They will be supported by women on the ground, including flight director Mary Lawrence and control team member Kristen Facciol. She was followed almost 20 years later by the second woman in space, Svetlana Savitskaya, who also did a spacewalk two years later.
It's about time we've had an all-female spacewalk.
The expedition will comprise six crew members, including the two female astronauts who are scheduled for the spacewalk. Facciol will support and maintain communication with the astronauts during their spacewalk from the console at the Johnson Space Center in Houston.
The spacewalk will be the second of three planned spacewalks during Expedition 59 to upgrade batteries on the International Space Station, which were delivered on the Japanese HII-Transfer Vehicle last summer, according to NASA.

McClain and Koch were part of the 2013 NASA class that was 50 percent women.
Nasa has kept the world on its toes by announcing that they have organized and will execute an All woman Space Walk on the 29th of March 2019. Prior to joining NASA, McClain graduated from the U.S. Military Academy and was a test pilot. But women are finally pulling ahead in the space race.
The walk is the first of its kind ever since a Soviet woman Svetlana Savitskaya walked on July 25, 1984 in space.
Speaking on incidentally being able to make history on Women's History Month, Koch had said: "It is a unique opportunity and I hope I'm be able to inspire folks that might be watching".
