Spacewalk to Upgrade Space Station's Power System

On July 21, NASA astronauts Chris Cassidy and Robert Behnken will conduct a spacewalk to finish a 3.5-year effort to upgrade the International Space Station’s power system. Coverage will begin around 7:35 a.m. EDT, and could last up to seven hours. Cassidy and Behnken will replace aging nickel-hydrogen batteries with new lithium-ion batteries delivered to the station on a Japanese cargo ship in May. During this spacewalk, the last nickel-hydrogen battery will be removed from the truss and stowed.
