Mercury capsule #19 was one of twenty spacecraft built for the first American human spaceflight project, which aimed to put a man in orbit. Sent to the launch site, Cape Canaveral, on March 20, 1962, it became the back-up spacecraft for the Mercury-Atlas flight (MA-8) of Walter M. Schirra, who made 6 orbits of the Earth on October 3, 1962. Thereafter the mission for #19 was canceled and parts were used on other Mercury projects. In early 1968, NASA Manned Spacecraft Center (now Johnson Space Center) gave this vehicle to the Smithsonian.
