Mars is the fourth planet in our solar system, away from the Sun. It is also the smallest planet in the Solar System straight after Mercury. Many times it is known as the “Red Planet” because of its red surface formed by iron oxide. Scientist for many years has tried to find it. There has been news about evidence of water and life exists on Mars, however, in 2015 scientist have to confirm that there is evidence of water found on Mars.
30 March 2004, it was suggested that science has discovered methane on Mars, which could be a great breakthrough in finding life on Mars. On 2 March 2004, a scientist claimed that the rocks on Mars once had water on them. Scientist Steve Squyres said, “These rocks were modified in liquid water and may have been precipitated in water.”
A recent discovery in the year 2015 states that liquid water runs down the canyons and crater walls over the summer months on Mars, according to scientists this increases the chances of life on Mars. The water can run as far as 100 meters downhill in the summertime and dry out in the autumn as the temperature of the surface increases.
The mystery in this discovery is that scientists are unsure of where the water generates from. A theory is that it may rise from beneath the ground which is said to have icy or salty aquifers. The other concept is that it may be generated from the thin atmosphere of Mars. Michael Meyer, the lead scientist on Nasa’s Mars research program states, “There is liquid water today on the surface of Mars, because of this, we suspect that it is, at least, possible to have a habitable environment today.”
The realm where the water has been discovered can be a major step and spot for Nasa and other space agencies to search for further evidence that Mars can support life, and give chances for future human missions in the future to gather natural water supply. Jim Green one of the employees in Nasa said, “Mars is not the dry, arid planet that we thought of in the past, liquid water has been found on Mars.”
Years ago Nasa’s Mars Global Surveyor took pictures of something like water bursting through a channel wall and flowing around the rocky land.
