    The Physical Layer: Who Owns the Power, Water and Land Under the AI Boom

    A data center is not a cloud. It is a heat engine, and every site needs three things at once: firm power, somewhere to dump the heat and permitted land with fiber. US on-site data center water use ran to roughly 17.4 billion gallons in 2023, with another 211 billion gallons embedded in the electricity behind it. Nuclear, ocean and orbital compute are the bets placed on what happens when those three stop lining up, and exactly one data-center-class AI chip has operated in orbit so far.

    The Retail Counter Closed

    SpaceX has not announced an end to Falcon 9 rideshare. Its filings show most Falcon launches already serve internal payloads, while government missions, NASA work and Starship’s lunar campaign compete for the same industrial base. The result may not be Falcon retirement after 2028, but a market in which launch slots are scarce and increasingly controlled by integrators that bought capacity early.

    Red Flag in Orbit: What the Space Force’s $981M NITE-STAR Contract Can Buy

    Space Systems Command awarded 15 companies positions on NITE-STAR, a multiple-award vehicle with a $981 million ceiling, then disclosed no task orders, no obligation and no hardware purchase. The ceiling is the largest number in the announcement and the least useful measure of what has been delivered. What the vehicle can eventually buy, from digital ranges to live on-orbit training assets, will be decided by task orders that have not yet been announced.

    Shijian-31 vs. the Mission Robotic Vehicle: Two Ways to Own GEO

    China’s Shijian-31 is sweeping the entire geostationary belt from a 12.5-hour Molniya orbit, shifting its viewing longitude 15.7 degrees each pass and re-scanning the whole belt in roughly 23 days. Five weeks later, Northrop Grumman’s Mission Robotic Vehicle launched carrying DARPA’s RSGS robotic arms on a 10-month electric-propulsion climb to GEO. One power is building the ability to see everything in the belt. The other is building the ability to touch it.

    Golden Dome Funding Faces a $60B Reconciliation Squeeze

    The administration wants $17.12 billion for Golden Dome next year, and about 98 percent of it rides on reconciliation. The House narrowly adopted its budget resolution on 22-JUL-2026, but the $60 billion defense instruction names no programs. Tracking satellites and interceptor prototypes are advancing on separate tracks while Congress decides what to fund.
