Mariner 9 (and Viking) provided us with the imagery that gave us our first solid indication of past Martian water. However, the only thing we actually knew from Mariner 9 was that the geomorphology of some features appeared similar to those formed by the flow of liquid water on Earth. All that could be assumed is that whatever "carved" the Martian features likely had a viscosity similar to that of liquid water. In fact, there is still some debate today regarding certain features having been formed by ice and/or wind instead of liquid water. The mineralogy is what makes these current findings significant. Specific minerals and rock types, like specific plant species, are found in certain environments that are conducive to their "growth." By studying the lithology, we can determine the history of Mars as a planet. -------------------- "I do not know what I may appear to the world, but to myself I seem to have been only a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me." -- Sir Isaac Newton Post Extras       Entire thread Subject Posted by Posted on Diverse, Wet Environments on Ancient Mars LadyAstronomer 07/16/08 05:43 PM Re: Diverse, Wet Environments on Ancient Mars ericjacob613   07/18/08 02:58 AM Re: Diverse, Wet Environments on Ancient Mars David Knisely   07/19/08 02:29 AM Re: Diverse, Wet Environments on Ancient Mars ericjacob613   07/19/08 11:41 PM Re: Diverse, Wet Environments on Ancient Mars LadyAstronomer   08/10/08 09:15 AM Re: Diverse, Wet Environments on Ancient Mars Joad   08/11/08 09:49 PM Re: Diverse, Wet Environments on Ancient Mars rick rian   08/11/08 10:59 PM Re: Diverse, Wet Environments on Ancient Mars LadyAstronomer   08/11/08 11:48 PM Re: Diverse, Wet Environments on Ancient Mars Rick Woods   08/27/08 09:53 AM Re: Diverse, Wet Environments on Ancient Mars llanitedave   08/27/08 11:22 AM Re: Diverse, Wet Environments on Ancient Mars Rick Woods   08/27/08 11:44 AM Re: Diverse, Wet Environments on Ancient Mars RRaubach   08/27/08 07:21 PM Re: Diverse, Wet Environments on Ancient Mars Rick Woods   08/28/08 08:18 AM Re: Diverse, Wet Environments on Ancient Mars llanitedave   08/28/08 10:10 AM Re: Diverse, Wet Environments on Ancient Mars llanitedave   08/27/08 01:20 PM Extra information 4 registered and 2 anonymous users are browsing this forum.
