SpaceX Falcon Heavy rocket celebrates 4th launch debut anniversary
On the fourth anniversary of SpaceX’s Falcon Heavy launch debut and after an unusual multi-year hiatus, the world’s most powerful operational rocket could be on the brink of an impressive salvo of launches.
Four years ago yesterday, on February 6th, 2018, Falcon Heavy lifted off from NASA’s historic Kennedy Space Center (KSC) Pad 39A launch complex, launched a truly esoteric payload into interplanetary space, and officially became the largest, heaviest, and most powerful active launch vehicle in the world. It also became the third most powerful liquid rocket ever launched, placing SpaceX squarely at the table alongside the likes of NASA’s Saturn V Moon rocket and the Soviet Union’s ill-fated N-1 and Energia.
14 months later, an upgraded “Block 5” version of Falcon Heavy aced two more back-to-back launches in April and June 2019, completing its first missions for paying customers and also aiding the US Air Force in its efforts to certify the capable rocket for high-value military launches. However, such an auspicious beginning made the years of inactivity that immediately followed Falcon Heavy’s third launch even more striking.
Since Falcon Heavy’s late-June 2019 launch of the USAF’s Space Test Program 2 (STP-2) mission, the rocket hasn’t launched once. That wasn’t supposed to be the case. As of June 2018, SpaceX was supposed to launch the US Air Force’s AFSPC-52 (now USSF-52) mission in September 2020. In June 2019, Spaceflight Now reported that USSF-44 – not USSF-52 – would be SpaceX’s next Falcon Heavy launch and was expected no earlier than (NET) “late 2020.” By September 2020, USSF-44 was expected to launch in February 2021. By February 2021, the US military stated that USSF-44 was scheduled to launch NET October 2021. By October 2021, the US military had once again delayed USSF-44 to early 2022 and USSF-52 to “Q2 2022.”
While the military has done little more than acknowledge each new date, it has vaguely implied that the spacecraft – not SpaceX – are to blame for the chronic, prolonged delays. Without even a hint of an explanation, it’s unclear if those delays are likely to end anytime soon, potentially delaying USSF-44 and USSF-52 into the second half or last quarter of 2022 and pushing USSF-67 into 2023. Thankfully, unreliable US military payloads aren’t the only Falcon Heavy missions scheduled this year.
At a minimum, SpaceX is contracted to launch the ViaSat’s first of three next-generation ViaSat-3 communications satellite directly to geostationary orbit (GEO). The launch was recently delayed from Q2 to the end of Q3 2022. SpaceX is also scheduled to launch NASA’s Psyche mission – a spacecraft designed to visit and study an asteroid made almost entirely out of metal – NET August 2022. While customer Inmarsat has yet to finalize or announce a contract decision, Falcon Heavy could potentially be tasked with launching the second Inmarsat-6 geostationary communications satellite sometime later this year.
All told, if every customer is able to stem each torrent of delays, Falcon Heavy could feasibly launch five or even six times in 2022. More conservatively, if USSF-67 and ViaSat-3 are delayed to 2023 and Inmarsat-6 F2 goes to Falcon 9, the world’s largest operational rocket could still launch three times in 2022 and still have up to three more launches scheduled next year.
For now, Falcon Heavy’s first launch in at least 33 months and fourth launch overall isn’t expected until March 2022 at the earliest.
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.
