America is eagerly awaiting the return of two astronauts who have been stuck on the ISS since last June. Here's who they are.

Houston: SpaceX and NASA have launched a mission to bring back US astronauts Sunita Williams and Butch Wilmore from the International Space Station (ISS), where they have been stranded for nine months.

Crew-10 is the 10th crew rotation mission under SpaceX’s human space transportation system and the 11th flight with a crew aboard to the ISS station through NASA’s Commercial Crew Program, including the Demo-2 test flight. The mission was delayed on Thursday due to a hydraulic system issue with a ground support clamp arm.
