Earth views from the International Space Station. City lights, auroras, sunsets, oceans, moon on the horizon an other beauty shots of our planet from space.

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. The research conducted on Skylab helped prepare NASA for living and working in space on the International Space Station, and our journey to the Moon, Mars, and beyond.
