Honoring the 50th Anniversary of NASA’s Skylab: America's First Space Station

America’s first space station and the first crewed research laboratory in space, Skylab, lifted off on May 14, 1973.

Skylab helped pave the way for permanent operations in low-Earth orbit. Over the course of its human occupation from May 25, 1973, to Feb. 8, 1974, three crews visited Skylab, carrying out 270 scientific and technical investigations in astronauts’ physiological responses to long-duration space flight, Earth sciences, solar physics, and astronomy.
