MSL Mobility Assembly Lift Mishap

JPL flight hardware was damaged during a lift operation preceding a test of the MSL rover Mobility Assembly due to an undetected mechanical interference that was signaled by an anomalous load cell reading. The load cell reading expected during the lift should be documented and communicated in pre-lift briefings, and the readings should be monitored continuously during the lift. Cognizant engineers responsible for flight hardware lifts should receive intensive training in lift operations.
