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 the world a step forward in finding the real truth about existing life on Mars. Hurtling in from space some 16 million years ago, a giant asteroid slammed into the surface of Mars and exploded with more power than a million hydrogen bombs. This caused huge

Plant life would be “pinned down” because of the atmospheric pressure. Within the canals of Mars, the search for Martian vegetation continues. Further more, Goldsmith 12A , scientist of astrophysics, had found oxygen and water vapor on Mars.
There is abundant evidence that Mars has “volcanism tectonism” in other words, volcanoes. A transition from a warmer earlier climate to the colder present climate may have resulted from loss of atmospheric gases to space. “Scientists believe there are volcanoes, wind-related movement of material, ice - and water - related geology.” (Dick, Steven J 119D)The average surface temperature of Mars is only about -53 C, substantially below the freezing point. Water is said to be abundant on Mars away from the polar caps however, liquid water is not stable on Mars. Although temperatures can occasionally rise above the melting point, liquid water from melting ice would quickly evaporate into the atmosphere. In addition, liquid water is the single environmental requirement thought to be essential for life. Mars still has water in the form of permafrost, water vapor, ice-soil layer, and at times, liquid water. “The network of channels on the cratered surface of Mars showed the liquid water and warm climate allowed the water to flow freely on Mars,” exclaimed Jakosky, Vuce. (7C) On August 7, 1996 the world became aware of life on Mars. President Bill Clinton announced that a meteorite found in Antarctica contains evidence of the…
