## 4 Materials and Methods  
The state of knowledge on the effective search for space resources presented in the work is the result of several years of literature studies conducted by the Polish space mining startup Solar System Resources Corporation Sp. z o. o. in cooperation with scientists from Polish and foreign research units. It is also part of the extensive know-how acquired by this company. The information bottleneck of all space mining projects to date is the lack of accurate industrial data, but also the lack of ordering and synthesizing the already available scientific data. Another is the lack of cheap transportation in Cis-Lunar space, but that could change the SpaceX Starship and other future competing solutions. The business world makes rational decisions based on accurate data and information about the current or future market. Unfortunately, the data collected so far about the Moon and other objects in the solar system has served scientific rather than industrial purposes. Only now are we observing plans for the first missions more focused on obtaining industrial data--an example here is the Polish Moon Mission [61], which is planned by the Polish Space Agency (POLSA), which will use the MIRORES instrument, the aim of which is to select areas on the Moon with the highest resources potential, especially in terms of metals, sulfur, and helium-3 [62]. The first results from the Korean Pathfinder Lunar Orbiter (KPLO) mission should be published soon [63]. The analysis conducted leads to the conclusion that the most promising areas on the Moon in terms of raw materials are craters and some of the cold traps located inside them. Are there places on the Moon with a higher concentration of raw materials that could be more profitable to exploit? The answer to this question is positive. For example, the Cabeus crater has a diameter of 100 km, an area of 7815 km\({}^{2}\), and a depth of 4 km. It will not be an area easily accessible on the Moon, and its operational depth is large: over 6 times greater than New York City (USA) and 24 times greater than Krakow (Poland). The permanently shaded areas in this crater cover an area of 315 km\({}^{2}\) or approximately 40% of the land area of New York City (USA). Given the limitations of rovers in terms of power and mobility, this is a huge area to explore, which creates a high risk of mission failure. It would therefore be worth finding smaller cold traps that would be rich in resources. The answer may be the so-called cold microtraps. Cold micro traps are basically the same as regular cold traps, but their sizes are much smaller, ranging from a few centimeters (even such small craters may have permanently shaded areas) to several kilometers. They are also much shallower, which means that a rover or mining dump truck will be able to easily enter/exit such an area, and therefore it will be easier to manage the limited reserves of electricity in these devices. Cold microtraps may also contain significant resources of valuable raw materials. On the Moon, a bigger crater does not always mean better. If the deposits are formed as a result of the mechanism described in the publication [39], the high edges of large craters may impede the movement of charged particles so that they can reach the cold trap and be depositedthere, which should not be the case in the case of cold microtraps and theoretically should be easier deposits form in them. At Solar System Resources Corporation Sp. z o. o., at the end of the second quarter of 2022, a project was launched to develop a commercial interactive map of the Moon, which would be a repository of data on deposits and contain information useful for teams designing commercial and scientific lunar missions. The reports contained in this repository are intended to respond to the problems described in point 3 and other potential problems, so as to increase the success of missions--especially commercial missions.
