NASA is training SpaceX's first Crew Dragon astronauts for a much longer mission in space
NASA has revealed that the astronauts assigned to SpaceX’s Crew Dragon astronaut launch debut are training for a space station mission many times longer than initially planned.
Scheduled to deliver two NASA astronauts to and from the International Space Station (ISS) no earlier than (NET) late-April or May 2020, Crew Dragon’s Demo-2 mission will be the first crewed launch in SpaceX’s 18-year history. As previously noted on Teslarati (and by NASA itself, briefly), Demo-2 will also mark the first time in history that a privately-built spacecraft attempts to launch humans into orbit.
Still, NASA has funded the development of Crew Dragon (and competitor Boeing’s Starliner) not to achieve firsts but to restore the United States’ ability to launch its own astronauts to the ISS. Along those lines, both Crew Dragon (Demo-2) and Starliner’s (CFT) astronaut test flights were nominally designed to last about a week or two before returning NASA’s astronauts to Earth – a full end-to-end test for both extraordinarily complex vehicles. Two weeks, however, is simply not long enough for those astronauts to practically serve as full members of space station crew, something the ISS generally requires. In response, NASA has been seriously considering extending Boeing’s crewed test flight and has just recently suggested that SpaceX’s own Demo-2 test flight will be similarly upgraded.
About a month ago, SpaceX and NASA talked openly about the possibility of a longer-duration Crew Dragon astronaut launch debut for the first time, potentially extending the amount of time those astronauts are able to spend at the space station from about one week up to 1.5-3 months. This would allow Crew Dragon’s Demo-2 NASA astronauts – Bob Behnken and Doug Hurley – to serve as full members of the ISS crew, expanding the US presence from one to three astronauts.
Ars Technica’s Eric Berger offered some additional details about what exactly NASA might task Behnken and Hurley with on an extended flight earlier this month. Most importantly, the space agency wants the former astronaut – a Space Shuttle and extra-vehicular activity (EVA) veteran – to be (re)trained for spacewalks, allowing him to support an ever-growing to-do list of critical space station repairs and upgrades.
In effect, extending Crew Dragon’s astronaut flight test will make it almost identical to an “operational” flight where Crew Dragon ferries astronauts to the space station, docks for about six months, and finally returns the same astronauts to Earth at the end of its mission. More importantly, though, NASA’s decision to extend Commercial Crew Program (CCP) test flights – kickstarted with Boeing’s beleaguered Starliner spacecraft – is motivated by a desire to prevent the United States’ presence on the space station from dwindling or even regressing to zero in the near future.
Triggered by years of SpaceX and Boeing delays, NASA will now likely have to purchase more seats on Russian Soyuz launches if it wishes to maintain an full, uninterrupted presence on ISS for the next 12-24 months. After suffering numerous deeply concerning software failures on its first and only orbital launch, Boeing’s Starliner is unlikely to be ready to launch crew anytime soon. At the same time, although SpaceX is closer to its astronaut launch debut than ever before, it’s highly unlikely that Crew Dragon can singlehandedly support a full ISS complement of three NASA astronauts while Starliner works out its issues.
As such, NASA is looking everywhere it can to squeeze a bit more on-orbit time out of existing astronaut missions scheduled in the next year or so, and both Starliner and Crew Dragon’s test flights – barring showstoppers – are excellent opportunities. With NASA Johnson Space Center’s confirmation that both Behnken and Hurley are already deep into the extra training needed for an extended flight, chances are good that both astronauts will be ready for a one- or several-month mission by the time that NASA and SpaceX are ready and willing to launch.

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.
