US astronauts Christina Koch and Jessica Meir stepped outside the International Space StationFriday morning, the first time in history that two women have done a spacewalk together.
Koch and Meir were expected to spend more than five hours outside the space station toreplace a failed power controller, but extended their spacewalk to "accomplish some get-ahead tasks on the space station," according to NASA.
The astronauts spoke with President Donald Trump and Vice President Mike Pence during thespacewalk.
The conversation marked the first time since the 1969 moon landing that a sitting presidentspoke directly to astronauts who were physically outside of a spacecraft in space, accordingto the White House.
Trump called the two astronauts "very brave people" for their service on the space station.
"I don't think I want to do it. I must tell you that. But you are amazing people," the presidentsaid, later adding, "You're very brave, brilliant women."
Meir told the president she and Koch saw the spacewalk as "just us doing our job."
"It's something we've been training for six years," she said. "For us, it's just coming out hereand doing our job today. We were the crew that was tasked with this assignment."
"At the same time, we recognize that it is a historic achievement and we do of course wantto give credit for all those who came before us," Meir added. "There has been a long line offemale scientists, explorers, engineers and astronauts and we have followed in their footstepsto get us where we are today."
Meir said she hopes she and Koch provide inspiration "to everybody, not only women."
"To everybody that has a dream, that has a big dream and that is willing to work hard to makethat dream come true, something that all of us that have made our way up here have done allthroughout our lives," she said. "And I can tell you, the hard work certainly did pay off."
The remaining four astronauts aboard the International Space Station, all men, will stay insidewhile Koch and Meir complete their work.
People took to social media Friday to celebrate "HERstory in the making," as NASA is callingthe history-making event.
Koch and Meir both joined NASA in 2013, the year NASA's astronaut class was 50% female. Koch is also on her way to making history with a 300-day mission, which will be the longestsingle spaceflight by a woman.
Koch and Meir's spacewalk comes seven months after NASA had to cancel its first attempt atmaking "HERstory," because the space station did not have enough medium-size spacesuits onboard.
Koch and another astronaut, Anne McClain, were supposed to make the first all-womenspacewalk back in March.
