SpaceX’s most significant US Air Force launch contract yet is set to kick off with a (NET) December 18 launch of the first of 10 next-gen GPS satellites, known as GPS III Space Vehicle 1 (SV01). Thus far, SpaceX has won all five competitive GPS III launch contracts offered thus far by the USAF and – depending on Falcon 9’s performance this launch – could win several more.

Aside from contract victories, SpaceX’s first GPS III launch will be marked by yet another first for the company’s May 2018-debuted Falcon 9 Block 5 rocket. This first is not quite as desirable, though: sans landing legs and titanium grid fins, the new Block 5 booster will be expended after launch and will make no attempt to land.

At this point in time, the first official confirmation that Falcon 9 will be flying in an expendable configuration was given in a handful of comments made by Vice President of Launch and Build Reliability Hans Koenigsmann at a Dec. 5 press conference. While focused primarily on the topic at hand (SpaceX’s successful launch of the CRS-16 Cargo Dragon), members of the press managed to squeeze in a few minimally related questions which Hans graciously answered. Speaking about SpaceX’s imminent GPS III launch, Hans noted that,

“GPS is not landing a booster. It doesn’t have the landing hardware, or the majority of the landing hardware. … I looked at the booster yesterday, it’s in great shape and getting integrated in the hangar.

 

Hans also told members of the audience that he believed the expendable profile had stemmed from a customer (i.e. USAF) requirement based on a need for extra performance:

“Regarding GPS not landing, I think this is a customer requirement to have all the performance for the mission. It’s a challenging mission.“

While there was previously some doubt as to whether Falcon 9 was actually incapable of attempting a booster landing after launch, Mr. Koenigsmann’s offhand suggestion that GPS III launches would be “challenging mission[s]” makes it far more likely that the USAF’s given mission profile genuinely demands all of Falcon 9’s performance – not enough propellant will remain for Falcon 9 to attempt recovery. There is, however, still some ambiguity in Hans’ answer.

If Falcon 9 will be expended solely as a consequence of mission performance requirements despite the oddly low payload mass (~3800 kg) and comparatively low-energy orbit (~20,000 km), the only possible explanation for no attempted recovery would be the need for Falcon 9’s upper stage to perform a lengthy second burn after a long coast in orbit. However, the mission parameters the USAF shopped around for would have placed the GPS III satellite into an elliptical orbit of 1000 km by 20,181 km, an orbit that would unequivocally allow Falcon 9 to attempt a drone ship recovery.

 

The reasoning behind this is simple: SpaceX routinely recovers Falcon 9 boosters after far more energetic launches. For example, Falcon 9’s November 15th launch placed the 5300 kg Es’hail-2 satellite into an orbit of 200 km by 37,700 km, after which Falcon 9 B1047.2 performed its second successful landing on drone ship Of Course I Still Love You. A prevailing second theory for the expendable mission lies in the Air Force’s notoriously stodgy and sometimes irrational revulsion at the slightest hint of risk or change – to minimize perceived risk, the USAF could have thus demanded that SpaceX expend Falcon 9 regardless of whether it was capable of doing so.

For GPS III SV01, it appears that only time will tell whether the satellite ends up in an orbit that can properly explain the booster’s premature demise. Given that SpaceX has a full four additional GPS III launches currently on the books, it will be a shame to see a veritable fleet of Falcon 9 Block 5 boosters tossed into the sea after just a single launch each.

Elon Musk drops a Thanksgiving hint about Starship’s biggest test yet

Elon Musk says Starship Flight 15 will try to catch the ship itself, a first.

Published

Elon Musk says SpaceX’s next Starship flight will try something nobody has done before, by catching the ship itself. Speaking to roughly 2,000 people at the X Takeover event at Giga Texas on Saturday, Musk said Flight 15 is about four to six weeks away and “probably launches a little bit before Thanksgiving, is my guess.”

That is a slip from earlier reporting, which had pointed to a launch as early as October 19. Musk explained why the date keeps moving. “We’re making a bunch of improvements to the rocket between every flight,” he said, adding that there are often hundreds, sometimes thousands, of small changes. This time the list is short, “but some of them take a fair bit of work and we’ve got to go inside the tank to make some of these changes.”

“We’re going to try to catch the ship, which is a super big deal,” Musk said. “If we do so, that’ll be the first time that there’s been full recovery of an orbital class rocket.” SpaceX has already caught the Super Heavy booster with the tower’s mechanical arms, and has talked about catching the ship since late 2025, but the upper stage has never been caught.

Musk also laid out what comes after. “The next big milestone would be to refly both the booster and the ship,” he said, describing a Flight 16 where “all parts of an orbital rocket are reflown.”

The reason SpaceX wants this comes down to cost and cadence. Every Starship ship so far has ended its flight in the ocean, and SpaceX expects most of those water landings to end in fireballs. A ship that returns to Starbase intact can be inspected and flown again. SpaceX’s IPO filing, says Starship V3 is designed to deliver 100 metric tons to orbit in a fully reusable configuration, that SpaceX aims to cut the cost to reach orbit by 99% or more versus the historical average, and that tower catches should allow “multiple launches per day.”

The payoff goes beyond cheaper launches. The next generation Starlink V3 satellites are too large for Falcon 9 and can only fly on Starship, which can carry up to 60 per flight. Flight 14 on September 28 deployed the first 26 of them after Starship reached orbit despite an early engine shutdown, as Teslarati reported. Musk blamed engine computer software, and said the heat shield “was extremely robust,” which he claimed in August had solved Starship’s biggest challenge.

NASA’s Moon plans depend on the same capability. NASA’s inspector general has described a lander mission that needs a propellant depot in low Earth orbit and more than 10 tanker flights, with SpaceX targeting one tanker launch every six days. That schedule only works if ships and boosters come back fast and fly again. Also, ship to ship propellant transfer has not been attempted yet.

One interesting hurdle yet to be explored is bringing the ship back to the launch site, with reentry over land, which will undoubtedly come with a lot of aviation safety reviews.

Tesla’s mirrorless Cybercab will give riders a visibility upgrade

Tesla engineer confirms Cybercab update letting riders pull up rear and repeater cameras on demand.

Tesla is working on a Cybercab update that would let passengers pull up the vehicle’s rear and side cameras on demand, and the request came straight from a rider.

The exchange played out on X late Friday. Cybercab rider Dan Burkland shared photos of the two-seater’s cabin screen after an evening ride, praised the UI team’s work, and left one request: let riders open the rear and repeater cameras whenever they want, “especially for peace of mind.” Tesla UI software engineer Evan (@CarCoder) answered with two words: “In development.”

The idea fits a pattern Teslarati has tracked since public rides began. Days after paid Cybercab service opened in Austin, Tesla sent riders a survey that asked them to rate the touchscreen, the app and the cabin, and to pick the features they wanted most. We reported on that survey in September, and a camera view is the kind of small software change Tesla can push quickly if riders keep asking.

It also speaks to something unique about the vehicle. With no steering wheel, no pedals and no driver, passengers have no mirror to check and no way to see behind them. The hardware is clearly built for camera awareness, from the repeater cameras to the rear camera. Letting a passenger look through those same cameras would give a nervous first time rider a way to confirm what is around the car.

The timing matters because the fleet is growing fast. Tesla’s Robotaxi account said on Saturday that more than 300 Cybercabs are now serving Austin, an eightfold increase in 30 days, and Tesla AI chief Ashok Elluswamy named Dallas as the next city. More cars and more cities mean more people riding in a driverless vehicle for the first time, which is exactly when small trust features carry weight.

For now, the feature is confirmed only as in development. If Tesla follows its usual pattern with Cybercab software, riders could see it appear in a point release without any announcement, and Teslarati will watch for it.

Tesla’s Cybercab fleet jumped 8x in a month, with Dallas up next

Tesla confirms its first official Cybercab fleet number as Austin scales fast and Dallas looms.

Tesla says more than 300 Cybercabs are now serving Austin, the first time the company has put an official number on its active Cybercab fleet. The figure came from the Robotaxi account on X on Saturday, which wrote that one month after launch the service had “scaled to 300+ Cybercabs serving Austin – an 8x increase in 30 days.”

Ashok Elluswamy, Tesla’s head of AI software, quoted the post with a line that carried the bigger news. “Two years since the 10/10 Cybercab WeRobot event, the cabs are everywhere in Austin now. Dallas soon,” he wrote. It is the first time Tesla has named the next city for public Cybercab rides.

Tesla opened Cybercab rides to the public in Austin on September 4, as Teslarati reported, a day after an invite only launch event. The ramp since then has been steep. Our September 28 report had the fleet at well over 100 units after availability jumped from 58 to 125 in a single week. On Thursday, Tesla added 150 Cybercabs to the Texas automated vehicle registry, lifting its registered count to 319 from 169. The first seven appeared on the registry on August 31.

RobotaxiTracker, a community site that counts vehicles from sightings and state records, listed 275 vehicles in unsupervised service in Austin on Saturday, 105 of them Cybercabs, which is well below Tesla’s figure. Tracker counts can lag official numbers, though Sawyer Merritt noted that Cybercab wait times in Austin stayed short on Saturday evening even with more than 2,000 fans in town for X Takeover.

Regulators are watching the rollout. NHTSA opened an audit query into Tesla’s certification that the Cybercab meets federal safety standards, and sworn answers are due October 30. Tesla reports third quarter earnings on October 21, which gives the company a natural venue to define its fleet numbers and put a date on Dallas.
