ODERACS 2A

ODERACS-2A (Orbital Debris Radar Calibration Sphere 2A) was one of six spheres deployed from the shuttle mission STS-63. The purpose of the Orbital Debris Radar Calibration Sphere 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 in (51 mm), 4 in (100 mm), and 6 in (150 mm) in diameter.

ODERACS 2A was released on 4 February 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 .
