Reuters, August 23rd:
The soil on Mars may contain microbial life, according to a new interpretation of data first collected more than 30 years ago.
Joop Houtkooper of the University of Giessen, Germany, said on Friday the spacecraft may in fact have found signs of a…life form based on hydrogen peroxide on the subfreezing, arid Martian surface.
“We will have to find confirmatory evidence and see what kind of microbes these are and whether they are related to terrestrial microbes. It is a possibility that life has been transported from Earth to Mars or vice versa a long time ago.”
