Twenty-Three Minutes Outside

On June 3, 1965, Ed White opened the hatch of Gemini 4 and pushed himself into the void. He was 120 miles above the Pacific, traveling at 17,500 miles per hour, tethered by a 25-foot umbilical cord. He held a handheld gas-powered gun that let him control his movement. For twenty-three minutes, he floated free, somersaulting and drifting. His crewmate James McDivitt photographed through the open hatch. One image would be included on the Voyager Golden Record.

The Soviets had beaten America by three months. Alexei Leonov performed the first spacewalk on March 18, 1965, during Voskhod 2. His suit ballooned so much he barely fit back through the airlock. He had to bleed off pressure to squeeze inside. The Soviets released triumphant footage but omitted how close it came to disaster.

White's walk was longer, smoother, more controlled. When mission control told him to come back, he said it was the saddest moment of his life. What White proved was that humans could work outside a spacecraft without being killed by radiation, temperature extremes, or micrometeoroids. Spacewalking would become routine -- astronauts would repair satellites, build the ISS, conduct experiments outside the shuttle.

White never walked in space again. On January 27, 1967, he died alongside Gus Grissom and Roger Chaffee in a fire during a pre-launch test for Apollo 1. He was thirty-six. NASA redesigned the hatch. The program continued. His photograph remains one of the defining images of the space age -- weightless, backlit, alone against the black, doing something that looks less like work and more like freedom distilled.
