Pretty exciting news! Mars seems to be at least a little wet. The NASA account is below. Makes me wonder if we can get rover there to directly sample the area. If it were only that simple. Time for a “glide-in” rover of some type.
I wonder if the researchers have speculated on amount of water seeping up based on the environmental conditions present – what is the minimum amount of water in a brine concentration to resist freezing at minus 23 C / minus 10 F to make such wet spot.
How much of that moisture is lost to the atmosphere is another question, could it be the planet is still drying out?

The image caption:
Dark narrow streaks, called “recurring slope lineae,” emanate from the walls of Garni Crater on Mars, in this view constructed from observations by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter.
The dark streaks here are up to few hundred yards, or meters, long. They are hypothesized to be formed by flow of briny liquid water on Mars.
The image was produced by first creating a 3-D computer model (a digital terrain map) of the area based on stereo information from two HiRISE observations, and then draping an image over the land-shape model. The vertical dimension is exaggerated by a factor of 1.5 compared to horizontal dimensions. The draped image is a red waveband (monochrome) product from HiRISE observation ESP_031059_1685, taken on March 12, 2013 at 11.5 degrees south latitude, 290.3 degrees east longitude. Other image products from this observation are at http://hirise.lpl.arizona.edu/ESP_031059_1685.
The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., Boulder, Colorado. NASA’s Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter Project and Mars Science Laboratory Project for NASA’s Science Mission Directorate, Washington.
