Lessons Learned – Surveyor Rocket Motor Almost Fired (~1965)
Year: 1996
Abstract: Abstract:
To prove that electrical connections were properly made, a test of motor control circuits was included after fueling and pressurization of tanks. Had slightly higher pressure been present in the fuel tanks when the pilot valve for the motor control was activated, rocket firing could have injured observers and destroyed the spacecraft. Functional tests must be carefully screened against a standing policy that at least two protective elements are included to prevent irreversible action.
