SpaceX, NASA finalize contract for second crewed Starship Moon landing
Around eight months after announcing its intention to do so, NASA has awarded SpaceX a contract for a second crewed Starship Moon landing as early as 2027.
Known as Option B, NASA has exercised a baked-in right to modify its Human Landing System (HLS) Option A contract with SpaceX – signed in April 2021 – to extract even more value from investments into the program. In addition to an uncrewed Starship Moon landing planned no earlier than (NET) 2024 and a crewed demonstration that could land two NASA astronauts on the Moon as early as 2025, NASA’s contract modification gives SpaceX the approval and resources it needs to prepare for a second crewed Starship Moon landing.
On top of securing NASA’s Artemis IV mission astronauts a ride to the lunar surface, the Option B contract will also allow SpaceX and NASA to pursue and demonstrate upgrades that will make Starship an even more capable and cost-effective Moon lander.
Update: NASA says that the Option B modification will cost $1.15 billion, raising the maximum value of SpaceX’s HLS contract to approximately $4.2 billion.
When NASA first announced its intention to add a second crewed Moon landing to SpaceX’s existing HLS contract, the agency couldn’t offer specific information about when that landing might occur or which Artemis mission it would be attached to. Part of the reason for that uncertainty was another announcement two months prior that NASA no longer expected a Moon landing to be paired with its Artemis IV (4) mission. And five days after a March 2022 announcement of plans for a second crewed Starship Moon landing, NASA seemingly reaffirmed that there would be a multi-year gap between Starship’s first crewed Moon landing (NET 2025; tied to Artemis III) and NASA’s second crewed Moon landing, which would use an unspecified lander.
But as of November 2022, NASA has thankfully abandoned plans to intentionally allow a gap between Moon landings. SpaceX’s Starship is now on contract to support back-to-back crewed Moon landings NET 2025 and 2027 as part of NASA’s Artemis III and Artemis IV missions. It’s unclear how or why NASA was able to make that change, but it’s a definite improvement over the alternative.
Additionally, NASA will work with SpaceX to debut new capabilities and improvements on Starship’s second crewed Moon landing. While the Artemis III landing will be about as barebones as possible, the Artemis IV Starship will be upgraded with the ability to transport more NASA astronauts (four instead of just two) and more cargo to the lunar surface. It’s not entirely clear, but NASA reportedly wants to land just ~180 kilograms (~400 lb) of cargo with the first crewed Starship, a vehicle likely capable of landing dozens of tons of cargo in addition to several astronauts. NASA hopes that future “sustainable” lander missions, a category that Starship’s Option B landing may or may not fall under, will transport up to one ton (~2200 lb) of cargo to and from the lunar surface.
Finally, the Artemis IV Starship will also be able to dock with NASA’s Lunar Gateway. Gateway is a small deep space station that will be located in a strange, high lunar orbit. It exists almost exclusively to give NASA’s Space Launch System (SLS) rocket and Orion crew capsule a destination they can both reach. The Orion capsule is almost twice as heavy as its Apollo counterpart and its European Service Module (ESM) offers less than half the performance of NASA’s retired Apollo Service Module. Combined, Orion is physically incapable of transporting itself (or astronauts) to the simpler low lunar orbits used by the Apollo Program.
Instead, NASA’s new Moon lander(s) have to pick up Orion’s slack. Starship will be responsible for picking up astronauts in a lunar near-rectilinear halo orbit (NRHO), transporting them to low lunar orbit, and returning them to NRHO in addition to landing on the Moon, spending a week on the surface, and launching back into lunar orbit.
Until it’s modestly upgraded in the late 2020s or 2030s, Gateway will be equally underwhelming. In fact, that’s part of the reason that Starship docking with the Gateway is in any way significant. SpaceX and NASA have decades of expertise docking and berthing spacecraft with space stations. But those spacecraft are typically smaller and lighter than the stations they were joining. Even after the Gateway is fully outfitted with a range of international modules, Starship will likely weigh several times more than the tiny station, making docking even more challenging than it already is.
Starship’s Moon lander variant could also have a cabin with hundreds of cubic meters of habitable space, while the Gateway is unlikely to ever have more than a few dozen. Having a Starship docked would thus immediately make the ultra-cramped station far more livable.
NASA says Artemis IV and the second crew Starship Moon landing will occur as early as 2027. But a ‘space prophet’ who predicted in 2017 that NASA’s SLS launch debut would slip from 2019 to “around 2023” and forecasted that SpaceX alone would win NASA’s Moon lander contract recently told Ars Technica’s Eric Berger that Artemis III, the mission before Artemis IV, is unlikely to launch before 2028. At the time, that source’s predictions verged on blasphemy, but they’ve ultimately proven to be eerily accurate. Only time will tell if their third ‘prophecy’ follows the same path.
Tesla has reached a notable benchmark in its autonomous driving program after its Robotaxi fleet surpassed one million miles of unsupervised operation. The company made the announcement during its Cybercab event in Austin on September 3.
Tesla Vice President of AI Ashok Elluswamy told attendees he was happy to report the fleet had achieved one million miles of unsupervised Robotaxi operation as a testament to safety.
The new total marked a sharp increase from the 380,000 unsupervised miles Tesla disclosed during its second-quarter 2026 earnings update in late July.
In roughly six weeks, the company added about 620,000 miles. That acceleration followed Tesla’s decision to remove in-vehicle safety monitors from most of its operations outside the San Francisco Bay Area.

Tesla first launched Robotaxi service in Austin in June 2025 with safety drivers present. It later began fully unsupervised rides and expanded into Dallas, Houston, Miami, Orlando, and Tampa. The San Francisco Bay Area remains the exception, where a safety monitor still rides in the vehicle under California permitting rules.
The company has not released a city-by-city breakdown of the one million unsupervised miles.
The milestone arrived as Tesla began offering public Cybercab rides in Austin. The purpose-built vehicle has no steering wheel or pedals and is designed only for autonomous ride-hailing. Production versions joined the existing fleet of modified Tesla vehicles already operating in the service.
Tesla’s unsupervised mileage is growing at a double-digit weekly rate according to earlier company comments, yet its fleet size remains modest compared with established competitors. Waymo has accumulated more than 200 million fully autonomous rider-only miles. Tesla has described its own unsupervised operations as having recorded zero notable incidents in the period leading up to the July update.
The one-million-mile figure reflects Tesla’s shift from supervised testing to broader driverless service in multiple states. It also highlights the company’s strategy of using both existing Model Y vehicles and the new Cybercab to scale its network.

Whether the rapid recent growth continues will depend on further city expansions, regulatory approvals, and the performance of the purpose-built Cybercab in everyday paid rides. Tesla has not specified how many of the latest miles involved the new vehicle versus the rest of the fleet.
The announcement underscores Tesla’s progress toward a larger robotaxi network while illustrating the remaining gap in total autonomous experience relative to longer-operating rivals.
Tesla AI lead Ashok Elluswamy said this week that 24-hour Robotaxi service is close. Replying on X to a rider who wanted Cybercab trips all night, he wrote that the capability would arrive “next month or so” once “the next tech to merge on the v15 plan” is ready.
The comment landed on September 4, one day after Tesla opened public Cybercab rides in Austin. It is the clearest near-term timeline yet for overnight unsupervised operation. Tesla’s paid Robotaxi network currently runs from 6 a.m. to 10 p.m. seven days a week across Austin, Dallas, Houston, Miami, Orlando, and Tampa.
next month or so. the next tech to merge on the v15 plan will enable it.

That 16-hour window is shorter than the 6 a.m. to 2 a.m. schedule the company used for much of the prior year.
Elluswamy did not name the specific feature or say whether the change would apply first to purpose-built Cybercabs, the existing Model Y fleet, or both. He also offered no city-by-city rollout list. The link to Full Self-Driving v15 is nevertheless significant.
Tesla has described v15 as a step-change architecture with seven parallel improvement tracks and roughly ten times more parameters than earlier builds. Early versions of that software already operate on the Robotaxi fleet and contain about 40 percent of the planned gains.
By July 2026, the unsupervised fleet had logged more than 380,000 miles across six cities in two states with what the company called an impeccable safety record and no notable incidents caused by the vehicles themselves. Tesla has repeatedly argued that camera-based end-to-end neural networks, rather than extra sensors, are the core of the solution.
Overnight service would test that claim in lower-light conditions and would also raise vehicle utilization, a key variable for Robotaxi unit economics. The company has already begun using public Superchargers at night and is building dedicated Robotaxi charging sites.
Riders have asked why software must change if the cars already drive in the dark. The practical answer appears to be reliability and scale: Tesla has held back mass expansion until more of the v15 stack is merged, citing the need for higher confidence before putting thousands of unoccupied vehicles on streets around the clock.
If the next module arrives on the timetable Elluswamy sketched, 24-hour service could begin in October 2026 in at least some markets.
That would mark a shift from a daytime-bounded pilot to a service that can run whenever demand exists, including the late-night hours that have so far remained out of reach.
Tesla is beginning to roll out Full Self-Driving Supervised v14.3.9 with a new active safety layer that can take control even when the driver is operating the car manually.
Tesla AI said the software can activate FSD on the driver’s behalf when an imminent collision is detected and Automatic Emergency Braking may not be enough. It may also engage if the system detects heavy distraction or an accidental FSD disengagement.
FSD Supervised v14.3.9 starting to roll out shortly
This release includes a new active safety feature set: FSD Supervised can now activate on your behalf when an imminent collision is detected and Automatic Emergency Braking (AEB) may not be enough.
It may also engage if we…

The capability is essentially Automatic Collision Evasion. However, unlike conventional AEB, which mainly applies the brakes in a straight line, this feature can use steering, braking, and acceleration together if the car calculates that stopping alone will not prevent impact and a safer path exists. The system may change lanes or move toward a shoulder when conditions allow, then continue driving after the immediate threat is handled rather than simply coming to a stop.
The intervention is meant as a last-resort safety net, not a replacement for attentive driving.
Tesla Full Self-Driving v14.3.7 early review: FSD saved me from an accident
Tesla’s own description still frames FSD as supervised assistance. Secondary reports on internal release notes say the feature can fire while the car is being driven manually if cabin-camera monitoring suggests the driver is not sufficiently attentive, such as reaching toward the back seat, or if FSD appears to have been turned off unintentionally.
After the emergency maneuver, the car is expected to alert the driver and request a return to manual control.
The safety case is straightforward. Many collisions happen in the last second because a driver is looking away, fumbles a control, or faces an obstacle that braking cannot fully solve. A system that can both recognize that AEB is insufficient and execute a coordinated evasive path can reduce those remaining high-severity events.
Re-engaging after accidental disengagement also addresses a practical failure mode: a small steering nudge that drops FSD at the worst moment. The advantage is a background safety net that uses the same vision stack already running in v14, instead of leaving the car solely to emergency braking once the driver is no longer in command.
The feature still depends on FSD being enabled and, according to reports, an active FSD purchase or subscription. It does not make the vehicle unsupervised. Drivers remain responsible, and Tesla has not published how often the system is expected to intervene or how it will handle false positives.
If the rollout is conservative and the false-alarm rate stays low, the update is a meaningful step: FSD is no longer only a feature the driver turns on. In the rare moments when disaster is already forming, it can step in.
