September 8-10, 2004
MODULE LEADER: Keith Avery, Mission Research Corporation
MISHAP DATE: November/December 2000.
FAILURE AND MAIN CONTRIBUTING FACTOR
Loss of power to the receivers on two spacecraft.
The STRV 1C and 1D spacecraft were launched on 16 November 2000 as secondary payloads aboard the Arianespace 5 launch vehicle. Approximately two weeks after launch a problem with the 1C spacecraft appeared. Within a couple days, the 1D spacecraft exhibited a similar anomaly. Neither spacecraft would respond to commands from the ground. Telemetry from both spacecraft indicated that power had been cut to the receivers. Subsequent ground investigation confirmed the telemetry message and the root cause of the mishap. We will take a closer look at the cause of the problem, why the problem occurred, and what can be learned from this incident.
