Searching for Mars on Earth
On Mars , the grounds for life could be concealed in rock that resemble some of Earth ’s most utmost environment . Scientists from the SETI Institute will pass five age exploring these strange geologic sites to learn where and how to seem for life . Chile ’s Licancabur volcano , come across here , had a UV power of 43 record in 2003 . The level is more similar to surface radiation sickness on Mars than typical shape on Earth .
Lastarria volcano
Lastarria volcano in Chile is one of the few places on Earth where liquified sulfur freely period .
Molten sulfur
Sulfur beleaguer a steaming vent , or fumarole , at Lastarria volcano .
Australia’s red rocks
Some of Earth ’s oldest fossils come along in Western Australia ’s Pilbara region . depend for signs of life here could lead scientist to alike rock candy on Mars .
Ancient life
A Pilbara stromatolite . The dark bands are fossilise microbes . Layer by layer , mats of bug trapped and built up rock music - alike mounds of sediment 3.45 billion age ago .
Survivors
Stromatolites in Sharks Bay , Australia , one of the few places on Earth where these survive fossils subsist .
Cold and wet
On Axel Heiberg Island in the Canadian Arctic , salty springiness flow twelvemonth - round .
Hardy microbes
unfearing , inhuman - sleep together microbes thrive in the insensate and west surroundings , which may mimic conditions on ancient Mars . Here , green cyanobacteria have colonize a rock from Axel Heiberg Island .
The right brew
Some scientists think sprightliness may have started on Earth at hydrothermal vents in the ocean , where a robust chemical soup spews from the seafloor . THe SETI researchers will test different method for encounter hydrothermal deposits on Mars .
