The first unmanned rover landed on the lunar surface in November 1970. Since then, more than a dozen vehicles of this class have operated on the Moon and other celestial bodies, yet none of them has been equipped with a tracked (continuous-belt) suspension, chiefly because of its mass, which significantly increases launch cost. In parallel, scientific instrumentation continues to be miniaturised, as exemplified by the growing adoption of CubeSat-class platforms. This paper presents the prototype of the #COSMOBOSS ...

A key environmental and technological problem for coal-fired generation in the Russian Federation is the overfilling of existing ash disposal sites. The total volume of accumulated solid coal combustion waste has reached 2 billion tons. It is important to emphasize that this figure reflects only the accumulated "legacy burden" and is not a fixed value: the industry generates about 20 million tons of new waste annually. Consequently, the actual mass of this waste requiring disposal or processing is steadily increas...

Combustible dusts are presented in industry as a finished products or process intermediates created voluntarily by milling or involuntarily by abraison of larger sized solid. Spontaneous combustion is a phenomenon that occurs by self-heating, increase in temperature due to exothermic internal reactions, followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition. The oxidation of combustible powders occurs when they react with air oxygen, producing carbon dio...
