Extreme Environments: Mars (2008)
Of all the planets, Mars has an environment most like Earth. For decades we have been sending probes to mars in the search for water – the essential ingredient necessary for sustaining human life on this planet. We look at the multiple missions to Mars, and the technology employed by NASA in its probes to assist with the search for water and life on Mars. Success has been a long time coming, but scientists found water in a soil sample and so were able to determine that it does indeed exist on Mars.
