Life On Mars Life on Mars If life ever evolved on any of the other planets, Mars is the likeliest candidate. After Earth, Mars is the planet with the most hospitable climate in the solar system. So hospitable that it may once have inhabited primitive, bacteria-like life. Outflow channels and other geologic features provide extensive evidence that billions of years ago liquid water flowed on the surface of Mars. Continuing changes is an accomplishment in modern American technology and it gives th
