NASA astronauts Jessica Meir and Christina Koch went into space today. They are the first all female spacewalk crew, making this a very historic event. The spacewalk outside of the International Space Station lasted for seven hours and 17 minutes and ended at 2:55 p.m. ET. time.

This was the fourth spacewalk for Christine Koch, and the first for Jessica Meir, and both said the event went well. According to the International Space Station Twitter page, the two 'successfully replaced a failed power controller with a spare that is now activated and charging a new lithium-ion battery.'  Check out video of the historic event below. Congratulations, ladies, well done!
