Building Star Trek

The 50th anniversary of "Star Trek" is celebrated. Included: the effort to restore the original 11-foot, 250-pound model of the USS Enterprise; and an effort to build a model of the ship's bridge. Also: technological concepts the series introduced, such as hand-held communication devices, desktop computers and space shuttles; and the work to create real-life versions of other things conceived on the show, including warp drive, medical tricorders, cloaking devices and tractor beams.
