SpaceX Starship prototype returns to factory after simulated Raptor testing

Published

on

A SpaceX Starship prototype that could become the first to launch into space has returned to the company’s Starbase rocket factory after completing a series of thorough proof tests.

Starship S24’s test campaign got off to a rough start when the roughly nine-meter (30 ft) wide, 50-meter (~165 ft) tall rocket blew a high-pressure pipe during its very first test – a generally benign ‘pneumatic proof.’ While it appears that most of the ship passed the test, the burst pipe damaged a section of the heat shield and took several days of continuous work to repair and replace. With that hiccup behind it, however, Ship 24 appears to have performed excellently during the next two phases.

On June 1st, the ship fully passed pneumatic proof testing on the second try. On June 2nd, it completed its first cryogenic proof test, referring to the process of filling and pressurizing Starship’s tanks with liquid nitrogen – ultra-cold like its methane and oxygen propellant but without the risk of fire or explosion. Once the basics were out of the way, Ship 24 was cleared for installation on one of two of SpaceX’s suborbital Starship test and launch pads. Over the course of about two months, Pad A was significantly modified both to support Ship 24’s upgraded design and to put it to the test by using giant hydraulic rams to simulate the thrust of Raptor engines.

Ship 24 was installed on the modified mount on June 4th, just 12 hours after completing its first cryoproof. On June 6th and 7th, SpaceX then put the prototype through another pair of cryogenic proof tests, both of which appeared to be completed without issue on the first try. The first test even saw Ship 24 use its nose vents, suggesting that SpaceX may have filled and pressurized both its main tanks and a smaller pair of landing propellant or ‘header’ tanks.

At some point during either or both of the Pad A cryoproofs, it’s believed that the mount’s hydraulic rams were used to test Ship 24’s upgraded aft end by simulating the thrust of six Raptor engines. Like Ship 20, Ship 24 will eventually be outfitted with three smaller sea level-optimized Raptors and three larger vacuum-optimized Raptors. However, Ship 24 will be the first Starship to use new Raptor 2 engines, which are capable of generating almost 25% more thrust. At full throttle, Ship 24 could theoretically produce almost 1400 tons (~3.1M lbf) of thrust at sea level, just shy of twice the thrust of an entire Falcon 9 booster. Starship will be the most powerful orbital spacecraft in history.

First, though, the rocket needs engines. After completing all three cryoproof tests without apparent issue, SpaceX removed Ship 24 from Pad A and transported it back to the Starbase factory on June 9th. While it’s not actually clear if those tests were fully successful, the general assumption is that SpaceX returned the prototype to the factory to fill gaps in its heat shield; complete its aerocovers and raceway; and, most importantly, install six Raptor 2 engines.

If that is the case, Ship 24’s second trip to the launch site could be for wet dress rehearsal and static fire testing – a campaign that could ultimately qualify the ship for Starship’s first orbital launch attempt.

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.
