Mesmerising New Images of Mars Show Spring Arriving Violently on Its Frozen Dunes

At Science Alert: https://www.sciencealert.com/mesmerising-new-images-of-mars-show-spring-arriving-on-its-otherworldly-frozen-dunes

At UK Mirror: https://www.mirror.co.uk/science/martian-winds-create-bizarre-ripples-20079413

 

"During winter in the polar regions, a thin layer of carbon dioxide ice covers the surface and then sublimates – turns directly from ice into vapour – with the first light of spring. In the dune fields, this springtime defrosting occurs from the bottom up, trapping gas between the ice and the sand.

"As the ice cracks, this gas is released violently and carries sand with it, forming the dark patches and streaks observed in this CaSSIS image. "

A planet covered in white chocolate? That's the first good argument for going to Mars I've heard so far.

What a shame it is not white chocolate, but as I got no chance of ever going there anyway, the photos and explanations are actually better. Amazing.

Neither do I, but I childishly hope they find either life or fossilized lifeforms, even if they are microscopic I'd be happy.

You, me and just about every scientist on the planet would be happy.

We may not have to wait for the sample return mission for that though. Two rovers are being launched next year, NASA's Mars 2020 and ESA/Roscosmos' ExoMars - Rosalind Franklin. Both will be equipped to search for life.

I just realised that this ISN'T the Mars Sample Return Mission thread. D'oh!. Still the comment is still valid.
