Space Cover #173: Shuttle Reaction Control System (RCS) Testing

The Space Cover of the Week commemorates the testing of the space shuttle reaction control system (RCS). These tests took place between January 5-July 3, 1978 at the White Sands Missile Range, New Mexico.

These covers were serviced by Stan Henderson of 3-Muscateers cachets and were autographed by the Chief of the Propulsion Test Office, Mr. Rob Tillett.
