 The three other scheduled spacewalks scheduled to install the new batteries had to be postponed in order to perform this spacewalk.The spacewalk lasted seven hours and 17 minutes, and was the first all-female spacewalk in history.During the spacewalk US president Donald Trump called and spoke to the astronauts in recognition of the historical significance of this event, being corrected by Meir after mistakenly announcing the event as the first time a woman was outside the space station.
