ODERACS-2B (Orb Debris Rad Calib Sph 2B) was one of 6 spheres deployed from the shuttle mission STS-63. 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.

ODERACS 2B was released on February 4, 1995 at 04:57 on the Launch Pad 39B at the Kennedy Space Center, Florida, via the Space Shuttle Discovery, and was launched along with Spartan 204-F1.
