Lessons Learned – Mars Observer (MO) TWTAs Were Not Qualified (while powered) for Pyrotechnic Shock (1993)
Year: 1996
Abstract: Abstract:
The MO Traveling Wave Tube Amplifiers (TWTAs) were not powered during qualification Pyrotechnic Shock testing. As a result, the TWTA beam and cathode heaters were not powered during the critical MO tank pressurization to allow real time telemetry during this critical event. Fully consider the cost/risk tradeoff of not qualifying critical inherited designs for new operational uses.
