Water and life on Mars

The closest distance from the Earth to Mars is 206.6 million kilometers and the maximum distance is 249.22 million kilometers, but in August 2003 it came very close to the Earth, then its distance from the Earth was reduced to only 58 million kilometers. For the first time in the last 73,000 years, Mars was so close to the Earth. Taking advantage of this, many investigative vehicles were sent towards Mars. (Although the United States and Russia sent 34 unmanned vehicles in the past. They often failed.)

The European Space Agency's 'Beagle-2' embarked on a voyage of life on Mars was not known, but the twin robotic missions 'Spirit' and 'Opportunity' of 'NASA' of Mars on 4 January 2004 and 25 January 2004 respectively Have touched the surface.

The high-resolution stereo camera (HRSC) of the Mars Express sent a picture of the South Pole of Mars, in which structures built by canal or river flow are clearly visible, yet a class of scientists It is assumed that watery structures can be made of carbon dioxide instead of water. But in the past, there was an abundance of hematite presence from NASA's Mars Global Surveyor. Which is impossible to form without the presence of waterless lake or hot streams.

The high resolution stereo camera of Mars Express covered 275 km on 14 January 2004. In the south-north direction of the 'Velis marineris' ravine from a height of 1700 km long and 65 km wide strip was photographed. The lower part of the picture is clearly visible from the water flow.

The original question is still unanswered. If there was ever water on Mars, where did it go? And when there was water on it, did life flourish in that sunrise or not?
