An article on the Internet
There are still no signs of little green men, but NASA announced on Monday the discovery of proof of recent flowing liquid water on Mars. These findings boost the odds that there is life on the Red Planet.

A new study published in the journal Nature Geoscience reveals that Earth’s next-door neighbor has multiple dribbles of salty water that were wet, or at least damp, as recently as last year. This is not the first discovery of water on Mars. Scientists confirmed in 2008 that the Red Planet has frozen water. Now instruments aboard NASA's Mars Reconnaissance Orbiter have found the strongest evidence yet that salt water in liquid form trickles down certain Martian slopes each summer, according to the researchers.

Mars is now the only planet in our solar system to show signs of water on its surface, other than our own. "Mars is not the arid, moisture-free planet that we thought of in the past," said Jim Green, director of planetary science for NASA. "Under certain circumstances, liquid water has been found on Mars."
