This NASA TV video grab shows the U.S. astronaut Peggy Whitson outside the International Space Station on March 30, 2017. Peggy Whitson, 57, completed her record-breaking eighth spacewalk despite a minor setback when a piece of thermal shielding being installed outside the International Space Station slipped away and drifted into space. Mission Commander Shane Kimbrough and Whitson, the flight engineer, conducted a variety of maintenance tasks over several hours. Whitson, an Iowa native on her third mission to the station, broke records for most spacewalks by a woman with eight, and most hours spent spacewalking with more than 50. (Photo/NASA)
