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."

Elon, question for you: on the picture below AI sat mini seems to have 3-400kw of solar panels for 100kw of compute. PUE of 1.2, 35% panel decay over the lifetime of the bird barely get me to 200kw. What am I missing?

SpaceX put 10 megawatts of solar power in space across 3000 gen1 Starlink satellites, then they put 100 megawatts in space with 7000 gen2. soon, they're doing 1000 megawatts with gen3. SpaceX is basically 10xing space solar every few years!

有个小插曲，PostgreSQL 本想装在 windows 11 下面的，因为 Mac Air 空间太吃紧，后悔买了 256G 的，直接上 2T 最省事儿 一想，反正是测试，为什么不叫 Codex App 直接帮我装呢，我还不用折腾在 windows 上装 PG 的痛苦 早些年，反复装 Oracle 可太痛苦了，Solaris 还有同学记得吗，那叫一个爽啊。反反复复装 50遍，都算少的 现在可太轻松了，前提是有台 Mac

In South Korea 🇰🇷, the solar panels in the middle of the highway have a bicycle path underneath - cyclists are protected from the sun, isolated from traffic, and the country can produce clean energy.

The first molten salt tower solar thermal power station in China’s Xinjiang is now operational. It generates nearly 200 million kWh of green power a year—enough for 240,000 people’s usage.
