The launch of the Mercury-Redstone (MR-3), with “Freedom 7” capsule, on May 5, 1961. (NASA) The rocket burned for a little over two minutes with the acceleration ramming him into his couch with a force of over six “Gs” (six times Earth’s gravity).
By today's standards, Mercury Redstone 3 was a very simple suborbital mission, but in 1961 it was proof that the United States had mastered the technology to send a human being safely into...

In this collection of technical diagrams, details of the Mercury-Redstone launch vehicle and the Mercury spacecraft come to light.
Mercury Redstone 3 (MR-3, also designated Freedom 7) was the first flight of an American rocket with a human on board (Alan B. Shepard, Jr.), occurring twenty-three days after Yuri Gagarin's orbital flight of Vostok 1.
The Mercury-Redstone Launch Vehicle, designed for NASA's Project Mercury, was the first American crewed space booster. It was used for six sub-orbital Mercury flights from 1960–1961; culminating with the launch of the first, and 11 weeks later, the second American (and the second and third humans) in space.
On May 5, 1961, Alan Shepard became the first American in space in this Mercury capsule. He named it "Freedom 7," the number signifying the seven Mercury astronauts; NASA called the mission Mercury-Redstone 3 (MR-3). Lofted by a Redstone rocket, Shepard and his capsule attained a maximum speed of 5180 mph and rose to an altitude of 116 miles.
