The Spacewalks of Expedition 59 in Photos

During the Expedition 59 mission to the International Space Station, astronauts are doing a series of three spacewalks.

On March 22, 2019, NASA astronauts Anne McClain and Nick Hague took a spacewalk to replace some aging nickel-hydrogen batteries with new lithium-ion batteries. One week later on March 29, Hague and NASA astronaut Christina Koch did similar work on their spacewalk together, replacing a second set batteries.

The third spacewalk of Expedition 59 will take place on April 8, when McClain and Canadian Space Agency astronaut David Saint-Jacques will work to establish a redundant power supply to the Canadarm2 robotic arm and upgrade the station's wireless networks.

See photos of the astronauts working in space in this gallery! We'll update this gallery with the latest spacewalk photos once the astronauts beam more of them down to Earth.

NASA astronaut Nick Hague is pictured inside the Quest airlock at the beginning of his first spacewalk on March 22, 2019. He and NASA astronaut Anne McClain spent 6 hours and 39 minutes working in the vacuum of space to replace six old nickel-hydrogen batteries with three new lithium-ion batteries on the station's P4 truss, a segment that is connected to one of the eight solar arrays.

NASA astronaut Nick Hague also took a selfie during that first spacewalk, but he had his sun visor down. You can see the reflection of his camera on his helmet.

This view of spacewalker Anne McClain shows how enormous the space station's solar panels are compared to a human being.

NASA astronaut Anne McClain looks delighted to be working in space in this photo taken shortly after the start of her very first spacewalk on March 22, 2019.

NASA astronaut Christina Koch took her first spacewalk on March 29, 2019, together with Nick Hague. If you look closely, you can see Hague's legs dangling behind Koch. During this spacewalk, Hague wore the suit with the red stripes, and Koch wore the plain white suit.

At the beginning of their May 29, 2019, spacewalk, cosmonauts Alexey Ovchinin and Oleg Kononenko wished Alexei Leonov, the first person to perform a spacewalk, a happy upcoming 85th birthday. The Russian duo also brought a picture of Leonov (seen in the golden frame) into space with them.
