World's most experienced spacewoman Whitson returns to Earth
NASA astronaut Peggy Whitson, the world's most experienced spacewoman, has returned to Earth after clocking cumulative 665 days in space. The 57-year-old landed on Sunday after completing 288 days and 4,623 orbits around Earth during her third ISS mission. Whitson, also the only woman to command $100-billion ISS twice, earlier broke Sunita Williams' record of most spacewalks by a woman.
