NASA plans to carry out the world’s first all-female spacewalk as soon as tomorrow.
It comes after a botched first attempt that was scrapped after Nasa ran out of spacesuits for female astronauts.
Now astronauts Christina Koch and Jessica Meir will head outside the International Space Station to make history.
The spacewalk will take place on either Thursday or Friday.
Their mission will be to replace a power controller unit that failed on the weekend.
Koch and Meir and two of six ISS members in total, and will spend several hours outside the ISS.
Nasa cancelled its first planned all-female spacewalk back in March.
Koch and and fellow astronaut Anne McClain had been scheduled to carry out the first-of-its-kind mission outside the International Space Station on March 22.
But a wardrobe malfunction meant McClain was replaced by a man on the zero-gravity maintenance job, which involves installing new batteries on the orbiting space lab.
Problems arose during a spacewalk a week earlier led by McClain and fellow astronaut Nick Hague, Nasa said.
McClain realised she needed a different sized spacesuit for Friday’s mission, but Nasa only had one in this size.
“Koch had been scheduled to conduct this spacewalk with astronaut McClain, in what would have been the first all-female spacewalk,” Nasa said in a statement at the time.
“However, after consulting with McClain and Hague following the first spacewalk, mission managers decided to adjust the assignments, due in part to spacesuit availability on the station.
“McClain learned during her first spacewalk that a medium-size hard upper torso – essentially the shirt of the spacesuit – fits her best. Because only one medium-size torso can be made ready by Friday, March 29, Koch will wear it.”
McClain is now back on Earth, and is currently being investigated by Nasa over what may be the first crime in space.
She is alleged to have accessed her estranged wife’s private financial records while aboard the ISS.

The first woman to perform a spacewalk was the Soviet cosmonaut Svetlana Savitskaya, 35 years ago.
Since then, more than 500 people have been into space, but only 55 of these have been women.
In other news, Nasa recently revealed a stunning photo of the ISS passing in front of a rare “spotless sun”.
This stunning photo of a 2,300-foot volcano erupting was captured from space by a Nasa astronaut on the ISS.
And Nasa plans to let tourists visit the ISS from 2020, but each trip could cost around £39million.
