The Phoenix spacecraft has found a substance in the Martian soil that might be detrimental to possible life, scientists reported Monday. If confirmed, it could mean the soil may not be as friendly as once thought. Scientists previously reported that the soil where Phoenix landed in May was Earth-like, containing nutrients such as magnesium, sodium and chloride, however the latest lab tests show the presence of an oxidizing substance. NASA was investigating whether the substance could have gotten there by contamination.
