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 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.
