#天问一号##微博公开课# 【中国火星车的太阳能电池板在火星上落了尘土怎么办？】天问一号火星车总设计师贾阳介绍，我国的火星车太阳能板采用表面工程技术除尘法，这个技术的关键是超疏基结构，身边的汽车防尘玻璃、防尘贴膜等都是这个原理。类似下雨时荷叶上的水珠，遇风可以很容易滚落。此前美国机遇和勇气号都曾因为太阳能板被沙尘覆盖失去动力，后因为一场火星沙尘暴因祸得福。

[What to do with dust cover on solar panels of Mars rover]
Jia Yang, chief designer of the Tianwen No. 1 rover, introduced that Mars rover solar panels use surface engineering technology to remove dust. The key to this technology is super-lyophobic structure, the dust-proof glass and dust-proof film of automobiles around you are made based on this principle. Similar to the way that rain water droplets on lotus leaf can easily roll off in the wind. Earlier, the US Opportunity and Spirit rover had lost power because solar panels were covered by sand and dust, but later a Martian dust storm has became a blessing in disguise and blown off the dust. @空天追梦V
