Launching everything from Earth becomes an expensive way to do space. SpaceX's path to petawatt-scale power for AI is mass drivers on the Moon. With 1/6 of Earth’s gravity and no atmosphere, a giant electromagnetic launcher could fling solar-powered AI compute into space using electricity instead of burning rocket...

🚨 CHINA IS RACING TO BUILD A SPACE SOLAR POWER PLANT THAT COULD BEAM ELECTRICITY FROM ORBIT TO EARTH. Scientists at Xidian University have successfully tested a ground-based system that can wirelessly transmit kilowatt-level power over 100 meters using microwaves. Their ultimate goal is far more ambitious: placing large solar power stations in geostationary orbit (36,000 km up), where sunlight is available 24/7 with no weather or atmosphere blocking it. The project, called Zhuri (“chasing the sun”), uses mirrors to concentrate sunlight onto solar panels, converts the electricity into microwaves, and beams it down to a receiving antenna (rectenna) on Earth. Why this matters: • In space, solar energy is up to 6 times more efficient than on Earth because there’s no night, clouds, or atmospheric filtering • A single large space solar station could theoretically generate gigawatts of continuous clean power enough for millions of homes • The team has already proven the system can beam power to multiple moving targets at once • China is now among the world leaders in this technology, alongside the US and Japan The deeper implication: Space-based solar power has been a dream for decades because it could provide truly baseload renewable energy. While the technical and financial challenges are enormous (building massive structures in orbit, precise microwave beaming, and safety), steady progress like this brings the concept closer to reality. If successful, it could fundamentally change how humanity generates and distributes energy moving power collection off the planet entirely. Near-term applications could include wirelessly charging satellites or powering future lunar bases. Do you think space-based solar power will become a major energy source in the coming decades, or will it stay too expensive and complex? Follow for more frontier energy and space technology developments.

NASA has just launched a new website for its Moon Base missions, which aims to build a permanent $20 billion U.S. base on the Moon. SpaceX's Starship rocket will play a big role in these missions. "The Moon Base is a home away from Earth for Artemis astronauts who will live and work at humanity’s first lunar outpost. NASA is leading global teams of innovators across international space agencies, industry, and academia to build the Moon Base and establish an enduring human presence near the lunar South Pole for the benefit of all. Phase One (Now–2029): Experiment and Learn NASA will begin with a rapid series of robotic missions to scout the lunar South Pole region, test technologies, and prepare for surface operations ahead of future astronaut missions.: • A major increase in lunar activity, with up to 25 missions, including 21 landings. • Crewed and autonomous rovers for mobility demonstrations and surface preparation, along with four drones known as MoonFall and communications relay and observation satellites. • Early demonstrations of power, navigation, communications, and nuclear radioisotope heater unit technologies designed to endure the long lunar night. • Scientific payload opportunities integrated across landers and rovers. • The first tangible footprint of Moon Base effort, with four tons of payload delivered to test what works on the lunar surface. Phase Two (2029–2032): Early Habitation By 2029, NASA will transition to assembling semi-permanent infrastructure and initiating early habitation and logistics operations: • Deployment of expanded solar power systems and initial nuclear surface power capabilities, potentially including fission reactors and radioisotope power systems. • Upgraded rovers, potential advanced MoonFall drones, and early habitation elements. • Enhanced surface-to-orbit communications networks to provide reliable connectivity across the lunar South Pole region. • Delivery of up to 60 tons of cargo through as many as 24 landings using low-, medium-, and heavy-class cargo landers. Phase Three (2032 and Beyond): Sustained Human Presence This phase will scale operations to achieve a true enduring presence, with routine crew rotations and continuous surface activity. This is when living and working on the Moon becomes a reality: • Semi-permanent habitation modules with spacious interior for crew living and operations. • Operational fission surface power systems capable of delivering steady, reliable energy through the long lunar nights, leveraging in situ resource manufacturing. • Advanced logistics networks supported by crewed and autonomous rovers to keep the base supplied and functioning year-round. • Delivery of up to 38 tons of cargo annually to sustain habitats, power systems, logistics operations, and major science outposts, enabled by low-cost reusable heavy-lift capabilities."

🚨 NEWS FROM NASA In a bold and decisive move, NASA Administrator Jared Isaacman just announced a $20 billion plan to build America’s permanent base on the Moon — and they’re doing it in just 7 years. Today, NASA officially confirmed it is cancelling plans for the Lunar Gateway — the small space station that was supposed to orbit the Moon as a waypoint for astronauts. Instead, those components and resources will be repurposed directly for the surface base, accelerating humanity’s return to sustained lunar presence. The goal is clear — move beyond short visits and flags-and-footprints missions. NASA wants a real, long-term foothold on the Moon: habitats, power systems, rovers, scientific labs, and infrastructure that can support crews for months at a time. This base will serve as the foundation for deeper space exploration, resource utilization (like mining lunar ice for fuel and water), and eventually — Mars. The $20 billion investment over the next seven years will reshape major parts of the Artemis program. It comes with real urgency too — China is pushing hard toward its own crewed Moon landing by 2030, and the U.S. is determined to lead, not follow. This isn’t just about science. · A permanent lunar base means:Testing technologies for Mars missions in a real off-world environment · Developing in-situ resource utilization (turning Moon dirt into rocket fuel and oxygen) · Opening the door to a true cislunar economy · Inspiring the next generation of engineers, scientists, and explorers Private industry will play a massive role, as always — with contractors already building key hardware now being redirected. This is the kind of ambitious, focused leadership the space program has needed. From the first boots on the Moon in 1969 to building a thriving outpost there by the early 2030s — what an incredible leap forward. Significanly, the Moon isn’t just a destination anymore: it’s becoming home base for humanity’s expansion into the Solar System.

I genuinely think the Terafab is going to end up being one of the biggest moves ever made in human history to secure the future of AI... and I think most people still don’t fully see what Elon is trying to do here. The signs are clear to me. This is Tesla, xAI, and SpaceX essentially hinting to us that they are not going to wait on the world to give them the compute the team needs. They are going to build it themselves at a scale no one has ever attempted. When you really break it down, it gets a bit nutty. This is going to be a fully vertically integrated chip factory that will be producing over 1 terawatt of AI compute per year. This is NEXT LEVEL BIG. Today, AI is limited by chips. You can have the best models, the best engineers, the best everything... but if you don’t have enough compute, you will eventually hit a wall. Elon told us, the world can only supply a tiny fraction of the chips his companies will need. So this is the solution. Terafab puts everything under one roof like design, manufacturing, memory, packaging, testing, which means that they can build chips very fast.. like really fast. I'm talking about 100-200 billion custom AI chips per year at full capacity. Chips designed specifically for: • Tesla cars and Optimus robots • xAI models • Space-based compute You see, while other companies and CEOs are thinking Earth, Elon is planning for AI in space. Around ~80% of the compute is expected to go orbital, powered by solar energy bc Earth simply doesn’t have enough electricity. The U.S. grid is only about ~0.5 terawatts, while space has basically UNLIMITED energy if you can capture it. And this is the steps to get it: Starship launches → space compute → solar-powered AI → feeds back into everything to Earth. Bro... Elon and his companies are playing at a whole different level... And this is why I keep telling people that the Terafab is going to be the secret ingredient that will be the real unlock for everything: • Robotaxis at scale • Billions of Optimus robots • Massive AI models running 24/7 • Future off-world, other planet infrastructure Without these chips, none of this can happen... but with the Terafab, all of this becomes possible. That’s why Elon is calling it “the final missing piece.” I agree.
