On October 18, 2019, NASA made history with its first spacewalk performed by two women, Christina Koch and Jessica Meir. The mission, which began at 1138 GMT, aimed to replace a faulty power controller.
According to NASA TV, the spacewalk was a result of a rescheduled mission that was initially set for March but had to be canceled due to a lack of suitable space suits.
"Christina, you may egress the airlock," spacecraft communicator Stephanie Wilson instructed the pair as they began their mission.
The spacewalk was a significant milestone for NASA, which has traditionally been a male-dominated organization. The mission's success was seen as a step towards greater diversity and inclusion in the space agency.
Koch and Meir's spacewalk was a crucial maintenance task, as they replaced a faulty battery charge/discharge unit (BCDU) on the International Space Station. The BCDUs regulate the amount of charge that goes into the station's batteries, which are essential for the station's operation.
