 Leroy Gordon Cooper, Jr., also noted as Gordo Cooper, was born 6 March 1927 in Shawnee, Oklahoma and was an American astronaut. Cooper was one of the seven original astronauts in Project Mercury, the first manned-space effort by the United States.

Each of the Mercury astronauts was assigned to a different portion of the project along with other special assignments. Cooper specialized in the Redstone rocket (and developed a personal survival knife for astronauts to carry). He also chaired the Emergency Egress Committee, responsible for working out emergency launch pad procedures for escape. Cooper served as capsule communicator (CAPCOM) for John Glenn's first orbital spaceflight in Mercury-Atlas 6 (Friendship 7) and Scott Carpenter's flight on Mercury-Atlas 7 (Aurora 7). He was backup pilot for Wally Schirra in Mercury-Atlas 8 (Sigma 7).

Cooper was launched into space on 15 May 1963 aboard the Mercury-Atlas 9 (Faith 7) spacecraft, the last Mercury mission. He orbited the earth 22 times and logged more time in space than all five previous Mercury astronauts combined – 34 hours, 19 minutes and 49 seconds, traveling 546,167 miles (878,971 km) at 17,547 mph (28,239 km/h), pulling a maximum of 7.6 g (74.48 m/s²). Cooper achieved an altitude of 165.9 statute miles (267 km) at apogee. He was the first American astronaut to sleep not only in orbit but on the launch pad during a countdown. (Read more...)
