77-Tonne Skylab Breaks Up Over Western Australia After 6 Years in Orbit

Summary
Large pieces of the 77-tonne Skylab survived re-entry on 11 July 1979, scattering across Western Australia around Esperance after the station broke apart over the Indian Ocean and inland areas.
More than six years after launch, the empty station fell because strong solar activity heated the upper atmosphere, increased drag and left Skylab unable to maintain or raise its orbit.
NASA had hoped to preserve the station for a future Shuttle revisit, but Shuttle delays ended that option; controllers could only adjust Skylab’s attitude to influence, not precisely control, where it came down.
Three crews totaling nine astronauts had lived aboard Skylab for 28, 59 and 84 days, returning about 175,000 solar images and proving the value of long-duration orbital science.
Some debris later entered museums and private collections, underscoring how a roughly $2.2 billion program that pioneered U.S. space-station living ended as tangible wreckage on the Australian landscape.
