OSCAR 2 is the second amateur radio satellite launched by Project OSCAR into Low Earth orbit. OSCAR 2 was launched June 2, 1962, by a Thor-DM21 Agena B launcher from Vandenberg Air Force Base, Lompoc, California. The satellite, a rectangular box (30 cm × 25 cm × 12 cm (11.8 in × 9.8 in × 4.7 in)) weighing 10 kg (22 lb), was launched as a secondary payload (ballast) for Corona 43, the fifth launch of a KH-4 satellite.

The satellite employed a monopole transmitting antenna 60 cm (24 in) long extended from the center of the convex surface, but had no attitude control system. OSCAR 2 lasted 18 days, ceasing operation on June 20, 1962, and re-entered June 21, 1962.[1][2]

OSCAR 2 incorporated certain design changes from the earlier OSCAR 1.[2]
