The rationality of regional land planning needs to be evaluated through intelligent technology and continuously optimized. At present, most land planning is temporarily adjusted according to actual ...needs, so it does not have real-time dynamics. In order to improve the rationality of regional land planning, based on BP neural network, this study combined the spatial mining technology to construct a regional land planning model, and used BP neural network and SVM technology to establish a relationship model between the impact factor value and distance scale factor. Moreover, based on the gray system theory, this study uses the gray correlation model to measure the coupling degree between industrial structure and land use, and analyzes the correlation between various factors. In addition, the artificial neural network after learning and testing can be used for dynamic simulation calculations. The research results show that this algorithm has some practical effects.

Against the background of rapid advances in space technology and better understanding of the composition of celestial bodies, the utilisation of space resources has become an increasingly important ...topic; however, the lack of a comprehensive legal framework and the consequent legal uncertainty surrounding legality and conditions under which space resources can be utilised represent a significant barrier for private investors. To be precise, outer space is not unregulated. There are norms of customary international law applicable to activities in outer space, and fundamental legal principles have been enshrined in the Outer Space Treaty. What is more, the Moon Agreement declared space resources the common heritage of mankind and envisages the establishment of an international legal regime; however, the Moon Agreement – the only international treaty explicitly addressing space mining – has been ratified/acceded to by only 18 states, and legal principles enshrined in the Outer Space Treaty are too vague to provide private investors with the regulatory certainty they need. As a result of the lack of progress on legally binding instruments within traditional fora, especially the UN COPUOS, several states decided to address legal certainty unilaterally – via national law. National legislators should take into consideration that national space mining laws are to be applied in an area that is open for access and use to all, an area recognised as res communis omnium. This article analyses regimes governing the utilisation of space resources and aims to identify practical implications for national legislators and diplomats.

The global climate crisis forces the search for new ecological sources of energy and mining methods. Space mining can solve those problems, but, first, wide geological surveying space missions using ...drilling methods are necessary. Additionally, drilling methods will be important in geological, life searching, geoengineering, and many other studies of extraterrestrial objects. Space is becoming a new area of possible drilling applications. Designing future space drilling missions requires adapting drilling technologies, not only to the conditions of the space environment, but also to the economic and technological realities of the space industry. The possibility of constructing low mass coring devices with energy consumption below 100 W was investigated in this paper. Minimization of energy consumption and mass of a coring is essential for the device to be used in space missions, when lander instruments supplied by low power electric battery are expected to work reliably and the launch cost (depending of mass) at an economically acceptable level. Some similar devices investigated for the future space missions are known from papers listed in the references. To answer whether or not it is possible to build such devices, the authors performed initial drillability tests. The obtained results are presented in this paper.

The article uses the Lunar QuickMap tool to analyze and select five highly promising cold microtraps on the Moon in terms of the size of the deposits they contain and their accessibility with the use ...of rovers and other wheeled vehicles. Since the thickness of the layer containing raw materials is subject to high uncertainty, three arbitrary scenarios for the value of this parameter were assumed: pessimistic (1 cm), nominal (5 cm), and optimistic (1 m). For the analyzed sites, a preliminary market valuation of the raw materials contained therein will be obtained at USD 74 billion; USD 370 billion; USD 7403 billion for the assumed pessimistic, normal, and optimistic scenarios, respectively. The article presents a business and technological perspective on the issue of space mining on the Moon. It is also a selected synthesis of the state of knowledge about space mining on the Moon.
The concept of sustainability is widely acknowledged as a political guideline. Economic, ecological, social and cultural aspects of sustainability are already under discussion. Current space mining ...efforts demand that the discussion become a broader one about ‘planetary sustainability’, including the space surrounding Earth. To date, planetary sustainability has mainly been used with reference to Earth only and I will extend it here, elaborating on a similar NASA initiative. This article (1) sketches the contemporary economic–political initiatives which call for a special reflection of Earth's location in space, and then (2) discusses the meaning of the concept of sustainability in this context. Next, (3) I relate the discussion to the issue of planetary and environmental protection, before, (4) finally, presenting a philosophical and theological perspective that seems particularly able to broach the issue of the multiple dimensions of sustainability in this context. This is the concept of constructive-critical realism. My overview of the topic concludes with (5) a summarizing outlook.

In our immediate solar neighbourhood in space is the Sun and then in order Mercury, Venus, Earth (and its satellite the Moon), Mars (and its satellites Fobos and Deimos) and then a series of ...asteroids. This is the arena for a growing international effort, both co-operative and competitive, not only in exploration but also in increasingly commercial terms. A race to exploit resources to be found in space, not least in the asteroid belt, is developing. These space activities have both political and economic impact on Earth. Greater collaboration is essential in future, especially to deal with potential dangers from space.

The discrete element method (DEM) is a numerical technique used in many areas of modern science to describe the behavior of bulk materials. Terramechanics of planetary soil analogs for
resource ...utilization activities is a research field where the use of DEM appears to be beneficial. Indeed, the close-to-physics modeling approach of DEM allows the researcher to gain much insight into the mechanical behavior of the regolith when it interacts with external devices in conditions that are hard to test experimentally. Nevertheless, DEM models are very difficult to calibrate due to their high complexity. In this paper, we study the influence of fundamental model parameters on specific simulation outcomes. We provide qualitative and quantitative assessments of the influence of DEM model parameters on the simulated repose angle and computational time. These results help to understand the behavior of the numerical model and are useful in the model calibration process.
Celestial bodies like the Moon and asteroids contain materials and precious metals, which are valuable for human activity on Earth and beyond. Space mining has been mainly relegated to the realm of ...science fiction, and was not treated seriously by the international community. The private industry is starting to assemble towards space mining, and success on this front would have major impact on all nations. We present in this paper a review of current space mining ventures, and the international legislation, which could stand in their way - or aid them in their mission. Following that, we present the results of a role-playing simulation in which the role of several important nations was played by students of international relations. The results of the simulation are used as a basis for forecasting the potential initial responses of the nations of the world to a successful space mining operation in the future.
•The realization of space exploitation will disrupt world politics.•The simulation highlighted the political tensions and different interests.•Inclusive international process is needed to reach fast adaptation.•Creative mechanisms are needed to allow sharing of new global wealth.

There is currently a surge in interest from both private and government sectors in developing technology for mining asteroids and the moon (“space mining”). One of the key benefits highlighted by ...advocates of space mining is that it minimizes the usual problems associated with mining on earth in terms of pollution, environmental degradation, and encroachment on human habitats. Two studies—one conducted on a 27-nation sample (N = 4819), the other conducted in the U.S. (N = 607)—provide the first test of the assumed (but never studied) notion that space mining is more palatable to the public than terrestrial mining. Both studies indicate broad support for asteroid mining: levels of support were reliably above the mid-point, and much greater than for other forms of frontier mining such as mining the ocean floor, mining Antarctica, mining the Alaskan tundra, and lunar mining. Unlike terrestrial mining, community attitudes toward mining asteroids were largely non-ideological; support was not correlated with perceptions of ecological fragility, political ideology, or individualistic/hierarchical worldviews. In summary, the current studies suggest that mining companies have a “social license to operate” for mining asteroids, but less so for lunar mining.
The past couple of years have witnesses one of the most exciting, yet controversial, developments in the field of space law, namely the adoption of domestic laws authorizing the (private) ...appropriation and utilization of outer space resources. Even though the technology to effectively mine resources in outer space is still under development countries like the United States and Luxembourg have taken this legislative step as a mean to promote the growth of a domestic private space mining sector.
The enactment of national space resources utilization laws has generated extensive interest both within academic circles and official fora, such as the United Nations Committee on the Peaceful Uses of Outer Space (UNCOPUOS). In this context, several countries have expressed their opinion about these initiatives, by often criticizing their legality vis-à-vis international space law.
Despite this remarkable level of interest there is a country that throughout this process has maintained a low profile, namely China. Indeed, China has neither reacted to the US and Luxembourgish moves nor has officially commented on the lawfulness of domestic space mining laws. This conduct is particularly relevant not only in the light of the growing importance of the Chinese space program but also if one considers that China is the country most involved in the exploration and study of celestial bodies and their resources, particularly the Moon. For this reasons it would have been legitimate to expect China to have a more engaged behavior. However, China has acted otherwise.
It seems thus worth evaluating whether China should maintain this ‘wait and see’ approach or should instead switch towards a more assertive position, both internationally and domestically, especially one which includes the adoption of a space resources utilization act.
