57-year-old NASA astronaut Peggy Whitson broke the record for the most spacewalks ever performed by a woman when she ventured out of the International Space Station on Thursday. Whitson, who The Associated Press noted is "the world's oldest and most experienced spacewoman," has now completed eight spacewalks, surpassing former space station resident Sunita Williams' record of 50 hours and 40 minutes of spacewalking time. Whitson also holds the record for the most time a woman has ever spent in space, as she's now up to more than 500 days away from Earth. Whitson departed for her third space station trip in November to set up a docking port for commercial crew ships being developed by Boeing and SpaceX. She is slated to return in June.
