Mars rover gets "cleaned" - but by what? Or who? :o

if the martians cleaned the thing, we can get martian DNA and make an army of unstoppable martian/human soldiers........ think of the possibilities.....

Bad idea...

If it was just dust couldn't it just be cleaned by wind?

I'm thinking when it was on the panels created some kinda static field, attracting dust n stuff, turning it off + wind n shit = clean.

Unlikley. Wind speeds would have to be roaring at insane speeds, like faster than a hurricane.

Air pressure on the surface of Mars is about 100 times less than Earth (average of 6 millibars). Wind is almost non-existant. The air pressure is so low in fact, that even though it's -60 degrees celsius (-80f) any water that might exist would boil away into the atmosphere.

That takes wind, and martian carwashes out of the equation.

Probably figured it would take more energy to wipe it then would give energy back. (use all that energy, just for dust to cover it before you get the energy back).

Doesn't Mars have huge sandstorms?

the sheer scale of martian dust (much much smaller than your typical Earth dust) makes it pretty much pointless to try to wipe, or even blow it off of your equipment (cue sexual inuendo).

Yes, huge ones, lasting months... Like max_cool said, martain dust is incredibly fine, if there was a manned mission to mars it would be a big problem, it would get through airlocks, into CO2 scrubbers, everywhere. Thats why it's so easy for these sandstorms to exist.

Here is something someone else said somewhere:

According to reports; winds seldom obtain 300 mph on Mars. However, since the Mars atmosphere is less than 1% that of earth, comprised of mostly CO2, you must divide your wind speed by at least a factor of 10 in order to get an equivalent wind speed on Earth, so if there is a 100 mph wind it will become like a 10 mph wind on earth. However, because there's absolutely no measurable moisture in that Mars atmosphere, thereby even lesser density is where a 15:1 ratio might actually become more correct, thus 150 Mars mph = 10 Earth mph and, a 100 mph wind would likely resemble 6.7 mph on Earth. In other words, you could easily stand up and walk into and about a 750 mph wind tunnel and, aerodynamic landing speeds would likely require 2000 mph as well as fatter aerodynamic wings spanning nearly a quarter mile across.
