Smithsonian's Air & Space Magazine posted their picks for the 50 most memorable images from NASA's half-century history. Of course, this list will ignite debate like rocket fuel on a campfire, but I got a special kick out of the image above. From the Air & Space caption:
Shuttle Enterprise with cast of Star Trek, 1976 NASA's prototype space shuttle was to have been named Constitution, but fans of the Star Trek TV show mounted a write-in campaign that led to it being named Enterprise. Here the show's cast (minus William Shatner) poses with the test craft.
