月痕寿命研究

Research on Life Span of Lunar Footprint

针对月痕资源开发的可行性情况,研究了月痕寿命的问题。首先分析了自然和人为因素对月痕的影响,自然因素包括微小流星体的撞击和静电浮扬月尘的沉积,人为因素主要是飞行器着陆与起飞时发动机喷射的燃气羽流,得到了各因素对月痕寿命的影响程度。然后通过开展沙痕试验,为月痕寿命估算提供事实依据。最后结合各因素对月痕寿命的影响程度和沙痕试验的结果,对月痕寿命进行了估算。估算结果表明,月痕在不受人为破坏的情况下,寿命至少可达数十万年。因此,月痕完全可作为一种资源用于开发,具有良好的商业前景。

The life span of lunar footprint was studied to evaluated the feasibility of lunar footprint resource utilization.First,the influences of natural and anthropogenic factors on lunar footprint were analyzed.The Natural factors include the micrometeorite impacts and the deposition of electrostatic floating lunar dust,while anthropogenic factor is mainly the engine plume during the landing or launch of spacecraft.The degree of influence on the life span of lunar footprint by each factor was obtained.Then,the experiment of sand footprint was conducted to provide factual basis for the estimation of lunar footprint life span.In the end,combining the degree of influence on the life span of lunar footprint by each factor and the result of sand footprint experiment,the life span of lunar footprint was estimated.The estimation results showed that the life span of the lunar footprint could be as long as several hundred thousand years without anthropogenic damage.So lunar footprint as a resource can be exploited and with a promising business aspect.
