Talk about excellence in engineering. These rovers were not expected to last near this long. And at least one is still chugging away after a DECADE! Wow.
It is amazing.
My son works at NASA. His particular satellite mission is many years past its budgeted lifespan.
His previous mission is a solar observatory that launched the month he was born and is still operational.
Maybe excellence in engineering, but I can see a pretty glaring design flaw. Who designed the solar panels without a wiper, fan, something to clean off dust?
This would still be working if the solar panels were cleaned.
Maybe it’ll rain soon.....................
