Yet another illustration that
"On ground" planetary exploration / investigation is very, very difficult compared to remote analysis from
above.
And frankly I'm impressed the remote "from above" operations have the success rate they do given the difficulty of the task of getting there & deploying sensors, sending data back (without the worry of landing).
The amazing performance & longevity of the Mars rover craft seems to have led people to think the "on ground" task is far easier than it is.
(full disclosure - relative of mine worked for NASA & has lunar crater named after them)
