US makes history with first all-female spacewalk
US astronauts Christina Koch and Jessica Meir became the first all-female pairing to carry out a spacewalk yesterday, following a spacesuit flub earlier this year that caused the historic mission to be aborted. “Christina, you may egress the airlock,” spacecraft communicator Stephanie Wilson told the pair shortly after they set out to replace a power controller on the International Space Station at 1138 GMT. They began their mission making standard safety checks on their suits and tethers, before making their way to the repair site. In a call to reporters a few minutes earlier, Nasa administrator Jim Bridenstine emphasized its symbolic importance.
