I’ve seen sensationalistic headlines like this before, but the team seems rather convinced. Here’s the image that makes believers out of them, released just this morning:
That little trench, dug by the lander’s digging tool, is a foot long and a little less than an inch deep. There was a thought that maybe the white stuff was some kind of salt deposit. But see how it disappears? Salt doesn’t do that.
Now the digger has hit something hard a little deeper down. The Phoenix team is hopeful that it’s an ice layer. But they can’t be for sure just yet, since a technical glitch temporarily suspended transmission of images. Not a problem, though. A software patch should fix the glitch and then they can continue to ‘wow’ us. As of now they are actually well ahead of schedule. Good stuff, guys!
