Orbit: The path the shuttle travels on as it moves around the Earth. Orbital Plane: The plane in which the orbit lies. Prime Meridian: An imaginary line at longitude 0 degrees that runs through Greenwich, England; the starting point for measuring distances east or west on a map or globe. Slider Map: A large map of the world and a sheet of plastic overlay with an orbit ground track printed on it. The slider map is used in KidSat to select targets. SMOC: Student Mission Operations Center. Target: A location on the Earth that a school chooses to photograph. Targeting: The process of selecting potential photographic sites for KidSat using the slider map, the SMOC Web pages, atlases, etc. UCSD Gateway: Located in San Diego, California, also called the Mission Control Gateway (MCG). During a KidSat shuttle fight, the UCSD gateway receives and processes photo requests from SMOCs and sends them to JSC to be uplinked to the KidSat camera on the shuttle.
