Astronaut Peggy Whitson is no stranger to breaking barriers: In addition to becoming the first woman commander of the International Space Station (ISS), the Iowa native has logged 377 days in space between two missions -- the most of any American spacewoman to date. Now, on her third mission aboard the ISS, Whitson is racking up even more impressive feats -- today, she performed her eighth spacewalk, setting the record for most spacewalks performed by a woman.
