摘要

火星探路者号是第一个在火星表面运行的太阳能探测器。探路者由一个着陆器和一个小型、自主的六轮太阳能漫游车“旅居者”组成。探路者号宇宙飞船反映了NASA开发新技术以降低任务成本的新理念。“探路者号”上的材料粘附实验是为了测量太阳能电池阵列的退化，因为大气中的灰尘沉降，阻挡了太阳能电池阵列的光线，降低了太阳能电池阵列的输出功率。MAE的测量结果表明，尘埃以每天0.28%的速度稳定累积。该值与太阳能电池阵列的性能一致，太阳能电池阵列的功率以每天0.29%的估计速率下降。

Dust on Mars: Materials Adherence Experiment results from Mars Pathfinder

Mars Pathfinder is the first solar-powered probe to operate on the surface of Mars. Pathfinder consists of a lander and a small, autonomous, six-wheel solar-powered rover, "Sojourner". The Pathfinder spacecraft reflects NASA's new philosophy of exploiting new technologies to reduce mission cost. The Materials Adherence Experiment on Pathfinder was designed to measure the degradation of solar arrays due to dust settling out of the atmosphere and blocking light to the solar array, lowering the array power output. The MAE measurements indicate steady dust accumulation at a rate of about 0.28% per day. This value is consistent with the performance of the solar arrays, which have decreased in power at an estimated rate of 0.29% per day.
