translation.en: Now you say, Charles, you are really lying to us, and so on, but that's not true. We really believed they were going to last 90 days or 100 days, because they are solar powered, and Mars is a dusty planet, so we expected the dust would start accumulating on the surface, and after a while we wouldn't have enough power, you know, to keep them warm.
translation.zh: 现在你会说，查尔斯，你在瞎说， 事实恰恰相反。以前我们真的认为火星车 只能坚持90到100天，因为它们是太阳能驱动的， 火星是有尘土的星球，我们认为 尘土会在太阳能电池表面积累，过一段时间 我们就不会有足够的电能了，不能保持火星车存活。
