Chronology
1 event
1995 October 23
22:03 GMT - . Launch Site: Wallops Island. Launch Complex: Wallops Island LA0A. LV Family: Conestoga. Launch Vehicle: Conestoga 1620. FAILURE: Noise in guidance system led to excessive steering of one of the booster motors and finally depletion of the motor's hydraulic fluid. The vehicle went out of control at T+46 seconds.. Failed Stage: G.- Meteor - .
Nation: USA.
Agency: EER.
Apogee: 10 km (6 mi).
At T+44.4 seconds the vehicle started a turn to the south and pitched down. The ISDS destruct system commanded the destruct packages at T+46.202 seconds. The ISDS failed to operate on two Castor 4 stage 1 motors but operated on the other four. At T+47.67 sec the ISDS destroyed a non-burning Castor 4B motor. The third stage Castor 4B and fourth stage Star 48 were not destroyed and impacted in the ocean. Cause of the failure was identified as the flight control system attempting to respond to noise being received on a data line, resulting in early depletion of hydraulic control steering fluid on stage 1 motor 6.
