MOSCOW, March 1, 2019 (Roscosmos PR) — The Roscosmos State Corporation and NASA reached a consensus on ensuring the safety of the crew and the International Space Station itself (ISS) during the automatic docking of the Dragon 2 spacecraft to the US station segment. The specialists of the Mission Control Center and the operational control group of the Russian segment of the ISS will also monitor the docking process according to the protocol, in which it is established that if the proximity mode deviates from the standard one, the docking attempt will be terminated.

Experts of Roscosmos and NASA, studying possible abnormal situations when docking American commercial ships directly to the ISS (bypassing the manipulator in the American segment), came to the conclusion that the implementation of some docking scenarios increases the risk for the station and crew. As a result of painstaking work, the specialists of Roscosmos and NASA have developed options for action to reduce this risk and agreed to conduct this type of docking.

At the same time, the parties also worked out the algorithm of actions during the automatic docking. So, four hatches in the American segment where the American ship will be docked will be closed. In the event of an emergency, the crew will switch first to the Russian segment of the ISS, and then to the Soyuz MS-11 spacecraft.
