The main phenomena of space crews' communication as a rationale for the modification of mission control communicative style.

The article describes the phenomena of communication between space crews and the Mission Control Center studied within the framework of the "Content" space experiment. The experiment was conducted with participation of Russian cosmonauts during ISS-43/44 - ISS-54/55 missions, and a specially developed method of content analysis of crew-to-ground communication was used. It was shown, for instance, that the structure of communication varied significantly depending on the degree of the cosmonauts' workload and stress-related psychological tension.

Effects of isolation, crowding, and different psychological countermeasures on crew behavior and performance.

Studies conducted by I. Altman in the 1960-70s revealed the increase in the individual stress level under isolation and confinement. Altman introduced the term "privacy" as a desired level of personal space that humans need to feel psychologically comfortable.

Applications of methods of psychological support developed for astronauts for use in medical settings.

Over the past 40 years, psychological support (PS) for cosmonauts and astronauts has remained an important part of the regular biomedical provision of space crews during extended orbital flights. It includes well-developed principles and a set of methods that have proven its effectiveness for the maintenance of behavioral health under extreme conditions of space flight. The main principle of PS in flight is to restore the usual sensory input to compensate for the monotony and lack of external stimuli as a result of a long stay under isolation and confinement.

Assessment of the Psychophysiological State of Female Operators Under Simulated Microgravity.

The article describes methods of non-verbal speech characteristics analysis used to determine psychophysiological state of female subjects under simulated microgravity conditions ("dry" immersion, DI), as well as the results of the study. A number of indicators of the acute period of adaptation to microgravity conditions was described. The acute adaptation period in female subjects began earlier (evening of the 1st day of DI) and ended faster than in male ones in previous studies (2nd day of DI).

External Communication of Autonomous Crews Under Simulation of Interplanetary Missions.

Two experiments, with 17-day and 120-day isolation, were carried out within the frame of the Scientific International Research in Unique Terrestrial Station (SIRIUS) international project at the Institute of Biomedical Problems (Moscow, Russia). Manifestations of the "detachment" phenomenon in the crew - mission control center (MCC) communication previously identified in the Mars-500 project were confirmed in this study. As in the Mars-500 experiment, in the SIRIUS-19, the landing simulation in the halfway of isolation caused a temporary increase of crew communication with MCC.

Prospects for Psychological Support in Interplanetary Expeditions.

The article gives an overview of Russian experience in psychological support for orbital space flights. It describes procedures that currently exist and may possibly be used in upcoming manned interplanetary flights. The article also considers psychological unfavorable factors of autonomous interplanetary flights, as well as countermeasures, including promising methods of psychological support.

Style Features in Communication of the Crews With Mission Control.

In "Content," an International Space Station (ISS) Russian segment space experiment, features of communication between the cosmonauts and the Mission Control Center (MCC) were studied using content analysis. The method is based on the concept of stress copings by Lazarus and Folkman. Differences found in the communication of cosmonauts led to assumptions about the existence of individual communication styles in routine communication between the cosmonauts and the MCC.
