Frost (above) covers the calibration target on Opportunity which is usually black (below)
The BBC article (http://news.bbc.co.uk/1/hi/sci/tech/4094437.stm)

This looks more like looking through night vision goggles than frost to me. Considering the background, which is the ground itself, is almost completely black in the "frost" pic.

srr if i am a little unobservent, but the pictures you've shown, what are they suppose to represent? Please give a very simple explanation I don't know much about this though I read the article which I though was very interesting. It's cool how there is water formation on mars and seasons. Space is a very interesting subject and the study of alien's two... anyways that's awsome :2thumbs:

What you are seeing in the pictures is the calibration device for the rovers on Mars.

It may have been taken with a thermal camera. Im not an expert on that sort of stuff, so i don't really know. Pretty cool how there is actually clouds and seasons on mars. It is so much like our planet; atmosphere, plenty of gravity, seasons, weather, 25 hour day (almost the same). It just goes to show how we could land man on mars one day.

Having grown up half my life seeing frost in all its forms, the last thing I would think this was is frost. I go with the thermal vision explanation.

Now I can't say too much because I have not been following too closely, but if there is water vapour in the atmosphere to a point that stuff would be covered in frost, then why are they so unsure if there is water on Mars? Unless it isn't water frost as we know it, and it is some other gas/vapour that has accumulated, but I'm still going with the camera as the explanation.

They arent unsure if theres water on mars. Most scientist are convinced now there is or was water on mars.. even nasa agrees there was and might still be

Yeh RWF i thought the exact same thing, its like inverting the black and white colors like an negative

That's my point. You can't have frost without water vapour. So if they are so sure this is frost, then they shoul know that water exists. But, in order to have water vapour/frost, you need water to evaporate, and condense, hence there shouldn't be any question about water on Mars. Unless, it is carbon dioxide, ie dry ice.

This was found by the Opportunity Rover on Mars. Scientists are saying it is a meteorite, but like the above pic with the "frost" it looks as if it were taken in night vision. The "meteorite" looks like it was photoshopped in to me.

What the heck? Out of all people, Nasa. Why is the quality of the photo so cheap? That meteorite does look fake to me.

Sure looks as if it's been pasted in...

Did you notice how ROUND those little pieces of rock are, around the meteorite? Really looks like wear from either wind or water..

true true you know it could be proving that it is a fake or that there's water on mars which was once before melted... well I think it's faked it looks so artificial
