Gemini III was supposed to test spacecraft maneuvers and prove America could handle two men in orbit. Instead, it became famous for something far more down-to-earth: a smuggled corned beef sandwich.

Astronaut John Young tucked the deli special into his spacesuit pocket, courtesy of Wally Schirra, and surprised Gus Grissom mid-flight. For a moment, outer space smelled like a New York deli. But the laughter didn’t last — crumbs floated free in zero-G, raising alarms about what could happen if one drifted into the controls.

Congress wasn’t laughing, NASA tightened the rules, and the “space sandwich” went down in history as the snack that changed spaceflight policy.
