SpaceX CEO Elon Musk hints that Starship’s ‘sweating’ metal heat shield is no more
In the latest entry of SpaceX’s ever-changing Starship design process, CEO Elon Musk has indicated that the nominally reusable orbital spacecraft has moved away from a liquid-cooled steel heat shield to something slightly more traditional.
This information came as a SpaceX engineer announced during Cargo Dragon’s CRS-18 webcast that the twice-flown spacecraft would mark the first orbital test of a ceramic heat shield tile meant for use on Starship’s windward side. This major design change comes as a significant surprise and seems likely to either delay Starship’s orbital debut or hinder its ultimate reusability, although Musk just as recently claimed that the spacecraft could reach orbit for the first time less than six months from now.
Testing a possible Starship windward side ceramic tile. Maximizing emissivity is best for conductive/particle heating. Nice thing about steel is that tiles can be very thin, unlike carbon fiber or aluminum airframe.— ln(e) (@elonmusk) July 25, 2019
Thin tiles on windward side of ship & nothing on leeward or anywhere on booster looks like lightest option— ln(e) (@elonmusk) July 25, 2019
Back in late-2018 and early-2019, Musk took to Twitter to announce that SpaceX was pursuing an exotic metallic heat shield that would be cooled in large part by flowing liquid methane through tiny holes on its exterior, effectively ‘sweating’ away energy and preventing steel tiles from melting.
Despite incontrovertible evidence that SpaceX performed some amount of significant testing on the hexagonally-tiled steel heat shield concept, Musk’s July 24th tweets indicate that the liquid-cooled heat shield is unlikely to ever be used on Starship. For unknown reasons, SpaceX is instead pursuing some sort of thin ceramic heat shielding to protect the entirety of Starship’s windward side (i.e. the side facing the atmosphere during reentry). A handful of the first flight-qualified ceramic tiles – shaped for Dragon instead of Starship – will be tested on Cargo Dragon during the spacecraft’s orbital mission and eventual reentry.
Of note, this is not the only major design change Starship has undergone in just the last few months. Speaking on May 30th, Elon Musk stated that the design of Starship’s landing legs/fins and actuating wings and flaps has changed significantly since SpaceX revealed the new tripod fins + canard wings configuration in September 2018. According to Musk, that change will (or at least should) not significantly impact Starship’s schedule.
In fact, per his July 2019 claims that the first full-fidelity Starship prototype(s) could begin test flights in September/October and reach orbit as early as December/January, the Starship/Super Heavy schedule has actually radically sped up in the first half of 2019. In December 2018, Musk stated that he believed Starship had a 60% chance of reaching orbit in 2020, let alone late-2019.
For Starship, the massive spacecraft’s heat shield is arguably its single most important component. A failure to ensure that the heat shield is unprecedentedly reusable and reliable – even in the face of ultra-high-velocity interplanetary reentries – will severely limit Starship’s ability to achieve its ultimate goals of enabling affordable access to space and building a sustainable city on Mars. Musk’s comment that ceramic tiles are just “a possible” Starship heat shield element further indicates that SpaceX has yet to firmly settle on a heat shield design, let alone qualify said shield for orbital flight or kick off the mass-production necessary to completely cover multiple Starship halves.
Admittedly, there is still some good news in this unfortunate development. Most notably, the fact that Starship will still be made of steel means that the non-metallic heat shield tiles can be extremely thin and light, as they can be more or less directly attached to Starship’s steel hull. Additionally, steel Super Heavy boosters may be able to get away with zero heat shielding thanks to the relatively high melting point and heat resistance of certain varieties of stainless steel.
So long as both of those characteristics remain true, it’s likely that it will still make sense for Starship/Super Heavy to be built entirely out of steel instead of something like aluminum or carbon composite. With any luck, Elon Musk will provide a detailed update on the status of SpaceX’s next-generation launch vehicle soon after Starhopper survives its first untethered flight test.

The Cybercab is Tesla’s dedicated robotaxi, a gold-finished, two-passenger vehicle without a steering wheel or pedals, designed from the outset for unsupervised autonomous operation. It has been in limited Robotaxi service in Austin since September 2026, operating alongside Tesla’s larger fleet of Model Y vehicles.
Production takes place at Gigafactory Texas, which launched earlier this year. Tesla has stated for some time that it planned to put Cybercabs on sale by the end of the year, and it looks like they will come through on that promise if everything goes according to plan.
The Autonomy Subscription is mandatory for the vehicle to operate because it is void of a steering wheel and pedals. Tesla notes that the subscription and regular vehicle maintenance are required, indicating that personal owners will depend on the company’s software and service infrastructure rather than traditional ownership models.
One month of the subscription is included with purchase and subsequent months are billed separately until canceled.
This limited personal-sales opening marks a shift from Tesla’s earlier emphasis on fleet and transport-as-a-service operations. During the Q3 2026 Earnings Call, executives indicated that the vast majority of Cybercabs would remain Tesla-owned and used for rideshare service, while still aiming to place some vehicles with customers by year-end.
Elon Musk has previously targeted a price below $30,000, which was a huge point of emphasis for the Cybercab being the central point of Tesla’s “transportation-as-a-service” model.
Availability remains restricted to invited customers rather than a public order page, and the initial deliveries are expected only in the Austin area where unsupervised Robotaxi operations are already active. Buyers will need to accept the geographic and operational constraints of current autonomous deployment, as the vehicle cannot be driven manually outside supported zones.
The move gives a small number of early buyers the chance to own Tesla’s dedicated autonomous vehicle at the long-discussed sub-$30,000 price point, while the bulk of production continues to support the company’s expanding Robotaxi network.
UPDATE: The FAA has granted the license for Starship Flight 15.

SpaceX is set to attempt its 15th test flight of Starship this evening from Starbase, Texas.
SpaceX is targeting Starship Flight 15 for a launch as soon as today, Friday, November 13, pending an FAA Flight License, during a 75-minute window that opens at 4:45 p.m. CT (5:45 p.m. ET) from Orbital Launch Pad 2 at Starbase, Texas. The flight remains pending final regulatory approval.

The mission, using Booster 22 and Ship 42, aims to achieve the first full recovery of an orbital launch system. Primary objectives include a tower catch of the Super Heavy booster roughly six and a half minutes after liftoff and the first-ever tower catch of a Starship upper stage after more than 22 hours in space.
SpaceX will perform Starship double catch attempt with Flight 15
Between those catches, Ship 42 is planned to enter a low Earth orbit of about 275 km, complete roughly 14 orbits, and deploy 26 next-generation Starlink V3 satellites (Starlink Group 31-2). Three of those satellites carry cameras to inspect the ship’s heat shield in orbit and help controllers decide whether the vehicle is healthy enough for a return to the tower.
Contingency ocean splashdown options exist if either stage is not cleared for catch.
To watch the attempt, check the link to the broadcast in both X posts in this article. The live webcast is scheduled to begin about 30 minutes before liftoff and is planned to continue through the ship catch the next day, with the possibility of extended onboard views during the orbital coast via Starlink.
Because the schedule is dynamic, check back here or on our social media channels for the latest updates on window timing and regulatory status. A successful dual catch would mark a major milestone toward making Starship a rapidly reusable rocket capable of frequent flights.

Tesla has trimmed its Model Y offerings as its Standard All-Wheel-Drive configuration has been removed from the online configurator after roughly nine months on sale. The move follows the removal of the Cybertruck, as its trims have also been minimized as that vehicle heads for total discontinuation at the end of Summer 2027.
Launched in February 2026 as a mid-tier dual-motor option between the Rear-Wheel-Drive model and the Premium trims, the Standard All-Wheel-Drive Model Y offered 294 miles of range and a 4.6-second 0-60 mph time in a stripped-down package.
🚨 Tesla has pulled the $41,990 Model Y AWD from its U.S. configurator after nine months on sale.
The cheapest AWD Model Y you can order is now the $49,990 Premium AWD, with Premium deliveries quoted for Jan–Mar 2027.
The $39,990 RWD stays, and AWD units remain in inventory. https://t.co/uROJp2lVpx

With it gone, the cheapest new AWD Model Y buyers can configure is now the Premium AWD at $49,990, with estimated deliveries pushed into January–March 2027. The $39,990 rear-wheel-drive Model Y remains available for custom orders, and some AWD units are still listed in inventory.
The move arrives days after Tesla sharply narrowed its Cybertruck lineup. New orders for the Dual Motor AWD and Premium AWD versions have been disabled, leaving only the high-performance Cyberbeast—priced around $109,990 before fees—as the sole configurable option.
Elon Musk has stated that Cybertruck production at Gigafactory Texas will wind down around the middle to late summer of 2027 to free manufacturing space for greater Cybercab output. Tesla has raised prices on remaining trims and is prioritizing higher-margin builds while working through an existing order backlog that exceeds what the line can complete before conversion.
These parallel decisions reflect a broader effort to simplify Tesla’s retail customer lineup. Lower-volume or lower-margin variants are being phased out or deprioritized in favor of core, higher-spec models that generate stronger profitability and clearer production planning.
For the Model Y, this concentrates volume on the remaining RWD and Premium configurations while Premium deliveries already stretch into 2027. For the Cybertruck, it accelerates the transition away from a stainless-steel pickup that underperformed relative to initial volume expectations.
Tesla Model Y Standard Full Review: Is it worth the lower price?
The freed capacity and reduced complexity directly support Cybercab scaling. Tesla began pilot Cybercab production at Giga Texas in early 2026, launched paid autonomous rides in Austin in September, and is preparing for substantial volume growth.
By streamlining the existing vehicle portfolio, the company is reallocating factory space, engineering attention, and supply-chain resources toward its purpose-built Robotaxi, which lacks a steering wheel or pedals and is designed exclusively for unsupervised autonomy.
The result is a leaner retail lineup today and a clearer path to high-volume Cybercab deployment tomorrow.
