Dust storm on Mars is threatening the Opportunity rover.

Analyzing pictures for fun is fun. I like having a little but of insight on what is going on in the world on another world.

This one was taken yesterday by Curiosity.

For comparison, this one was taken 20 'sols' earlier

The signal clearly has a little bit of difficulty punching through the dust storm.

That signal is almost certainly going through a ton of ECC (error correcting codes) and is either going through in its entirety or not.  I'd bet that's sand left on the lens.

Wouldn't it be out of focus if it was on the lens?

Possibly just sensor noise due to the low light level.

They are out of focus.  Or at least they probably are.   It's really hard to tell, sand is quite small.   The rest of the photo is in focus, as expected.   It's only if you try to focus on the sand on the lens will the rest of the photo go out of focus, if the f stop is low enough (low in this case is below 50).   A high enough f stop, and the entire pic would be in focus, sand and all.

While Opportunity needs to hunker down and weather the storm, Curiosity keeps going.

I.e. while Opportunity uses an auto-balanced self-sustaining fuel-independent fusion reactor in 1.5 AU away via a semiconductor remote receiver, Curiosity spends the pieces of an artificial fission material.

I think the grainyness might be causes because of a solar storm rather than the dust. This was taken a few hours ago.

So the dust has either settled (wich i kind of doubt) or the sun is blasting the thing with radiation, and that is what causes all the dots. Apparently the dust storm is at its peak right now, according to some news articles.

There is also the chance the rear camera has become bad.

We can clearly see some dust particles that have landed on the camera.

There are winds on Mars, so maybe the rover can have its solar panels cleaned. Maybe, just maybe.

Would it be possible for a rover to use an air compressor to blow dust off the solar panels instead of waiting for a random wind?  Would an air compressor work in such a thin atmosphere?

maybe, but air compressors take up space and tend to be heavy, also they wouldnt help in this case because the dust blocks out most of the sunlight
