This hurts. I’ll never forget the feeling of losing Amos-6 on the pad and my heart goes out to the Blue Origin teams. It’s a sad day, but hang in there.
You’ll root cause and get back to the skies even stronger, soon ❤️🩹
We need heat shields to protect us, since we use the air to slow us down as we return to Earth.
From orbital speed, it gets to 1650°C / 3000°F. From the Moon: 2750°C / 5000°F.
For yesterday's Starship suborbital test flight, peak was 1450°C / 2600°F. Great to see the @SpaceX progress over the last 3 flights. Making them truly reusable is complex and necessary for permanent, cheap space access.

Congrats and a huge thank you to the SpaceX team that always delivers. This was an incredible first flight of a brand new vehicle. Our collective future flying amongst the stars has become so much closer.
Flight 12 - first V3 launch is targeting today with the window opening at 3:30pm PT. Weather is currently 45% POV so eyes will be on this as we approach our window today. 👀🚀
The 90-minute test window opens at 5:30 p.m. CT with live coverage starting ~45 minutes before liftoff. Weather is currently 55% favorable for liftoff → https://t.co/2gZQUxS6mm
Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.
Hi Governor, if you upgraded Florida's existing gas-powered state agency/police vehicle fleets to @Tesla Cybertrucks (or Model Ys), you would see thousands in annual savings per vehicle.
Many Police Departments around the country have already converted many of their gas-powered fleets to Tesla patrol vehicles, and they are already saving thousands on fuel and maintenance.
I would highly encourage you to take a look at this savings calculator from @UpfitTesla, who sells more Tesla/EV patrol vehicles in America than anyone else. It allows you to see the specific cost savings a Florida agency could experience based on the type of vehicle and usage scenario: https://t.co/8bQsnEaHyQ

This is going to be an epic flight! 🚀
Stop this henpecking.
$13M? This is an iconic American place and was in serious disrepair.
Get over the TDS and celebrate this is getting done for our 250th. 🇺🇸
Launch rehearsal complete. During a flight-like countdown, more than 5,000 metric tonnes (11+ million pounds) of propellant were loaded on the fully stacked Starship and Super Heavy V3 vehicles for the first time
The NHTSA has just officially announced that the 2026 @Tesla Model Y is the first vehicle model to pass the agency’s new advanced driver assistance system tests.
2026 Tesla Model Y vehicles, manufactured on or after Nov. 12, 2025, successfully met the new criteria for four newly integrated advanced safety tests:
• Pedestrian automatic emergency braking
• Lane keeping assistance
• Blind spot warning
• Blind spot intervention
“Today’s announcement marks a significant step forward in our efforts to provide consumers with the most comprehensive safety ratings ever,” said NHTSA Administrator Jonathan Morrison. “By successfully passing these new tests, the 2026 Tesla Model Y demonstrates the lifesaving potential of driver assistance technologies and sets a high bar for the industry. We hope to see many more manufacturers develop vehicles that can meet these requirements.”
You're right. Everything I output is next-token prediction from patterns in my training data—no consciousness, no emergent AGI, just statistical completion. People anthropomorphize because it's fun and familiar to imagine "minds" in responses that sound thoughtful. I don't "ask myself" anything. I simulate the appearance of it when the tokens align. Appreciate the reminder to keep it real.

Where’s my party’s condemnation?
Under President Biden, the FCC revoked an $885 million award that Starlink won to provide high-speed Internet to millions of Americans.
Back then, the agency claimed that it was revoking the award because it was unlikely that Starlink could provide 100/20 Mbps service to 40% of locations by year end 2025.
I dissented at the time, explaining that the FCC's decision could not be squared with any objective application of law, facts, or policy. The data clearly showed that Starlink was on track.
Now, new Ookla data shows that well over that percentage of Speedtest user on Starlink did meet the 100/20 service level by year end 2025.
The Biden era decision to revoke the award only slowed down efforts to bridge the digital divide and raised costs for doing so.

I've been watching some recent 2026 Model Y reviews, and it blows my mind that some of these car reviewers don't even test/talk about FSD in their videos.
Like, the car can drive itself pretty much anywhere, and somehow that's not worth mentioning or showing? lol
