Airman 1st Class Donald G. Farrell, talks with Fenten Duepner, an electronic engineer at the Air Force School of Aviation Medicine, during a pre-ascension briefing at Randolph Air Force Base. Farrell is inside the small shell in which he began a seven-day journey into the unknown on Feb. 9, 1958. The space cabin is designed to duplicate the conditions Farrell might encounter if he were on a trip to the moon. Photo Credit, United Press, Feb. 9, 1958
