Sunita Williams, an Indian astronaut, is set to launch into space as the first female pilot of a newly developed human-rated spaceship.
She has previously made two space flights and has spent a total of 322 days in space.
Williams is preparing for her third trip on the International Space Station and the Crew Flight Test mission, which will be the first crewed flight for Boeing's Starliner spaceship.
The CST-100 Starliner spacecraft, designed by Boeing, can carry seven people on low-Earth orbit flights and has been in development for almost ten years.
