Star Tracker, Shuttle, Columbia

Display Status:

This object is on display in the Time and Navigation exhibition at the National Air and Space Museum in Washington, DC.

Collection Item Summary:

This device was mounted near the nose of a Shuttle orbiter and was used to establish its position once in orbit. A star tracker acquired a known star through its optics, and provided data on that acquisition to the Shuttle's on-board inertial measurement unit and computer to fix the orbiter's position.

This device flew on the Space Shuttle Columbia for its maiden mission in April 1981 and on 15 subsequent flights.
