One of the coolest benefits of visiting the Kennedy Space Center in person is the chance to meet a real astronaut, many of whom have retired to the same area where they once worked. At times, you’ll have seen headliners such as Jim Lovell and Story Musgrave making the rounds. Typically, these guys (and a very few women) love basking in fandom and in reliving old tales of glory—and unlike out-to-pasture sportsmen, these old-timers really did risk their lives the way heroes are supposed to—so these small-group sessions are geared toward questions.
