At 10:06 a.m. EDT, spacewalkers Steve Bowen and Michael Good installed a second battery, battery B, on one of the four solar arrays on the International Space Station. The STS-132 mission delivered a total of six new batteries to the station. Bowen and Good will install three batteries today and a fourth if time permits. The remaining batteries will be installed during the third spacewalk on Friday.
The batteries are recharged during the sunlit phase of each orbit around Earth and provide a continuous power source to the station during the shadow phase.
The spacewalkers completed the installation about three and a half hours into today’s spacewalk.
