Evidence for AND AGAINST
How It Works UK
|Issue 210
Over the years, several clues have suggested Martian life, while other indications are against it
-
AGAINST
BARELY INSIDE THE HABITABLE ZONE
While Earth sits in the middle of the ringlike zone-around the Sun where life is theoretically possible, Mars is right on its outer edge.
AGAINST
INHOSPITABLE ENVIRONMENT
Martian surface conditions are much colder and drier than Earth's, while the very thin atmosphere shows no signs of modification by biological processes.
AGAINST
HIGH LEVELS OF RADIATION
Without the same kind of protective magnetic field as Earth, Mars is exposed to much more intense cosmic radiation - around 700 times higher than our planet.
AGAINST
TOXIC SOIL
