Discoverer 7

 1959-010


The Agena engine was successfully shut down by the mechanical integrator for the first time on flight 7 (mission 9004, Agena 1051). The 920 kg flight 7 satellite lost 3-axis stabilization on Agena 1051 due to a power supply failure and subsequent depletion of nitrogen gas prior to orbit 2 and the capsule wasn’t ejected.

Launch time in the commander's report was quoted as 1229 PDT (1929 UT) but I believe this is a typo for PST. An AFBMD report gives the time as 1226 PST.
