Is There Water Available On Mars?

Round Pebbles On Mars

There has been a debate going on for long on whether or not there is water in Mars. But, this question seems to be leading us more towards the answer that Mars definitely has water as now the Curiosity rovers have discovered smooth and round pebbles on the surface of the Mars which indicate that water seems to be flowing across the Mars’s surface. The smoothness that is seen in these pebbles suggests that these small rocks might have rolled and bounced along in a stream that could be about 4 inches and 4 feet deep. This is what the scientists feel after seeing the smoothness on the pebbles.

Pictures From Mars Rover
Mars Rover did click a lot of pictures of different areas on the Red Planet where there was a good concentration of pebbles. On close examination of these pebbles, the size and shape of these pebbles indicate to researchers that the stones might have traveled long distance sin water in order to attain such round shapes. It is also thought that the pebbles were part of a very old and ancient riverbed. These rocks were found just near the Mars Rovers curiosity’s landing site that is between the base of Mount Sharp and the northern rim of Gale Crater.

Findings About The Rocks
A total of over 515 stones collected from the Mars were thoroughly studied by the scientists. They divided Hottah, a photo mosaic of an area, into small frames in order to study deeply about the rocks.

  • These rocks were cemented and joined together and measured about 2 millimeters to 41 millimeters in total. All the stones that the researchers studied were smooth and round.
  • The scientists were of the opinion that water must be the main cause for the stones to turn into smooth and round pebbles and that too these rocks would have turned into smooth pebbles overtime and not about a few years back.
  • If it was to be believed that wind could be the source for the  stones to turn into pebbles, but then the winds can only turn rocks into rough an angular stones and not into smooth pebbles.

This explains that water was clearly present on the Mars.

Water In Mars
Scientists are of the belief that for the pebbles to have found a round and smooth shape, there should have been streaming body of water with a depth of between 10 cms and 1 m and a rate of flow of approximately 1 meter per second.  Even though present-day Mars is a waterless place, there is considerable proof that body of water probably ran on the Red Planet’s surface many billion years ago. Both the NASA’s Spirit and Opportunity rovers, who reached down on Red Planet in 2004, discovered signs of the planet’s wet past. In 2008, the National Aeronautics and Space Administration’s Phoenix Mars Lander reasserted the being of current ice on Red Planet. The outcomes of the fresh survey evidence that Curiosity, which was set in motion in August 2012, has already attained one of its primary targets: to look into whether surfaces of Mars could have been inhabitable for old microbial life. The answer seems to be a very big yes.
