Skylab

This onboard photograph depicts Astronaut Owen Garriott atop the Apollo Telescope Mount, removing a film magazine (white box) from one of Skylab's solar telescopes during an Extravehicular Activity (EVA) in the second marned Skylab mission (Skylab-3). A long boom transported it back into the waiting hands of another crew member at the airlock door below. During the operation, Garriott, film, boom, and Skylab were 435 kilometers high and speeding around the Earth at 29,000 kilometers per/hour. Because they moved together with no wind resistance, there was little sense of motion.
