Mineral Nutrients Found on Mars
U.S. scientists said soil on Mars appears to be alkaline enough to support plant life.
Samuel P. Kounaves of Tufts University said soil found by the National Aeronautics and Space Administration's Phoenix Mars lander has enough nutrients to grow a plant such as asparagus, The New York Times reported Friday.
While high levels of ultraviolet radiation and cold, dry conditions on Mars make life unlikely, the planet may have been more habitable in the past, the newspaper said.
Kounaves said the soil was similar to soil found in parts of Antarctica.
