SpaceX has almost finished writing V1.0 of an in-house AI training stack in C that exact-maps to 220k GB300s with 800G NICs, making heavy use of pipeline parallelism and getting as close to bare metal as possible.
The potential speed improvement vs JAX for large training runs is over an order of magnitude.
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."

I just found something interesting hidden on the SpaceX website

It’s a live Dragon docking simulator where you try docking with the ISS yourself
And really… this game is way trickier than it looks
You think it’ll be simple until the capsule starts drifting sideways and rotating at the same time 😭
Made me realize how insanely precise real docking actually is. The controls, timing, movement… everything has to be perfect
Mostly true. What matters is securing the long-term future of consciousness, both on Earth and other heavenly bodies.
We cannot just focus on Earth, because there are irreducible external (eg massive meteor) and internal (eg global nuclear war) cataclysmic risks.
The Moon is faster to make self-growing, but is more susceptible to problems on Earth. Mars will take longer to make self-growing, because it is so hard to reach, but is more secure from Earth disasters for that same reason.
Both the Moon and Mars should have self-growing civilizations. Making this happen is the prime directive of SpaceX.
NASA Administrator Jared Isaacman: "@SpaceX is probably our greatest commercial space company, hands down. We rely on SpaceX heavily to put our astronauts to and from the international space station."
