Description

Celestial body directional mining method based on space garbage recovery and cold welding protection for NHD Technical Field The invention relates to the technical field of aerospace mining and space garbage recycling, in particular to a control method for a general celestial body to directionally fall to a preset designated area, and especially relates to a system architecture method for synchronously realizing celestial body directional falling and space garbage recycling through the cooperative operation of three subsystems of Na, hi and Da. Background Along with the increasing frequency of spaceflight activities, the quantity of space garbage in a near-earth orbit is increased, which forms a serious threat to an on-orbit spacecraft, and meanwhile, planets, merles and other celestial bodies are rich in mineral resources such as rare metals and the like, so that the method has extremely high exploitation value. In the prior art, celestial body orbit control is mostly used for preventing from striking the earth (such as a NASA nuclear explosion deflection patent), space garbage cleaning and celestial body mining are usually carried out as independent tasks, and the cost is high and the efficiency is low. In addition, special ablation protection layers are needed when the meteorites reenter the atmosphere, so that the exploitation cost is further increased. How to synchronously realize the directional falling of celestial bodies and the recovery of space garbage with low cost and high efficiency and convert garbage into protection resources is a technical problem to be solved in the field. Disclosure of Invention The invention provides a control method for a general celestial body to directionally fall to a preset designated area, and aims to solve the problems of high celestial body mining and garbage recycling cost and high protection difficulty in the prior art. For convenience of description, the present method is hereinafter referred to as "NHD". Wherein Na represents a directional orbit control subsystem, hi represents a surface pretreatment and cold welding protection subsystem, da represents a space garbage collection and net body recovery subsystem, and the three are operated cooperatively according to the sequence of Na, hi and Da to jointly realize a complete technical scheme. The method takes generalized logic, adaptive execution and three-version grading as a core, has no limitation of celestial bodies (size/distance/material), target areas and force application devices to be controlled, only defines the core execution logic, integrates the integrated low-cost design of space garbage collection, space self-cooling welding, ablation sacrificial protection and grading antifriction according to needs according to double requirements of mineral exploitation and space garbage recovery, directly gathers the space garbage as a protective ablation layer, can be flexibly applied according to the material of the surface of the meteorite, realizes the joint fixation of the space garbage and the meteorite for the metal component-adaptive scene of the surface of the meteorite, forms a complete airtight protective shell similar to a 'solid shell' for self-cooling welding between the space garbage, fully wraps the inside to-be-exploited ore, does not need to be welded with the space garbage body, only realizes firm wrapping through the structure of the shell, not only completes the garbage cleaning, but also reduces the cost of the space protecting and screening and picking the space garbage. The key functional modules of the method comprise: 1. celestial body selection, namely selecting celestial bodies (such as merle, asteroid or interstellar fragments) which can be accurately observed and can be used for operation. In a preferred embodiment, the target is the earth-near orbit 5-20 meters of iron-nickel merle or silicate asteroid, containing high value mined minerals. 2. After the target area is determined, modeling and measuring the force application threshold value, the moment and the direction, covering the three versions of common measuring and measuring logic, namely 'remote guiding to the target area associated track redirection', 'direct redirection through the target area associated track'. Meanwhile, according to the current track of the target celestial body and a preset falling point (such as a Pacific unmanned area), the required speed increment, the force application point position and the force application direction are calculated reversely, so that the changed reentry track is ensured to be strictly directed to a preset safety area, and the risk of false falling is fundamentally avoided. For example, STK software can be used to calculate, accurately pre-judge the drop point or the butt point. 3. And pollution detection, namely drilling a celestial deep rock core, and confirming that no extra-ground microorganism pollution exists, thereby conforming to the international planet protection proto
