Artist-supplied caption:
This patch features a white orbiter outline above a sky blue base reminiscent of the Space Shuttle Program delta patch. At the bottom, the years "1981 - 2010" mark the first and last flight of the Shuttle. Around the edge of the patch the names of each orbiter are listed in order of construction from Enterprise to Endeavour. Inscribed in the orbiter is the astronaut symbol. Scattered throughout the patch are fourteen (14) stars in remembrance of the fourteen (14) astronauts who lost their lives during the Space Shuttle Program. On the right side of the patch are some (not all by any means) of the most recognizable accomplishments of the Shuttle program - the ISS, the TDRSS network, and the Hubble Space Telescope. In the center/left of the patch the Space Shuttle stack is depicted leaving the planet Earth just after Solid Rocket Booster separation, heading into the sunset as the program draws to a close.
If it gets selected, the lettering around the edges should be white and the background black instead of grey. I just colored it grey so the stars and other details would show up, and the lettering was black so I would know where it is.
