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 Optimus dramatically collapses after teleoperator mishap
It seemed blatantly obvious that whoever was controlling the Optimus robot from behind the scenes did not disconnect their ability to manipulate its movements
Tesla Optimus dramatically collapsed after a teleoperator mishap at the company’s “Future of Autonomy Visualized” event in Miami this past weekend.
It seemed blatantly obvious that whoever was controlling the Optimus robot from behind the scenes did not disconnect their ability to manipulate its movements, then left the controls, causing Optimus to collapse.
A video captured at the event shows Optimus doing a movement similar to taking a headset off, likely what the teleoperator uses to hear guest requests and communicate with other staff:

After the headset removal motion was completed, Optimus simply collapsed backward, making for an interesting bit of conversation. While it was a mishap, it was actually pretty funny to watch because of the drama displayed by the robot in the situation.
This was obviously a mistake made by the teleoperator, and does not appear to be a spot where we can put any sort of blame on Optimus. It would have likely just stood there and waited for controls to resume if the teleoperator had disconnected from the robot correctly.
However, details are pretty slim, and Tesla has not announced anything explaining the situation, likely because it seems to be a pretty face-value event.
Tesla Optimus shows off its newest capability as progress accelerates
The Tesla Optimus program has been among the most hyped projects that the company has been working on, as CEO Elon Musk has extremely high hopes for what it could do for people on Earth. He has said on several occasions that Optimus should be the most popular product of all time, considering its capabilities.
Obviously, the project is still a work in progress, and growing pains are going to be part of the development of Optimus.
In its development of Optimus Gen 3, Tesla has been working on refining the forearm, hand, and fingers of Optimus, something that Musk said is extremely difficult. However, it’s a necessary step, especially if its capabilities will not be limited by hardware.
All in all, Optimus has still been a very successful project for Tesla, especially in the early stages. The company has done an excellent job of keeping Optimus busy, as it helps with serving customers at events and the Tesla Diner, and is also performing tasks across the company’s manufacturing plants.
Tesla has finally announced the features for the 2025 Holiday Update, which includes a wide variety of new inclusions that are both functional and just for fun.
The new features are plentiful, but there were a handful of things we were expecting to see based on what we know. We don’t want to sound ungrateful, because there are a lot of great new things on the way with this update.
Here’s what was included:
Grok with Navigation Commands (Beta)
Grok will now have the ability to add and edit navigation destinations, which is a drastic improvement considering Tesla owners had to use their standard voice commands for this in the past.
The utilization of Grok will likely improve the navigation experience by offering some insight into your destination, including reviews and other points of interest nearby.
It will be enabled by using Grok’s “Assistant” personality.
Tesla Photobooth
“Turn your car into a photobooth! Take selfies from inside your Tesla & give yourself a makeover with fun filters, stickers, and emojis. Share with others right from the Tesla app.”
This feature will be available within the Toybox.
Dog Mode Live Activity
When using Dog Mode to keep your four-legged friend comfortable in the car, you’ll now be able to check in on them as it will share periodic snapshots of the cabin, along with live updates on temperature, battery, and climate conditions.
Dashcam Viewer Update
Dashcam clips are awesome, but they’re void of a lot of information, which could be useful in some instances, especially if there is an accident.
Now, there will be additional details included on each Dashcam clip, like speed, steering wheel angle, and Self-Driving state.
Santa Mode
New graphics, trees, and a lock chime are now available.
Light Show Update
A new Light Show, called Jingle Rush, will be available.
Custom Wraps and License Plates in Colorizer
Colorizer will now be known as “Paint Shop” in the Toybox. You will now be able to personalize your Tesla Avatar with window tints, custom wraps, and license plates. Preloaded designs will be available, but owners will be able to use their USB Flash Drives to create one that suits their style.
Navigation Improvements
Changing the order of your destinations will be easier through a new “Favorites” tab, and Home and Work can now be set by dropping a pin.
There will also be “Suggested Destinations,” which will be determined through recent trips and habits while parked.
Supercharger Site Map
Perhaps the most significant feature of the Holiday Update, Tesla is adding a 3D view of select Tesla Superchargers by tapping “View Site Map.”
When navigating to a location with this capability, the site layout, live occupancy, and nearby amenities will be available. Drivers will also be able to choose which stall to Supercharge.
This is only available at a handful of locations currently, but it will expand to more Superchargers as it becomes more robust.
Automatic Carpool Lane Routing
Navigation will include an option to utilize carpool lanes. Your route will automatically choose the carpool lane when eligible.
Phone Left Behind Chime
If the in-car occupant detection system does not see anyone in the car and there is a phone key, or if a phone is left inside the cabin, your Tesla will chime a few seconds after the doors close.
Charge Limit Per Location
You can now save a charge limit for the current location while parked and it will be applied automatically the next time you charge there.
ISS Docking Simulator
In a SpaceX collaboration, Tesla has added this game to its in-car Arcade:
“Become an astronaut and prove your skills by docking with the International Space Station. Control & guide the rocket in this 3D docking simulator game using a set of controls based on actual interfaces used by NASA astronauts.”
Additional Improvements
-
Enable or disable wireless phone charging pads in Controls > Charging (S3XY) or Controls > Outlets & Mods (Cybertruck)
-
Add Spotify tracks to your queue right from the search screen & scroll through large Spotify playlists, albums, podcasts, audiobooks & your library seamlessly, without paging
-
Take the vibes up another level with rainbow colors during Rave Cave. Accent lights color will change along with the beats of your music. App Launcher > Toybox > Light Sync
-
Lock Sound now includes Light Cycle from Tron Mode. Toybox > Boombox > Lock Sound
What’s Missing
There are a handful of features we expected to see with the Holiday Update, but were not included.
Banish Feature
Tesla has been teasing the Banish functionality for quite a few years, but evidently, it is not quite there yet.
Banish will allow owners to get out of their vehicle at the entrance of their destination, and the car will go find a spot and park itself. Some refer to it as “Reverse Summon.”
Apple CarPlay
With all of the rumors regarding Apple CarPlay and then the evidence that Tesla was working to bring CarPlay to vehicles, we really expected it to come with the Holiday Update.
We’re not upset it’s not here, though. Tesla’s in-car UI is significantly better, at least in our opinion.
Parking Spot Selection
One of the biggest gripes about the new Arrival Features with Full Self-Driving v14 is that choosing a set parking spot is not available. This is especially frustrating for Tesla owners who rent or live in townhouse neighborhoods or apartment complexes with assigned parking.
Tesla seems to be working on this based on the release notes for v14.2, where it said future capabilities would include Parking Spot Selection.

Man credits Grok AI with saving his life after ER missed near-ruptured appendix
The AI flagged some of the man’s symptoms and urged him to return to the ER immediately and demand a CT scan.
A 49-year-old man has stated that xAI’s Grok ended up saving his life when the large language model identified a near-ruptured appendix that his first ER visit dismissed as acid reflux.
After being sent home from the ER, the man asked Grok to analyze his symptoms. The AI flagged some of the man’s symptoms and urged him to return immediately and demand a CT scan. The scan confirmed that something far worse than acid reflux was indeed going on.
Grok spotted what a doctor missed
In a post on Reddit, u/Tykjen noted that for 24 hours straight, he had a constant “razor-blade-level” abdominal pain that forced him into a fetal position. He had no fever or visible signs. He went to the ER, where a doctor pressed his soft belly, prescribed acid blockers, and sent him home.
The acid blockers didn’t work, and the man’s pain remained intense. He then decided to open a year-long chat he had with Grok and listed every detail that he was experiencing. The AI responded quickly. “Grok immediately flagged perforated ulcer or atypical appendicitis, told me the exact red-flag pattern I was describing, and basically said “go back right now and ask for a CT,” the man wrote in his post.
He copied Grok’s reasoning, returned to the ER, and insisted on the scan. The CT scan ultimately showed an inflamed appendix on the verge of rupture. Six hours later, the appendix was out. The man said the pain has completely vanished, and he woke up laughing under anesthesia. He was discharged the next day.
How a late-night conversation with Grok got me to demand the CT scan that saved my life from a ruptured appendix (December 2025)
byu/Tykjen ingrok
AI doctors could very well be welcomed
In the replies to his Reddit post, u/Tykjen further explained that he specifically avoided telling doctors that Grok, an AI, suggested he get a CT scan. “I did not tell them on the second visit that Grok recommended the CT scan. I had to lie. I told them my sister who’s a nurse told me to ask for the scan,” the man wrote.
One commenter noted that the use of AI in medicine will likely be welcomed, stating that “If AI could take doctors’ jobs one day, I will be happy. Doctors just don’t care anymore. It’s all a paycheck.” The Redditor replied with, “Sadly yes. That is what it felt like after the first visit. And the following night could have been my last.”
Elon Musk has been very optimistic about the potential of robots like Tesla Optimus in the medical field. Provided that they are able to achieve human-level articulation in their hands, and Tesla is able to bring down their cost through mass manufacturing, the era of AI-powered medical care could very well be closer than expected.
