To get the ball rolling, this is me:
I'm not an astronaut, I just play one on the web.
For the curious, this picture was taken at NASA's Goddard Space Center in Greenbelt, Maryland. Goddard has a visitor's center open to the public. It consists of two rooms filled to overflowing with flight components and exhibits about space flight. The larger of the two rooms also has a shuttle simulation module from the standpoint of mission controller. The smaller room has a lot of interactive experiments and a kiosk with all of the cheesy commercials NASA used to run extolling the social benefits of space flight. It's a completely worthwile experience if you are ever in the D.C. area.
Goddard also runs a brief tour of the facilities, but they don't really let you near anything interesting (and my tour guide was a clueless twit which did not help matters at all).
Back to the pictures. You can:
