SpaceX’s first Falcon Heavy launch in two years is finally coming together
For the first time in more than two years, SpaceX’s next Falcon Heavy launch and dual-booster landing appears to be right around the corner – and it comes with a catch.
In February 2018, after years of anticipation, SpaceX successfully launched its triple-booster Falcon Heavy rocket for the first time in a spectacular show of force. Though the ‘center core’ booster got a little melty on its extremely high-speed reentry and was lost before it could attempt to land, the rocket’s twin side boosters performed an iconic near-simultaneous landing just a handful of miles away from where they lifted off.
Then Falcon Heavy took a good, long break. Ultimately, it would turn out that the debut vehicle was effectively a one-off and over the course of 14 months, SpaceX fairly quickly designed, built, and qualified an entirely new Falcon Heavy rocket based on Falcon 9’s new and improved Block 5 variant. In April 2019, after a few minor delays, that Falcon Heavy Block 5 rocket completed its own launch debut and first mission for a paying customer. This time around, all three boosters – two by land and one by sea – survived reentry and performed flawless landings on a drone ship and two Landing Zones.
A mere two months later, both of Falcon Heavy Block 5’s first two recovered side boosters flew again in support of the US Air Force’s STP-2 mission – a combined demonstration flight and rideshare mostly designed to push the rocket to its limits and help the military qualify it for high-value payloads. Once more, those side boosters successfully returned for a simultaneous landing at SpaceX’s Landing Zones but the mission’s Block 5 center core’s reentry was – as SpaceX itself partially expected – too hot, burning essential components and resulting in a hard ‘landing’ in the Atlantic Ocean. Otherwise, the mission was a spectacular success and gave the US military practically all the data it needed to qualify the world’s largest operational rocket to launch its payloads.
Shockingly, however, that June 2019 launch would end up being Falcon Heavy’s third and latest. In the almost 26 months since, the rocket hasn’t flown once. Originally scheduled to launch a fourth time as early as Q4 2020, the COVID-19 pandemic ultimately delayed the rocket’s next two launches (or gave the satellite manufacturer(s) perfect scapegoats for technical delays) into 2021.
Known as USSF-44 and USSF-52 (formerly AFSPC-44/52), both missions are scheduled to launch ethereal US military spy and/or communications satellites. USSF-44 is arguably the most important, as it will mark SpaceX’s first direct launch to geostationary orbit (GEO) for any customer – let alone one as exacting as the US military. USSF-52 is a much simpler and more traditional launch to an elliptical geostationary transfer orbit (GTO).
About a year ago, for unknown reasons, the two missions swapped positions, with USSF-44 taking the lead. Expected to launch in June 2021 as of early this year, SpaceflightNow first reported that USSF-44 had slipped further still to October – and USSF-52 into 2022 – this May. Since then, that’s where the mission’s schedule has tentatively lain.
Finally, on August 12th, SpaceX filed an FCC application for rocket communication permissions. While otherwise ordinary, this particular request stated that it was for Falcon Heavy recovery operations and, more specifically, for the simultaneous recovery of two Falcon Heavy boosters at sea. Out of an abundance of caution and conservatism and combined with the generally challenging nature of direct-to-GEO launches, Falcon Heavy’s first such mission for the US military will require SpaceX to expend the rocket’s center booster and recover both side boosters at sea with two separate drone ships.
Falcon Heavy’s USSF-52 GTO launch isn’t as demanding and its mission profile is expected to allow SpaceX to recover all three boosters. As such, an FCC filing for a dual-drone-ship Falcon Heavy side booster recoveries practically guarantees that it’s for USSF-44. Per the application, SpaceX expects the mission to occur no earlier than September 25th. Almost simultaneously, launch photographer Ben Cooper also updated a long-running list of upcoming East Coast launches, confirming that Falcon Heavy’s fourth launch (USSF-44) remains on track for October 2021.
Ultimately, while delays are possible and likely probable, there now appears to be a strong chance that Falcon Heavy will launch for the first time in 28 months before the end of 2021.
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.
