Re: Let it snow, let it snow, let it snow...

article quotes how its happening:

The researchers' atmospheric model revealed that the cooling of water-ice cloud particles during the cold Martian night can create unstable conditions within the cloud, triggering the development of a descending plume of snow.
These turbulent storms, which can only form at night, act to vigorously mix the atmosphere and, in some places, deposit snow on the Martian surface.

I took this screen image just before NASA removed it from this video online, (also including third party) you can still watch this one, but this part is frozen. Or the part showing live video of Curiositys decent showing a blue sky in the background, although the first image we got were b/w. Then color later on, showing virtually no blue sky.

Overwhelming evidence that Mars has a sky like ours, but as to why NASA keeps up the act? Probably has something to do with the fact that you need at least 17% oxygen in an atmosphere in order to create a blue colorization.

And Earth has around that much, so, it opens up a lot of doors.

That might save a lot of work and delivered mass. We might just collect it on a mylar film with edges suspended above the ground
