Evidence of water has been seen on Mars many times, but it is usually ancient, fleeting or frozen.
"While the discovery is a major one for researchers hoping to find life on Mars, no one's getting their hopes up-but they are tentatively preparing themselves for a real alien discovery in Mars" subsurface. In the planet's two polar regions, there are large quantities of solid water, or ice. Is there life on Mars?
However, according to the researchers, it could be pure water on Mars. The probe, built by the German Aerospace Center (DLR), will provide crucial data on how much heat escapes the planet and where liquid water could exist near its surface.
The radar apparatus of the European "Mars Express" has shown that the South pole of Mars to a depth of fifteen kilometers there is a lake of liquid water.
Mars is very cold, but the water might have been kept from freezing by dissolved salts. Then, concerned that their hope the bright spots might be water could blind them to other explanations, Orosei and colleagues spent nearly as long trying to demolish their own data.
The temperature is likely below the freezing point of pure water, but the lake can remain liquid due to the presence of magnesium, calcium and sodium. Surface features obscured by dust, the planet's cloud enshrouded south pole is tilted more toward the Sun.

Microbial life survives some of the harshest conditions on Earth, including within subglacial environments. At that time, the Sun, Earth and Mars fall in a straight line, with Mars and the Sun on "opposing" sides of Earth. However, after billions of years the effects of erosion have taken their toll here and, while still quite large, the Medusae Fossae Formation on the Red Planet is not what it once was.
"This subsurface anomaly on Mars has radar properties matching water or water-rich sediments", says Roberto Orosei, principal investigator of the MARSIS experiment and lead author of the paper published in the journal Science today.
He suspects Mars may contain other hidden bodies of water, waiting to be discovered.
However, Stillman, who was not involved in the research, said another spacecraft, or other instruments, need to be able to confirm the discovery.
Unlike Earth, Mars' more elliptical orbit has a greater influence on its seasonal changes.
"There are likely similar water deposits below the ground all across Mars". Unfortunately, we're getting the short end of the stick on this one.
