Skylab space station
Skylab was the United States' first space station, launched uncrewed in May 1973 and occupied for about 24 weeks by three astronaut crews. Constructed from a repurposed Saturn V rocket's third stage, it served as an orbital workshop and solar observatory hosting hundreds of scientific experiments. Skylab was the world's second space station after the Soviet Salyut 1, with a pressurized volume of over 350 m3 that was not rivaled until Mir was completed in 1996. It mattered because it demonstrated that humans could live and work in space, conduct unprecedented solar observations, and perform major repairs in orbit—achievements that paved the way for future space exploration.
