Why do mars robots die becouse of dust on solar panels?

248 views

For me it seems strange that a 200Mlj Mars robot (like Insight,etc) meet the end of life becouse of dust on solar panels. Why they aren’t equiped with some kind of vibration mechanism or windshield wiper-similar thech to deal with a problem? This seems to me like WTF?

Given a finite amount of money, development time, and weight… consider a trade-off between “adding a self dusting mechanism” vs. “add another useful sensor”.
