A question here
There are signs that in the past there was liquid water on Mars. So lets assume thats true. Since the gravity on Mars is much lower than on Earth, so how does water (waves) behave on Mars compared to Earth? Someone did say, that waves would have been much higher but also much slower. Is this true? Does anyone have an animation where you can see a waive on Earth in comparsion to a wave on Mars? Thanks |

Space.com article says that the crust of Mars is colder (and thicker) than previously thought.
From the article: "Unexpectedly, the radar scans also revealed the massive weight of the ice cap does not deform any underlying sediment. This implies the crust beneath the cap is strong — more than 180 miles thick (300 km). To have such a thick crust, "Mars might be colder than we thought," Phillips told SPACE.com. As a result, any liquid water that might be underground has to be buried even deeper than once speculated. "If one thought that liquid water was 5 kilometers deep (3 miles), it's now at least 30 percent deeper than that," he said." (The article to be published in the May 15 issue of Science is not yet available.) I have a really ignorant question, here: What is the ductile strength of sediment with interstitial ice? Is it stronger or weaker than normal sediment? -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
