International Space Station July 16, 2020: NASA Spacewalk

Today’s NASA Spacewalk to be undertaken by astronauts Behnken and Cassidy will be mirroring the work they completed in their first spacewalk on June 26, 2020. According to NASA’s official website, the primary tasks for the crew will be to remove five of six older nickel-hydrogen batteries for the truss’ power system. And in place of these old batteries, three new lithium-ion batteries will be placed.

These lithium-ion batteries store electricity for one pair of the station’s solar arrays. During the NASA Spacewalk, the astronauts will be installing two of three adapter plates to complete the circuit to the new batteries. They will also be relocating the nickel-hydrogen batteries for storage and for future disposal. Leading this tedious mission today is NASA's Flight Director Allison Bolinger in the NASA. She will be supported by another NASA official Sandy Moore as the lead spacewalk officer. Astronauts Chris Cassidy and Robert Behnken are scheduled to conduct another NASA Spacewalk on Tuesday, July 21. The July 21 Spacewalk will mark the end of a 3.5-year effort to upgrade the International Space Station’s power system.
