US astronauts Christina Koch and Jessica Meir on Friday became the first all-female pairing to carry out a spacewalk -- a historic milestone as NASA prepares to send the first woman to the Moon.

"It symbolizes exploration by all that dare to dream and work hard to achieve that dream," Meir said after the 7-hour, 17-minute spacewalk to replace a power controller on the International Space Station.
