NASA Astronauts Are Taking a Spacewalk Today: Watch It Live!1 min read

Two astronauts will venture outside the International Space Station today (March 22) to replace old batteries on the station’s solar arrays. This will be the first of three spacewalks scheduled to take place over the next three weeks, and you can watch them all live online!

Today, NASA astronauts Anne McClain and Nick Hague — both first-time spacewalkers — will begin the spacewalk trifecta with a planned 6.5-hour excursion outside the orbiting laboratory. They will exit the Quest airlock at 8:05 a.m. EDT (1200 GMT), NASA’s webcast will begin at 6:30 a.m. EDT (1030 GMT).

One week from now, McClain will head out for her second spacewalk together with NASA astronaut Christina Koch. That will be the first all-female spacewalk in history. During these first two spacewalks, astronauts will continue ongoing work to upgrade the space station’s power system by replacing old nickel-hydrogen batteries with new and improved lithium-ion batteries. These upgrades began in 2017, when NASA astronauts Shane Kimbrough and Peggy Whitson and European Space Agency astronaut Thomas Pesquet swapped out the first set of batteries in a pair of back-to-back spacewalks.
