SpaceX Falcon 9 rocket nails first operational NASA astronaut launch [updated]
Update: SpaceX has successfully resolved a handful of minor thermal control issues facing the brand new Crew Dragon capsule currently ferrying four astronauts in low Earth orbit (LEO).
As previously noted, shortly after the spacecraft reached orbit, two redundant thermal control system pumps registered pressure spikes, pushing Crew Dragon to use the backup pump. SpaceX was able to resolve that issue, effectively restarting the pumps and confirming healthy operation. Several hours later, the backup pump (“Loop B”) suffered another minor issue but was again returned to healthy operations. Simultaneously, Crew-1 astronauts found themselves stuck at an (admittedly comfortable) cabin temperature of 23C (~73F).
More pressingly, three of four heaters used to warm the propellant fed to Crew Dragon’s small Draco maneuvering and attitude control thrusters were automatically disabled a few hours after liftoff. Essential for most operations in orbit and necessary for Dragon to be allowed to remain docked with the ISS, restoring the functionality of at least one of the three heaters was essential, and SpaceX was thankfully able to restore function to all three by relaxing excessively conservative limits in the spacecraft’s flight software. Thanks to SpaceX’s fast work, Dragon is now in perfect health and ready for two crucial Draco burns at 11:20 am and 12 pm EST (UTC-5) on Monday, November 16th and is still scheduled to arrive at the ISS around 11 pm EST.
Right on schedule, a SpaceX Falcon 9 rocket has successfully lifted off on the company’s operational NASA astronaut launch debut, sending four crew members on their way to the International Space Station (ISS) in a historic moment for commercial spaceflight.
Days prior, NASA and SpaceX completed a multi-day “flight readiness review (FRR),” the results of which made SpaceX the first private company in human history to be qualified by a national space agency for routine astronaut launches. As is now more or less routine, the SpaceX Falcon 9 rocket assigned to NASA’s Crew-1 mission performed flawlessly over the 12 minutes it was involved in the launch, including nominal booster and upper stage performance, a successful booster landing at sea, and a smooth Dragon deployment from Falcon 9’s expendable second stage.
In a small point of concern, Crew Dragon capsule C207 (colloquially named Dragon Resilience by its crew) appeared to suffer a minor hardware or software fault shortly after orbital insertion, offering the first public glimpse behind the scenes as ground teams coordinated with Dragon’s orbiting astronaut crew to diagnose and fix the issue.
According to information revealed by SpaceX and NASA officials as they interacted with Crew-1 NASA astronauts Mike Hopkins, Victor Glover, Shannon Walker, and Japanese (JAXA) astronaut Soichi Noguchi, Crew Dragon’s fault detection software was tripped sometime after reaching orbit. Both thermal control system (TCS) “loop” pumps – likely referring to pumps used to circulate a liquid-based radiator system to maintain capsule temperature – experienced off-nominal pressure spikes, causing the spacecraft computer to switch to the second pump (“Loop B”).
As SpaceX’s main earth-to-ground communications team member (CapCom) noted, the TCS pump issue was far from critical given that both pumps appeared to be healthy – and one of those two redundant pumps functioning healthily – moments after Dragon alerted its passengers to the issue. Deemed to be not a showstopper, SpaceX continued the mission and permitted Crew Dragon to begin its first orbit-raising thruster burn – the first of a fairly complex series of ‘phasing’ burns needed to safely rendezvous with the International Space Station (ISS).
Unfortunately, due to a 24-hour weather delay from November 14th to November 15th, the complexities of orbital rendezvous mean that Crew Dragon’s Crew-1 mission to the ISS will involve a roughly day-long cruise phase. Had SpaceX been able to launch on the 14th, the cruise phase would have been just 8.5 hours long – perhaps the fastest crewed US space station rendezvous ever. Crew-1 will thus align quite closely with SpaceX’s Demo-2 astronaut launch debut, although likely not interspersed with manual astronaut piloting tests this time around.
On top of Crew Dragon’s thus far successful performance, Falcon 9 also completed a task critical for future Crew Dragon launches when new booster B1061 safely landed aboard SpaceX drone ship Of Course I Still Love You (OCISLY). While normally a distinctly secondary objective, booster recovery was all but essential for SpaceX and NASA during the Crew-1 launch after NASA’s recent reveal that B1061 has been assigned to launch Crew-2 as early as March 31st, 2021. In the likely event that the Falcon 9 booster is in good condition and NASA signs off after shadowing SpaceX’s refurbishment process, SpaceX will also become the first private company in history to launch astronauts into orbit on a flight-proven rocket booster. Additionally, thanks to plans to reuse Crew Dragon capsule C206 of Demo-2 fame, Crew-2 will also mark the first time in history that US astronauts launch into orbit in a reused space capsule.
If the Crew-1 cruise phases goes according to plan, Crew Dragon will autonomously ferry Hopkins, Glover, Walker, and Noguchi from a ~200 km (~125 mi) parking orbit to the International Space Station (ISS) between now and Monday, November 16th, nominally docking with the space station around 11 pm EST (04:00 UTC 17 Nov). From liftoff to reentry, Crew-1 is expected to be the longest continuous spaceflight of a US spacecraft in American history, spending approximately six months in orbit. For JAXA astronaut Soichi Noguchi, his Crew-1 launch also made him the third astronaut in human history to fly to orbit on three separate vehicles.
Ultimately, for SpaceX, the company has never been closer to achieving its foundational goal of enabling the affordable expansion of humanity into space than it is after today’s successful Crew-1 launch.
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.
