Possible that there is liquid nitrogen close to the surface of the red planet . potassium perchlorate has been found in the soil , which exceeds the freezing point so the water does not dissolve into ice , but is liquid . such as we know it is ' not likely ' to survive due to earth 's harsh conditions . Finding could make it easier for humans to survive on Mars in the future .
Possible that there is liquid water close to the surface of the red planet . Substance perchlorate has been found in the soil , which lowers the freezing point so the water does not freeze into ice , but is liquid . Life as we know it is 'not likely ' to exist due to planet 's harsh conditions . Finding could make it easier for humans to live on Mars in the future .
