HOUSTON, TEXAS: 10-year-old Sebastian Sena of Las Cruces, New Mexico checks out the Skylab trainer at Space Center Houston, the visitors’ center adjacent to the Johnson Space Center. This is the actual Skylab trainer used by astronauts to train for life aboard a space station. The fellow floating around in the background, however, is a mannequin, although he really looked real!
