On an episode of “The Story Behind the AP Story,” Associated Press space writer Marcia Dunn discusses the space odyssey of NASA’s two stuck astronauts.

Nasa astronauts Butch Wilmore and Suni Williams have finally left the International Space Station (ISS) after an unexpected nine-month stay. Theirs has been one of the most controversial and high-profile stays on the station after the Boeing Starliner spacecraft they arrived on was deemed unsafe to be manned back to Earth.
