Update: SpaceX has successfully wrapped up the Radarsat Constellation Mission, likely its last launch from Vandenberg Air Force Base for six to nine months. Supporting its second mission, Falcon 9 booster B1051 completed a flawless launch and landing, returning to SpaceX’s pad-adjacent LZ-4 landing zone after a gentle, (relatively) low-velocity reentry at ~1.6 km/s (3700 mph).

Sadly, the sun was unable to beat back Vandenberg’s iconic fog layer and it’s unlikely that remote cameras (even including SpaceX’s own on-pad webcast cameras) captured anything more than gray fog. According to Teslarati’s photographers, the sonic booms produced by the returning Falcon 9 booster were as spectacular as ever, though.

Despite more than seven months of delays, the Canadian Space Agency (CSA) can finally rest now that all three Radarsat Constellation spacecraft are safely in orbit, completing what is arguably the most arduous leg of most spacecraft journeys. Valued at more than $1 billion, SpaceX has also successfully launched its most expensive payload by a large margin, adding to Falcon 9’s increasingly impressive record of reliability.

SpaceX is just hours away from its sixth Falcon 9 launch of 2019, likely the company’s last Vandenberg Air Force Base (VAFB) mission for the rest of the year (and possibly longer).

Flight proven Falcon 9 booster B1051.1 has been assigned to the launch and will attempt to return to SpaceX’s LZ-4 landing zone after sending Canada’s Radarsat Constellation Mission (RCM) on its way to orbit. Likely weighing approximately 5000 kg (11,000 lb), RCM is comprised of a trio of Earth observation spacecraft with large surface-scanning radars as their primary payloads. At a cost of more than $1 billion, RCM will be the most expensive payload SpaceX has ever attempted to launch. Falcon 9 has a 13-minute window for launch but liftoff is scheduled to occur at 7:17 am PDT (14:17 UTC) on Wednesday, June 12th.

As it stands, Falcon 9’s RCM launch will last just over one hour from start to finish. B1051 will separate from Falcon 9’s upper stage, fairing, and payload and perform a return-to-launch-site (RTLS) recovery, landing at SpaceX’s LZ-4 pad less than eight minutes after liftoff.

LZ-4 sits barely a quarter of a mile away from SLC-4E, the SpaceX-leased pad that B1051.1 will lift off from. Sadly, B1051 is unlikely to remain at SLC-4 after its (hopefully successful) landing at LZ-4 due to the fact that SpaceX has no public missions scheduled to launch from VAFB until Q1 2020 at the earliest. In fact, SpaceX is reportedly planning major organizational changes – set to begin soon after this launch is complete. As such, RCM could be SpaceX’s last launch from California for at least the next six months, a period of downtime that could easily grow to a year or more if tenuous 2020 launch dates suffer payload-side delays.

SpaceX currently has three launches scheduled from its Vandenberg pad in 2020, although one, two, or even all three could easily slip into 2021 based on the limited information available about the payloads in question. In 2021, SpaceX has a fairly busy VAFB manifest of at least six possible launches – possibly more if 2020 missions slip.

Regardless, RCM will be a good temporary send-off to SpaceX’s launch activity in California. Press photographers – unaffiliated with SpaceX – will have the first opportunity ever to remotely capture images of a Falcon 9 booster landing in daylight. Additionally, weather permitting, Vandenberg Air Force Base makes for an exceptionally beautiful venue for rocket launches thanks to the vistas and setting offered by Northern California and the Pacific Ocean.

Current forecasts suggest that the traditional fog layer will begin to clear at 7am local time, around the same time that SpaceX’s RCM webcast will kick off. With any luck, the photographers’ remote cameras will be greeted by a clear Pacific morning come liftoff.

Tesla Cybercabs narrowly miss deadly Amazon cargo plane crash

An Amazon cargo plane crash near Miami’s airport stopped feet from dozens of Tesla Cybercabs.

An Amazon Prime Air Boeing 767 cargo jet overran the runway at Miami International Airport on Sunday afternoon, killing five people and injuring five more. The jet, operated by North Carolina based carrier 21 Air as Flight 7598, touched down around 2 p.m. after arriving from San Juan, Puerto Rico, then crossed the airport perimeter, plowed across NW 67th Avenue and struck multiple vehicles before catching fire, according to the Associated Press.

Photos and video from the scene show the aircraft’s nose stopped within meters of a fenced staging lot holding dozens of gold painted Tesla Cybercabs, the steering wheel free robotaxi Tesla began putting on public roads in Austin last week. Miami-Dade Fire Rescue has confirmed the plane struck “multiple vehicles” but has not said whether any Cybercabs were among them, and neither Tesla nor airport officials have addressed the fleet directly.

The Cybercabs had not yet entered commercial service in Miami. Tesla’s existing Robotaxi operation there runs on modified Model Y vehicles and has been unsupervised since Ashok Elluswamy confirmed the detail on X in July.


Elon Musk offered the briefest of reactions. Replying to a Zero Hedge post about the Cybercabs sitting so close to the wreckage, he wrote a single word: “Weird.” He has not commented further, and Tesla has not issued a statement.

The timing puts Tesla’s newest vehicle near an unrelated but highly visible tragedy just days after its Austin debut, a launch that had already drawn scrutiny from federal regulators. The National Highway Traffic Safety Administration opened an audit how Tesla certified the Cybercab as compliant with federal vehicle safety standards, a process Teslarati covered after the vehicle’s September 3 launch event. That inquiry concerns the car’s lack of a steering wheel and pedals, not the Miami crash.

Investigators from the FAA and NTSB are focused on the plane, not the parking lot beside it. Flight data reviewed by outlets including Simple Flying show the 767 touched down around 170 knots, well above the 135 to 140 knot range typical for the aircraft, though investigators have not determined a cause. Amazon said it is working with authorities and that its priority is the safety of everyone affected.

Whether any Cybercabs were damaged, and what Tesla plans for the fleet parked near one of the country’s busiest airports, remain open questions.

Tesla crosses major Unsupervised Self-Driving milestone

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 Robotaxi will be a 24/7 service: here’s when

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.

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.
