Application of a Multi-User Virtual Environment for Simulating Operations for New Projects of Manned Space Flights.

The paper deals with the problem of obtaining professional experience by cosmonauts under the earth conditions in the interests of promising projects of manned space flights using a multi-user virtual environment as an online tool providing communication and control of an operational interaction between a cosmonaut and a scientific-pedagogical team of experts in various related fields when developing scenarios for the crew's activities under conditions of high uncertainty of the initial data in future projects.

Standardization of Equipment and Methods of Medical Control in Manned Space Flights and Issues of Telemedicine

Since April 1961, all manned space flights have been accompanied by medical control ensuring flight safety. Medical control in space flight has a technological and medical methodology that allows, at a distance from medical specialists, to make an adequate medical decision for the current situation. This work would be impossible if there were no measures taken to unify and standardize equipment and techniques. Telemedicine technologies developed on the basis of flight medical control. The origin of the word telemedicine comes from the expression «telemetric medical information», adopted in space technology. The issues of mutual development and mutual enrichment, standardization of methods and equipment of two areas of medicine, medical control in extreme situations and general telemedicine are considered in this article.

Modeling the influence of heavy ion beams on neurogenesis and functioning of hippocampal neural networks

Radiation-induced impairment of hippocampal neurogenesis is one of serious factors associated with cognitive detriments after radiation therapy of brain cancers and realization of long-term manned space flights. The goal of this study is to develop a mathematical model describing radiation-induced changes in cellular populations participating in neurogenesis and how these alterations worsen the processing of information by hippocampus. Modeling results have demonstrated that heavy ions may cause non-reversible suppression of neurogenesis, which is followed by failure of pattern encoding and retrieval by hippocampal neural networks.
