Skylab

Skylab (here in virtual LEGO form by iPaloosa) was a space station operated by NASA in the early 1970s. Scientific missions included close observations of solar activity and studies on the long term effects of microgravity on the astronauts (to consider the long term feasibility of living and working in space). In 1979, atmospheric drag caused the space station to lose altitude and then fall back to earth, with debris landing near Perth, Australia.
