Interview with Dr. Oleg Atkov [interview by Winston Huff].

Abstract

Last summer International Space University (ISU) was held in Huntsville, Alabama. Leading international space experts came to take part in the activities. Dr. Oleg Atkov, a Russian cardiologist who was also a cosmonaut for eight months in 1984, has extensive experience in cardiovascular medicine and first-hand experience in issues of life support, making him a valuable resource. He also serves on the Journal's Advisory Board. Winston Huff took advantage of the unique opportunity of having Valery Aksamentov, Paul Wieland, and Dr. Atkov together in Huntsville to conduct a general discussion of issues important to those studying life support. Dr. Valery Aksamentov was involved for many years in the development of the Russian life support systems. Dr. Aksamentov now leads the only university program specializing in life support at the University of Alabama in Huntsville. His command of both languages and his technical knowledge were critical to the success of this discussion. Paul Wieland from NASA Marshall Space Flight Center is involved with the development of the life support systems for the space station. He and Dr. Aksamentov are topic coordinators for the Journal. The following interview was conducted at the University of Alabama in Huntsville on August 16, 1993.

Creation of biological module for self-regulating ecological system by the way of polymerization of composite materials in free space.

The large-size frame of space ship and space station can be created with the use of the technology of the polymerization of fiber-filled composites and a liquid reactionable matrix applied in free space or on the other space body when the space ship or space station will be used during a long period of time. For the polymerization of the station frame the fabric impregnated with a long-life polymer matrix (prepreg) is prepared in terrestrial conditions and, after folding, can be shipped in a compact container to orbit and kept folded on board the station. In due time the prepreg is carried out into free space and unfolded. Then a reaction of matrix polymerization starts. After reaction of polymerization the durable frame is ready for exploitation. After that, the frame can be filled out with air, the apparatus and life support systems. The technology can be used for creation of biological frame as element of self regulating ecological system, and for creation of technological frame which can be used for a production of new materials on Earth orbit in microgravity conditions and on other space bodies (Mars, Moon, asteroids) for unique high price mineral extraction. Based on such technology a future space base on Earth orbit with volume of 10(6) m3 and a crew of 100 astronauts is considered.

How we will go to Mars.

This article studies the efficiency of ejecting waste generated by the life support system (LSS) of a manned spacecraft to reduce initial mass on low earth orbit. The spacecraft is used for a long-duration interplanetary mission and is equipped with either a chemical or a nuclear-thermal propulsion system. For this study we simulate an optimal control problem for a given spacecraft maneuver. An impulsive approximation of the optimal interplanetary spacecraft trajectory is assumed, which allows us to reduce the general optimal control problem to hierarchic structure of 'outer' and 'inner' subproblems. This structure is analyzed using the Pontryagin's Maximum principle. Numerical results, illustrating the efficiency of waste ejection are shown for typical Earth-Mars transfer trajectories. This results confirm in theory that using a waste ejection system makes an early manned Mars mission possible without having to design and build new, advanced biological LSS.
