Recent analyses of ESAÃ¢ÂÂs Mars Express data reveal that concentrations of water vapour and methane in the atmosphere of Mars significantly overlap. This result provides important new hints to evaluate the hypothesis of present life on the Red Planet.

PASADENA, Calif. - A patch of Martian soil analyzed by NASA's rover Spirit is so rich in silica that it may provide some of the strongest evidence yet that ancient Mars was much wetter than it is now.

If life as we know it exists on the red planet, it would have to be deeper under the surface than current probes are able to detect, a European team concludes.

An international team of scientists has found life on a Norwegian island.  No surprises there, but the successful field test of a collection of life-detection instruments may be a stepping stone for future endeavors to sniff out life on Mars.

By RANDOLPH E. SCHMID Associated Press  WASHINGTON -- An orbiting spacecraft has sent back new evidence for the presence of water on Mars.    Scientists long have debated whether water flowed on the red planet, with evidence increasing in recent years.

After studying thousands of images from Mars, scientists now are convinced that liquid water once flowed on the surface of the red planet, increasing the odds that life may have existed there in the distant past.

Scientists say there is no doubt that abundant water once soaked Mars. Now the big question is whether the red planet ever supported life. Some experts say the early signs are promising.
