In 2000, the Shuttle Endeavor carried the Shuttle Radar Topography Mission (SRTM) payload into orbit. Shuttle astronauts used the payload to map in high-detail and three-dimensions more than 70% of the Earth's surface--the most complete and accurate rendering of the planet's land masses ever attempted. The Museum possesses two primary components--the mast canister and the outboard support structure with its antennas--crucial to that mission.
This artifact is a mount used to hold a GPS antenna, which provided data on the exact postion of the outboard support structure during the mission. This was combined with other data to create an accurate map of the Earth's surface.
NASA transferred this artifact to the Museum in 2003.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
