Discoverer 24

KH-5 Argon satellite lost to Agena power failure.

Discoverer 24 (Corona 9018A) was a U.S. KH-5 Argon reconnaissance satellite that failed to reach orbit after launch on 8 June 1961. A Thor DM-21 Agena-B rocket lifted off from Vandenberg Air Force Base, but the Agena stage suffered a power supply failure during ascent, leading to loss of telemetry and a ballistic impact in the Pacific Ocean.
