Atthese stations, radar and telemetry equip-ment track the Gemini spacecraft and acquiredata on the performance of its componentsand its occupants. Radio, telephone and tele-typewriters funnel this information to God-dard. High-speed computers at Goddard,each with realtime capability, use the rawdata to make constant flight contingencyrecommendations, predict flight path, and de-termine the time to initiate re-entry—ail ona near-instantaneous and continuous basisthroughout a mission.

Through this system, theheart of the entire network, pass messagesbetween operators around the world. At thetouch of a button, the system reaches in-stantly into overseas support stations suchas Woomera, Australia; the Canary Islands;and Johannesburg, South Africa. The entire network homes-in on a largeSCAMA console at Goddard. The consoleprovides push-button voice contact with asmany as 220 worldwide stations . . everystation needed to handle any contingencycan be instantly called upon. It also allowsfor unlimited conferencing—operators canset up simultaneous conference calls withany or all of the network stations. In addition, television films about the re-cent flight were carried by the TELSTAR®communications satellite to Europe. Thefilms, showing part
