UPDATE: This event has concluded. You can see highlights in the video above. Earlier reporting below.
Two astronauts will venture outside the protective confines of the International Space Station on Friday to work on an important power supply upgrade.
NASA astronaut Shane Kimbrough and French astronaut Thomas Pesquet of the European Space Agency are scheduled to spend a little more than six hours installing new lithium-ion batteries and adapter plates, which you can follow along via the video above.
The spacewalk is Kimbrough's fourth and Pesquet's first, according to Space.
Pesquet tweeted about his excitement for his first spacewalk the night before, sharing a picture of the truss he'll be working along.
He also shared the music he was listening to as he pumped himself up for the big walk.
Kimbrough, who has already had the adventure of a spacewalk, didn't tweet any anticipatory messages, but he is a prolific photographer. He's snapped dozens of shots of cities and other majestic sights on Earth from the ISS -- from New York City just this week to the Holy Land.
