Abstract

Because of the high amount of dust in the Martian atmosphere, solar panels of landers and rovers on Mars get covered by dust in the course of their mission. This accumulation significantly decreases the available power over sols. During some missions, winds were able to blow the dust away. These ”dust cleaning events”, as they are called, were followed by an increase of the electrical current produced by the solar arrays. However, the Insight Lander solar panels were never cleaned and the mission died of dust accumulation. In order to better predict the evolution of available power produced by solar panels in the Martian conditions, this paper proposes a model of dust accumulation in which the solar flux under the accumulated dust layer is computed taking into account a full radiative transfer in the atmosphere and in the dust layer accumulated on the panel. This work uses several missions observation data to validate this model.

火星车和着陆器太阳能电池板因灰尘沉积而导致功率衰减

由于火星大气中含有大量灰尘，火星上的着陆器和漫游车的太阳能电池板在执行任务的过程中会被灰尘覆盖。这些灰尘的积累大大降低了太阳能电池板的可用功率。在某些任务中，风能够将灰尘吹走。这些所谓的 "灰尘清理事件 "之后，太阳能电池阵列产生的电流会增加。然而，"洞察号 "着陆器的太阳能电池板从未清洗过，这次任务也因灰尘堆积而失败。为了更好地预测太阳能电池板在火星条件下产生的可用功率的变化，本文提出了一个灰尘积聚模型，在该模型中，计算了积聚灰尘层下的太阳通量，并考虑了大气层和电池板上积聚的灰尘层中的完全辐射传递。这项工作利用几个任务的观测数据来验证这一模型。
