First view of the 100kw AI Mini Sat with solar panels and heat radiator to scale. “And that’s just the Mini version. We expect future versions to go to the megawatt range.” — Elon The key missing ingredient is a terawatt of AI compute. Fully integrated fab with recursive improvement locally. Will explore non-traditional computing. Austin, TX. Optimus robots: 1-10 billion units/year. D3 chip optimized for space, designed to run hotter to minimize radiator mass. It will be the vast majority of the compute 100-200GW/yr on Earth. +1TW/yr in space because of power constraints on Earth.

@cb_doge Been saying this for a while…. Let me note, if you can do 1000TW/yr with Lunar mass drivers, Climate Change/Energy Transition is a lesser included scenario. Today our entire civilization only requires 18TW (thermal) and only 55TW (thermal) in 2100.

ELON MUSK: "Space solar actually costs less than terrestrial solar because you don't need heavy glass or framing to protect it from extreme weather events. So as soon as the cost to orbit drops to a low number, it immediately makes extremely compelling sense to put AI in space. It becomes a no brainer. Basically, more of a as you go to space, you get increased economies of scale, and things get easier over time, whereas as you try to put more and more power on the ground, you run out of space and you start using up the easy spots, and then you get next level. Nobody wants the thing in their backyard. So then increasing power on earth has becomes harder over time and more expensive over time, but in space it becomes actually cheaper and easier over time."

just learned that a mentor, Dennis Bushnell, the longest serving Chief Scientist at NASA (Chief for 28 years) died. in his remembrance I wanna share one of his only public presentations, which might be the greatest NASA slide decks of all time (circa 2001) alachuacounty.us/Depts/epd/EPAC…

Our team has been developing the key technologies for this approach for years, including capture mechanisms to constrain and move small asteroids and orbital debris. Accessing materials already in space could eventually enable a new generation of industries beyond Earth. If you're interested in the future of space resources, the articles are worth a read.

This was a GREAT panel talk on beating China to the Moon vs. beating China on the Moon. A topic put forward by Bhavya Lal. Moderated by Jeff Foust with Lori Garver, Thomas Zurbuchen, yours truly, and Pete Garretson.

A Message From Nick Pope: A while ago, following some digestive issues, I was diagnosed with esophageal cancer. Unfortunately, it's Stage 4 and has metastasized to my liver. While I know that it's kindness and hope that leads people to suggest healers and supposed miracle cures, and to say things like "fight it", and "you can beat it", I'm afraid my diagnosis and my situation leaves no doubt whatsoever: I can't beat it. What an amazing adventure I've had! A 21-year career at the UK Ministry of Defence, where I got involved in subjects ranging from financial policy to counter-terrorism; from military policing to UAP. And I saved six cows; it's a long story! The things I've done; the places I've been; the people I've met; and the secrets I've been privy to. I wouldn't have swapped it for the world. And then a second career, where my previous government UAP role brought me to the attention of the world's media, leading me to become a regular commentator on TV news shows and documentaries, as well as consulting and acting as spokesperson on various UFO and alien-themed movies, TV series and video games. The media called me the real Fox Mulder! The true highlight, of course, is life with my wonderful, beautiful and incredibly smart wife, Elizabeth. She's a real-life Agent Scully: a scientist, a skeptic and a redhead. We met randomly in the lobby bar of the Fairmont Hotel in downtown San José (she was an anthropology professor at San José State University) in October 2010 and got married 3 months later. We applied successfully for my Green Card and she had me shipped over and imported to the U.S., where a new adventure began, as Elizabeth and I enjoyed wildlife watching at our wonderful home in Tucson, desert hikes, film noir, true crime, country music, Sunday lunches with my in-laws, and much more besides. Recently, we had an amazing one-year adventure in New York City, living 5 minutes from Times Square, and having a wonderful view of the Empire State Building from our apartment window. We proofread each other's books and articles (I love commas, hyphens and exclamation points way more than Elizabeth, and managed to win at least a few of those battles), and I'm  supporting her in her ongoing fight for free speech, academic freedom, and keeping political correctness, superstition and identity politics out of science and academia. The White House Press Secretary Tweeted one of her recent newspaper articles, which shows the huge impact she's having. I kept working for as long as I could (right up until last week), with my various film/TV interviews, conference appearances, and live events, including my position as moderator of Ancient Aliens Live - where I think I did 94 shows. Sadly, the time has come where I've had to step away from this work. A lot of people have followed my work on UAP. I'm loath to use the word "fans", because I'm not a celebrity. But I am a public figure, and many people have followed me on my journey as I've sought to keep the UAP subject in the public eye, and to frame it as a defense, national security and safety of flight issue - as well as a fascinating science problem. Some of this work has been public knowledge, but some such work, of necessity, has been done behind the scenes. I hope I've helped move the needle forward. But most people, of course, know me through my media interviews and live events. To everyone who's followed me on my journey, thank you - and good luck with your own journeys. I wish you every success and happiness. It's all been amazing, and I'm grateful for the things I've done, not mournful for the things that I won't now get to do. Per Aspera Ad Astra! Nick Pope, Tucson, Arizona, February 12, 2026

Elon Musk@elonmusk·
For those unaware, SpaceX has already shifted focus to building a self-growing city on the Moon, as we can potentially achieve that in less than 10 years, whereas Mars would take 20+ years. The mission of SpaceX remains the same: extend consciousness and life as we know it to the stars. It is only possible to travel to Mars when the planets align every 26 months (six month trip time), whereas we can launch to the Moon every 10 days (2 day trip time). This means we can iterate much faster to complete a Moon city than a Mars city. That said, SpaceX will also strive to build a Mars city and begin doing so in about 5 to 7 years, but the overriding priority is securing the future of civilization and the Moon is faster.

Space will exceed Earth’s entire global economy within this century. Maybe just 50 years.
Elon Musk@elonmusk

@PeterDiamandis Space-based industries will vastly exceed the value of all of Earth, given that you could harness roughly 100,000 times more energy than Earth and still be using less than a millionth of the Sun’s energy!
