US astronauts Christina Koch and Jessica Meir became the initial all-female pairing to conduct a spacewalk Friday, after a spacesuit flub before this season that resulted in the historic mission to be aborted.
“Christina, you might egress that the airlock,” spacecraft communicator Stephanie Wilson advised the pair soon after they started their assignment to replace a power control in 1138 GMT.
The first such mission was designed to occur in March but had to be canceled since the space agency had just one medium-sized lawsuit, using a male-female mix performing the essential task at a subsequent date.
Koch is top Meir, who’s making her first spacewalk.
Both will replace a faulty battery charge/discharge device (BCDU).
The channel relies on solar energy but is from direct sun for much of its orbit and so needs batteries, and also the BCDUs regulate the quantity of charge which goes to them.
