A pair of Russian cosmonauts and a Nasa astronaut face spending a year in space after a micrometeorite sparked fears for the safety of their return.
Sergey Prokopyev, Dmitry Petelin and astronaut Francisco Rubio were rocketed to the International Space Station last September for a six-month mission, 248 miles above planet Earth.
However a micrometeoroid - a tiny speck of dust travelling through space - is feared to have damaged their ride home, causing a leak in the Soyuz MS-22.
