In 1965, during NASA’s Gemini 4 mission, astronaut Ed White used a handheld maneuvering gun to control his movement while tethered outside the spacecraft. The simple device used compressed gas to push him gently through microgravity, proving that astronauts could actively navigate and work in open space, a critical step toward future space stations and deep-space missions.
