SpaceX fires up sooty Falcon booster ahead of historic astronaut launch
SpaceX says it has successfully completed the last major test standing between a flight-proven Falcon 9 rocket and Crew Dragon spacecraft and the company’s next historic astronaut launch.
Right on schedule, once-flown Falcon 9 booster B1061, orbit-proven Crew Dragon capsule C206, and a new expendable Falcon upper stage rolled out to Kennedy Space Center (KSC) Launch Complex 39A on Friday, April 16th, kicking off the last major steps for SpaceX’s second operational astronaut launch. Captured in great detail by NASA and SpaceX photographers, the rollout was completed without issue and the rocket was brought vertical and connected to the launch pad later the same day.
Less than 24 hours later, the fully integrated Falcon 9 was loaded with supercooled liquid oxygen and rocket-grade kerosene (RP-1) and ultimately fired up its nine first-stage Merlin 1D engines – a procedure virtually identical to a normal launch flow. All systems thus fully checked out and cleared for flight, SpaceX and NASA proceeded into a “dry dress rehearsal” early on Sunday.
Much like the Saturday static fire replicated almost every rocket-related aspect of launch, Sunday’s ‘dry dress’ served a similar role for the mission’s human elements – an international group of astronauts and the SpaceX and NASA teams that prepare them for flight. For Crew-2, Falcon 9 and Crew Dragon will be carrying Japanese (JAXA) astronaut Akihiko Hoshide, European (ESA) astronaut Thomas Pesquet, and NASA astronauts Shane Kimbrough and Megan McArthur.
Those four astronauts will be flying on Falcon 9 booster B1061, already responsible for launching Crew Dragon’s operational debut in November 2020, making Crew-2 the first time in history that astronauts will fly on a flight-proven liquid rocket booster and flight-proven private rocket of any kind.
(Quite literally) on top of that, they will also be riding in the Crew Dragon capsule responsible for enabling the United States’ first orbital human spaceflight launch in almost a decade less than a year ago. Dragon C206 successfully launched NASA astronauts Bob Behnken and Doug Hurley to the International Space Station (ISS) in late May 2020 and flawlessly returned them back to earth in early August, acing the first crewed US spaceflight since the Space Shuttle’s premature July 2011 retirement.
That means that Crew-2 will make Crew Dragon C206 the first crewed space capsule in history to launch astronauts more than once – a truly historic achievement but just the latest in a long line of successful uncrewed Dragon reuses over the last four years. That NASA – a famously risk-averse spaceflight agency – is at all willing to allow its astronauts to fly on a flight-proven Dragon or Falcon 9 booster is impressive and was perceived as a highly improbable outcome just a few years ago.
For NASA to allow SpaceX to perform both feats of unprecedented crewed rocket and spacecraft reuse on Dragon’s third human spaceflight ever is nothing short of the most resounding endorsement and validation of the company’s technical expertise that the space agency could ever offer. Thanks in large part to NASA’s flexibility and seemingly boundless confidence in SpaceX, the company has been able to expedite its astronaut launch plans in order to prevent major delays hampering Commercial Crew Program’s other partner – Boeing – from disrupting NASA’s presence on the ISS.
Falcon 9 is scheduled to launch Crew-2 no earlier than (NET) 6:11 am EDT (10:11 UTC) on Thursday, April 22nd.
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.
Tesla launched the all-electric, steering wheel-less, and pedal-less Cybercab last night at a quiet and small event in downtown Austin, Texas.
The launch, which marked the beginning of unsupervised ride-hailing for Tesla’s Robotaxi platform with Cybercab, has already caught the attention of the National Highway Traffic Safety Administration (NHTSA) who has more questions.
NHTSA opened an Audit Query (AQ) into the Cybercab’s Federal Motor Vehicle Safety Standards (FMVSS) certification that Tesla gave the vehicle. Manufacturers self-certify vehicles much of the time to avoid excessive regulatory delays.

However, the agency needs more information; it said in a summary:
“On September 3, 2026, Tesla began commercial deployment with a small number of its Cybercab vehicles in Austin, Texas. Tesla notified the Agency that it certified those Cybercab vehicles as compliant with all applicable Federal Motor Vehicle Safety Standards (FMVSS). Tesla also notified the Agency that it plans to gradually expand commercial deployment of the Cybercab to include additional vehicles and locations.”
It also went on to state that the Cybercab lacks traditional automotive controls, which is a groundbreaking move. The process is entirely new to the NHTSA, which gives the agency some leverage to put Tesla’s launch under a microscope:
“The vehicles lack permanently attached, conventional manual controls, such as a brake pedal, gas pedal, steering wheel, and mirrors. NHTSA is opening this AQ to examine the process and technical data on which Tesla relied when certifying the Cybercab and related issues. Among other things, NHTSA will consider the extent to which Tesla’s certification depended on determinations that certain FMVSS are inapplicable to the Cybercab.”
Tesla has added 45 Cybercab units to its fleet of Robotaxi-enabled cars in Austin, according to public documents the company submitted to the State of Texas over the past week. Enabling this level of self-driving is something Tesla has worked toward for many years, and now that it is finally here, it seems more than reasonable that regulatory agencies will have some questions.
Many outlets might try to frame this as a negative, but it is truly an agency looking to gain more information about groundbreaking tech that Tesla has been developing for years.
In an effort to keep riders, pedestrians, and property safe, any and all data accumulated from these first days, weeks, and months of rides will likely be shared with the NHTSA to enable broader rollout strategies across the United States and more in the future.
