NASA astronauts Jessica Meir and Christina Koch stepped into the vacuum of space for a history-making spacewalk outside of the International Space Station on Friday.

Why it matters: While American women have been flying in space since Sally Ride made her first trip to orbit in 1983, today's spacewalk marks the first all-female spacewalk in history.

Details: Koch and Meir were expected to go for their first spacewalk on Oct. 21, but a power issue on the station forced mission managers to plan Friday's walk first, delaying the Monday spacewalk and others in the series.

  • The two astronauts will change out a battery charging unit that collects energy from the station's solar arrays, NASA said in a statement, adding that the unit's failure presents no harm to the orbiting outpost or its astronauts.
  • This is Koch's fourth spacewalk and Meir's first, and it is expected to take 5 to 6 hours.
  • The two women are self-proclaimed "best friends."

Between the lines: While women made up half of Meir and Koch's 2013 astronaut class, women comprise about 34% of NASA's workforce as a whole, and 23% of the agency's science and engineering employees, according to agency statistics.

Scoop: How the White House is trying to trap leakers

President Trump's chief of staff, Mark Meadows, has told several White House staffers he's fed specific nuggets of information to suspected leakers to see if they pass them on to reporters — a trap that would confirm his suspicions. "Meadows told me he was doing that," said one former White House official. "I don't know if it ever worked."

Why it matters: This hunt for leakers has put some White House staffers on edge, with multiple officials telling Axios that Meadows has been unusually vocal about his tactics. So far, he's caught only one person, for a minor leak.

11 GOP congressional nominees support QAnon conspiracy

At least 11 Republican congressional nominees have publicly supported or defended the QAnon conspiracy theory movement or some of its tenets — and more aligned with the movement may still find a way onto ballots this year.

Why it matters: Their progress shows how a fringe online forum built on unsubstantiated claims and flagged as a threat by the FBI is seeking a foothold in the U.S. political mainstream.
