During the Mercury program, which sent humans into space for a short period of time in preparation for the Apollo lunar missions, most of the equipment carried was standard military issue. The Apollo kits differed considerably because most of its items were designed and built specifically for use by astronauts.
These items were carried aboard the one-man Mercury missions by Alan B. Shepard on the flight of Freedom 7 in May 1961 and John H. Glenn Jr. on the flight of Friendship 7 in February 1962.
In order to maintain health like they would on Earth—but in a very limited space—Apollo astronauts needed to have special equipment.
All of these items, carried on Apollo 11 in July 1969, allowed the astronauts to exercise, maintain personal hygiene, and monitor their health during the flight.
