In this historical photo from the U.S. space agency, John H. Glenn, one of the Mercury Seven Astronauts, runs through a training exercise in the Mercury Procedures Trainer at the Space Task Group, Langley Field, Virginia. This Link-type spacecraft simulator allowed the astronaut the practice of both normal and emergency modes of systems operations.
