Sunita "Suni" Williams had an unexpectedly long stay at the International Space Station after her capsule malfunctioned.

NASA astronauts Barry Wilmore and Sunita Williams return after 9 months in space, revealing shocking physical transformations.

Williams and Wilmore were wheeled off the spacecraft on stretchers, a standard practice for NASA astronauts, according to E! News. The protocol is due to the change in gravity, especially for Williams and Wilmore, who have been away for nine months.
