While Suni Williams and Butch Wilmore’s situation is unusual, their return trip will be pretty routine, as they were already slated to fly home on a SpaceX capsule as part of a scheduled crew rotation.

Indian-origin astronaut Sunita Williams and Butch Wilmore launched aboard Boeing's new Starliner capsule in June for a week-long test flight. However, technical issues with the spacecraft led to an extended stay at the International Space Station (ISS), leaving the astronauts stranded in space.
