ODERACS (Orbital Debris Radar Calibration Sphere) were a set of passive rada calibration objects of differnet size.

ODERACS A to F was a set 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 three pairs were 2, 4, and 6 inches in diameter.

ODERACS 2A to 2F was a set of three spheres 2, 4, and 6 inches in diameter and three dipoles 2, 4, and 6 inches in length.
