Abstract Issue 1, 2016.

In this paper a combined heating-depressurization process for mining water from the regolith  of Mars is proposed and its feasibility discussed. It is shown that for water content in the regolith \leq 4wt%  as found in latitudes between -45^0 and 45^0 a combined heating-depressurization process offers better energy usage performance, with savings up to 40% possible. Utilizing a simplified geometrical model, an analytical expression for the performance of such combined processes in comparison with traditional heating is derived.

This paper considers the use of hematite for in-situ rocket fuel production on Mars. Hematite is so ubiquitous on Mars that it gives the red planet its color and, indirectly, its name. In the process proposed here, by exploiting the low atmospheric pressure on Mars, hematite offers the possibility of eliminating the electrolytic steps associated with current in-situ resource utilization schemes. In the proposed process, hematite (Fe_{2}O_{3}) from the rich deposits found on Mars (e.g. at Terra Meridiani) is reduced to magnetite (Fe_{2}O_{3}) which is used in a two-step thermochemical cycle for splitting water and CO_{2}, resulting in the production of H_{2} and O_{2}.

Abstract Issue 4, 2015

Article #1. Here is proposed scheme solution for construction of heat and solar radiation protection probes in the near-solar space, based on the previously proposed action principle of “electric solar sail”. In compare with conventional heat shields, proposed option provides better protection from the effects of solar ionic wind.

Abstract Issue 2, 2015

This article discusses the kinetic jet engine mode of application for cargo output to the earth orbit. Spacecraft acceleration is carried out by the use of impulse and kinetic energy of the special guided probes. These probes are ejected from the moon surface by means of throwers and move toward the Earth. The probes’ velocity increases under the Earth’s gravity. As a result, the group of high-speed probes is formed in the near-Earth space, and they can be used for cargo output into the earth orbit, using the kinetic jet engine.

Abstract Issue 1, 2015

The article discusses the construction of permanent structures on the lunar surface with the using of local building materials. For this purpose, local materials and design features of these materials are studied without consideration of ultrafine phase of such materials. It is believed that the Moon exists only in local magnetosphere. The areas of building structures are craters, which can play the role of screen at the time of solar activity thanks to the morphology of the inner surface.
