SpaceX’s orbital Starship prototype sheds tiles, comes to life during first tests
After weeks of mostly invisible – albeit slow and steady – work at Starbase’s suborbital launch and test facilities, SpaceX has finally kicked off the first orbital Starship prototype’s first test campaign.
Almost two months ago, Starship 20 (S20) departed the factory it was built in for the first time and was rolled a few miles down a South Texas highway to Starbase’s nascent orbital launch site. There, SpaceX briefly installed Ship 20 on top of Super Heavy Booster 4 (B4) – an important first and one done with the same ship and booster pair CEO Elon Musk says could eventually support the rocket’s inaugural orbital launch attempt. Mere hours after that August 6th photo opportunity and fit test, Ship 20 was rolled back to the Starbase build site for another week of work before again returning to the launch site.
This time around, Starship S20 headed for one of two suborbital launch and test stands and ultimately spent the better part of the next six weeks sitting in place as workers swarmed around the 50m (~165 ft) tall spacecraft and upper stage to prepare it for the next steps. In theory, those steps were simple enough, beginning with the completion of two basic qualification tests – the same tests that a half-dozen prototypes preceding Ship 20 completed without issue.
Effectively SpaceX’s first Starship or Super Heavy test of any kind in more than two months, it thankfully didn’t take long for things to get interesting. Before the pad had even been cleared of the last few remaining workers, Starship S20 violently shed a good dozen or so fragile heat shield tiles. CEO Elon Musk quickly confirmed speculation that Starship S20 had effectively jetted the tiles off its nose during a brief test of high-pressure cold gas maneuvering thrusters, coincidentally around the same time as SpaceX began to pressurize the rocket for its first tests.
Going into what was believed to be Starship S20’s first ambient-temperature pressure test and cryogenic proof test, the loss of some heat shield tiles was almost universally expected. In a structure as large as Starship, even just the thermal contraction of steel at supercool temperatures (and expansion as it warms back up) could change the rocket’s diameter an inch or so, potentially causing tiles to scrape or press against each other. About the size of a dinner plate and the thickness of an average paperback book, Starship’s ceramic heat shield tiles have proven to be very fragile, with dozens routinely chipping, cracking, and shattering during and after installation on Ship 20.
One unique (and no less unproven) aspect of Starship is SpaceX’s decision to mount its heat shield directly to the thin steel propellant tanks and skin that make up the rocket’s entire airframe. SpaceX’s first stab at the problem involves studs/pins welded – by robot – directly to the exterior of Starship’s tanks and skin. By embedding small metal plates inside each cast tile, they can be easily installed by aligning the tile and pressing it against each set of three barb-like pins, which then irreversibly lock in place. Over most of Starship’s hull, SpaceX then tacks on blankets of off-the-shelf ceramic wool insulation before tiles are installed on top of that steel and blanket sandwich. Compared to the Space Shuttle and Russia’s Buran, the only other orbital spacecraft to fly with non-ablative heat shields, Starship’s thermal protection system (TPS) is incredibly simple. Of course, the challenges imposed on heat shields by mechanical stresses during launch/landing, orbital reentry, and a need for rapid reusability are anything but simple.
As such, to see tiles blown off Starship S20 by cold gas maneuvering thrusters that were simply placed too close to adjacent TPS was an unexpected route to an expected outcome. During Monday’s nine-hour test window, SpaceX appeared to partially or fully pressurize Starship S20 at ambient temperatures before aborting a cryogenic proof test either before or just after it began. While an ambient-temperature proof was the easier of the two tests on the docket, it’s still encouraging to see no obvious tile loss caused by the actual mechanical stresses involved in the test.
Most importantly, compared to losing dozens of tiles to regular mechanical or thermal stresses, fixing an issue with thruster impingement is much easier and should only require a few design tweaks to one specific Starship component. The real nail-biting moments will come during Starship S20’s seemingly imminent cryogenic proof and static fire debuts, major TPS issues during either of which could necessitate vehicle-wide design changes and cause delays.
With any luck, whatever forced SpaceX to abort Starship S20’s first cryogenic proof test can be easily rectified, opening the door for additional attempts. Two more test windows are scheduled later this week from 5pm to 11pm CDT on Tuesday and Wednesday. Rewatch today’s brief testing below.

Tesla Model Y L has two distinct features for luxurious comfort
This is not to say the other interior additions are not factors in the Model Y becoming a more luxurious and premium vehicle, but the two mentioned in this article are particularly pertinent in that conversation.
Tesla’s new Model Y L has two distinct features that are geared toward giving occupants a taste of luxury with guaranteed comfort.
These two features should definitely be part of the company’s future lineup, and they could prove to be massive upgrades to the Model Y’s interior, which is certainly premium but is missing some things that truly tailor to a “luxury” feel of an automobile.
This is not to say the other interior additions are not factors in the Model Y becoming a more luxurious and premium vehicle, but the two mentioned in this article are particularly pertinent in that conversation.
Tesla Model Y L might not come to the U.S., and it’s a missed opportunity
Power-Adjustable Thigh Supports
In the front seats of the Model Y L, there are power-adjustable thigh supports that will enable some additional comfort on the legs:

Most might think that these thigh supports are simply a feature that makes the ride more comfortable, which is true. However, they have benefits for the ride and after you exit the car.
Providing proper lift on the legs and thighs can be beneficial for people with back problems or posture issues. The lower back takes an increased amount of stress during long car rides, especially as the legs are fixed in the chosen seating position.
Tesla Model Y L officially launched: price, features, and more
Adding some support to the thighs can help reduce pressure on the lower back and hips, and distribute weight more evenly, taking stress off pressure points.
It can also contribute to better spinal alignment. They also have safety benefits, as some riders could have an improved seatbelt position thanks to the thighs being in this position.
Second-Row Mechanical Armrest
Tesla also added mechanical, one-touch armrests to the Model Y L’s second row, a nice and premium touch for the riders in the middle of the vehicle:

Add the additional space the Model Y L provides to riders, and it already gets more comfortable. However, the addition of the mechanical armrests gives a good option of comfort for those who are seated in the second row.
They can also be retracted with the touch of a button, allowing for those in the third row to exit the vehicle easily.
One con to the mechanical portion of these armrests is that it is another moving part, and, of course, that puts it at risk of having issues.
However, it is certainly more premium than a manual armrest, and the flashy carbuyers will appreciate this small but mighty addition.

Tesla’s NHTSA probe is already on its way to being resolved
The problem the NHTSA had with Tesla’s reporting is already on its way to being resolved, as the agency and the company have been in communication.
Tesla is being probed by the National Highway Traffic Safety Administration (NHTSA) for not reporting accidents in a timely manner, the agency said on Thursday.
It is already well on its way to being resolved, the agency said.
The agency’s Office of Defects Investigation (ODI) identified numerous instances in which Tesla reported crashes that “occurred several months or more before the dates of the reports.”
The Standing General Order in place by the agency requires crash reports to be submitted within five days of Tesla receiving the notice of an accident.
The investigation states Tesla submitted crashes in one of two ways:
“Many of the reports were submitted as part of a single batch, while others were submitted on a rolling basis.”
The problem the NHTSA had with Tesla’s reporting is already on its way to being resolved, as the agency and the company have been in communication.
Tesla has already been in contact with the agency’s ODI and stated that the timing of the reports was an issue with its data collection. The issue has been resolved, Tesla told them.
The NHTSA said the initiation of the probe against Tesla is a “standard process for reviewing compliance with legal requirements, to evaluate the cause of potential delays in reporting, the scope of any such delays, and the mitigations that Tesla has developed to address them.”
It is the latest NHTSA probe into Tesla, as it has also been investigating the company for accidents during Full Self-Driving operation in reduced visibility conditions.
The agency also sought information on the rollout of Robotaxi a few months ago, and how Tesla planned to handle low-visibility conditions in its driverless ride-hailing service.
The NHTSA was interested in knowing how Tesla planned to assess the ability of FSD’s engineering controls, whether any other similar FSD crashes had occurred in low visibility, and if modifications to FSD software would impact its performance in these conditions.

Tesla rolls out minor but significant improvement to Robotaxi service
As per Tesla, Robotaxis will now arrive at their pickup locations with their doors locked.
Tesla has rolled out a minor but significant improvement to its Robotaxi service. The update was shared by the Tesla community on social media platforms such as X.
New Robotaxi App update
As observed by the electric vehicle community on social media, Tesla has started rolling out the Robotaxi App’s Version 25.8.5 (6074) to users. The update seems to be quite minor, though Tesla mentioned something quite notable the update’s “What to Test” section.
As per Tesla, Robotaxis will now arrive at their pickup locations with their doors locked. Customers would not need to unlock the Robotaxis manually, however, as the vehicles would automatically unlock as they approach the car. “You ride now arrives locked and will automatically unlock as you walk up. Just ensure your app has Bluetooth access enabled,” Tesla wrote.
While this update is minor, it does improve the safety of the vehicles themselves. It also provides another layer of convenience for users of the driverless ride-hailing service. The fact that Tesla is already refining the Robotaxi App’s features this early bodes well for the program. It suggests, if any, that the service will already be fairly refined when it starts being opened to more users.
Robotaxi praised for its safety
Tesla is following a deliberate and cautious rollout strategy for its Robotaxi rollout, though early reviews of the system have been quite positive. Some reviewers have also dubbed Tesla’s Robotaxi service as a safer alternative to more conventional ride-hailing services such as Uber.
This was highlighted by auto reviewer Scotty Reiss in a post on A Girl’s Guide to Cars.
“I like the personal safety factor. No driver to threaten or harass you. You control the locking and unlocking of the car. You can change the pickup location at any time. The car will wait for you. You can call the support desk if you need help. You can change your destination if the drop-off area seems sketchy. All of it together makes me feel safer getting a car home from the airport at midnight or into the city after dark, and I definitely feel safer having my daughters take a self-driving rideshare when they go out to meet friends for dinner,” Reiss wrote in her post.
