ODERACS-D was one of six spheres deployed from the shuttle mission STS-60. The purpose of the Orbital Debris Calibration Spheres experiment was to calibrate the radars and telescopes used for orbital debris measurements by putting objects of the size of interest into orbit for observation. One of the pair was polished, the other diffuse. The 3 pairs were 2, 4, and 6 inches in diameter.
