CAPE CANAVERAL, Fla. Space-wavering astronauts deal with battery and cable problems outside the International Space Station.
It's the third time in the universe for just two and a half weeks to crew the cell.
NASA astronaut Anne McClain and Canadian astronaut David Saint-Jacques started early on Monday morning. It is necessary to complete the battery changes that began last month and lay the cable.
New cables will provide auxiliary power circuit for the Canadian robotic arm and expand wireless communication. Battery operation involves reinstalling two old batteries. One of the six new lithium-ion batteries does not work, and an out-of-date pair of nickel-hydrogen must return to the groove.
NASA says it will send another new battery.
