SpaceX CEO Elon Musk teases white-hot Starship heat shield testing in video

SpaceX CEO Elon Musk has shared a video showing what looks to be the early stages of testing for Starship’s (BFS) unprecedented metallic heat shield, recently described as a double-layered steel sandwich that will be regeneratively cooled by cryogenic liquid methane.

The glowing metal coupon pictured in Musk’s video appears to be heated by the same high-temperature torches SpaceX (and contractors) use to spin-form Falcon 9 and Heavy propellant tank domes and Merlin 1D and MVac engines, potentially explaining the reported 1100C (2000F) the metallic (steel, presumably) heat shield was being heated to. Compared to the temperature range (~1200-1500C) Starship is expected to experience during reentries, 1100C should – according to Musk – be low enough that “no heat shield [is] needed”. If the coupon pictured is an actual double-layered, regen-cooled test article for Starship’s active heat shield, it will need to be torture-tested to 1500C (and likely beyond) to really prove its worth and reliability.

This is more likely an example of rough, ad-hoc testing being used to generally characterize and navigate the early stages of new technology development, hence the improvised testbed of a few ceramic insulation blankets and industrial torches already on-hand at SpaceX’s Hawthorne, CA factory. A hypersonic wind tunnel or arc jet setup is preferable if the goal is to prove out a truly cutting-edge heat shield, but facilities that feature those testbeds are extraordinarily rare, have niche use-cases, and are not cheap to build or operate.

SpaceX’s metallurgy team and thermal protection engineers will thus probably end up at such a facility (likely NASA Ames) to extensively test Starship’s regeneratively-cooled steel heat shield, with tests like those shown off by Musk acting to guide early development up to the point that accurately simulating reentry conditions is necessary or valuable.

In the meantime, SpaceX suffered a bit of a setback when those responsible for properly securing the first Starship prototype’s nose section failed to account for the threat of even mild winds in South Texas. As a consequence, a minor windstorm – with gusts no more than 50-60 mph (80-90 km/h) – toppled the extremely large and light nose section, causing it to crumple on the ground and nearly fold in half under its own weight. Much like the Falcon fairings SpaceX is already familiar with, the Starhopper’s nose/fairing was clearly optimized for very specific loads and did not appear to be a particularly sturdy structure as SpaceX technicians gradually stacked and welded its thin sheet metal sections together through December and January.

Elon Musk indicated that the injured nose cone would take several weeks to repair, likely pushing the beginning of Starhopper’s hop test campaign into late-February or March.

Tesla CEO Elon Musk has stated that production of Optimus 3 could begin this summer. Musk shared the update in his interview at the Abundance Summit.

According to Musk, Tesla is in the final stages of completing Optimus 3, which he described as one of the world’s most advanced humanoid robots.

“We’re in the final stages of completion of Optimus 3, which is really going to be by far the most advanced robot in the world. Nothing’s even close. In fact, I haven’t even seen demos of robots that are as good as Optimus 3,” Musk said.

He also set expectations on the pace of Optimus 3’s production ramp, stating that the initial volumes of the humanoid robot will likely be very low. Musk did, however, also state that high production rates for Optimus 3 should be possible in 2027.

“I think we’ll start production on Optimus 3 this summer, but very slow at first, like sort of this classic S-curve ramp of manufacturing units versus time. And then, probably reach high volume production around summer next year,” he said.

Interestingly enough, the CEO hinted that Tesla is looking to iterate on the robot quickly, potentially releasing a new Optimus design every year.

“We’ll have Optimus 4 design complete next year. We’ll try to release a new robot design every year,” Musk stated.

Tesla has already outlined broader plans for scaling Optimus production beyond its first manufacturing line. Musk previously stated that Optimus 4 will be built at Gigafactory Texas at significantly higher production volumes.

Initial production lines for the robot are expected to be located at Tesla’s Fremont Factory, where the company plans to establish a line capable of producing up to 1 million robots per year.

A larger production ramp is expected to occur at Gigafactory Texas, where Musk has previously suggested could eventually support production of up to 10 million robots per year.

“We’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk said previously.

The comments suggest that while Optimus 3 will likely begin production at Fremont, Tesla’s larger-scale manufacturing push could arrive with Optimus 4 at Gigafactory Texas.

Tesla showcased its Optimus humanoid robot at the 2026 Appliance & Electronics World Expo (AWE 2026) in Shanghai. The event opened Thursday and featured several Tesla products, including the company’s humanoid robot and the Cybertruck.

The display was reported by CNEV Post, citing information from local media outlet Cailian and on-site staff at the exhibition.

Tesla’s humanoid robot was presented as part of the company’s exhibit at the Shanghai electronics show. On-site staff reportedly stated that mass production of the robot could begin by the end of 2026.

Tesla previously indicated that it plans to manufacture its humanoid robots at scale once production begins, with its initial production line in the Fremont Factory reaching up to 1 million units annually. An Optimus production line at Gigafactory Texas is expected to produce 10 million units per year.

Tesla China previously shared a teaser image on Weibo showing a pair of highly detailed robotic hands believed to belong to Optimus. The image suggests a design with finger proportions and structures that closely resemble those of a human hand.

Robotic hands are widely considered one of the most difficult engineering challenges in humanoid robotics. For a system like Optimus to perform complex real-world tasks, from factory work to household activities, the robot would require highly advanced dexterity.

Elon Musk has previously stated that Optimus has the capability to eventually become the first real-world example of a Von Neumann machine, a self-replicating system capable of building copies of itself, even on other planets. “Optimus will be the first Von Neumann machine, capable of building civilization by itself on any viable planet,” Musk wrote in a post on X.

Tesla is reportedly designing its Cybercab production line to manufacture hundreds of the autonomous vehicles each week once mass production begins. The effort is underway at Gigafactory Texas in Austin as the company prepares to start building the Robotaxi at scale.

The details were reported by The Wall Street Journal, citing people reportedly familiar with the matter.

According to the report, Tesla has been adding staff and installing new equipment at its Austin factory as it prepares to begin Cybercab production. 

People reportedly familiar with Tesla’s plans stated that the company has been growing its staff and bringing in new equipment to start the mass production of the Cybercab this April.

The Cybercab is Tesla’s upcoming fully autonomous two-seat vehicle designed without a steering wheel or pedals. The vehicle is intended to operate primarily as part of Tesla’s planned Robotaxi ride-hailing network. 

“There’s no fallback mechanism here. Like this car either drives itself or it does not drive,” Musk stated during Tesla’s previous earnings call.

Tesla has indicated that Cybercab production could begin as soon as April, though Elon Musk has noted that early production will likely be slow before ramping over time. Musk has stated that the Cybercab’s slow ramp is due in no small part to the fact that it is a completely new vehicle platform

Tesla’s Cybercab is designed to work with the company’s Full Self-Driving (FSD) system and support its planned autonomous ride-hailing service. The company has suggested that the vehicle could cost under $30,000, making it one of Tesla’s most affordable models if produced at scale. Musk has confirmed in a previous X post that the vehicle will indeed be offered to regular consumers at a price below $30,000.

Musk has previously stated that Tesla could eventually produce millions of Cybercabs annually if demand and production capacity scale as planned.
