to say that the rocket is off to an extremely good start. The most important milestones to watch for over the next several weeks and months will be the first reflight of a recovered Block 5 rocket, the first reuse of a Falcon 9 payload fairing, and then the first third/fourth/fifth/etc. reuse of Block 5 booster. On the horizon, of course, is SpaceX CEO Elon Musk’s challenge to launch a Falcon 9 Block 5 booster two times in less than 24 hours, and do so before the end of 2019.

Roughly 3,000 miles to the East, SpaceX’s just-recovered Florida Block 5 booster wrapped up a picture-perfect arrival in Port Canaveral aboard drone ship Of Course I Still Love You at the exact same time as another Block 5 rocket was launching (and landing) on the opposite coast.

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.

Tesla expands Unsupervised Robotaxi service to two new cities
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.
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.

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.
