Russia is sending a new Soyuz spacecraft to the International Space Station to act as a lifeboat for three crew members after their original ride back to Earth sprung a major coolant leak.
Russia is sending a new Soyuz spacecraft to the International Space Station to act as a lifeboat for three crewmembers after their original ride back to EarthEven though the ISS has been continuously occupied by astronauts and cosmonauts for more than 20 years, this technical issue highlights the dangers of living there.A Soyuz capsule that is docked to the ISS and responsible for carrying crewmembers back to Earth began to leak coolant into space in December.
Roscosmos has now decided that it's too risky to bring home the crewmembers aboard the leaky Soyuz, opting instead to send up another empty Soyuz to transport NASA's Frank Rubio and cosmonauts Sergey Prokopyev and Dmitri Petelin back to Earth. Mission managers are worried, however, that the crew area of the damaged Soyuz would overheat during its return journey to Earth, putting the crewmembers in danger.
"SpaceX has been extremely responsive," NASA's Joel Montalbano said during a press conference Wednesday. "But all of this is only for an emergency, only if we have to evacuate the ISS. We’re always looking at what we can do to ensure the safety of the crew."A scenario in which the space station would need to be abandoned is unlikely but not impossible.
