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.

Tesla shows what Roadster drivers will see on screen before thruster activation
Tesla’s Roadster video reveals a fighter jet inspired cockpit with a 5,500 PSI thruster gauge.
Tesla has given future owners their clearest look yet at the cockpit of its next generation Roadster. In a 34 second video posted to X on Friday afternoon, the company walked through the car’s touchscreen with a caption: “Inspired by fighter jet cockpits, Roadster’s interface was designed around the pilot.”
The clip opens on a black screen with red graphics and a 3D wireframe of the car, which sits beside the Roadster’s squared off yoke. Tapping parts of the model brings up controls for the rear wing, including low drag and high downforce positions, along with a charging page with a charge limit bar and a small music player. A row of tabs along the bottom reads Home, Vehicle, Listen, Climate and Navigate.
Most of the video is spent in Track Mode. The dashboard shows a live circuit map, a list of session lap times, brake and motor temperatures, and pressure and temperature readouts for each tire. A setup page lets the driver pick Auto, Low Drag, High Downforce or Custom aero modes, adjust aero balance and brake balance, and switch stability and traction control off. Along the bottom, a status bar reads “Thruster · 5,500 PSI” next to a “Boost Ready” indicator.
That gauge ties the software to the hardware Tesla showed off near Waco, Texas on October 15. The Thrust and Rocket versions use cold gas thrusters fed by carbon overwrapped pressure vessels, and Tesla lists 0 to 60 mph times of under 0.9 seconds and under 0.59 seconds for them, as Teslarati detailed in its breakdown of the three Roadster configurations. The base Performance car relies on a fan and ground sealing system for grip, and the aero settings on screen match the active wings and suction setup covered in our look at how the Roadster generates downforce.
The Roadster layout is a departure from the rest of Tesla’s lineup. Instead of a map centered screen, the Roadster puts the car itself at the center of the home page, and Tesla’s Roadster page lists two smaller forward displays alongside the main touchscreen. Tesla has not said whether any of the Track Mode telemetry will make its way to the Model 3 Performance or other vehicles.
The interface could still change before deliveries. Elon Musk said at the event that Roadster production will begin in 2028, and Tesla says the flagship Rocket version is not approved for public road use. Reservations are open with a $50,000 payment, while Thrust is listed as a limited release and Rocket is invite only.
Those who want to see the car in person will get their first chance this weekend. The Roadster goes on display in the lobby of the Petersen Automotive Museum in Los Angeles from October 24 to 27, according to Sawyer Merritt, the first time the public will be able to view it up close.

Tesla reveals Optimus Academy, where robots teach themselves
Tesla has begun building production quality Optimus robots in Fremont and revealed its training plan.
Tesla has started building Optimus on the high volume line it set up inside its Fremont factory, and the company says the robots coming off it are the first that meet the bar for a real product. “The bots coming off this line are the first production-quality bots that we have manufactured,” Tesla wrote in its third quarter shareholder letter, adding that it has “proven that the current manufacturing process for Optimus is suitable for a commercial product.”
The line sits in space that built the Model S and Model X until this spring. Tesla cleared the old vehicle line in 46 days, as Teslarati reported in July, to make room for robot production sized for one million units a year. On Wednesday’s earnings call, Elon Musk said most of the equipment for that capacity is already in Fremont, with output set to climb toward roughly 20,000 robots a week as the line ramps.
Musk described the ramp as a classic S curve. “The growth of Optimus is an S curve, but the initial curve is a shallow slope,” he said. The team is now refining the robot’s AI, electromechanical design, reliability and service life, and Musk expects that work to be finished by the end of next year, when Tesla plans to start delivering Optimus to outside companies for dangerous, repetitive and around the clock jobs.
The most interesting part of the call was how Tesla plans to teach the robots. Its cars send real driving data back to the AI team from millions of vehicles, but Optimus has no fleet like that yet. “A big difference with Optimus versus the cars is we don’t have this vast fleet of cars from which we can gather training data,” Musk said. Tesla’s answer is an Optimus Academy, where 10,000 to 20,000 robots will practice a wide range of tasks and feed what they learn into the next version of the model. Every unit off the Fremont line becomes a source of that training data.
Smarter hardware is on the way too. Tesla plans to put its AI5 chip into Optimus next year, and Musk said a new Optimus video should arrive within one or two months showing the robot completing tasks driven by AI rather than preprogrammed motions. He took aim at rival humanoid demos that only run scripted routines, saying those would not hold up in the real world.
The supply chain is lining up behind the program. In September, Tesla certified Tuopu, Joyson and Sanhua as mass production partners for Optimus components. A far larger Optimus factory is also rising at Giga Texas, where drone footage from Joe Tegtmeyer showed the steel frame nearing completion, and Musk has pegged that plant’s long term target at 10 million robots a year.
Tesla executives also said Optimus production costs are trending toward the expected manufacturing cost of Cybercab, a sign the robot is being engineered for volume from the start. The hands remain the toughest piece of the design, a point Musk also made at the X Takeover event earlier this month, as Teslarati covered at the time, and that is where much of the current engineering effort is focused.

The Starship moon landing number NASA and Elon Musk can’t agree on
Musk disputes NASA estimate of 22 Starship launches for Moon landing, predicting 6 to 8.
Elon Musk is disputing a new NASA safety panel estimate of how many Starship launches it will take to put astronauts on the Moon, saying the real number will be less than half the panel’s figure.
On Thursday, NASA’s Aerospace Safety Advisory Panel held its quarterly public meeting. Panel member Charlie Precourt, a former NASA astronaut, flagged the fueling process for SpaceX’s lunar lander as a major risk for Artemis IV, the mission planned to land a crew on the Moon in 2028. “We need to keep our eyes on numerous required fuelings for the lander,” Precourt said, according to Ars Technica. “I think the last estimate is around 22 flights.”
Ars Technica’s Eric Berger posted the comment on X, and Musk replied. “That’s way too high,” Musk wrote. “Actual number will be more like 6 to 8.”
The disagreement comes down to a basic problem with sending a ship as large as Starship to the Moon. Starship burns nearly all of its propellant just reaching Earth orbit, so it cannot continue on to the Moon without stopping for a refill. SpaceX’s answer is a gas station in space. First, a Starship that works as a storage tank, called a depot, is launched into orbit. Then a series of tanker Starships launch one at a time, dock with the depot and pump their leftover propellant into it. Once the depot is full, the lunar lander version of Starship launches, docks, fills up and heads for the Moon.
Every tanker trip is its own full rocket launch, which is why the count matters. More launches mean more time, more cost and more chances for something to go wrong before astronauts ever leave Earth. Berger estimated that even if SpaceX reaches twice weekly Starship launches by the end of 2027, filling a depot at the panel’s number would still take roughly three months.
How many tankers are needed depends mostly on how much propellant each one can carry to orbit and how much is lost along the way. Starship’s fuel and oxygen are stored at extremely cold temperatures, and some of it slowly boils off while waiting in orbit. More is lost in each transfer. NASA appears to be working from what Starship can lift today, while Musk’s range assumes a more capable rocket.
Musk has pushed back on higher counts before. In 2021, after a government document suggested 16 launches, he called that “extremely unlikely” and said eight tankers would be the most required.
Much of the answer depends on hardware SpaceX has not finished flying. As Teslarati noted earlier this year, the company plans to carry out the refueling process with its upgraded V3 Starship, and Precourt described Artemis IV as carrying “a large number of firsts.” He also praised NASA Administrator Jared Isaacman’s team for working to clear obstacles for both SpaceX and Blue Origin, whose Blue Moon lander does not rely on orbital refueling for its first mission.
