Well, we've known for a century that the "north polar hood" of clouds and haze forms every Martian spring and fall. But I'll tell you, I'm *really* pumped to see it floating overhead like the leaden lid of an overcast day. That really makes Mars a familiar-looking place, to me.

I just worry a bit about how much energy-delivering sunlight those clouds are blocking.

Probably not that much, in fact they could mostly be forward-scattering light in essence making the illumination more diffuse only.

It may just be an artifact of the animation, but it sure looks like there's a fallout streak visible under one of those clouds - look at each frame separately. Please someone convince me I am mistaken.

One could certainly infer fallout under these clouds. It's what LIDAR is telling us.

really cool animation! blink.gif
It's a pity it's no available in color.

I think it should also be possible to obtain a stereo anaglyph of clouds from a couple of this frame.

Another cool animation:

I guess it\'s due to the wind?

It\'s by ElkGroveDan (Post: http://www.unmannedspaceflight.com/index.p...t&p=126143)

How can I attach to this message same attachment of another message without saving it to my hard disk? huh.gif

EDIT:

Those are hot pixels in the detector. The sky is too bright at all times for SSI to see stars. But, stars have been seen from Mars' surface, as has Earth. Some examples are at http://pancam.astro.cornell.edu/pancam_ins...projects_2.html.

There are actually hot pixels visible in lots of images, but when there is more details to them, they get lost within the detail.

Sol141 clouds with dust devils. I've contrast stretched the sky and ground separately to bring out the details.
The DDs are quite tall contrasted against the clouds.
