Measures to Prevent the Contamination of Mars - Universe Today
A new report from the National Academies' National Research Council says that NASA will need to be more careful to prevent Earth microbes hitching a ride on spacecraft from contaminating Mars. Recent findings show that there could be liquid water underneath the ground on Mars, and some Earth bacteria can survive in such hostile environments. According to the report, NASA is planning to implement new techniques that would reduce the risk for spacecraft flying after 2016.
