That’s a real poster from NASA. It’s
not fan made or a spoof. It’s really what NASA had on for that mission
to the International Space Station.
In fact NASA has a whole bunch of
really odd, more than a little cool posters for their various missions;
among the expected inspirational posters are a bunch that touch on
movies and other pop culture things, and they’re all available for free
download over at the NASA site. They
have hi-res versions that can be printed out and even framed, if you so
felt inclined.
