Thiele, Mission Specialist, European Space AgencyDesignated the Shuttle Radar Topography Mission (SRTM), STS-99 completed the most detailed topographical radar mapping of Earth ever attempted. A mast holding the radar mapping equipment was deployed to its full length of about 200 feet shortly after launch, and after a series of tests radar mapping began less than 12 hours into the mission. The crew was split into two teams so that radar mapping could be conducted around the clock. Radar mapping of Earth between 60 degrees north latitude and 56 degrees south latitude was conducted. Data was sent to the Jet Propulsion Laboratory (JPL) for processing and analysis, and even early in the mission useful data was produced.
