Who says that astronauts are all work and no play? Luke Skywalker’s actual lightsaber from “Return of the Jedi” was bundled up and taken on the latest trip to the Discovery. Before being packed away in its flight kit and stowed away in an area in the space shuttle, it was personally given a sendoff from George Lucas, Chewbacca, and some Jedi Knights. Ever since Gus Grissom carried a few dimes on his spaceflight in 1961, many items have been taken along for the ride. Although astronauts are not allowed to bring anything personal for profit, sometimes memorabilia will find its way to sites such as CollectSPACE. We prefer to think they they brought the weapon along just in case they need the Force to be with them.
