NASA astronauts Robert Kimbrough and ESA Thomas Sands replaced the battery in the ISS. This would have to go into space. The broadcast job execution led Agency NASA.
Kimbrough has walked in space four times. For the Sand it’s first flight and first spacewalk.
As part of the job, the astronauts were at 14:22 Moscow time to the spacewalk and install three lithium-ion batteries, which are delivered to the station in December. Previously, Kimbrough together with Peggy Whitson connected three lithium-ion batteries in space.
New batteries have higher energy content compared to the hydrogen-Nickel. Batteries are cheaper to operate than model modules.
