Russia launches rescue ship to ISS after leaks
- Russian Soyuz capsule will bring home three astronauts whose return vehicle was damaged by a tiny meteoroid
- The damaged supply ship was cut loose over the weekend, burning up in the atmosphere
Russia launched a rescue ship on Friday for two cosmonauts and a Nasa astronaut whose original ride home sprang a dangerous leak while parked at the International Space Station.
The new, empty Soyuz capsule should arrive at the orbiting lab on Sunday.
The capsule leak in December was blamed on a micrometeorite that punctured an external radiator, draining it of coolant. The same thing appeared to happen again earlier this month, this time on a docked Russian cargo ship. Camera views showed a small hole in each spacecraft.
The Russian Space Agency delayed the launch of the replacement Soyuz, looking for any manufacturing defects. No issues were found, and the agency proceeded with Friday’s predawn launch from Kazakhstan of the capsule with bundles of supplies strapped into the three seats.
Given the urgent need for this capsule, two top Nasa officials travelled from the US to observe the launch in person.
Officials had determined it was too risky to bring Nasa’s Frank Rubio and Russia’s Sergey Prokopyev and Dmitri Petelin back in their damaged Soyuz next month as originally planned. With no coolant, the cabin temperature would spike during the trip back to Earth, potentially damaging computers and other equipment, and exposing the suited-up crew to excessive heat.
Until the new Soyuz pulls up, emergency plans call for Rubio to switch to a SpaceX crew capsule that’s docked at the space station. Prokopyev and Petelin remain assigned to their damaged Soyuz in the unlikely need for a fast getaway.
