SpaceX tests ceramic Starship heat shield tiles on Starhopper’s final flight test
Although it flew under the radar in the heat of the moment, SpaceX’s final Starhopper test flight – completed on August 27th – happened to include an unusual bit of test hardware – eight (give or take) ceramic Starship heat shield tiles.
On the same day that Starhopper lifted off for the last time and completed a 150m (500 ft) hop test in South Texas, SpaceX Cargo Dragon capsule C108 wrapped up its third successful orbital mission, reentering Earth’s atmosphere with a complement of several ceramic Starship heat shield tiles. This marked the first known orbital test of Starship hardware on the same exact day that Starhopper was putting nearly identical tiles through an entirely different kind of flight test.
Tile #8
As pictured above, a group of seven hexagonal tiles appeared on Starhopper’s exterior around August 14th. Those tiles were black (somewhere between matte and glossy), featured indents likely related to manufacturing or mounting, and appeared to be attached to Starhopper by way of a white, marshmallow-esque adhesive. Altogether, each tile bears a striking resemblance to two-thirds of a hexagonal Oreo cookie, arranged in a grid and sort of squished onto Starhopper.
Aside from the seven tiles attached directly to the exterior Starhopper’s liquid methane tank, at least one additional tile was spotted on a small mount structure welded to the bottom of one of the vehicle’s tripod legs. Likely just five or so meters (~15 feet) away from Starhopper’s Raptor engine, that particular tile would have been subjected to intense heating and sound (i.e. thermal and acoustic shock) during the Starship testbed’s final ~60-second flight.

In fact, the Raptor-facing tile may have been put through an even more stressful test than intended, owing to the apparent difficulties Raptor SN06 had during its minute-long performance. Whether the result of shoddy installation and plumbing or an issue with Raptor itself, the engine demonstrated some unusual behavior as it throttled down for Starhopper’s landing, turning its largely transparent exhaust plume into a massive flamethrower.
Raptor or adjacent plumbing also appeared to suffer some kind of leak just before landing, producing significant flames that clearly scorched Starhopper’s rear and destroyed a huge amount of cabling in the area, visible just below the hexagonal tile group. Likely related, several views of the test showed a COPV flying off – clearing having suffered an anomaly that broke it free from Starhopper – around the same time as the vehicle ended its hop with a hard landing.
Tiles on Starhopper?
This does raise the question: why were prototype Starship heat shield tiles attached to Starhopper, a distinctly suborbital prototype that never reached a speed of ~20 m/s (40 mph), let alone orbital velocity? Without actually performing a reentry, what value could be derived? Taken alongside the almost-simultaneous orbital reentry test of four separate Cargo Dragon-shaped tile prototypes, the likely explanation is actually pretty simple and serves as an excellent example of SpaceX’s agile approach to aerospace development.
The three separate tile locations (Starhopper’s tank and leg and Cargo Dragon’s heat shield) all delivered extremely unique test conditions to their respective ceramic tile prototypes. Attached directly to a cryogenic fuel tank, Starhopper’s seven-tile set was almost certainly meant to test methods of mounting a heat shield on a stainless steel tank. Those tiles went through several thermal cycles from propellant loading, spent weeks unprotected in hellish South Texas heat and humidity, and suffered through the shock of flight and a hard landing.
The lone Raptor-adjacent tile was subjected to heating from a live engine just a dozen or so feet away, along with all the brutal acoustic stresses associated with it, perhaps including an unintended fire during anomalous engine performance. Cargo Dragon C108’s four ceramic tiles were far closer to a full-fidelity test, although they were shaped for and attached to the spacecraft in a manner that minimized their one-to-one relevance to Starship’s likely shield design. Regardless of the level of the test’s fidelity, they still managed to survive a true-to-life orbital reentry with nothing more than some soot stains from Dragon’s normal PICA-X shield material.
In short, SpaceX (hopefully successfully) demonstrated a large number of Starship’s ceramic tile design requirements before an actual flight-capable Mk1 or Mk2 Starship is ready for comparable testing. Of course, the most important tests will involve a combination of all Starship-relevant conditions (Raptor engines, cryogenic tank-wall mounting, hexagonal tiles, weeks spent in space, orbital reentry, etc.) for a full-fidelity reentry campaign with an actual Starship prototype. SpaceX CEO Elon Musk says those tests could begin very soon – as early as October 2019 – and the suite of piecemeal Cargo Dragon and Starhopper tests that prototype tiles have already completed will undoubtedly grease the wheels towards that ambitious goal.

Tesla’s $2.9 billion bet: Why Elon Musk is turning to China to build America’s solar future
Tesla looks to bring solar manufacturing to the US, with latest $2.9 billion bet to acquire Chinese solar equipment.
Tesla is reportedly in talks to purchase $2.9 billion worth of solar manufacturing equipment from a group of Chinese suppliers, including Suzhou Maxwell Technologies, which is the world’s largest producer of screen-printing equipment used in solar cell production. According to Reuters sources, the equipment is expected to be delivered before autumn and shipped to Texas, where Tesla plans to anchor its next phase of domestic solar production.
The move is a direct extension of a vision Elon Musk has been building for months. At the World Economic Forum in Davos this past January, Musk announced that both Tesla and SpaceX were independently working to establish 100 gigawatts of annual solar manufacturing capacity inside the United States. Days later, on Tesla’s Q4 2025 earnings call, he made the ambition concrete: “We’re going to work toward getting 100 GW a year of solar cell production, integrating across the entire supply chain from raw materials all the way to finished solar panels.”
Job postings on Tesla’s website reflect that same target, with language explicitly calling for 100 GW of “solar manufacturing from raw materials on American soil before the end of 2028.”

The urgency behind the latest solar manufacturing target is rooted in a set of rapidly emerging pressures related to AI and Tesla’s own energy business. U.S. power consumption hit its second consecutive record high in 2025 and is projected to climb further through 2026 and 2027, driven largely by the explosion in AI data centers and the broader electrification of transportation. Tesla’s own energy division, which produces the Megapack utility-scale battery storage system, has been growing rapidly, and solar supply is a critical companion component for the business to scale. Musk has argued that solar is not just a clean energy option but the only one that makes economic sense at the scale AI infrastructure demands.

Ironically, the path to domestic solar independence currently runs through China. Sort of.
Despite Tesla’s stated push to localize its supply chain, mirrored recently by the company’s plan for a $4.3 billion LFP battery manufacturing partnership with LG Energy Solution in Michigan, Tesla still relies on China-based suppliers to keep its cost structure intact.
The $2.9 billion equipment deal underscores a tension Musk himself acknowledged at Davos: “Unfortunately, in the U.S. the tariff barriers for solar are extremely high and that makes the economics of deploying solar artificially high, because China makes almost all the solar.” Building the factory in America requires buying the machinery from the country Tesla is trying to reduce its dependence on.

The regulatory pathway adds another layer of complexity. Suzhou Maxwell has been seeking export approval from China’s commerce ministry, and it remains unclear how quickly that clearance will come. Still, the market has already reacted, with shares in the Chinese firms reportedly involved in the talks surged more than 7% following the Reuters report that broke the story.
Whether Tesla can hit its 2028 target of 100GW of solar manufacturing remains an open question. Though that scale may seem staggering, especially in such a short timeframe, we know that Musk has a documented history of “always pulling it off” in the face of ambitious deadlines that may slip. But, rest assured – it’ll get done.

Elon Musk reveals date of Tesla Full Self-Driving’s next massive release
Initially planned for a January or February release, v14.3 aims to add some reasoning and logic to the decisions that Full Self-Driving makes, which could improve a lot of things, including Navigation, which is a major complaint of many owners currently.
Tesla CEO Elon Musk revealed the date of Full Self-Driving’s next massive release: v14.3.
For months, Tesla owners with Hardware 4 have been utilizing Full Self-Driving v14.2 and subsequent releases. Currently, the most up-to-date FSD version is v14.2.2.5, which has definitely brought out mixed reviews. With releases, some things get better, and other things might regress slightly.
For the most part, things are better in terms of overall behavior.
However, many owners have been looking forward to the next release, which is v14.3, about which Musk has said many great things. Back in November, Musk said that v14.3 “is where the last big piece of the puzzle lands.”
He added:
“We’re gonna add a lot of reasoning and RL (reinforcement learning). To get to serious scale, Tesla will probably need to build a giant chip fab. To have a few hundred gigawatts of AI chips per year, I don’t see that capability coming online fast enough, so we will probably have to build a fab.”

Tesla Full Self-Driving v14.2 is a considerable improvement from early versions of the suite, but we have written about the somewhat confusing updates that have come with recent versions.

They’ve been incredibly difficult to gauge in terms of progress because some things have gotten better, but there seems to be some real regression on a handful of things, especially with confidence and assertiveness.
Musk confirmed today on X that Tesla is already testing v14.3 internally right now. It will hit a wide release “in a few weeks,” so we should probably expect it by late April.
It’s in testing right now. Wide release in a few weeks.

Overall, there are high hopes that v14.3 could be a true game changer for Tesla Full Self-Driving, as many believe it could be the version that Robotaxis in Austin, Texas, some of which are driverless and unsupervised, are running.
It could also include some major additions, including “Banish,” also referred to as “Reverse Summon,” which would go find a parking spot after dropping occupants off at their destination.
What Tesla will roll out, and when exactly it arrives, all remain to be seen, but fans have been ready for a new version as v14.2.2.5 has definitely run its course. We have had a lot of readers tell us their biggest request is to fix Navigation errors, which seem to be one of the most universal complaints among daily FSD users.
