Abstract [en]

Human interplanetary flights have been widely considered as an unconditional priority towards the development of the astronautics for several decades now. Nevertheless, at the moment there are no certainly available technologies that can safely and effectively bring humans back to the Moon and conquer more distant objects in the solar system. This thesis is dedicated to the case of future expeditions to Mars. An extensive list of problems and critical considerations for this kind of missions includes: long time life condition maintaining; space radiation protection; microgravity effects minimization; capability of abort options and failure risk minimization. There are a number of concepts and approaches for Human Mars mission design. Each of them under favorable conditions might allow overcoming the existing barriers. The nuclear electric propulsion concept and more specifically a VASIMR engine are examined in details in order to estimate their real potential. The attractive from many points of view VASIMR engine proposition was evaluated as currently unrealistic due to several serious technical challenges including a requirement in developing a new space nucleargenerator with high power-to-weight ratio.
