On April 12, 1981 - exactly 20 years after Yuri Gagarin's historic flight - NASA pulled off something no one had done before: launching a spacecraft that could fly back home and be used again. The Space Shuttle Columbia blasted off from Kennedy Space Center with astronauts John Young and Robert Crippen on board. The mission was called STS-1, and it changed what spaceflight looked like forever.
Until that morning, every rocket ever launched had been a one-shot deal - burn up, fall apart, splash down. The Space Shuttle was different. It looked like a chunky white airplane strapped to a giant orange fuel tank and two skinny solid rocket boosters. After two days zipping around Earth, Columbia glided down through the atmosphere and landed like a plane on a dry lake bed at Edwards Air Force Base in California. The whole world watched it touch down on wheels.
Five shuttles eventually flew 135 missions over 30 years, carrying astronauts to fix the Hubble Space Telescope and build the International Space Station piece by piece. The program had heartbreaks too - the loss of Challenger in 1986 and Columbia itself in 2003 - but the shuttle proved that reusable spaceships were possible. Today's rockets from companies like SpaceX land themselves on barges and launchpads, and every one of them owes a debt to Columbia's first daring flight.
