According to reports from Nasa's Opportunity probe, there is a network of water spread across a vast area hidden beneath the floating dunes on Mars's surface.
In 2004, the red planet exploration Opportunity found minerals and round spherical rocks in the volcanic region of Mars, a sign of the existence of surface water. Mars.
The robot explorer ship also found similar signs at Victoria Crater, 3.5 miles away (equivalent to 6 kilometers). These are extremely special rocks at Victoria's volcanic edge and most likely the fossil remains of ancient sand dunes.
Professor Steve Squyres, chief investigator of the Mars Self-Propelled Robot Project of Conrnell University in New York State, said the new findings confirm the assumption that water exists on Mars. a wide range, not just isolated islands.
He said: 'It is clear that the guesses about the existence of water on a large scale are grounded because we also find similar signs in many places separated by miles. And you know water is an essential component of life. '
In 2006 there was a fiercely disputed issue whether or not the ship should be exposed to Opportunity in Victoria's crater. Due to the rugged terrain of the area leading to the crater, it is possible that the long-term exploration system with the ship's cakes will be damaged.
At that time, managers in this project feared that if any damage occurred, Opportunity would never escape the volcano.
However, according to Squyres, the adventure drill proved that the decision to take the probe into the volcano was worth it. It is now out of the safe crater and is trying to make it to a larger volcano, 8 miles (13.5 kilometers) away , the volcano Endeavor.
Professor revealed: 'If we do not go to Victoria volcano to observe, we have no way to know the extent of water's appearance. We were able to penetrate into the volcano and were also able to get out of there. So we have successfully completed our mission. '
