Just posting a weird thing I found searching Google Mars ( google earth) Looks like a giant ice slab in a crater. What do you guys think?  Location: 73.5964456917, 2.61441480541

Ice on Mars is of CO2.

If the temperature in the crater is lower than the sublimation of CO2 -78.5 ° C, it is realistic to expect CO2 ice.
If you were thinking of H2O, just forget it.

What? There is plenty of water ice on Mars, both underground and on the surface.

Why would you think otherwise?

Wouldn't this (OP) be more likely to be sand?

It certainly could be, hard to tell as I only have the image posted and only seen on my phone.  I was planning on looking at Google Mars today, but other tasks intervened. 

Thus, I was merely pointing out that there *is* water ice on Mars. I should have been more clear.

Oh I know, I was asking because you're the astronomy nerd. And I haven't ran into you lately.

Oh, I appreciate the kind words, although I am hardly the most savvy in that area on these forums :unsure: Real life has kinda taken over for a while with work and a 10 year old daughter that needs play dates, goes to piano lessons, girl scouts (now I have tried manning a girl scout cookie sale booth as well - who would have thunk it), etc. You get the drift :P

More than five million cubic kilometers of water ice has been identified on Mars, on or below the surface. While it's not impossible, what's in that crater is more probably frozen CO2 as water ice sublimates rather quickly in Mars' thin atmosphere.

Sand dunes are often found at the bottoms of craters on Mars. These light-colored features do not appear to be flattish ice deposits, but rounded hummocks; shadowed on the bottoms, and in bright Sunlight at the tops. The color is not white, but pale yellow. Probably sand dunes.

Overwhelming evidence that there is water flowing on Mars, and sure we can say that it is all saline,..... :mellow:

We can also say that every time Hubble is pointed at Mars, it malfunctions.....!

Yeah, nasa certainly hasn't made press announcements about possible water on the surface or the presence of water ice in the past. No sirree Bobby. Never a word about that at all.

Hubble's resolution isn't good for something as close as Mars.

Arrm, they have actually. :o

Oh, l know pretty p**weak, compared with it getting bogged in some, (current rover) but still they did wrestle with what is left of their consciences, and said something.

B)PS l probably made a spelling mistake if anyone wants to condemn me to the pits of hell?

Yeahp. That's my point. They've been looking for water in the surface and announced the signs of it for decades. Solid hints of it are enough to get a press release for us science nerds. 

 And your statement about Hubble is simply wrong. Check out its specs, Mars is too close and small for it to visualize. 

Your photographs are just showing you are looking at things and not keeping the pm frame of reference in mind to what you're looking at, or have a small pool of references to compare them too.

Too close and small?

All l know is what it keeps showing, (Hubble) isn't in line with established,...how can l put this....mass media warm and fuzzy data.

:blink:

Hubble is geared for extreme long distance viewing, not nearby planets. It can image planets but not the sort of view you'd get from an orbiter or lander, or even earth based telescopes. 

You're not going to get detailed images from Hubble or the Moon or Mars. Do you think that's where this image came from? 

And if you are claiming this is a cover up by NASA or ESA or CSA, then why are all raw images released to the public un the first place?

I know that Hubble didn't take this.

Great. So you also know that NASA is cleverly hiding these images by making them public? Knowing a few planetary geeks, the possibility comes to mind that many hundreds of people pour over each burst of data as it comes through, just regular nerds doing nerd things. What do they make of these images? 

 

What's the context? Not single, cropped, isolated, color inverted images 

And that James Wallace, despite his claims, is not listed as doing any work with Pixar or James Cameron? 

 As for Hubble, since you bring it up, what's the weird stuff you mention?

It's fun, but I certainly truly enjoy still discussing here at UM when I have the opportunity. Unfortunately for me, if I can't go all in and not leave a discussion hanging I try not to engage. And it is tough to find time for these days (takes a lot of research normally). So I am currently grappling for the low hanging fruit just to stay engaged :rolleyes:

Cheers,
