The shuttle is retiring next year and, according to NASA, the remaining five flights may be the most difficult ever flown. That's why they created this contest for the final space shuttle patch.
One of these will be the winner:
Among other activities, they organised the final mission patch contest to make NASA employees more involved and concentrate on the missions ahead. The entries - a total of 85 - were created by all shuttle program members, from technicians to astronauts. Fifteen of these will go into a voting web page, where NASA employees would be able to vote. The favourite - although this could be vetoed by NASA's top brass - will be the final mission patch. My bet is hidden in the gallery, but looking at it, it's clearly perfect NASA patch material.
