Description
Technical Field
The invention relates to a chemical actuating device and a stripping method suitable for breaking and stripping substances on the surface of a weak-attraction celestial body, and belongs to the technical field of deep space exploration.

In the process of deep space exploration, the detection target of the extraterrestrial celestial body has been turned to 'tracing the life origin, perfecting celestial body recognition and building future families'. The celestial body is an important carrier for human to know the evolution of the solar system origin, carries rich scientific information, contains rich noble metals and rare elements, has great utilization value, and has important scientific and engineering significance for detecting the celestial body.
Most of the surfaces (or part of the surfaces) of the celestial bodies are stored with a surface soil layer, and the formed surface soil layer is mainly formed by 'space weathering', including celestial body impact, solar wind ion input, material sputtering, micro meteorite bombardment and the like, so that a large amount of fragments and sand grains with different sizes and shapes are generated after the original materials of the celestial bodies are broken. In addition, solar irradiation, solar wind and space ions can generate electrostatic fields in the space of the surface of the celestial body, so that particles with smaller diameters generate a suspension layer, and the particles are gradually deposited to form soil under the effect of profit. The surface soil, scraps, gravel and the like of the surface of the celestial body are all the operation targets of the sampling task. The characteristics of the celestial body are complex, larger uncertainty exists, and the sampler has the environmental characteristics of weak attraction, low surface temperature, high vacuum and the like, so the sampler has low reaction force and does not depend on the operation capability of fixing the attaching gesture; the method is suitable for harsh working environments such as vacuum, low temperature, space irradiation and the like; meanwhile, multifunctional integration is needed to realize light design and meet the requirements of space mechanisms. At present, the extra-earth star soil sampling execution mechanism is based on the traditional mechanical operation principle, is difficult to adapt to the particularity of the small celestial body sampling task, and needs to design a novel sampling execution mechanism to adapt to the requirement of the subsequent task.
In addition, the space wind bloom effect of the celestial body subsurface layers such as the principal zone comet is weaker than that of the surface layers, so that the original state scientific information is easier to maintain, and the method has specific scientific detection value. Then, due to the characteristics of the weak attraction high vacuum environment of the small celestial body, the detector is difficult to attach and the large-force carrier is difficult to operate, and the surface layer is opened by adopting a high-efficiency and reliable surface substance stripping means, so that conditions are provided for detecting subsurface substances, and pollutants cannot be introduced to destroy original substance components of stars. At present, no effective technical means is available for achieving the above-mentioned objects.
