Extensive process clearing MMOD strike on Endeavour window for re-entry
The Mission Management Team (MMT) have initially cleared a Micrometeoroid Orbital Debris (MMOD) strike to Endeavour’s window 6 (Pilot’s window), with full re-entry rationale expected. Meanwhile, Shuttle manager John Shannon praised Kennedy Space Center (KSC) engineers for an “unbelievable” vehicle. Impacts from MMOD are a usual – if not undesirable – event during missions, with…
