The patch shows physical and mission components of the Space Shuttle Program, in an arc surrounding the crew station. The Ascent shows the SRB's and SSME's propelling the Orbiter and External Tank. Orbital operations are represented by a payload being delivered on-orbit. The Orbiter in gliding flight represents Entry and Landing. A view from inside the Orbiter's cockpit symbolizes the crew and flight support.
