His friends apparently gave him the ring to take on his trip to the International Space Station and will get them back just before the big day.

"Weeding rings from space. Now that's a romantic gesture," Pesquet said.

An engraving on one of the rings has a date of August 14, about two months after Pesquet returns to Earth.

Pesquet himself also has a girlfriend who works at an Italian United Nations office.

He is working as a flight engineer, joined by American Peggy Whitson and Russian Oleg Novitskiy.
