Have you been keeping track of what Phoenix has been finding on Mars? There’s been lots of digging of holes, baking, peering at things under microscopes, and so forth. And, wonderfully, it has all been guided, monitored, and watched from here on earth. From all of this, there’s now very direct evidence for ice, for example. (Dig a hole, find white flaky chunks which disappear after exposure to sunlight…) (Image left (click for larger) is from the mission (credit: JPL/Caltech/NASA) and shows the before and after. Keep your eye on the darker corner, blown up in the inset.)
There’s a story from the AFP here, and one by Alicia Chang (AP) here. There’s a photo gallery there, and of course you can see the photos and more information at the mission site itself.
