Last May, the astronauts aboard the International Space Station (ISS) started Expedition 36, beginning a 166-day mission conducting experiments in microgravity while orbiting the Earth more than 2,500 times. Some of the research goals for Expedition 36 included investigations into the effects of weightlessness on human eyesight, micro-satellites designed to work in teams, and the evaporation and combustion of new liquid fuels. The crew of six astronauts from the United States, Russia, and Italy also took hundreds of photographs of life aboard the ISS and the spectacular views from orbit. Collected here are scenes from Expedition 36, which concluded earlier today with the safe touchdown of a Soyuz spacecraft in a remote location in Kazakhstan.
