EXOBIOLOGY: THE SURVIVAL ABILITY OF HALOPHILES UNDER MARTIAN CONDITIONS
The recently developed Odyssey gamma-ray spectrometer (GRS) has detected high concentrations of hydrogen, which strongly indicates there is permafrost and water ice in the upper meter of soil in the South Pole region of Mars. This finding presents the possibility that halophilic (salt loving) Archea...
