SpaceX to launch ninth batch of Iridium NEXT satellites
Iridium Communications has chosen SpaceX to launch one last batch of its NEXT communications satellites, rounding out the constellation with up to five more on-orbit spares.
The company says that SpaceX’s Falcon 9 rocket will launch those satellites as part of a rideshare mission that is scheduled to lift off from California’s Vandenberg Space Force Base (VSFB) no earlier than mid-2023.
Iridium and SpaceX have had a close relationship for as long as Falcon 9 has been flying. In 2010, days after Falcon 9’s first successful launch, the company – led by CEO Matt Desch – awarded SpaceX a head-turning contract worth almost $500 million for the launch of the entire Iridium NEXT constellation. SpaceX kicked off Iridium NEXT launches in early 2017, returning to flight after a Falcon 9 rocket exploded on the launch pad just four months prior.
Less than two years later, SpaceX had completed eight Falcon 9 launches for Iridum and successfully deployed the full 75-satellite NEXT constellation (up from initial plans for 72 satellites) in polar orbit. Now, after what will be a four-and-a-half-year hiatus of joint activities, Iridium wants SpaceX to launch up to five of the six remaining NEXT spares, meaning that Falcon 9 will likely be responsible for launching all but one satellite of the constellation.
When SpaceX completed its eighth and (at the time) final Iridium launch in January 2019, the communications provider was left with nine NEXT satellite spares in orbit and six spares on the ground – all ready to take over (or be launched) in the event of an anomaly. Built by Thales Alenia Space, those satellites – built and launched for approximately $2.9 billion – have proven exceptionally reliable. Close to six years after the first launch, none of the 75 satellites currently in orbit have failed.
Iridium isn’t launching the six remaining ground spares because it needs them, in other words. On top of nixing the cost of storing satellites for years, Iridium’s CEO says that launching those spares now will “make [the NEXT] network even more resilient.” Prior to the September 8th announcement, Iridium’s Q2 2022 earnings report revealed a $35 million contract to launch five of the six remaining NEXT spares – almost certainly referring to its ninth SpaceX launch. Accounting for inflation, Iridium paid SpaceX approximately $8.9 million in 2022 dollars for each of the first 75 NEXT satellites it launched. For its ninth SpaceX launch, Iridium will pay $7 million – 21% less.
In 2020, Iridium signed a nonbinding agreement with startup Relativity Space to potentially launch all six spares on its 3D-printed Terran 1 rocket. Two years later, it appears that Iridium has mostly changed its mind, and no longer wants to worry about launching its NEXT spares “on an as-needed basis.” With a list price of $12 million, Terran 1 would only be able to launch one 860-kilogram (1900 lb) Iridium NEXT satellite at a time, translating to at least $72 million for all six. As is common for new launch vehicles, Terran 1 has also run into many delays, although Relativity says it could debut as soon as October 2022. It’s possible that Terran 1 could still launch the last Iridium NEXT ground spare, but statements published on Twitter by CEO Matt Desch do not inspire confidence.
Ultimately, Iridium seems to have elected to launch most or all of the remaining spares at once, simultaneously saving tens of millions of dollars and adding additional resiliency to its communications services.
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.
