This is CVS, I on the World. I'm John Bachelor Bob Zimmerman. He keeps the website behind the black and we go to the surface of Mars. Curiosity. Where is it Bob? Curiosity is still climbing Mount

Sharp. It's actually about to leave Gives Valis and move to a parallel canyon

to the west, but in its final days it took this really cool picture of a corroded rock probably made

of sulfur on the ground. So I posted on behind the black because it's really corroded and

weathered. The sulfur is kind of soft so it's not surprising.

The weathering suggests wind, it could also be flowing water, it could be glacial ice in the

past, we don't really know.

The scientists why they wanted to take a good look at it.

It's just very, very cool.

So that was my curiosity update.

It's still moving up the mountain and it's actually going to go down the mountain a little bit

to get around. I want to go down the down a little bit to get around.

I want to comment on the rock bomb.

Have we seen anything like this before?

Not really, but this is sulfur, and we only saw the first real pure sulfur recently about a few months ago and that

sulfur was sulfur crystals and it is more sulfur on the surface. They're in what

they call the sulfate bearing unit so it's got a lot of sulfate in it and sulfur on the surface is

unusual on earth so how it reacts to an atmosphere and an environment you're going to see

things that we don't see on earth generally and that's what this is.

It looks like a very large Danish is what it looks like.

The krella.

Yes, everybody reached for your coffee.
