Now them Martians won't die of thirst, so this gives us more time to capture them and disect them.

Didn't we already know there was water on mars? Or was that frozen carbon mono/dioxide?

That's a lot of ice. I don't recall exactly what it was we found before, but this is pretty cool.

It's an important find, because while there has been quite a bit of speculation of the possibility of water, non had really ever been found before.

Analysis of the images over the comming months will no doubt spawn some more, and exciting theories over Mars. I would say the most pertinant question is, "Why the hell is it arranged like that?".

Figuring out why it's there, would help as a booster leg to other questions and answers.

well it looks like the asteroid meleted the ice behind the crater and it slowly leaked in through the hole at the top left which would explain why it looks like the ripple towards then ends, and then froze

it could be whatever happend on mars happend suddenly so thats why there are ripples. Or even if the meteor did break though the surface of mars and water poured out before freezing fragments of that meteor could of landed in the water causing ripples just before it froze.

Well, this is very interesting! Considering that the water/ice there is apparently reflecting a blue sky.

... Yeah nice one.

LOL i did wonder myself why its blue or whatever but for all we know that could just be a reflection of direct light off our atmosphere.

at a certain size water crystals are a strong blue colour because they reflect blue light strongly

Are you suggesting the European Space Agency did a Photoshop fake?
Would you be so sceptical if it was NASA who got the picture?
On a completely cloudy day the ocean is still blue.

I as implying that its fake.

Yeah ok. Its not just the colour of the water, the whole image looks like something from Delta Force. I may be wrong though..

basically you're a retard. You should probably read and not jump all over people, it gives you a bad reputation.
and FYI, I didn't know that it was the ESA, i actually thought it was NASA.

Yeah, it does look fake, but you have to remember that it's different than on earth, i actually think that the colors were ADDED later, but that's a real picture. Hense on the site they have a black and white picture of the exact same shot as one of the colors, why would they do that? seems like a waste of memory to me.

Joel, stop trying to immitate Jimmy.

Quote: " You should probably read and not jump all over people"

I read it, I'm not sure if I believe it though. I'm allowed to not believe it if I want.

Oh and also, don't call be a retard. I don't call you a retard for believing different things.

Mars does have an atmosphere, even the moon has an atmosphere.

and the reason for the color blue is because it is digatally coloured other wise you wouldnt see it. like for example pictures from nasa of those colourfull gas clouds from space. and coincidentally they do use photoshop.

Any spelling mistakes are totally In tensional.

Quote: "The colour images were processed using the HRSC nadir (vertical view) and three colour channels. The perspective views were calculated from the digital terrain model derived from the stereo channels.


The 3D anaglyph images were created from the nadir channel and one of the stereo channels. Stereoscopic glasses are needed to view the 3D images Image resolution has been decreased for use on the internet.

http://www.esa.int/SPECIALS/Mars_Express/SEMGKA808BE_0.html"


This tells us that the only image that is fake, is the perspective veiw of the crater. It is a 3D model, created by the output values of the stereo channel.

I seem to have been mistaken then. Thank you for clearing that up NanoBrain. To be quite honest that text you quoted there, I must have misread it before.

It could be due to Mars' atmosphere or lack there of, but that picture does indeed look rediculously fake IMO.

View the Hi-Res Colour Images, it might look weird but remember the circumstances.

You can't view the pictures and take earth as a comparison. Our atmosphere is might thicker, in the day-time we usually have several light sources for everything often create by Clouds, Dust, etc. Not to mention Mars has 2 moons from which light is reflected from at any given time.

As a result you have to think in terms of a more basic lighting model that it would have. If you take a look at the Hi-Resolution image you'll clearly see that the 'skybox' effect is nothing more than the typical prisom effect of a single light source hitting something at multiple angles. The greater the angle variation the different colour light is cast back. Due to less atmosphere (yes we have just as much down here as in the zone layers themselves how else do you think we can breath ) you have less impurities in what is being reflected.

It's quite funny cause the top quarter looks blue, the bottom looks like yellow snow
I'm still quite interested in the pattern though, some looks like a meteor or probably more accurately a comet. Then again there are signs on the hi-res that show more detail on the spread and it looks more like water itself has formed it from underground in some areas.

You must also not forget its a "stereo" photo, ie, a shot taken by 2 different cameras, so that'd work like the human eye, which makes it less flat than a normal picture

it could be a spaceship, explain why the *water* is in the center and an impact crater around it
