Two NASA astronauts are in the middle of their six-and-a-half-hour space walk right now.
International Space Station astronauts Anne McClain and Nick Hague on Friday are outside the station installing a set of powerful batteries in the lab’s solar power system.
You can watch the spacewalk live and ask NASA questions.
This is the first spacewalk of 2019. The astronauts are swapping out old nickel hydrogen batteries with new lithium ion batteries and installing battery adapter plates. The batteries will store power generated by the station’s solar arrays to provide ISS power even when the station is away from sunlight. They started the spacewalk at 8:01 a.m. ET.
The next spacewalk, which will also involve battery replacement work, is set for March 29 with NASA astronauts McClain and Christina Koch. If it goes according to schedule, it will be the first all-female spacewalk in history.
