All-Woman Spacewalk Makes History (Again)

Two women on the International Space Station made history once again.

NASA’s first spacewalk of 2020 started early Wednesday morning, and for the second time ever, it was an all-woman crew. 

Two flight engineers for Expedition 61, Christina Koch and Jessica Meir, suited up on January 15 and started their spacewalk at around 5:30 AM EST. 

This is only the second time ever that two women will be completing a spacewalk—and it was Koch and Meir who made history the first time. In October 2019, the two astronauts completed the first all-woman spacewalk, which was Koch’s fourth spacewalk and Meir’s first. 

The spacewalk is intended to last about six and a half hours to replace nickel-hydrogen batteries with new lithium-ion batteries. The changes will help the ISS upgrade its power system with newer batteries that hold more of a charge. 

If everything goes well on Wednesday’s spacewalk, the two will be back out in space later this week for more space station upgrades.
