ESA release images of 82 km wide icy Korolev crater on Mars

It wasn't long ago that we heard about scientists finding water on Mars' surface. Well, now the time has changed and we now have the actual pictures that suggest the possibility of water there might be true.

The European Space Agency (ESA) has released a few images that were captured by its Mars Express probe. The images show a giant crater called 'Korolev' on the surface of the Red Planet. The newly found crater has been named after chief rocket engineer and spacecraft designer Sergei Korolev, who is known for his contribution in building the Soviet space technology.

The crater was found in the northern lowlands of Mars. It is close to 82km wide and it encircles part of Mars' northern polar cap. It is said to be approximately 2km vertically deep.

The ESA said that Korolev is a well-preserved specimen of craters on the Red Planet, and is filled with ice and not by snow. It is filled with ice due to a phenomenon called a 'cold trap' caused due to the floor of the crater which is two kilometers beneath the rim.

The deepest part of the crater with ice act as a natural cold trap. The air that is moving over the deposit cools down and makes a layer of cold air that's always there above the ice. The layer ensures that the ice remains stable and doesn't let it heat up and disappear. Since air isn't a good heat conductor, it results in keeping the crater icy forever.

I don't understand one thing. It was always known that Mars' two ice-caps had water in them, ice water but still water, so why is this crater such a surprise ??

Also, I will tell you what the crater looks like - like the malai ( meat ) in a tender coconut.

That's a huge crater.....Mars is smaller in size than our Earth but still it has huge features like Olympus Mons is three times the height of Mt Everest.

Simply "AMAZING".

It's not a surprise (now). Just that these new pictures capture our imagination.

Contrary to some reports, this is not a newly found crater. In fact, this quadrangle is quite smooth and craters are clearly visible, especially one as large as Korolev. But surely, these hi-res data will deliver newer results.

Also, that picture is a perspective image, by adding the terrain data. The 'original' is the one right from above, again a mosaic of five strips.
