French astronaut Thomas Pesquet emerged from the airlock shortly after Kimbrough.

Glove Check

NASA astronaut and current commander of the International Space Station Shane Kimbrough floats weightlessly next to two spacesuits. Kimbrough and the Expedition 50 crew performed routine maintenance on the spacesuits throughout December to prepare for spacewalks coming up in January 2017.

Peggy Whitson Sends Them Off

If you look closely, you’ll spot NASA astronaut Shane Kimbrough working on the space station’s truss. Below him are the space station’s solar panels.

Kimbrough is seen working with his headlights on as the space station passes over the nighttime side of the Earth.

Retrieving the Adapter Plates

Kimbrough (bottom) and Pesquet (top) work to remove the adapter plates from the external palette so they can be installed onto the power grid.

Lugging Equipment

Kimbrough and Pesquet used body tethers to attach the adapter plates to their spacesuits before carrying them down the truss to the power assembly.

Power Tools

The astronauts carry a bag with tools during the spacewalk. One of those tools is a power drill used to turn bolts and screws.

Working Along the Truss

Kimbrough (left) and Pesquet (right) are seen working their way down the space station’s truss, the “backbone” of the station’s structure.

Storing the Old Batteries

The station’s old nickel-hydrogen batteries were placed back onto the external palette for storage.

Pesquet at the ‘Rat’s Nest’

With time left to spare, Pesquet visited the “rat’s nest,” a jumble of cables outside the ISS, to take photos for flight planners on the ground. The survey photos will help them prepare for future spacewalking tasks.

Pit Stop

The duo made a pit stop at the Quest airlock from which they emerged this morning to drop off some tools and pick up padded shields, which they then carried to the Node 3 or “Tranquility” module. Located at this module are six berthing locations where visiting spacecraft can dock to the ISS.

The shields will protect one of Tranquility’s pressurized mating adapters from potentially hazardous collisions with space debris.

Kimbrough & the Destiny Lab

Kimbrough heads to the U.S. Destiny Laboratory to remove two unnecessary handrails, making room for two communication antennas that will be installed in future spacewalks.

Peggy Whitson takes photos of the spacewalkers’ gloves, which will later be closely examined by the ground team to check for damages incurred during the spacewalk.

Installing New Lithium-Ion Batteries

This diagram shows how the new lithium-ion batteries and adapter plates are configured with the old nickel-hydrogen batteries.

Before & After

This diagram shows the configuration of batteries and adapter plates before and after the spacewalk. Adapter plates were removed from the HTV-6 cargo craft and installed at the station’s integrated electronics assembly (IEA) to complete the replacement of nickel-hydrogen batteries with lithium-ion batteries.

Mission Control
