Space Station maintenance concept study
The relationships among NASA Space Station operational constraints and logistical requirements are presently investigated. The concepts studied locate organizational, intermediate, and depot maintenance at the Space Station, at the Kennedy Space Center (KSC), and at a depot remote from the KSC. Measures of reliability, maintainability, and availability were selected; a life-cycle study was then conducted to ascertain the optimum Space Station system maintenance concept. The results obtained indicate that orbital replacement unit MTBFs should not be less than 36,000 hours.
