Giant Mars rover will search for life |
Washington DC - NASA will search for signs of life on Mars with a giant rover due to launch in 2009. The agency selected the vital instruments that the Mars Science Laboratory rover will carry on Tuesday.
Scientists have long debated whether life ever blossomed on our neighbouring planet. NASA's twin Viking landers beamed back contradictory evidence for biological activity after they touched down in 1976. But since then, the agency has not searched directly for signs of life but for the conditions and substances that support it, such as water.
