   Explanation: 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 Meir, the first for
   Koch, 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 Weir 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.
