SpaceX Starlink satellite constellation aims to become world’s largest after next launch

Published

on

In a sign of things to come next year, SpaceX’s next – and third – 60-satellite Starlink launch is officially on the books, and – if all goes as planned – could make the company the proud owner of the world’s largest operational satellite constellation.

On May 24th, Falcon 9 lifted off for the first time ever on a dedicated Starlink launch, placing 60 ‘v0.9’ prototype satellites in Low Earth Orbit (LEO), where they deployed solar arrays and fired up their own electric krypton thrusters to reach their operational ~550 km (340 mi) orbits. Of those 60 prototypes, several were intentionally deorbited while another handful suffered unintended failures, while 51 (85%) ultimately reached that final orbit and began operations.

Previously expected in mid-October, unspecified delays pushed SpaceX’s next Starlink launch – deemed Starlink-1, the first launch of ‘v1.0’ satellites – into November. On November 11th, Falcon 9 B1048 and a flight-proven payload fairing lifted off with 60 more Starlink satellites, also marking the first time a Falcon 9 booster completed four orbital launches and the first operational reuse of a recovered fairing. Upgraded with four times the overall bandwidth, improved structures, new Ka-band antennas, and more steerable ‘beams’ on each of those antennas, those 60 Starlink v1.0 satellites rapidly came online and began raising their orbits.

This time around, SpaceX received FCC approval to test satellites at a substantially lower altitude of ~350 km (220 mi) and launched to a parking orbit of just 280 km (175 mi), ensuring that any debris or failed spacecraft will reenter Earth’s atmosphere in just a matter of months while also completely avoiding added risk to the International Space Station (ISS) (~400 km). After a brisk ten or so days of active propulsion, 55 of those 60 satellites have raised their orbits to ~350 km, while ~20 of those 55 appear to be aiming for a final altitude somewhat higher, likely the start of a separate orbital plane.

The moment that Starlink-1 satellites began to arrive and stabilize at their 350-km operational orbits, nearly all of SpaceX’s 50 operational v0.9 satellites began lowering their orbits, potentially signaling a move down to Starlink-1’s operational altitude, or even an intentional deorbit of the entire prototype tranche (far less likely).

From nothing to #1

The same day that several dozen Starlink-1 satellites finished the climb up to their operational orbits, SpaceX announced media accreditation for its next Starlink launch, presumed to be Starlink-2. According to SpaceX, the mission is targeted for the last two weeks of December 2019, a schedule that will tighten as it gets closer. Previously expected to launch in early November, as few as two weeks after Starlink-1, Starlink-2 has suffered similar delays but still appears to be on track for 2019.

It’s assumed that Starlink-2 – like both dedicated missions preceding it – will launch 60 Starlink satellites. If that is, in fact, the case, the mission could mark a surprising but fully-expected milestone: with >170 functional satellites in orbit, SpaceX might become the proud owner of the world’s largest operational satellite constellation. Excluding two Tintin prototypes launched in February 2018 and 8 failed Starlink v0.9 spacecraft, a perfect Starlink-2 launch would raise SpaceX’s operational constellation to 172 satellites.

The only satellite operator anywhere close to those numbers is Planet Labs, an Earth observation analytics and satellite production company that has launched >400 satellites in its lifetime. Of those ~400 spacecraft, it’s believed that ~150 were operational as of October 2019 and Planet has another 12 Dove observation satellites scheduled to launch on November 27th. In simple terms, this means that SpaceX may become the world’s largest satellite operator after Starlink-2 and it all but guarantees that that will be the case after Starlink-3, a mission that will likely follow just weeks later.

Once SpaceX passes that milestone, it’s all but guaranteed that Starlink will retain the title of world’s largest satellite constellation for the indefinite future. According to SpaceX COO and President Gwynne Shotwell, as many as 24 Starlink launches are planned for 2020, and SpaceX’s burgeoning Washington-state satellite factory may soon be capable of supporting the unprecedented volume of production such a cadence will require. Even assuming rocky development, it’s hard to picture SpaceX’s next-generation Starship rocket taking more than two additional years to be ready for routine orbital missions to LEO, each of which should be able to place 400 Starlink satellites in orbit.

OneWeb is by far the closest thing SpaceX has to a serious Starlink competitor and its first operational launch of ~30 satellites has recently suffered delays, moving from December to late-January or February 2020. Roughly monthly launches (each with ~30 satellites) will nominally follow that first launch. After Starlink-2 or Starlink-3, the only conceivable ways that SpaceX could ever lose the title of world’s largest satellite operator would require catastrophic failure(s) grounding Falcon 9 and/or Starship for >1 year or outright bankruptcy and liquidation, neither of which seem particularly likely.

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.
