At 9:05 a.m. EDT, spacewalkers Steve Bowen and Michael Good installed the first of three new batteries, battery A on the B side of one of the four solar arrays on the International Space Station.
Each battery has 8 kilowatt-hours of energy, enough to run a 100 watt bulb or LCD television for 80 hours. The space station has 24 of these batteries for a combined total of 192 kilowatt-hours of energy, enough to run the average U.S. home for about six days.
The spacewalkers completed the installation at two hours and 27 minutes into today’s spacewalk.
