2018年11月26日，火星洞察号着陆器成功着陆，从这颗红色星球平坦的赤道极乐世界平原传回了首张图像。利用地震调查、大地测量学和热传输来探索火星内部的历史任务已经运行了1400多个火星日或火星日。在此期间，洞察号探测到1300多次火星地震，并记录了震动火星的流星体撞击的数据，观察地震波的传播方式，以了解火星内部。对收集到的数据档案进行分析，预计将在几十年内产生新的发现。但“洞察号”的最后一次操作任务可能离我们不远了。从今年早些时候拍摄的这张自拍中可以看出原因，照片上的甲板和两米宽的大太阳能电池板上布满了灰尘。在火星风的推动下，尘埃不断积聚，大大减少了洞察号太阳能电池板产生的能量。

The Mars InSight lander returned its first image from the Red Planet's flat, equatorial Elysium Planitia after a successful touchdown on November 26, 2018. The history making mission to explore the martian Interior using Seismic investigations, geodesy, and heat transport has been operating for over 1,400 martian days or sols. In that time the InSight mission has detected more than 1,300 marsquakes and recorded data from Mars-shaking meteoroid impacts, observing how the seismic waves travel to provide a glimpse inside Mars. Analyzing the archive of data collected is expected to yield discoveries for decades. But InSight's final operational sol is likely not far off. The reason is evident in this selfie recorded earlier this year showing its deck and large, 2-meter-wide solar panels covered with dust. Kicked up by martian winds the dust continues to accumulate and drastically reduce the power that can be generated by InSight's solar panels.
