Collection Item Summary:

Launched in 1974, Applications Satellite Technology 6 (ATS 6) was the last of a series of NASA experimental satellites designed to test new communications, meteorological, and other technologies. The spacecraft used three-axis stabilization to maintain a constant orientation toward Earth, especially important for ATS 6's principal mission of communications.

These momentum wheels (two of three on the spacecraft) helped ATS 6 maintain this stabilization.

These artifacts are flight spares, which NASA transferred to the Museum in 1978.
