SpaceX tweaks Starlink Gen2 plans to add Falcon 9 launch option
SpaceX says it has revised plans for its next-generation Starlink Gen2 constellation to allow the upgraded satellites to launch on its workhorse Falcon 9 rocket in addition to Starship, a new and unproven vehicle.
Set to be the largest and most powerful rocket ever flown when it eventually debuts, SpaceX’s two-stage Starship launch vehicle is also intended to be fully reusable, theoretically slashing the cost of launching payloads into and beyond Earth orbit. Most importantly, SpaceX says that even in its fully-reusable configuration, Starship should be capable of launching up to 150 tons (~330,000 lb) to low Earth orbit (LEO) – nearly a magnitude more than Falcon 9. However, once said to be on track to debut as early as mid-2021 to early 2022, it’s no longer clear if Starship will be ready for regular Starlink launches anytime soon.
In August 2021, SpaceX failed a major Starlink Gen2 revision with the FCC that started the company along the path that led to now. That revision revealed plans to dramatically increase the size and capabilities of each Gen2 satellite, boosting their maximum throughput from about 50 gigabits per second (Gbps) to ~150 Gbps. Just as importantly, SpaceX’s August 2021 modification made it clear that the company would prefer to launch the entire constellation with Starship, although it included an alternative constellation design that would lend itself better to Falcon 9 launches.
In January 2022, SpaceX chose to solely pursue the constellation optimized for Starship, strongly indicating that the company believed the rocket would be ready to support Starlink launches in the near future – or at least around the same time the constellation receives its Gen2 FCC license. With the benefit of technical Starlink Gen2 satellite details and renders provided by SpaceX and CEO Elon Musk in Q2 2022, a single Starship Gen2 launch using the current satellite and rocket designs and carrying 54 satellites could potentially deploy around 7-8 times more usable bandwidth than a Falcon 9 with Starlink V1.5, meaning that Starship could achieve similar deployment results with just a few launches per year.
In theory, that makes it at least somewhat easier for Starship to make a major impact even as SpaceX works to ramp up the brand-new rocket’s launch cadence, a task that has almost always taken several years.
However, additional changes made to its Starlink Gen2 FCC license application in August 2022 suggest that SpaceX has at least partially tempered that all-in bet on Starship. The most important modification: developing a different Starlink Gen2 satellite variant that will be optimized to fit inside Falcon 9’s much smaller payload fairing. According to SpaceX, despite the seemingly major form-factor changes required to make Gen2 fit, Starship and Falcon 9-optimized satellites will still be “technically identical.”
The implication is that the satellites launched on Falcon 9 will still offer the same performance as those launched on Starship, albeit in a different form factor. Nonetheless, the only thing SpaceX guarantees in the document is that the Falcon 9-launched Gen2 satellites won’t be more powerful than those launched on Starship, presumably preserving the applicability of existing analysis in the current Starlink Gen2 application. It’s thus possible that Falcon 9-optimized Starlink Gen2 satellites will have to sacrifice some of their performance relative to the unconstrained Starship-optimized variant.
With a usable diameter of 4.6 meters (~15 ft), Falcon 9’s payload fairing is about 50% narrower than the payload bay present on early Starship prototypes. Without a major redesign, Starlink Gen2 satellites optimized for Falcon 9 will likely need to sit vertically inside the fairing, the standard version of which stands 6.7 meters (~22 ft) tall before its conical tip begins curving inwards. Weighing about 1.25 tons (~2750 lb) and measuring 7 meters (~23 ft) long, Starlink Gen2’s design may only need a few moderate tweaks to fit on Falcon 9, but they’ll have to be stacked vertically instead of horizontally. Falcon 9’s established performance of roughly 16.5 tons (payload adapter included) to LEO means that the rocket will be limited to around 12 or 13 Gen2 satellites per launch, however, making the task somewhat easier.
If SpaceX can squeeze that many Starlink Gen2 satellites inside of Falcon 9’s existing reusable fairing, it could still boost the efficiency (total bandwidth per launch) of each Starlink mission by ~50% relative to the same rocket carrying 50-60 Starlink V1.5 satellites. It’s no surprise, then, that SpaceX appears to be doing everything it can to begin launching Starlink Gen2 as quickly as possible, whether or not Starship is ready to help.
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.
