SpaceX installs orbital Starship heat shield prototype with robots
SpaceX has begun large-scale Starship heat shield installation tests with the help of robots delivered last month in a sign that the company has already begun preparing for the rocket’s first orbital flight test campaign.
Designed to eventually replace SpaceX’s workhorse Falcon 9 and Falcon Heavy launch vehicles, Starship is a fully-reusable two-stage rocket powered by methane and oxygen-fueled Raptor engines. Just like Falcon 9, Starship’s first stage (known as Super Heavy) will launch the combined spacecraft and upper stage to an altitude of 70 to 100 km (40-65 mi) and velocity of ~2.5 to 3 kilometers per second (1.5-1.9 mi/s). Super Heavy will separate, boost back towards land, and either land back at the launch pad or on a floating platform.
SpaceX already has extensive experience launching, landing, and reusing orbital-class rocket boosters thanks to Falcon 9 and Heavy, which have completed 57 landings and been reused 39 times in less than five years. The Starship upper stage, however, will have to survive orbital-velocity atmospheric reentries some 3 to 5 times faster and exponentially more energetic than Super Heavy boosters. To do so routinely while keeping Starship cost and complexity low and reusability high, SpaceX will have to develop an unprecedentedly effective heat shield that is easier to install, maintain, and reuse than anything that has come before it.
As with all SpaceX programs, the company began Starship heat shield installation development as soon as possible, installing a handful of tiles (presumably early-stage prototypes) on Starhopper as far back as H1 2019. This continued with small hexagonal tile installation tests on Starships SN1, SN3, SN4, SN5, and SN6 throughout 2020. While those coupon tests obviously didn’t involve orbital-class reentry heating or buffeting, they were still useful to characterize the mechanical behavior of heat shield tiles under the stress of cryogenic propellant loading, Raptor static fires, and hop tests.
In 2019, SpaceX even tested a few ceramic Starship heat shield tiles on an orbital Cargo Dragon mission for NASA. The fact that no more orbital Cargo or Crew Dragon tests were acknowledged seems to suggest that the demonstration was a success, proving that the tiles can stand up to the stresses of reentry from low Earth orbit (LEO).
Behind the scenes, SpaceX is assuredly performing extensive laboratory-style tests with tiles and an agreement signed with NASA Ames Research Center confirmed that the company is using the facility’s arcjet to physically simulate the conditions of orbital-velocity reentry. Tests on the scale of a full Starship, however, are an entirely different story.
The first signs of large-scale heat shield installation testing appeared on July 9th when local resident and photographer Andrew Goetsch (Nomadd) captured photos of a test coupon covering half of an entire steel Starship ring. In April 2020, CEO Elon Musk confirmed on Twitter that the current design involved affixed heat shield tiles directly to Starship’s steel hull with steel studs. It’s unclear how exactly the company is installing steel studs directly onto the ~4mm (0.15 in) thick skins of a pressure vessel or if an off -the-shelf solution was available but Nomadd’s July 9th photos explicitly show the process required to refine the settings on the mystery stud installer.
One month after Nomadd’s spotting, three weeks after a robot delivery, and five days after one of those robots – labeled “HEAT SHIELD – was spotted in action, the first large-scale heat shield installation test article was spotted inside one of SpaceX’s several production tents. The team involved clearly had some fun with the process, installing the tiles in the form of a SpaceX “X”.
In retrospect, robots could be a perfect solution for the affordable, high-volume installation of the thousands of heat shield tiles a single Starship will need. Once tolerances are high enough, it’s conceivable that multiple different Starship sections could be individually outfitted with studs and heat shield tiles by robot, inspected by humans, and joined together to form a complete Starship. Humans would likely need to manually install a gap of tiles around the weld lines of those final sections, but the manual installation work would be reduced to a minimum while keeping the required infrastructure dead simple.
Ultimately, a great deal of work remains before SpaceX can even begin to feasibly attempt orbital Starship test flights, but it’s hard not to get excited by the fact that some of that preparatory work has already visibly begun in South Texas.

Tesla launched unsupervised Robotaxi service in San Antonio, Texas, on November 9, 2026, with the first rides beginning at 5 a.m. local time.
The company’s official Robotaxi account on X posted the announcement just after midnight, sharing a map that outlines a large operational zone covering much of the city. The geofence is roughly 274 to 275 square miles, making it Tesla’s largest day-one Robotaxi service area to date.

The zone centers on downtown, covers nearly everything inside Loop 410, and extends north to Loop 1604 between Interstate 10 and U.S. 281, with further reach west past State Highway 151, east beyond I-35, and south toward I-37. This area encompasses about one million residents and hundreds of thousands of jobs.
San Antonio International Airport lies inside the geofence, though Tesla is not currently offering airport pickups or drop-offs. This hopefully will happen soon, as ride-sharing to and from the airport can be expensive.
The launch makes San Antonio Tesla’s eighth unsupervised Robotaxi city and its fifth in Texas, joining Austin, Houston, Dallas, and Fort Worth. Florida markets in Miami, Orlando, and Tampa are also live.
🚨 Here’s every active geofence, by size (not including the Bay Area geofence):
• Austin: 435 sq mi (first ride Jun 22, 2025) · Cybercabs live, expanded today • San Antonio: ~275 sq mi (first ride Nov 9, 2026) • Houston: 254 sq mi (Apr 18, 2026) • Fort Worth: 143 sq mi (Nov 2, 2026) • Dallas: 81 sq mi (Apr 18, 2026) • Miami: 31 sq mi (Jul 3, 2026) • Orlando: 26 sq mi (Jul 21, 2026) • Tampa: 24 sq mi (Jul 21, 2026)

Service uses modified Model Y vehicles operating without a safety driver in the vehicle, consistent with recent unsupervised expansions. Cybercab two-seaters remain limited primarily to Austin for now. It’s worth noting that Dept. of Transportation officials in Texas have already ok’d the Cybercab’s operation in Austin, and one official called it “a tangible example of how quickly our transportation system is evolving.”
San Antonio was previously listed among near-term targets in Tesla’s October 2026 Robotaxi safety materials, alongside Las Vegas, Phoenix, and Jacksonville. The rapid Texas rollout follows Fort Worth’s unsupervised debut on November 2 and builds on Austin’s original launch in June 2025.
The 274-square-mile debut remains substantially larger than Waymo’s local footprint and marks continued progress in Tesla’s unsupervised autonomy efforts after starting the year with no such rides. The company has stated ambitions for broader 24/7 operations by the end of 2026 as vehicle counts and software reliability improve.
Tesla has started to perform earthworks engineering on the roughly 3,000-acre site in Fort Bend County, Texas, advancing the massive $10 billion Project Crystal Sun plan to build a vertically integrated solar manufacturing complex.
Flyover drone footage from S.E. Robinson, Jr. released this morning shows the location under development. Tesla has crews on site performing large clearings, but you can also see equipment staging areas, the use of an existing homestead, and active leveling across a substantial portion of the property.
Tesla has started construction on Project Crystal Sun, its $10B vertically integrated solar factory near Houston, Texas.
The plant will make everything from silicon ingots and wafers to finished cells and panels, with operations targeted for Q1 2029.

Public filings first submitted in July under Texas’s Jobs, Energy, Technology and Innovation Act describe a plant that would manufacture the full solar chain: everything from silicon ingots, wafers, coated cells, and finished modules.
Tesla projects 9,712 permanent jobs by 2033, ramping from roughly 1,900 positions in the first year of operations, plus a peak of about 1,147 construction jobs. Construction is targeted for 2026–2028, with commercial production beginning in the first quarter of 2029. An accompanying economic analysis estimates the project could add roughly $107 billion to Texas GDP over several decades.
Local incentives have cleared major hurdles. Lamar Consolidated Independent School District unanimously approved school-tax limitations in September, and Fort Bend County commissioners approved a package of abatements and related agreements in late October that could extend equipment tax breaks for as long as 35 years.
Tesla had previously indicated it was evaluating a competing out-of-state location.
The effort fits broader statements by Musk that Tesla and SpaceX are each working toward 100 gigawatts of annual U.S. solar manufacturing capacity. If built as described, Project Crystal Sun would stand as one of the largest domestic attempts to create a fully integrated solar supply chain on American soil.
While Tesla has not issued a formal groundbreaking announcement, the visible site preparation and high-profile social media activity represent a concrete step forward for a project that has moved from confidential filings to active earthworks in a matter of months.
Elon Musk continues to shed more reasons that justify the cancelation of the Tesla Cybertruck, but some of the reasons for the sunset, as well as the process the company is choosing, do not make a lot of sense.
Musk announced last week on X that Tesla would wind down Cybertruck production in mid-2027, a decision that aims to prioritize Cybercab and its importance to the company’s future and passenger transportation as a whole.
But some of what Tesla and Musk are saying does not seem to make much sense. From the process the company is taking with orders to some of the reasoning for the cancelation, the whole situation seems strange.
With that being said: I totally see the merit in prioritizing Cybercab, but I also believe there is room for Cybertruck, a vehicle that has traditionally had low volumes, especially now at its current price point. If it were not for the cancelation, Cybertruck would sell very few units with the recent price adjustments.
Musk Talks Order Rate vs. Production Rate
The first thing that does not make a lot of sense here is the fact that this morning, Musk said that “The Cybertruck order rate far exceeds our production rate. We will try to make as any as possible before shutting down the line in about 8 months, but will have to return deposits for a lot of people.”
The Cybertruck order rate far exceeds our production rate. We will try to make as many as possible before shutting down the line in about 8 months, but will have to return deposits for a lot of people.
This is not a case of Cybertruck being unprofitable, as has been misreported by legacy media, but rather that the opportunity cost of the complexity of Cybertruck is vastly outweighed by the value of incremental Cybercab production.

Then why is Tesla STILL accepting orders for the Cybertruck if it already cannot fulfill its order log by mid-2027?
There are so many people ordering Cybertruck that will not receive it. If Tesla already is having trouble seeing how it will build its current orders, why would it allow additional ones?
There are going to be a lot of people who are very upset next June or July, all because they placed an order for a truck that Tesla knew it would not have the time to build. At this point, it seems like a better idea from a customer service standpoint to simply stop accepting orders on a certain date, build those trucks, fulfill those orders, and then close production.
Continuing to accept orders at this point seems wildly strange. If anything, it feels like the $59k Cybertruck orderers will be the ones who get the short end of the stick here, but that’s speculation and just a hunch on my end.
If not Cybertruck, then what?
With only the Model 3 and Model Y available for consumers, meaning the general public, to buy, there is now no utility vehicle in the Tesla lineup, and that is definitely a disappointment.
Ford already washed its hands of the Lightning, which means the Rivian R1T will likely be the best-selling EV pickup on the market, dueling with the GMC Hummer Pickup, Chevy Silverado EV, and the GMC Sierra EV. There are several pickups that are set to hit the market soon, like the Slate EV Truck, and Ford’s new EV pickup, the Fathom.
Tesla could provide some some transparency on what it is planning to do with a future pickup or utility design. Musk said in the past that something much cooler than a minivan will be built. Cries for a full-size SUV have been heard by Tesla, but the company seems to adamant on prioritizing ridesharing vehicles instead of vehicles people want for work, climate, or hobbies.
Some clarity here, past the point of “Tesla is still going to build cars” would be nice. Even a simple, “Yes” response from all the people asking if Tesla will build something larger would be more than enough. We don’t need all the details now, but something would be nice.
Closing Thoughts
More than anything, it is important to note that I do believe Tesla is making a tough decision and one that, from a business standpoint, does make sense. However, I also believe that there is room for the Cybertruck in Tesla’s lineup.
One thing I think it’s worth mentioning is Tesla is not that much different from many companies. They do things that are better for the business that will surely upset consumers. The difference is very few companies have a following like Tesla, so when these things happen, they feel very personal.
Add in the fact that Cybertruck has truly become a symbol of Tesla, and people are even more upset about it.
It will all get figured out, but it’s still very confusing when we step back and take a look at the bigger picture.
