A coolant leak from the Russian Soyuz spacecraft currently docked to the International Space Station may mean the vessel is damaged beyond repair, according to one expert. The malfunction occurs at a critical time; if the Soyuz capsule is indeed inoperable, the ISS would lack the capacity to evacuate all of the astronauts on board for the first time in the station’s history. Seven astronauts are currently aboard the ISS, but with the Soyuz damaged, there would only be sufficient capacity to evacuate four in the event of an emergency.
