He was a member of the crews of Gemini 4 and Apollo 1. After graduating from West Point in 1952 with a Bachelor of Science degree, White was sent to flight ...
Astronauts James McDivitt and Ed White circled the Earth 66 times in four days, making it the first US flight to approach the five-day flight of the Soviet Vostok 5. The highlight of the mission was the first space walk by an American, during which White floated free outside the spacecraft, tethered to it, for approximately 23 minutes.
The Hand-Held Maneuvering Unit (HHMU), also known as the maneuvering gun, or informally as "the zip gun", was the first astronaut propulsion unit. It was first used by astronaut Ed White during the first American "spacewalk" (extra-vehicular activity, EVA), on Gemini 4, June 3, 1965. Different models of HHMU were present on Gemini 4, 8, 10, and ...
To date, 263 individuals representing a dozen countries have performed spacewalks, according to NASA statistics, led by Soviet cosmonaut Alexei Leonov in 1965 with NASA’s Ed White close behind.
All of these astronauts flew on Gemini, and except for White, each commanded one Gemini and one Apollo mission: Edward H. White II – Second-seat veteran of Gemini 4 who made the United States' first walk in space, selected as Senior Pilot (second seat) on Apollo 1. White was killed in the Apollo 1 fire along with Grissom and Chaffee.
This class included the first and last humans to walk on the Moon, Neil Armstrong and Eugene Cernan; Ed White, the first American to walk in space (also killed in the Apollo 1 accident); Jim Lovell, commander of the famously near-tragic Apollo 13; and John Young, whose six flights included a moonwalk and command of the first Space Shuttle mission.
The MMU during a Shuttle flight. The Manned Maneuvering Unit (MMU) is a propulsion backpack which was used by NASA astronauts on three space shuttle missions in 1984. The MMU allowed the astronauts to perform untethered EVA spacewalks at a distance from the shuttle. The MMU was used in practice to retrieve a pair of faulty communications ...
It was crewed by James McDivitt and Ed White. The highlight of the mission was the first space walk by an American, during which White remained tethered outside the spacecraft for 22 minutes. Tied to a tether, White fired his oxygen-powered "zip gun" and floated out of the capsule.
