"The cosmonaut training program including 12-15 training types for the ROS will be developed based on the adopted cosmonaut training concept. The development of the program is expected to be complete by 2025," the press Gagarin Center press office said, adding that the Center already carries out scientific research on cosmonaut training for the Russian station, together with interested organizations.
