Document Summary
Methane on mars is plausible evidence of life on mars. Something, at one point in time, will ruin our earth as we know it. Even though mars is much smaller, it"s land area is comparable to earth"s due to how much of earth is covered by water. Mars is relatively far from the sun, much colder than earth, This could be xed by adding greenhouse gases to the atmosphere. Mars is half the diameter of earth. Surface gravity of mars is substantially less than earth; very thin atmosphere due to this. 90% carbon dioxide, much too thin and not breathable. Its 250,000,000 miles away from our earth. 1/2 of the space probe that have been sent to mars have failed. Humans should be on mars by 2040. Mars used to be covered in water. To form a colony on mars we would need:
