Description of Driving Event:
The orbital maneuvering system engine trickle purge system is used to prevent oxidation/corrosion damage to the OMS engine injector ball joints. A 1.0 - 1.5 SCFM GN2 flow is applied during postlanding ground operations. Undetected loss of GN2 purge to OMS engine injector cavities could eventually corrode the vehicle system.
