Tennessee Tech University is celebrating the safe return of NASA astronaut Barry "Butch" Wilmore, after an unintended nine-month mission at ISS.

Astronauts Barry ‘Butch’ Wilmore and Suni Williams face unique challenges following their return home after being stranded on the International Space Station for nine months

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.
