Slip into the weekend while cheering on two astronauts working in the vacuum of space! At 7 a.m. EST on Friday, Mar. 5, Kate Rubins of NASA and Soichi Noguchi of JAXA (Japan Aerospace Exploration Agency) will exit the International Space Station to vent ammonia from the Early Ammonia System and complete several other tasks outside the orbital lab. Once their spacesuits are switched to battery power, the spacewalk is scheduled to last approximately six-and-a-half hours.
