Transit O-24

 1985-066A


The first SOOS (Stacked Oscars On Scout) launch, in Aug 1985, placed two RCA Operational Transit satellites in polar orbit. The first of the pair was Oscar 24 (NNS 30240, O-24). It was placed on standby until 1987.

Two rapidly decaying objects with low ejection velocities, 66D and 66E may be launch adapters. Two slowly decaying objects with high ejection velocities, 66F and 66G, are probably despin weights. The fact that there are only two suggests the stack was despun before spacecraft separation. Alternatively, all four objects may be despin weights (ejected in different directions).

The lower spacecraft is topped by a cradle which carries the load of the upper spacecraft. This cradle remains attached to the lower spacecraft in orbit.
