Ed White became the first American astronaut to walk in space on June 3, 1965, during the Gemini 4 mission. White’s spacewalk lasted 23 minutes, during which he maneuvered around his spacecraft with the aid of a handheld jet-propulsion gun. This historic event was a major milestone in NASA’s space program, demonstrating the U.S. commitment to achieving space exploration feats, and it paved the way for future extravehicular activities, including the Apollo moon landings.
