All Female Spacewalk Repairs Space Station

The failed unit was beyond the reach of the robotic Canadarm2 . Therefore, this repair of the International Space Station would require humans. The humans on duty were NASA's Jessica Meir and Christina Koch . This was the fourth spacewalk for Koch, the first for Meir, and the first all-female spacewalk in human history . The first woman to walk in space was Svetlana Savitskaya in 1984. Koch (red stripe) and Meir are pictured hard at work on the P6 Truss , with solar panels and the darkness of space in the background. Working over seven hours , the newly installed Battery Charge / Discharge Unit (BCDU) was successfully replaced and, when powered up, operated normally.
