NASA astronauts Chris Cassidy and Robert Behnken have begun the second of two scheduled spacewalks to replace batteries on one of two power channels on the far starboard truss (S6 Truss) of the International Space Station.

The spacewalkers switched their spacesuits to battery power at 7:13 a.m. EDT to begin the spacewalk, which may last as long as seven hours. Watch the spacewalk on NASA TV and on the agency’s website.

Behnken and NASA astronaut Doug Hurley arrived at the space station in May aboard SpaceX’s Crew Dragon as part of NASA’s Commercial Crew Program’s Demo-2 mission. The end-to-end test flight is designed to validate the SpaceX crew transportation system, including launch, in-orbit, docking and landing operations, paving the way for its certification for regular crew flights to the station.
