SECOND SPACEWALK SUCCESSFUL

With the second spacewalk in just one week aboard ISS, the planned power system upgrades to the space station are now complete.

Expedition 50 Commander Shane Kimbrough and Flight Engineer Thomas Pesquet concluded their spacewalk at 12:20 p.m. EST. During the nearly six hour spacewalk, the two NASA astronauts successfully installed three new adapter plates and hooked up electrical connections for three of the six new lithium-ion batteries on the International Space Station.

The new lithium-ion batteries and adapter plates replace the nickel-hydrogen batteries currently used on the station to store electrical energy generated by the station’s solar arrays. These new batteries provide an improved power capacity for operations with a lighter mass and a smaller volume than the nickel-hydrogen batteries. Robotic work to update the batteries began in January. This was the second of two spacewalks to finalize the installation. Additional batteries will be replaced as part of this power upgrade over the next couple of years as new batteries are delivered to station.

Astronauts were also able to accomplish several get-ahead tasks including stowing padded shields from Node 3 outside of the station to make room inside the airlock and taking photos to document hardware for future spacewalks.

Shane Kimbrough and Thomas Pesquet, during the second spacewalk in a week, mark the 197th space walking event in NASA history.

This was the second spacewalk in a week for Kimbrough and the fourth of his career, and the first for Pesquet in the refurbishment of two of the station’s eight power channels.

Space station crew members have conducted 197 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 51 days 6 hours and 4 minutes working outside the station.

Both spacewalks complement the ongoing robotics work that started at the end of December. Ground controllers have been remotely-operating the Canadarm2 robotic arm and Dextre robotic hand to remove and stow the old nickel-hydrogen batteries and the install the new batteries.
