NASA astronauts Peggy Whitson and Jack Fischer each took part in a spacewalk recently on board the International Space Station to repair a faulty computer and install a data cable on the craft. The repairs took the crew three hours which was long enough to circle the earth nearly twice.
Whitson, the current commander of the ISS, spent enough time outside to reach third place for most time spend on spacewalks at 60 hours and 21 minutes.
And while an emergency spacewalk isn’t entirely rare, it’s not common either. The last emergency walk occurred in 2015.
