Clues to Mars life may lie underground: Scientist
Clues to Mars life may lie underground: Scientist:
"Houston, Mar 17: To learn if Mars ever supported life, researchers should look underground, a scientist presenting results of the Mars Express mission said at a conference this week.
The European Space Agency's orbiter has mapped almost the entire planet for minerals that bear chemical fingerprints of past encounters with water.
Less than 1 percent of the planet's surface bears signs of hydrated minerals, said Jean-Pierre Bibring, the lead investigator for the Mars Express Omega instrument, which splits and analyzes visible and near-infrared light radiating from the planet's surface. "
