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

251 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?

The dust isn’t just on the panels. It’s in the air. Massive duststorms on Mars can cover the entire planet and block out the Sun, and the rovers depend on solar power to keep their electronics warm enough to function.
