Koch arrived at the orbiting laboratory in March 2019 and remained in space for an extended duration mission to provide researchers the opportunity to observe effects of long-duration spaceflight on a woman to prepare for human missions to the Moon and Mars.
On October 18, 2019, NASA spacewalkers Koch and Jessica Meir replaced a battery charge-discharge unit with a new one during a spacewalk. (Credit: NASA TV). Expedition 61 was the first with only women.
During the 7-hour, 17-minute spacewalk, the two NASA astronauts completed the replacement of a battery charge-discharge unit (BCDU). The BCDU regulates the charge to the batteries that collect and distribute solar power to the orbiting lab’s systems.
According to NASA, the astronauts were also able to accomplish the installation of a stanchion on the Columbus module for support of a new external ESA (European Space Agency) payload platform called Bartolomeo scheduled for launch to the station in 2020.
Other history-making facts
It was the first spacewalk for Meir and the fourth for Koch, who has spent a total of 27 hours and 48 minutes spacewalking.
It is the first spaceflight for both women, who were selected in the 2013 astronaut class that had equal numbers of women and men.
Meir became the 15th woman to spacewalk, and the 14th U.S. woman.
It was the 43rd spacewalk to include a woman.
Women have been performing spacewalks since 1984 when Russian cosmonaut Svetlana Savitskaya spacewalked in July and NASA astronaut Kathryn Sullivan spacewalked in October.
