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.

SpaceX and xAI tapped by Pentagon for autonomous drone contest
The six-month competition was launched in January and is said to carry a $100 million award.
SpaceX and its AI subsidiary xAI are reportedly competing in a new Pentagon prize challenge focused on autonomous drone swarming technology, as per a report from Bloomberg News.
The six-month competition was launched in January and is said to carry a $100 million award.
Bloomberg reported that SpaceX and xAI are among a select group invited to participate in the Defense Department’s effort to develop advanced drone swarming capabilities. The goal is reportedly to create systems that can translate voice commands into digital instructions and manage fleets of autonomous drones.
Neither SpaceX, xAI, nor the Pentagon’s Defense Innovation Unit has commented on the report, and Reuters said it could not independently verify the details.
The development follows SpaceX’s recent acquisition of xAI, which pushed the valuation of the combined companies to an impressive $1.25 trillion. The reported competition comes as SpaceX prepares for a potential initial public offering later this year.
The Pentagon has been moving to speed up drone deployment and expand domestic manufacturing capacity, while also seeking tools to counter unauthorized drone activity around airports and major public events. Large-scale gatherings scheduled this year, including the FIFA World Cup and America250 celebrations, have heightened focus on aerial security.
The reported challenge aligns with broader Defense Department investments in artificial intelligence. Last year, OpenAI, Google, Anthropic, and xAI secured Pentagon contracts worth up to $200 million each to advance AI capabilities across defense applications.
Elon Musk previously joined AI and robotics researchers in signing a 2015 open letter calling for a ban on offensive autonomous weapons. In recent years, however, Musk has spoken on X about the strengths of drone technologies in combat situations.

Doug DeMuro names Tesla Model S the Most Important Car of the last 30 years
In a recent video, the noted reviewer stated that the choice was “not even a question.”
Popular automotive reviewer and YouTuber Doug DeMuro has named the 2012 Tesla Model S as the most important car of the last 30 years.
In a recent video, the noted reviewer stated that the choice was “not even a question,” arguing that the Model S did more to change the trajectory of the auto industry than any other vehicle released since the mid-1990s.
“Unquestionably in my mind, the number one most important car of the last 30 years… it’s not even a question,” DeMuro said. “The 2012 Tesla Model S. There is no doubt that that is the most important car of the last 30 years.”
DeMuro acknowledged that electric vehicle adoption has faced recent headwinds. Still, he maintained that long-term electrification is inevitable.
“If you’re a rational person who’s truthful with yourself, you know that the future is electric… whether it’s 10, 20, 30 years, the future will be electric, and it was the Model S that was the very first car that did that truthfully,” he said.
While earlier EVs like the Nissan Leaf and Chevrolet Volt arrived before the Model S, DeMuro argued that they did not fundamentally shift public perception. The Model S proved that EVs “could be cool, could be fast, could be luxurious, could be for enthusiasts.” It showed that buyers did not have to make major compromises to drive electric.
He also described the Model S as a cultural turning point. Tesla became more than a car company. The brand expanded into Superchargers, home energy products, and a broader tech identity.
DeMuro noted that the Leaf and Volt “made a huge splash and taught us that it was possible.” However, he drew a distinction between being first and bringing a technology into the mainstream.
“It’s rarely about the car that does it first. It’s about the car that brings it into the mainstream,” he said. “The Model S was the car that actually won the game even though the Leaf and Volt scored the first.”
He added that perhaps the Model S’ most surprising achievement was proving that a new American automaker could succeed. For decades, industry observers believed the infrastructure and capital requirements made that nearly impossible.
“For decades, it was generally agreed that there would never be another competitive American car company because the infrastructure and the investment required to start up another American car company as just too challenging… It was just a given basically that you couldn’t do it. And not only did they go it, but they created a cultural icon… That car just truly changed the world,” he said.

Elon Musk doubles down on Tesla Cybercab timeline once again
“Cybercab, which has no pedals or steering wheel, starts production in April,” Musk said.
CEO Elon Musk doubled down once again on the timeline of production for the Tesla Cybercab, marking yet another example of the confidence he has in the company’s ability to meet the aggressive timeline for the vehicle.
It is the third time in the past six months that Musk has explicitly stated Cybercab will enter production in April 2026.
On Monday morning, Musk reiterated that Cybercab will enter its initial manufacturing phase in April, and that it would not have any pedals or a steering wheel, two things that have been speculated as potential elements of the vehicle, if needed.

Musk has been known to be aggressive with timelines, and some products have been teased for years and years before they finally come to fruition.
One of perhaps the biggest complaints about Musk is the fact that Tesla does not normally reach the deadlines that are set: the Roadster, Semi, and Unsupervised Full Self-Driving suite are a few of those that have been given “end of this year” timelines, but have not been fulfilled.
Nevertheless, many are able to look past this as part of the process. New technology takes time to develop, but we’d rather not hear about when, and just the progress itself.
However, the Cybercab is a bit different. Musk has said three times in the past six months that Cybercab will be built in April, and this is something that is sort of out of the ordinary for him.
In December 2025, he said that Tesla was “testing the production system” of the vehicle and that “real production ramp starts in April.
Elon Musk shares incredible detail about Tesla Cybercab efficiency
On January 23, he said that “Cybercab production starts in April.” He did the same on February 16, marking yet another occasion that Musk has his sights set on April for initial production of the vehicle.
Musk has also tempered expectations for the Cybercab’s initial production phase. In January, he noted that Cybercab would be subjected to the S-curve-type production speed:
“…initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast.”
Cybercab will be a huge part of Tesla’s autonomous ride-sharing plans moving forward.
