[Flowing Water on the Surface of Mars]

Water has long been known to exist on Mars. In addition to the observable frozen water at its poles, it has been hypothesized that liquid water exists below the Martian crust — the planet's most promising location on our search for life.

These images were captured by the Mars Reconnaissance Orbiter (MRO) as it passed over the deep canyons of Valles Marineris (located in the equatorial regions of Mars) while facing the sun. You will notice narrow, dark markings that form flow-like features on the sloping terrains.

Researchers believe the observations are consistent with intermittent flows of briny water indicating abundant liquid water near the surface of equatorial regions of Mars.


This research adds significantly to evidence that there's liquid water deep below the Martian surface. The idea of subsurface liquid water is particularly exciting because of the possibilities it holds for harboring life. If this liquid water is welling-up to the surface periodically, we might even be able to sample it within the near future (without having to drill 200m below the surface).

In 2011, evidence of these dark streaks first appeared — but the same researchers believed the streaks were caused by 'dust avalanches.' With the new observation of hundreds of thousands of streaks within 20 degrees of the equator, the simplest explanation appears to be liquid groundwater welling up to the surface.


The next Mars rover is scheduled for 2020. +NASA is still evaluating objectives and determining payload as of Spring 2014. With a little hope, perhaps a location like this could be incorporated into a new directive.

+NASA was the recipient of a healthy budget this year, it would be completely feasible to have a small lander drill and lase the surface where water is present.

The +Nature Publishing Group article attached brings up the interesting point of sterilizing a spacecraft before it comes into contact with these so-called 'special regions' sites that may host life. The article says that spacecraft or their components have to be sterilized meticulously with heat, hydrogen peroxide vapor, or ionizing radiation to kill off as much Earth life as possible.

I'd say it's time for a launch, but as is the only issue with being a space enthusiast — everything happens in a matter of years, not months.

Awesome! +Jana Slipski you should get this. :P
What's on your geek gadget gift list this year, either for you or as a gift?

I thought this Portal Sentry Turret was cute:

Fitbit has a new wireless pedometer:

Here's a cool USB LED:

Or if your company went public this year, maybe the Tesla Model S:

One year I gave my grandfather a photo blanket with a picture of his barn:

How about you--what fun or neat things do you like this season? Leave a link so other people can get gift-giving ideas. :)
