‘My power’s low’: NASA’s Insight Mars lander prepares to sign off
I&#x27;m confused on why the end state for all these rovers is to loose power because of dust on the solar cells.  They did such a good job engineering these things to survive the trip and the conditions in general, but they can&#x27;t give them &quot;windshield wipers for dust&quot;?  Seems like with that minor upgrade they could have much longer lifespan.<p>Can someone enlighten me?
