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.
These artifacts were spare parts for use in the target light tsicks. These sticks were positioned on the outboard support structure (OSS) during the mission and allowed engineers to determine the orientation of the OSS to the main antenna, located in the Shuttle payload bay.
NASA transferred these artifacts to the Museum in 2003.
