SpaceX set for its most important launch ever as skies, seas threaten delays
SpaceX remains on track for an inaugural NASA astronaut launch that will arguably be the most important single mission in the company’s history, although Florida’s summer weather continues to conspire to delay it.
Heavily dependent on Atlantic Ocean weather conditions, skies (and seas) thankfully appear to be clearing up on the home stretch to Crew Dragon’s Demo-2 astronaut debut. Set to be the first time NASA has launched its own astronauts in nearly a decade and the first time SpaceX (or any private company) has launched humans into orbit, the stakes have never been higher for the 18-year-old Elon Musk venture.
If successful, it will catapult the company into an unprecedented era, proving countless traditional aerospace naysayers wrong and beating the likes of Boeing to the punch — all with a self-built reusable rocket and spacecraft that are dramatically cheaper than their closest competitors. It will be the single most encouraging step SpaceX has taken towards the permanent settlement of the solar system. On the other side of the double-edged sword, if things go south, it’s hard to exaggerate the scale of the setback and road to retribution that would face the pioneering spaceflight company.
Yeah, Atlantic weather review tomorrow morning will determine if we can launch— Elon Musk (@elonmusk) May 27, 2020
For two interconnected reasons, SpaceX’s Crew Dragon astronaut missions are going to be extraordinarily sensitive to weather restrictions come launch day, a fact that has come to partially dominate the tone of Demo-2 preparations over the last few days. First and foremost, NASA’s single highest priority for crewed Commercial Crew Program (CCP) launches is and will continue to be astronaut safety.
If things go according to plan, Crew Dragon’s Demo-2 mission will also be the first time NASA astronauts have splashed down in the ocean since July 1975, when the space agency completed the last launch of an Apollo Command and Service Module (CSM). Recovering crewed spacecraft from the ocean carries numerous challenges and constraints with it, many of which involve specific spacecraft characteristics. For SpaceX and NASA, Crew Dragon will have fairly strict requirements for sea states and weather during astronaut splashdowns. Additionally, thanks to SpaceX’s innovative inclusion of a built-in abort system in the Crew Dragon capsule, the spacecraft will be able to abort at any point during launch, from before liftoff all the way to orbit.
As a direct result of that significant safety improvement, SpaceX and NASA are ironically going to have a more challenging time launching Crew Dragon as dozens of possible abort splashdown locations stretching across the Atlantic Ocean will have to be constantly monitored for weather violations. SpaceX Vice President of Build and Reliability Hans Koenigsmann described the method of weighing those dozens of sites as an extremely complex algorithm, suggesting that unacceptable weather in certain spots might not fully delay a launch opportunity.
Still, adding in the need for SpaceX to attempt to recover Falcon 9 boosters on ocean-based drone ships like Of Course I Still Love You (OCISLY), which carries its own weather restrictions, the company’s astronaut launches are going to be extraordinarily sensitive to environmental factors. As of now, SpaceX’s inaugural astronaut launch remains technically on track to lift off at 4:33 pm EDT (20:33 UTC) on May 27th. The latest forecasts predict a 60% chance of favorable weather on Wednesday, up from 40% around 24 hours ago.
A backup window on May 30th shows a 70% chance of favorable weather, with both days primarily challenged by the likelihood of thunderstorms in and around Cape Canaveral. That forecast, however, doesn’t account for the dozens of locations in the Atlantic Ocean that will also need some level of favorable weather. To quantify the scale of weather-related challenges, Koenigsmann revealed in a prelaunch briefing that the weather component of the flight readiness review (FRR) alone involved a presentation with more than 60 slides. According to Elon Musk, NASA and SpaceX will decide later this morning whether the Atlantic Ocean is calm enough to proceed with Crew Dragon’s historic launch attempt.
SpaceX and NASA will both host livestreams of the Demo-2 mission beginning around noon EDT (16:00 UTC). Stay tuned for updates as we close in on the momentous occasion.

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.

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.
