The International Space Station (ISS) isn’t just an orbiting laboratory, spaceship testing-ground and multinational geek-fest — it’s also the world’s highest (250 miles) and fastest (17,500mph) computer network. Tracking and Data Relay Satellites (TDRS) allow constant radio communications in the S- and Ku-band, while UHF signals are used to talk with the Space Shuttle and crew members on spacewalks. There’s also a single IP phone for cheap interstellar calls and ‘limited’ webcam video-conferencing abilities. There is significantly large network on board the Station, comprising 68 IBM ThinkPad A31 laptops and 32 Lenovo ThinkPad T61p devices. Space Station IT: High technology article tells about the IT technology used on board. Interview: The Space Station’s IT guys interviews Tyson Tucker and Joey Crawford, the NASA flight controllers responsible for maintaining uptime in mankind’s first permanent space colony. I saw those interesting articles first mentioned at Slashdot.
