Press conference in a half hour or so on something new from Mars.
Water is my assumption.

Liquid water, should have been more specific.

Mars has water on its surface, and it's in liquid form at least some of the time.
NASA on Monday announced the results of a new study showing that salty liquid water flows seasonally on Mars, giving the red planet one of the essential ingredients for life.
The study, published online by Nature Geoscience, focuses on the mysterious recurring slope lineae, or "RSL" -- narrow, streaky features on the planet's surface spotted by NASA’s Mars Reconnaissance Orbiter spacecraft.
The RSL are typically about 15 feet in width or smaller, and appear on slopes during the planet's warm seasons. They fade during cooler seasons, then reappear the following year as the planet gets warmer again.
While NASA has suspected that the RSL are made of salty brine, previous analyses of data from the spacecraft's Compact Reconnaissance Imaging Spectrometer have found neither salt nor water.
"These soggy streaks suggest that there are vast reserves of underground water, presumably the last remains of lakes that may have once dotted the landscapes of this planet," said Seth Shostak, senior astronomer and director of the Center for SETI Research, who was not involved in the new study.
"Consequently, if life began billions of years ago during Mars' more clement youth, its progeny could still be hiding out a few feet underfoot," he said. "That would make the task of finding some red planet biology far easier."

If true then it means colonization is feasible, but I am suspicious. Has anybody else noticed the timing of this and the release of a certain Matt Damon film?

This is an amazing and Very Important Discovery. Interesting that NASA could first confirm Pluto has a signifiant nitrogen ice. Who'dAThunk?
Strong implications for water in other places out there.
And then life? I hope I live long enough to learn the answer to that question!

Everyone know that mushroom spores traveled here from Mars, landed, spread across the land, the monkees at them, and evolved higher brain functions to build space ships to travel to Mars so it can feed on your now large and delicious BRAINS! Mwahahahaha

What do you suppose the lines crossing the fall line on the left are from? Is it windy there? Wind driven rockfall? What falls naturally across a slope rather than down it? Wind+reduced gravity=something traversing a slope?

Ablation zone or ablation area refers to the low-altitude area of a glacier or ice sheet below firn with a net loss in ice mass due to melting, sublimation, evaporation, ice calving, aeolian processes like blowing snow, avalanche, and any other ablation. The equilibrium line altitude (ELA) or snow line separates the ablation zone from the higher-altitude accumulation zone. The ablation zone often contains meltwater features such as supraglacial lakes, englacial streams, and subglacial lakes. The seasonally melting glacier deposits much sediment at its fringes in the ablation area. Ablation constitutes a key part of the glacier mass balance.
The amount of snow and ice gained in the accumulation zone and the amount of snow and ice lost in the ablation zone determine glacier mass balance. Often mass balance measurements are made in the ablation zone using snow stakes.

Sounds reasonable, but I'm obviously no geologist.

Dust devils leave tracks on Mars. I think maybe dust devils are forming in the turbulence on the lee side of that hill and making a bunch of tracks in that one area.

Hadn't considered that one, but it makes sense.

They're thin skinned depositional laminae that contain briny evaporites (salty minerals). The real question is why do they seem to propagate specifically from these horizons? Is it ground water I think so.

Pyro thanks for paging me. Could have helped you out, but I hardly ever visit Supertopo, perhaps my ears were burning....
It's not a surprise that there's liquid water on Mars, its get above freezing in the summer at the equator, plus I bet those crater walls are sun traps. Our view of Mars has gone from moon-like to dry to lots of water everywhere, 99.999% of it is frozen solid underneath a layer of Martian dust. Lots of glaciers there, and lots of jagged glacier carved mountain ranges.
There are NASA plans to send people, but no money so we'll see how far that goes. JPL has a mission next year (InSight - launch March 2016), it's a stationary lander to detect Marsquakes. M2020 is currently being built at JPL, it's another big rover to, among other things, cache soil for subsequent sample return.
I honestly think I'm going to be dead before I see people there.
