Mercury-Atlas 6 (MA-6) was the first crewed American orbital spaceflight, which took place on February 20, 1962. [4] Piloted by astronaut John Glenn and operated by NASA as part of Project Mercury, it was the fifth human spaceflight, preceded by Soviet orbital flights Vostok 1 and 2 and American sub-orbital flights Mercury-Redstone 3 and 4.
It was a highly publicized mission due to former Project Mercury astronaut and United States Senator John H. Glenn Jr.'s return to space for his second space flight. At age 77, Glenn became the oldest person to go into space, a record that remained unbroken for 23 years until 82-year-old Wally Funk flew on a suborbital flight on Blue Origin NS ...
John Glenn, the third Mercury astronaut to fly, became the first American to reach orbit on February 20, 1962, but only after the Soviets had launched a second cosmonaut, Gherman Titov, into a day-long flight in August 1961. [222] Three more Mercury orbital flights were made, ending on May 16, 1963, with a day-long, 22 orbit flight. [149]
He qualified as a test pilot with Class 12 at the U.S. Naval Test Pilot School in 1954. In 1957, he made the first supersonic transcontinental flight across the United States.

Mercury-Atlas 7, launched May 24, 1962, was the fourth crewed flight of Project Mercury. The spacecraft, named Aurora 7, was piloted by astronaut Scott Carpenter. He was the sixth human to fly in space. The mission used Mercury spacecraft No. 18 and Atlas launch vehicle No. 107-D. The flight was for three Earth orbits, essentially a repeat of ...
t. e. Spaceflight began in the 20th century following theoretical and practical breakthroughs by Konstantin Tsiolkovsky, Robert H. Goddard, and Hermann Oberth, each of whom published works proposing rockets as the means for spaceflight. [a] The first successful large-scale rocket programs were initiated in Nazi Germany by Wernher von Braun.
New Glenn is a heavy-lift launch vehicle developed by Blue Origin, named after NASA astronaut John Glenn, the first American astronaut to orbit Earth. [8] New Glenn is a two-stage rocket with a diameter of 7 m (23 ft). Its first stage is powered by seven BE-4 engines that are also designed and manufactured by Blue Origin.
