Two NASA astronauts are carrying out a seven-hour spacewalk. Chris Cassidy and Robert Behnken work to replace lithium ion batteries for one of the International Space Station's power channels. These batteries are big, and require two people to move them. However, they'll power the ISS for 20 years.
