It has been more than 286 days since NASA astronauts Butch Wilmore and Suni Williams arrived at the International Space Station. Wilmore and Williams had planned stay from June to July, but concerns about the safety of their return vehicle kept them on the station for months.

Scientists have explained everything that might happen to the two 'stranded' NASA astronauts' bodies when they finally return to Earth this month.

After nine months on the International Space Station, NASA astronauts Sunita Williams and Barry “Butch” Wilmore splashed down in the Gulf of Mexico on March 18.
