History was in the making earlier this morning: two female NASA astronauts Christina Koch and Jessica Meir ventured outside the International Space Station (ISS) to make an urgent repair to its power system.

The first-ever all-female spacewalk was conducted to replace a failed power controller on the exterior of the ISS. The coverage began at 6:30 a.m. EST, with the spacewalk itself starting up at 7:50 a.m. EST. The historic moment was streamed via the official NASA TV channel on YouTube.

Although there have already been more than 200 spacewalks outside of the ISS, up until today they have been carried out by teams of two men or a man and a woman. What’s more, women only account for roughly 10 percent of the people that have ever gone to space.

This spacewalk was originally supposed to take place in March but was postponed: what happened was that NASA simply did not have two appropriately sized spacesuits readily available. The incident sparked an outcry against sexism and male domination in space.

In any case, the space industry seems to be looking into the bright future as NASA plans to put the first woman on the moon by 2024.
