Skylab was an ambitious space program designed to test all manner of until-that-time unproven thoughts about space -- mainly, could man really live for long periods in orbit?

Here we have gathered up a bunch of Skylab facts from NASA History Office for an overview of the mission that NASA will celebrate this month.
