This engine ground cover was temporarily installed as a protective barrier on the third of the four right facing RCS (Reaction Control System) thrusters positioned at the aft right of the Space Shuttle orbiter. The cover was used to protect the hypergolic engine from contamination. As its inscription instructs, the cover was removed prior to flight.
