Re: Mud Flows on Mars

*Damn it.  I'm not sure it's linkable...try this, under "New Stories"..."Photos show mud flowing on Mars".  Also check out the story below it ("Historic Mars lander 'did find life'").

Re: Mud Flows on Mars

Let's try this, Cindy.

It's a very interesting theory! Note that of course, he's not seeing actual flows (impossible considering the resolution of the imagers, in my opinion), but he noticed that over time the dunes seemed to change, measuring the albedo proved this. His explaination needs further study, though. Can it be shown that martian wind could create the same levels of albedo change? How much change is occuring over a period of time (we might have to throw out higher thermodynamic ideas if it's potentially cyclic- sand dunes can be built up and torn down by wind, I can't think of a feasible theory building up mud dunes)?

The amount of solar radiation reaching the surface of the earth totals some 3.9 million exajoules a year.

*Thanks Josh! 

How do you do that, anyway?  I think Bill has done the same, in the past.  It is a hyperlink?

Re: Mud Flows on Mars

Wow old again but we have talked about water and regolith in other topics that we see in crater ejecta that shows that we had mud on mars. Splus or something like that If I remember corretly.....

Splashdown! Crashing into Martian mud

An impactor smashing into an ice-rich surface gave rise to the complex flow features around this ancient crater on Mars. Impacts of comets and asteroids have shaped the surfaces of rocky planets and moons over the Solar System's 4.6 billion year history, and can reveal environmental conditions at the time of their formation.

During an impact, the energy transferred to the ground goes into melting and vapourising the impactor and parts of the surface, as well as excavating vast amounts of material from the ground, throwing it out onto the surrounding terrain as a blanket of debris.

The characteristics of the ejected material can provide clues as to the conditions of the planet's surface and its general environment.

Where there is mud we have
Ice mined on Mars could provide water for humans exploring space

A flattened map of the surface of Mars shows the location (red box) of the buried ice deposits in the Deuteronilus-Protonilus Mensae region.
Buried ice
The Protonilus - Deuteronilus Mensae region on Mars is located in the northern mid-latitudes of Mars (~8 E and 60 E 38N and 50 N).

This region is host to numerous land forms which appear to contain large buried ice deposits, hundreds of meters thick and several kilometres wide

Re: Mud Flows on Mars

There are several nice mudflows and a huge landslide that covers 66 square miles (counting the scarp) in the Shalbatana Vallis canyon. This landslide is also right next to the recently published strandlines in the canyon. You can Google my blog post on the landslide. The title is: Massive Martian Landslide found in Shalbatana Vallis using Google Earth "Mars"

Re: Mud Flows on Mars

Welcome to Newmars Britt and I help you come back to post often.
Now shifting to self educating mode on "Massive Martian Landslide found in Shalbatana Vallis" .... Found you reference http://www.marsroverblog.com/discuss-21 … allis.html

Shalbatana Vallis

Its a little hard to see if you did not know where to look for sure.

https://www.boulder.swri.edu/~harrison/ … ke2008.pdf

These all relate to water flowing in a channel at somepoint in mar's history....
