In this historical photo from the U.S. space agency, Ham tries out his combination couch and life support system in preparation for his flight in Mercury Redstone-2 (MR-2). The couch is plugged into the circuit that normally would supply the astronaut's full pressure suit.

The MR-2 flight was one in a series of flights that led to the manned orbital flights of NASA's Project Mercury program.
