View of Astronaut John Glenn insertion into the Mercury Spacecraft

S62-00957 (20 Feb. 1962) --- Project Mercury astronaut John H. Glenn Jr., enters the Friendship 7 spacecraft during the last part of the countdown on Feb. 20, 1962. At 9:47 a.m. (EST), the Atlas launch vehicle lifted the spacecraft into orbit for a three-orbit mission lasting four hours, 55 minutes and 23 seconds. Glenn and his spacecraft were recovered by the destroyer Noa just 21 minutes after landing in the Atlantic near Grand Turk Island, to successfully complete the nation's first manned orbital flight.
