Signal from OSCAR 2

OSCAR 2 was an American amateur radio satellite . It was built as the successor to OSCAR 1 .

Structure and Mission

OSCAR 2 largely had the same structure as its predecessor OSACR 1. In contrast to it, the surface was designed differently, as it was found that OSCAR 1 had problems with overheating. Thanks to an optimized arrangement of the strips on the surface, the temperature profile could be kept constant during the service life of the satellite.

The satellite was launched on June 2, 1962 as a secondary payload with a keyhole satellite with a Thor - Agena rocket from Vandenberg Air Force Base . On June 21, 1962 it burned up when it was planned to re- enter the earth's atmosphere.

Its COSPAR designation was first 1962-Chi-2 and was changed to 1962-022B with the conversion in 1963.
