This summer, the National Aeronautics and Space Administration is celebrating its 50th anniversary. Take this quiz to find find out how NASA knowledgeable you really are.

You consider yourself a staunch supporter of space travel. As a child, you spent many a day lying under your mother's dining room table, pushing imaginary overhead buttons in your very own spaceship. When Apollo 13 opened in movie theaters, you spent all 140 excruciating minutes questioning its historic accuracy while your date slumped over snoozing. You even know that Starfleet Headquarters is located in San Francisco.

But how much do you really know about NASA, the US agency that's been pushing to explore that final frontier for the last fifty years?

It drives me mad when I hear a guy complain that he eats and eats but can’t gain weight, and that he resorts to drinking protein shakes to “bulk up.” [Insert world’s smallest violin playing here.] Excuse me? Did I hear him right?

Argh. But really, Pfizer (and those men) take the cake even when it comes to Lipitor.
