We've got some big questions about Mars, but one of its most compelling mysteries just got a lot more intense.
"Recurring slope lineae" (RSL) are dark streaks, first discovered in 2011, that appear seasonally on parts of the Mars landscape. In 2015, researchers took RSL as evidence of active salt water flows on the red planet. In 2017, new findings suggest RSL may actually be from shifting sand and dust.
NASA titled its 2015 release "NASA Confirms Evidence That Liquid Water Flows on Today's Mars." Monday's release is called "Recurring Martian Streaks: Flowing Sand, Not Water?" It shows how new evidence can cause scientists to reevaluate previous findings.

Lots of interesting things out there, many of them are outside our solar system.

NASA has invested so much into finding water on Mars ... just so they can say there is nothing special about the Earth.
We still haven't found any living Civilization in the Universe!
Then we will find where all the living Aliens are from
Well, since liquid water is the most likely source for life, detection would be a good start, excepting ideas for silicon based life.
No civil on dis planet, dat fo sho.
While Mars may be eroding, are Muslims feeling the “outreach” of NASA’s core mission?
yes, but Mars isnt one of them. it is inside the solar system i think.....
“We still haven’t found any living Civilization in the Universe! “......
Does that include all of “us”? (sarc)
Even silicon based life would have to use water or some similar liquid. The chemical properties of silicon make it similar to carbon in certain ways.
NASA is recruiting—for future casualties on Mars. :-(
We all know what is on Mars... It’s the same thing we found on the Moon... It’s called dust, dirt, sand, rock, etc., etc. Going on missions to the Moon and Mars is a waste of resources.
A better idea, design less expensive robotic missions for local exploration... Then take those savings and add more on top of that to develop a propulsion system that will travel fast enough to reach another star within a humans life time. Until we find a way to send a spacecraft faster than the speed of life, we are wasting our precious time.
And who knows? If we put all our resources towards that end we may accomplish the feat of traveling to another star within the next 4 or 5 generations.
As for travelling to Mars... If you want to get a feel for that experience, go to the Mojave Desert and hang out there for a year or two... Same diff.
When the subject is science, most of what we “know” is wrong.
We can always hope.
The problem with a ‘super-duper’ telescope is that anything you ‘see’ thru it is waaaay far back in time.......................
Absolutely true. The Horta's corrosive secretions are proof of that.
Other than the local idiots, all the others are hiding. Any sufficiently developed star-faring civilization would see another as a competitor and competitors are eliminated before they cause trouble ... See “Dark Forest” by Cixin Liu
