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.

GM CEO Mary Barra says she told Biden to give Tesla and Musk EV credit
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
General Motors CEO Mary Barra said in a new interview on Wednesday that she told President Joe Biden to credit Tesla and its CEO, Elon Musk, for the widespread electric vehicle transition.
She said she told Biden this after the former President credited her and GM for leading EV efforts in the United States.
During an interview at the New York Times Dealbook Summit with Andrew Ross Sorkin, Barra said she told Biden that crediting her was essentially a mistake, and that Musk and Tesla should have been explicitly mentioned (via Business Insider):
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
GM CEO Mary Barra said to Andrew Sorkin at the New York Times Dealbook Summit that she pulled President Biden aside and said Tesla CEO @elonmusk deserved the credit for EVs:

Back in 2021, President Biden visited GM’s “Factory Zero” plant in Detroit, which was the centerpiece of the company’s massive transition to EVs. The former President went on to discuss the EV industry, and claimed that GM and Barra were the true leaders who caused the change:
“In the auto industry, Detroit is leading the world in electric vehicles. You know how critical it is? Mary, I remember talking to you way back in January about the need for America to lead in electric vehicles. I can remember your dramatic announcement that by 2035, GM would be 100% electric. You changed the whole story, Mary. You did, Mary. You electrified the entire automotive industry. I’m serious. You led, and it matters.”
People were baffled by the President’s decision to highlight GM and Barra, and not Tesla and Musk, who truly started the transition to EVs. GM, Ford, and many other companies only followed in the footsteps of Tesla after it started to take market share from them.

Musk would eventually go on to talk about Biden’s words later on:
“They have so much power over the White House that they can exclude Tesla from an EV Summit. And, in case the first thing, in case that wasn’t enough, then you have President Biden with Mary Barra at a subsequent event, congratulating Mary for having led the EV revolution.”
In Q4 2021, which was shortly after Biden’s comments, Tesla delivered 300,000 EVs. GM delivered just 26.

Tesla Full Self-Driving shows confident navigation in heavy snow
So far, from what we’ve seen, snow has not been a huge issue for the most recent Full Self-Driving release. It seems to be acting confidently and handling even snow-covered roads with relative ease.
Tesla Full Self-Driving is getting its first taste of Winter weather for late 2025, as snow is starting to fall all across the United States.
The suite has been vastly improved after Tesla released v14 to many owners with capable hardware, and driving performance, along with overall behavior, has really been something to admire. This is by far the best version of FSD Tesla has ever released, and although there are a handful of regressions with each subsequent release, they are usually cleared up within a week or two.
Tesla is releasing a modified version of FSD v14 for Hardware 3 owners: here’s when
However, adverse weather conditions are something that Tesla will have to confront, as heavy rain, snow, and other interesting situations are bound to occur. In order for the vehicles to be fully autonomous, they will have to go through these scenarios safely and accurately.
One big issue I’ve had, especially in heavy rain, is that the camera vision might be obstructed, which will display messages that certain features’ performance might be degraded.

I found the steepest, unplowed hill in my area and tested the following:
• FSD 14.2.1 on summer tires
• FSD 14.2.1 on winter tires
• Manual drivingBut I think the most impressive part was how FSD went DOWN the hill. FSD in the snow is sublime $TSLA pic.twitter.com/YMcN7Br3PU

Well.. I couldn’t let the boys have all the fun!
Threw the GoPro up and decided to FSD v14.2.1 in the snow. Roads were not compacted like the other day, a little slippery, but overall doable at lower speeds. Enjoy the video and holiday music 🎶

Moving into the winter months, it will be very interesting to see how FSD handles even more concerning conditions, especially with black ice, freezing rain and snow mix, and other things that happen during colder conditions.
We are excited to test it ourselves, but I am waiting for heavy snowfall to make it to Pennsylvania so I can truly push it to the limit.

Tesla hosts Rome Mayor for first Italian FSD Supervised road demo
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets.
Tesla definitely seems to be actively engaging European officials on FSD’s capabilities, with the company hosting Rome Mayor Roberto Gualtieri and Mobility Assessor Eugenio Patanè for a hands-on road demonstration.
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets. This comes amid Tesla’s push for FSD’s EU regulatory approvals in the coming year.
Rome officials experience FSD Supervised
Tesla conducted the demo using a Model 3 equipped with Full Self-Driving (Supervised), tackling typical Roman traffic including complex intersections, roundabouts, pedestrian crossings and mixed users like cars, bikes and scooters.
The system showcased AI-based assisted driving, prioritizing safety while maintaining flow. FSD also handled overtakes and lane decisions, though with constant driver supervision.
Investor Andrea Stroppa detailed the event on X, noting the system’s potential to reduce severe collision risks by up to seven times compared to traditional driving, based on Tesla’s data from billions of global fleet miles. The session highlighted FSD’s role as an assistance tool in its Supervised form, not a replacement, with the driver fully responsible at all times.
Path to European rollout
Tesla has logged over 1 million kilometers of testing across 17 European countries, including Italy, to refine FSD for local conditions. The fact that Rome officials personally tested FSD Supervised bodes well for the program’s approval, as it suggests that key individuals are closely watching Tesla’s efforts and innovations.
Assessor Patanè also highlighted the administration’s interest in technologies that boost road safety and urban travel quality, viewing them as aids for both private and public transport while respecting rules.
Replies on X urged involving Italy’s Transport Ministry to speed approvals, with one user noting, “Great idea to involve the mayor! It would be necessary to involve components of the Ministry of Transport and the government as soon as possible: it’s they who can accelerate the approval of FSD in Italy.”
