I seem to recall previous rovers were expected to have a limited life span due to dust build up on the solar panels but this never happened. Which is why the older rovers are still going, or at least went for a lot longer than expected.
Not sure about that, think the Curiosity panels are down to about 23% of clean panel power because of the dust, with no easy fix in sight..Future martians may need a whisk broom as their national emblem>

Curiosity is powered by isotope battery, no solar cells!

It might be, but you will have to wait until they build a hotel so you can isolate for 14 days upon arrival.

You can use a Martian license in the UK, but not a UK license on Mars.
Thats the way the #MARSBARS agreement was negotiated, but good news. Itís a soft border, just donít order oysters.

I'd posted a thread about this helicopter back in August 2019 but there wasn't any discussion on it. Here's a great video with more details on the helicopter:

According to the video filmed at NASA and linked in post #27 it has solar cells and a rechargeable battery. The solar cells are in the small panel above the blades. A one day charge fully charges the battery and allows a 90 second (I think it was) flight.

I don't think Atomic batteries are used very often because of the concern of the results of them falling back to Earth in the event of some failure.

I referred to post#21: Curiosity is the first rover, powered by isotope battery. Inguenity, the helicopter transported with rover Persevance, ( also with isotope battery ) is powered by solar cells.

And of course the Perseverance rover is powered by heat from Plutonium radioactive decay; I wonder how long it will operate?
