SpaceX’s first thrice-flown Cargo Dragon returns from orbit with Starship tiles intact
After a flawless reentry and splashdown on August 27th, SpaceX’s first thrice-flown Cargo Dragon spacecraft completed its latest mission, arriving in Port of Los Angeles aboard SpaceX vessel NRC Quest.
The successful completion of NASA Commercial Resupply Mission 18 (CRS-18) means that SpaceX is officially the first and only company to launch the same orbital spacecraft three times. Meanwhile, Cargo Dragon capsule C108 also happened to mark the first known orbital flight test of hardware that may be destined for use on SpaceX’s next-generation Starship launch vehicle, taking the shape of four ceramic tiles installed as part of its ablative PICA-X heat shield.
Cargo Dragon’s CRS-18 mission successfully lifted off on its way to the International Space Station (ISS) on July 25th and was berthed to the ISS roughly two days later, completed its delivery of several tons worth of cargo. During the launch webcast, one of the SpaceX hosts noted that black tiles visible on Cargo Dragon’s heat shield – distinct beside its silvery water-sealed PICA-X tiles – were prototypes of a ceramic heat shield material being analyzed for possible use on Starship.
CEO Elon Musk confirmed this after the first launch attempt was scrubbed by weather, stating that SpaceX was looking into the use of “thin [ceramic] tiles” to protect Starship’s windward (atmosphere-facing) half during orbital reentries. Prior to this development, Musk had proposed and posted videos of real-world tests of a steel Starship heat shield concept, in which extra energy could be wicked away by ‘transpiring’ liquid oxygen or methane through microscopic holes on each tile’s leading edge.
Although particular species of stainless steel do feature exceptionally high melting points and structural characteristics at ultra-high temperatures (> 1400C/2500F), some unofficial analyses of the numbers involved indicated that the density and weight of steel could rapidly hinder any benefits derived from its use as a heat shield. Musk appeared to confirm this in his July 24th comments, indicating that thin ceramic tiles on the windward side and nothing on the leeward side of Starship looked like the “lightest option”.

Indeed, ceramics were so prevalent on the Space Shuttle – the only semi-routinely reusable space plane ever developed – in large part because they can be made spectacularly light. The Shuttle’s main ceramic tiles had a density of 155 kg/m³ (9 lb/ft³), about five times denser than styrofoam or roughly the same density as freshly-fallen snow and balsa wood. Stainless steel is about 50 times denser, on average. To use Musk’s own 2017 turn-of-phrase, adding thick steel tiles to Starship’s already-steel skin was probably a bit too much like “building a box in a box”, whereas prioritizing ceramic tiles presumably cuts the shield’s mass by a factor of something like 20-100+.
Although the Shuttle did make extensive use of ceramic shielding, that shielding – specifically, reinforced carbon-carbon (RCC) tiles about as fragile as the material people are familiar with – and a mixture of organizational ineptitude infamously lead to the death 7 NASA astronauts and was generally a nightmare to deal with. SpaceX certainly won’t have to deal with the foam and solid rocket boosters that a lot of Shuttle’s ceramic problems can be traced to, but the company will likely be laser-focused on producing a form of ceramic shielding that isn’t nearly as fragile as Shuttle-derived materials.
The fact that Cargo Dragon’s ceramic Starship tile prototypes appear to be almost completely unscathed after their first orbital reentry is an excellent sign that SpaceX is making progress in the materials design and certification department, or is at least taking flight-testing extremely seriously.
SpaceX CEO Elon Musk is expected to provide an official update on Starship no earlier than late September, a presentation that will likely include details about the route the company is taking with the massive spaceship’s heat shielding.

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.
Dear Prime Minister Ambani,
Please accept my humble apologies for not realizing that you are the real boss of India.
Naturally, you would prefer to maintain your monopolistic exploitation of the great people of India, but would you nonetheless consider allowing Starlink to compete?
There are many areas of India, as there are in all countries, with no Internet access, which denies children the opportunity for education and for small businesses the opportunity to sell their goods to a global market. Starlink would change their lives for the better.
Thank you 🙏

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.

Elon Musk’s surprise addition to the X Takeover lineup has fans talking
Elon Musk will join Saturday’s X Takeover at Giga Texas for a live virtual interview.
Elon Musk will join X Takeover at Giga Texas on Saturday for a live virtual interview, according to Sawyer Merritt, who shared the news late Thursday. Musk will not be on stage in Austin. The conversation is set to stream for free on the @teslaownersSV account on X.
Organizers had kept expectations in check. In a September update, Tesla Owners Silicon Valley said Musk had appeared at the event twice before but was not promising a third appearance, even as fans hoped he would walk the Giga Texas grounds in person. A virtual spot matches 2024, when Musk gave a surprise interview of about an hour to the crowd in San Luis Obispo, as Teslarati reported at the time.
Wasn’t expecting this 🫡

This year’s edition is a first in several ways. It is the first X Takeover held outside California and the first at a Tesla facility, with tickets selling out in eight days. Tesla provides the venue, but the event is produced independently by Tesla Owners Silicon Valley. The main event runs from 10 a.m. to 6 p.m. CT, followed by a drone and light show at 9 p.m. Maye Musk is the keynote speaker, Franz von Holzhausen is set for a virtual keynote, and Nicki Minaj is the special guest. Joe Tegtmeyer, whose drone footage Teslarati used to track the Optimus factory steel frame at Giga Texas, is also on the speaker list.
Musk’s interview topics have not been revealed, but the backdrop is busy. Tesla doubled its Cybercab fleet in Austin in late September, and last week Musk explained why Robotaxi hours only moved from 10 p.m. to 11 p.m.. Merritt also reported Thursday that Texas DMV records now show 319 registered Cybercabs, up from 169. NHTSA’s deadline for Tesla’s sworn answers on Cybercab certification is October 30, and Tesla reports third quarter earnings on October 21.
Fans who cannot make it to Austin can watch the livestream on X. Musk tends to say more in unscripted settings than he does in prepared remarks, which is the reason this one is worth having open on Saturday.
