Explained: Why Boeing Starliner Will Return Without Sunita Williams

Indian-origin astronaut Sunita Williams and her NASA colleague Butch Wilmore, who arrived at the International Space Station (ISS) aboard crisis-hit Boeing's Starliner in June, will return home with billionaire Elon Musk's SpaceX next year. The two veteran astronauts were launched to the ISS on June 5 for what was expected to be an eight-day test mission. Their homecoming, however, was delayed for weeks by thruster malfunctions of the Boeing spacecraft, and NASA announced Saturday they will return to Earth in February next year. Starliner will return to Earth uncrewed.
