Dec. 22 (UPI) -- NASA and the Russian space agency Roscosmos are evaluating if they will need to mount a rescue mission to the International Space Station after discovering a coolant leak from the Russian Soyuz spacecraft currently docked at the station.
The leaking spacecraft, designated Soyuz MS-22, carried U.S. astronaut Frank Rubio, along with cosmonauts Dmitri Petelin and Sergey Prokopyev to the International Space Station on Sept. 21.
