According to a Space Act Agreement signed by SpaceX and NASA’s Ames Research Center in June 2018, the private company has begun working with NASA to acquire some basic experience and lessons-learned with a thermal protection (heat shield) material that is largely new to SpaceX.

Known as TUFROC (short for Toughened Uni-piece Fibrous Reinforced Oxidation-Resistant Composite), the NASA Ames-developed material is capable of withstanding temperatures as high as 1700 C (~3100 F) and is apparently an item of interest to SpaceX’s next-gen BFR (Starship/Super Heavy) rocket program, particularly Starship’s heat shield.

As far as the public is aware, SpaceX has never attempted to manufacture or utilize a heat shield technology like TUFROC. Falling under a domain of thermal protection materials known as ceramic matrix composites (CMCs), TUFROC is essentially an umbrella term that covers any thermal protection system that combines a carbon cap, silica base, and a cured glass coating to prevent oxidation. In recent years, Boeing’s secretive X-37B spaceplane has successfully demonstrated TUFROC reuse after orbital velocity reentries, confirming that the material is capable of surviving those conditions while experiencing minimal to no ablation.

Much like SpaceX borrowed the NASA-developed PICA (phenolic-impregnated carbon ablator) heat shield technology and dramatically improved it for cost-effective use on Cargo (and soon Crew) Dragon, the basic concept behind TUFROC’s heat shielding capabilities likely lends itself just as well to potential improvements in cost reduction, ease of manufacturing, mechanical strength, thermal protection characteristics, and more.

Unlike the fatally fragile carbon-carbon tiles used on the Space Shuttle, TUFROC’s namesake “Fibrous Reinforced” aspects also make it dramatically more resistant to impact related forces like those that led to the Columbia disaster, while still preserving the composite’s impressive heat resistance. NASA already categorizes TUFROC as a “low-cost” TPS, further indicating that SpaceX could quite easily cut the cost of production by a significant degree.

 

What is not clear about this budding relationship is how exactly SpaceX foresees TUFROC or a custom heat shield derivative fitting into its BFR program. Currently, the TPS has only been demonstrated on X-37B as a literal edge-case, standing in for a more traditional silica tile on the leading edges of the small spacecraft’s wings, where reentry heating is often the most extreme. It’s possible that SpaceX is interested in TUFROC for the same reasons – using it to cover BFS/Starship’s forward and rear fins and nothing more.

However, it could be the case that SpaceX hopes an improved TUFROC-X might be viable as a monolithic one-size-fits-all heat shield material throughout BFR’s Super Heavy booster and Starship upper stage. Being forced to deal with a variety of different TPS materials inevitably raises the complexity and cost of a given spacecraft, so being able to significantly reduce the number of materials needed could be a boon for Starship.

Elon Musk

Tesla Board Chair discusses what is being done to protect CEO Elon Musk

Tesla Board Chair Robyn Denholm met with Bloomberg this morning to discuss a variety of topics, but perhaps one of the most interesting was her comments on what is being done to protect company CEO Elon Musk.

After the assassination of right-wing political commentator Charlie Kirk this week, there have been concerns about Musk’s safety, as well as that of other high-profile business leaders and political figures.

Earlier this week, Musk said himself that his security detail would be increased significantly following Kirk’s death, a move that many investors and fans of the company had requested because of political violence.

Elon Musk assures Tesla investors he will enhance his security detail

“Definitely need to enhance security,” Musk said. Tesla spent $3.3 million on Musk’s security in 2024 and January and February 2025. For reference, Meta spent over $27 million on Mark Zuckerberg’s security last year, which is higher than any other tech CEO.

During Denholm’s appearance on Bloomberg TV earlier today, she stated that the company has been focused on Musk’s security detail for “many years,” especially considering he is one of the richest people on Earth and holds an incredible amount of influence.

“It is something that we take very seriously; he takes it very seriously as well. So, again, from a board perspective, it is something we’ve discussed at length,” Denholm said.

Denholm added that she believes “there is not anyone in a boardroom that is not touched by what has happened with Charlie Kirk.”

Although Musk’s political involvement has toned down significantly in the past, he still has enemies, especially based on groups that oppose him and the company specifically. Based on this week’s events, it feels that increased security is a necessary expense Tesla must account for.

Tesla bear turns bullish for two reasons as stock continues boost

“I think from a trading perspective, it looks very interesting,” Nathan said, citing numerous signs of strength, such as holding its 200-day moving average and holding against its resistance level.

A Tesla bear is changing his tune, turning bullish for two reasons as the company’s stock has continued to get a boost over the past month.

Dan Nathan, a notorious skeptic of Tesla shares, said he is changing his tune, at least in the short term, on the company’s stock because of “technicals and sentiment,” believing the company is on track for a strong Q3, but also an investment story that will slowly veer away from its automotive business.

“I think from a trading perspective, it looks very interesting,” Nathan said, citing numerous signs of strength, such as holding its 200-day moving average and holding against its resistance level.

He also said he believes a rally for the stock could continue as it heads into the end of the quarter, especially as the $7,500 electric vehicle tax credit is coming to an end at the end of the month.

With that being said, he believes the consensus for Q3 deliveries is “probably low,” as he believes Wall Street is likely underestimating what Tesla will bring to the table on October 1 or 2 when it reports numbers for the quarter.

Tesla shares are already up over five percent today, with gains exceeding nine percent over the past five trading days, and more than fourteen percent in the past month.

While some analysts are looking at the performance of other Mag 7 stocks, movement on rates from the Federal Reserve, and other broader market factors as reasoning for Tesla’s strong performance, it appears some movement could be related to the company’s recent developments instead.

Over the past week, Tesla has made some strides in its Robotaxi program, including a new license to test the platform in the State of Nevada, which we reported on.

Additionally, the company is riding the tails of the end of the EV tax credit, as inventory, both new and used, is running extremely low, generally speaking. Many markets do not have any vehicles to purchase as of right now, making delivery by September 30 extremely difficult.

However, there has been some adjustments to the guidelines by the IRS, which can be read here:

Tesla lands regulatory green light for Robotaxi testing in new state

This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.

Tesla has landed a regulatory green light to test its Robotaxi platform in a new state, less than three months after the ride-hailing service launched in Texas.

Tesla first launched its driverless Robotaxi suite in Austin, Texas, back on June 22. Initially offering rides to a small group of people, Tesla kept things limited, but this was not to be the mentality for very long.

It continued to expand the rider population, the service area, and the vehicle fleet in Austin.

The company also launched rides in the Bay Area, but it does use a person in the driver’s seat to maintain safety. In Austin, the “Safety Monitor” is present in the passenger’s seat during local rides, and in the driver’s seat for routes that involve highway driving.

Tesla is currently testing the Robotaxi platform in other states. We reported that it was testing in Tempe, Arizona, as validation vehicles are traveling around the city in preparation for Robotaxi.

Tesla looks to make a big splash with Robotaxi in a new market

Tesla is also hoping to launch in Florida and New York, as job postings have shown the company’s intention to operate there.

However, it appears it will launch in Nevada before those states, as the company submitted its application to obtain a Testing Registry certification on September 3. It was processed by the state’s Department of Motor Vehicles Office of Business Licensing on September 10.

It will then need to self-certify for operations, essentially meaning they will need to comply with various state requirements.

This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.

CEO Elon Musk has stated that he believes Robotaxi will be available to at least half of the U.S. population by the end of the year. Geographically, Tesla will need to make incredible strides over the final four months of the year to achieve this.
