SpaceX’s BFR program pursuing advanced Starship heat shield with NASA help
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.

Tesla ends Full Self-Driving purchase option in the U.S.
In January, Musk announced that Tesla would remove the ability to purchase the suite outright for $8,000. This would give the vehicle Full Self-Driving for its entire lifespan, but Tesla intended to move away from it, for several reasons, one being that a tranche in the CEO’s pay package requires 10 million active subscriptions of FSD.
Tesla has officially ended the option to purchase the Full Self-Driving suite outright, a move that was announced for the United States market in January by CEO Elon Musk.
The driver assistance suite is now exclusively available in the U.S. as a subscription, which is currently priced at $99 per month.
Tesla moved away from the outright purchase option in an effort to move more people to the subscription program, but there are concerns over its current price and the potential for it to rise.

Although Tesla moved back the deadline in other countries, it has now taken effect in the U.S. on Sunday morning. Tesla updated its website to reflect this:

There are still some concerns regarding its price, as $99 per month is not where many consumers are hoping to see the subscription price stay.
Musk has said that as capabilities improve, the price will go up, but it seems unlikely that 10 million drivers will want to pay an extra $100 every month for the capability, even if it is extremely useful.
Instead, many owners and fans of the company are calling for Tesla to offer a different type of pricing platform. This includes a tiered-system that would let owners pick and choose the features they would want for varying prices, or even a daily, weekly, monthly, and annual pricing option, which would incentivize longer-term purchasing.
Although Musk and other Tesla are aware of FSD’s capabilities and state is is worth much more than its current price, there could be some merit in the idea of offering a price for Supervised FSD and another price for Unsupervised FSD when it becomes available.

Musk bankers looking to trim xAI debt after SpaceX merger: report
xAI has built up $18 billion in debt over the past few years, with some of this being attributed to the purchase of social media platform Twitter (now X) and the creation of the AI development company. A new financing deal would help trim some of the financial burden that is currently present ahead of the plan to take SpaceX public sometime this year.
Elon Musk’s bankers are looking to trim the debt that xAI has taken on over the past few years, following the company’s merger with SpaceX, a new report from Bloomberg says.
xAI has built up $18 billion in debt over the past few years, with some of this being attributed to the purchase of social media platform Twitter (now X) and the creation of the AI development company. Bankers are trying to create some kind of financing plan that would trim “some of the heavy interest costs” that come with the debt.
The financing deal would help trim some of the financial burden that is currently present ahead of the plan to take SpaceX public sometime this year. Musk has essentially confirmed that SpaceX would be heading toward an IPO last month.
The report indicates that Morgan Stanley is expected to take the leading role in any financing plan, citing people familiar with the matter. Morgan Stanley, along with Goldman Sachs, Bank of America, and JPMorgan Chase & Co., are all expected to be in the lineup of banks leading SpaceX’s potential IPO.
Since Musk acquired X, he has also had what Bloomberg says is a “mixed track record with debt markets.” Since purchasing X a few years ago with a $12.5 billion financing package, X pays “tens of millions in interest payments every month.”
That debt is held by Bank of America, Barclays, Mitsubishi, UFJ Financial, BNP Paribas SA, Mizuho, and Société Générale SA.
X merged with xAI last March, which brought the valuation to $45 billion, including the debt.
SpaceX announced the merger with xAI earlier this month, a major move in Musk’s plan to alleviate Earth of necessary data centers and replace them with orbital options that will be lower cost:
“In the long term, space-based AI is obviously the only way to scale. To harness even a millionth of our Sun’s energy would require over a million times more energy than our civilization currently uses! The only logical solution, therefore, is to transport these resource-intensive efforts to a location with vast power and space. I mean, space is called “space” for a reason.”
The merger has many advantages, but one of the most crucial is that it positions the now-merged companies to fund broader goals, fueled by revenue from the Starlink expansion, potential IPO, and AI-driven applications that could accelerate the development of lunar bases.

Tesla pushes Full Self-Driving outright purchasing option back in one market
Tesla announced last month that it would eliminate the ability to purchase the Full Self-Driving software outright, instead opting for a subscription-only program, which will require users to pay monthly.
Tesla has pushed the opportunity to purchase the Full Self-Driving suite outright in one market: Australia.
The date remains February 14 in North America, but Tesla has pushed the date back to March 31, 2026, in Australia.

Tesla announced last month that it would eliminate the ability to purchase the Full Self-Driving software outright, instead opting for a subscription-only program, which will require users to pay monthly.
If you have already purchased the suite outright, you will not be required to subscribe once again, but once the outright purchase option is gone, drivers will be required to pay the monthly fee.
The reason for the adjustment is likely due to the short period of time the Full Self-Driving suite has been available in the country. In North America, it has been available for years.
Tesla hits major milestone with Full Self-Driving subscriptions
However, Tesla just launched it just last year in Australia.
Full Self-Driving is currently available in seven countries: the United States, Canada, China, Mexico, Australia, New Zealand, and South Korea.
The company has worked extensively for the past few years to launch the suite in Europe. It has not made it quite yet, but Tesla hopes to get it launched by the end of this year.
In North America, Tesla is only giving customers one more day to buy the suite outright before they will be committed to the subscription-based option for good.
The price is expected to go up as the capabilities improve, but there are no indications as to when Tesla will be doing that, nor what type of offering it plans to roll out for owners.
