U.S. astronauts soar in first all-female spacewalk

History was made Friday in outer space.

For the first time ever - there was an all-female spacewalk.

Astronauts Christina Koch and Jessica Meir stepped outside of the International Space Station in order to replace batteries on equipment located on station's exterior.

The two women were tethered to the space station, floating about 254 miles above earth, leaving their hands free to perform the routine maintenance.

This historic spacewalk was supposed to happen back in March with Koch and another female astronaut - Anne McClain - but that was scrapped when it was discovered there were no adequately-sized spacesuits on board.

Koch is on her way to making more history as the longest single space flight by a woman remaining in orbit aboard the station until February 2020.
