#Ancient Mars had long-lasting lakes, rivers: Nasa Mars harboured long-lasting lakes and water streams about 3. 8 to 3. 3 billion years ago,
boosting the odds that life may have existed once on the Red planet, scientists, including one of Indian-origin,
have found. Using data from the Curiosity rover, Nasa's Mars science laboratory/Curiosity team has determined that, long ago,
The findings build upon previous work that suggested there were ancient lakes on Mars, and add to the unfolding story of a wet Mars, both past and present.
Last month, Nasa scientists confirmed current water flows on Mars."It's clear that the Mars of billions of years ago more closely resembled Earth than it does today.
Our challenge is to figure out how this more clement Mars was even possible, and what happened to that wetter Mars,
"said Michael Meyer, lead scientist for Nasa's Mars Exploration Program at Nasa Headquarters in Washington.
Before Curiosity landed on Mars in 2012, scientists proposed that Gale crater had filled with layers of sediments.
Some hypotheses were"dry, "suggesting that sediment accumulated from windblown dust and sand. Others focused on the possibility that sediment layers were deposited in ancient lakes.
The latest results indicate that these wetter scenarios were correct for the lower portions of Mount Sharp.

#NASA confirms liquid water flows on Mars NASA has announced that it has discovered flowing liquid salt water on Mars during the Red planet summer months, in

#Salty Water Flows on Mars Today, Boosting Odds for Life Liquid water flows on Mars today,
boosting the odds that life could exist on the Red planet, a new study suggests. The enigmatic dark streaks on Mars called recurring slope lineae (RSL) that appear seasonally on steep,
relatively warm Martian slopes are caused likely by salty liquid water, researchers said.""Liquid water is a key requirement for life On earth,
"The presence of liquid water on Mars'present-day surface therefore points to environment s that are more habitable than previously thought."
by studying images captured by the High Resolution Imaging Science Experiment (Hirise) camera aboard NASA's Mars Reconnaissance Orbiter (MRO).
100 meter-long streaks (called recurring slope lineae) are flowing downhill on Mars, and are inferred to have been formed by contemporary flowing water.
RSL occur in many different locations on Mars, from equatorial regions up to the planet's middle latitudes.
Ojha and his colleagues scrutinized data gathered about four different RSL locations by another MRO instrument, the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM."
we can deduce the mineralogical makeup of surface materials on Mars, "Ojha said.""What we found was that at times
and places when we see biggest RSL on the surface of Mars, we also found spectral evidence for hydrated salts on the slopes where RSL form."

"This property vastly increases the stability of brine salty water on Mars, "he said. Perchlorates can absorb atmospheric water,
if Mars'air is the source of the brine flows. Other possibilities include melting of surface or near-surface ice or discharges of local aquifers."
"It is conceivable that RSL are forming in different parts of Mars through different formation mechanisms,
the Red planet was a relatively warm and wet world that could have supported microbial life, at least in some regions.
Mars is extremely cold and dry today, which is why the discovery of RSL sites has generated so much excitement over the past four years:
But the new results don't imply that life thrives on Mars today, or even that this is a likely proposition, Ojha stressed.
#There's water on Mars, NASA confirms There's water on Mars, and it flows there today.
In an eagerly anticipated news event, NASA revealed this morning the evidence of liquid, flowing seasonal water on the Red planet.
Water often signals life, so this new discovery gives hope to the search for life in our solar system.
Data from various probes and rovers like Curiosity and the Mars Reconnaissance Orbiter have provided researchers with evidence concluding that there is flowing water on present-day Mars. Scientists understand that Mars was once Earthlike with large
today's revelation confirms that Mars has harbored water in the past, and that water exists there today.
Michael Meyer of the Mars Exploration Program at NASA explained, "We found the active process on Mars today that shows that water was a likelihood."
"He continued with a description of the geological features that caused scientists to suspect water prior to the confirmation of its presence.
However, recently scientists found a way to analyze data from the Mars Reconnaissance Orbiter by extracting data from the pictures on a per pixel level.
This allows scientists to study smaller details on the Red planet's surface and those details provided the new information.
Findings show that hydrated salts are present on the surface of Mars. Hydrated salts would mean that the water on Mars is briny.
Also, water on Mars could aid in the human exploration of the planet. Water on Mars would be a crucial resource for astronauts visiting the planet or for long-term colonists.
Of course scientists will need to study the nature of the water to know the full implications.
Another possibility is the future Mars 2020 rover or other rovers designed for the task.
The discovery of liquid water on Mars leads to more intriguing questions and mysteries. If there has been did life on mars,
