List of evidence for water on Mars Options

[pumpkinpie]

Does there exist a list of all the evidence of water on Mars, listed by spacecraft?

Ideally, it would be a list with a short description and a link to a story or news release. For example:

Mars Global Surveyor: NASA Images Suggest Water Still Flows in Brief Spurts on Mars http://www.nasa.gov/mission_pages/mars/new...s-20061206.html
Phoenix: NASA Spacecraft Confirms Martian Water, Mission Extended http://www.nasa.gov/mission_pages/phoenix/...x-20080731.html
Opportunity: NASA Mars Rover Finds Mineral Vein Deposited by Water http://www.nasa.gov/mission_pages/mer/news/mer20111207.html

I know I could spend some time and extend the list that I've started above, but if someone or some organization has already done it I'd hate to reinvent the wheel!

Thank you.

The linked Planetary Society blog article provides an interesting read on the faint young sun paradox with respect to long lived surface water on early Mars and puts to bed some of the hypothetical explanations. However the article did miss the hypothesis that the solar system transiting through interstellar dust clouds could have the effect of significantly increasing the sun's output through the capture of molecular hydrogen. That hypothesis has always made a lot of sense to me.

I saw two recent papers/references that seem relevant, or at least interesting.

FIRST, was a paper on the 11/22 year solar cycle and Jupiter (yes, related to the barycenter theory) which looked at
the 11.07 year cycle of solar atmospheric tides that results from Venus-Earth-Jupiter orbital resonances.

So, let's consider that Theory #1 the "solar cycle / planetary barycenter theory" might be correct
well,
let's consider that Theory #2 "Nice-Model" might be correct as well.

In that case, the early Sun had 4 gas giants between ~5 AU and ~17 AU.
Resonances would have driven massive solar dynamo effects.

Basically, if you have 4 gas giants on circular orbits within ~17 AU, you have tides stirring the Sun and stoking the fire.

SECOND is a combination of idea, the mention of lunar GRAIL data that the lunar surface is roughly 15% void space for the first few kilometers, and a review that the breccia and impact melt under Gale crater could be 17 km deep (for comparision, the Marianas Trench on earth is ~11 km deep) with an initial void space of 3,600 cubic kilometers.
This suggests that there is plenty of "space" for liquid water to exist in the Martian subsurface.
That implies that the real trick about water on the surface of Mars is keeping it from draining back down into the regolith.

Perhaps we only see Martian rivers when they run across compacted sediments or permafrost, otherwise, the water quickly soaks into the sand and gravel.

Flip the thinking to view rivers on the surface of Mars more like the meltwater channels on the top of a glacier, as soon as they encounter a lens of clean sand or a crack, they are gone.
