We wish a happy 93rd birthday to original Mercury astronaut and former U.S. Senator John Glenn! Glenn wearing a Mercury pressure suit, is photographed at Cape Canaveral, Florida, during preflight training activities for the Mercury-Atlas 6 (MA-6) mission. Glenn made America's first manned Earth-orbital spaceflight on Feb. 20, 1962. Launched from Cape Canaveral (Florida) Launch Complex 14, he completed a successful three-orbit mission around the earth, reaching a maximum altitude (apogee) of approximately 162 statute miles and an orbital velocity of approximately 17,500 miles per hour. Glenn's "Friendship 7" Mercury spacecraft landed approximately 800 miles southeast of Cape Canaveral in the vicinity of Grand Turk Island. Mission duration from launch to impact was 4 hours, 55 minutes, and 23 seconds. Image Credit: NASA #happybirthday #nasa #space #mercury #friendship7 #astronaut
