Hacking the Systems Behind the New Space Race
The deep-tech, hands-on side of today's space race. As SpaceX, NASA, China, and a wave of newcomers fill orbit with satellites, every spacecraft is a flying computer reachable over radio — and a target. Learn the real architecture (orbits, link budgets, the four segments), then break it: replay the Viasat wiper, spoof GPS, hijack a telecommand link, decode raw CCSDS telemetry, poison a ground-station supply chain, and inject on a MIL-STD-1553 spacecraft bus — finishing with counterspace warfare and how the constellation era gets secured.
