In Pictures: Most experienced spacewoman returns to Earth
World's most experienced spacewoman Peggy Whitson returned to Earth after clocking cumulative 665 days in space, also the most by a NASA astronaut. The 57-year-old landed in Kazakhstan on Sunday after her third ISS mission, during which she broke Sunita Williams' record for most spacewalks by a woman. Whitson was accompanied by fellow astronaut Jack Fischer and a Russian crewmate.
