The ISS-64 crews have completed preflight examinations taking several tests. Roscosmos cosmonaut Sergey Ryzhikov and his crew performed Soyuz MS spacecraft approach to the Rassvet Mini-Research Module 1 of the International Space Station after a two-orbit rendezvous followed by the docking and emergency descent back to Earth.
At first, during the injection ‘Favory’ (crew callsign) detected oxygen line leak with oxygen leaking inside the descent module, as well as automatics and atmosphere purification main ventilator unit failure. This was followed by the docking and orientation engines pressure indicators failure during the fly-around and berthing. In addition, Sergey Ryzhikov, Sergey Kud-Sverchkov and Kathleen Rubins faced an inextinguishable fire in the descent module. In conclusion, engine failure occurred while performing descent maneuver during an emergency descent to Earth.
The backup crew taking the exam on the Russian ISS segment faced FM transmitter failure. After coping with the problem, malfunctioning of Vozdukh system was detected. Following the instructions in the onboard documentation, the crew eliminated the atmosphere purification system malfunctioning, as well as coped with the problems in the waste collection system. Finishing the training, Oleg Novitsky, Pyotr Dubrov and Mark Vande Hei identified ammonia discharge into the station atmosphere.
The International Space Station crew will isolate in the Russian segment of the station in order to search the air leak. The crew will routinely perform all the scheduled works and is in absolutely no danger.
The crews successfully completed the training skillfully coping with all the malfunctions.
