SpaceX converts Falcon Heavy booster into Falcon 9

Published

on

More than two years after the rocket’s last launch, SpaceX appears to have finally decided to give at least one of two surviving Falcon Heavy Block 5 cores a new lease on life as a Falcon 9 booster.

Known as B1052, the Falcon Heavy side core or booster debuted in April 2019 as part of the first flight of the rocket’s Block 5 variant, successfully launching Saudi Arabia’s large Arabsat 6A communications satellite to an almost 90,000 km (56,000 mi) transfer orbit. Following in the footsteps of the first Falcon Heavy, the first Block 5 vehicle repeated its predecessor’s iconic double-landing back at Cape Canaveral. Just 74 days later, both Falcon Heavy Block 5 side boosters B1052 and B1053 launched again, this time supporting the US military’s long-delayed STP-2 rideshare and qualification mission.

Once again, B1052 and B1053 stuck near-simultaneous landings at SpaceX’s Landing Zones. Both missions’ center cores, however, weren’t so lucky. During Arabsat 6A, the first Falcon Heavy Block 5 center core did successfully land but high seas eventually toppled the booster, destroying it and leaving few intact remains. During STP-2, CEO Elon Musk revealed that SpaceX didn’t actually expect to recover the mission’s replacement center core due to the exceptionally hot reentry it would need to survive. As predicted, the center core did not survive, with Musk later reporting that the hot reentry damaged thrust vectoring hardware, causing the rocket to veer off course.

Thankfully, both side boosters aced all four of their collective landings. However, despite previous statements from Musk indicating that Falcon’s new Block 5 design made it fairly easy to convert Falcon first stages between Falcon 9 and Falcon Heavy side booster configurations, both B1052 and B1053 dropped off the face of the Earth immediately after completing STP-2. Only in September 2021, 27 months later, did one of the two cores finally reappear in public – sans landing legs and grid fins but with a nosecone still installed.

As is now clear, that surprise appearance after years in storage was no coincidence. A bit less than three months later after the mystery Falcon Heavy side booster was spotted rolling down a Kennedy Space Center highway from a Cape Canaveral storage hangar to a new SpaceX facility, one of the two side boosters (B1052) was spotted once again – this time with landing legs and a Falcon 9 interstage installed where a nosecone once sat.

Aside from having clearly been converted into a Falcon 9 booster, former Falcon Heavy side booster B1052 was also mated to a new expendable upper stage – a strong indication of an imminent launch. Word on the ground is that the rocket and transporter were on their way to SpaceX’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad for the company’s planned December 18th launch of Turkey’s Turksat 5B communications satellite.

Following SpaceX’s successful NASA IXPE launch on December 9th, the company has two more East Coast launches planned before the end of the year: Turksat 5B NET December 18th and CRS-24 NET December 21st. Several other Falcon 9 boosters (save for B1062, which is probably assigned to CRS-24) are likely available to launch Turksat 5B, so B1052’s assignment – while not implausible – isn’t guaranteed.

Above all else, B1052’s second life as a Falcon 9 is exciting because it means that B1053 probably isn’t far behind it, meaning that SpaceX’s fleet of operational Falcon boosters is about to grow significantly in a short period of time. As of now, that fleet contains eight Falcon 9 boosters that have each completed an average of more than six orbital-class launches. Half have flown nine times. Aside from expanding that fleet by 25%, the reintroduction of B1052 and B1053 will free up SpaceX to retire older boosters like B1049 and B1051, which CEO Elon Musk has said are slower and more expensive to reuse.

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.

Elon Musk roasts India’s billionaire Mukesh Ambani as Starlink fight heats up

Elon Musk sarcastically calls Mukesh Ambani ‘Prime Minister’ as the Starlink India standoff escalates again.

Elon Musk escalated his public fight over Starlink’s launch in India on Friday, addressing Reliance chairman Mukesh Ambani as “Prime Minister Ambani” in a sarcastic post on X. “Please accept my humble apologies for not realizing that you are the real boss of India,” Musk wrote, before accusing Ambani of “monopolistic exploitation” and asking whether he would “consider allowing Starlink to compete.” In follow up posts, he said Starlink has proven essential during natural disasters and would help parts of India with no internet access.

The post came two days into a fight that Musk sparked up on Wednesday, when he said Starlink was “being blocked by certain oligarchs in order to maintain their monopolistic chokehold on the Indian people.” He called it “a crime against the people of India” and left the names out, adding only, “You can guess who they are.” Jio and Airtel together hold more than 80% of India’s telecom market. On Thursday, Musk asked whether Ambani is “the real boss of India” and said Starlink has spent five years complying with “every single law and requirement” of the Indian government.

India’s government has pushed back each time. The Ministry of Communications called the suggestion that its framework is unfair or discriminatory “baseless and misconceived.” Communications Minister Jyotiraditya Scindia said Friday that three companies hold satcom licenses: Starlink, Jio Satellite Communications, and Bharti backed Eutelsat OneWeb. Amazon’s Kuiper, now Amazon Leo, is still going through the process. None can launch until regulators finalize satellite spectrum pricing and the Home Ministry signs off on each company’s security compliance. Scindia said the telecom regulator and the Department of Telecommunications are close to a decision on pricing, The Hindu reported. Bharti chairman Sunil Mittal also said OneWeb is still waiting on approvals.

Starlink received its operator license in 2025 after a three year wait, and the space regulator IN-SPACe granted what industry executives called the last approval needed in July. The holdup since then centers on security, particularly concern that foreign operators could bypass Indian gateways.

Musk and Ambani have been on opposite sides of this before. In late 2024, Ambani argued for auctioning satellite spectrum, which Musk criticized as out of step with the rest of the world, and India chose administrative allocation instead. By March 2025, the two sides had signed a deal to sell Starlink devices in Reliance stores, and Starlink secured its telecom license that June. That partner is now also a competitor. Jio is reportedly weighing a constellation of 1,600 to 1,650 satellites costing an estimated $10 billion to $15 billion, while Akash Ambani has told shareholders Jio plans to lease capacity from global providers to move quickly.
