[b]ISS Expedition 63: U.S. Spacewalk 66[/b] NASA astronauts Chris Cassidy and Bob Behnken are scheduled to exit the International Space Station's Quest airlock on Wednesday (July 1) to complete upgrading one of two power channels on the station's far starboard truss (S6 Truss). Cassidy and Behnken are expected to begin the spacewalk at about 7:35 a.m. EDT (1135 GMT). On their a prior spacewalk together on June 26, Cassidy and Behnken began the work to remove six nickel-hydrogen batteries and replace them with three new lithium-ion batteries and the adapter plates to connect the power circuit. The remaining tasks include installing one more lithium-ion battery and one more adapter plate and removing the sixth nickel-hydrogen battery that will no longer be used. In addition, the spacewalkers will loosen the bolts on a second set the nickel-hydrogen batteries, setting up their replacement during two future spacewalks. Cassidy and Behnken will also route power and ethernet cables in preparation for the installation of a new external wireless communications system supporting an enhanced HD camera and an increase to helmet camera coverage for future spacewalks. To support future power system upgrades, they will also remove a device called an "H-Fixture" that was installed before the space station's solar arrays were launched and added to the orbiting complex. This will be the 229th spacewalk in support of space station assembly and maintenance. Cassidy will be extravehicular crew member 1, wearing the spacesuit with red stripes. Behnken will be extravehicular crew member 2, wearing the spacesuit with no stripes. It will be the eighth spacewalk for each astronaut.
