Fourth Rock From the Sun

             The fourth rock form the Sun is also known as Mars. Mars is a dead barren planet, but when the past comes alive anything is possible. It's believed that at one time on Mars a thick nitrogen atmosphere was present with fresh running water, but was that enough to sustain life? If so did life on Earth become created from life on Mars?
             Mars today is the dull red planet. We have spent billions of dollars launching probes and unmanned missions in the search for life in our Universe. What we have researched the most about Mars is the chemical makeup, which is three times the amount of sulfur, two times the carbon-dioxide, much less nitrogen, and a density of about 3.5 meaning the planet has a small inner core and more alloys then metals. The sulfur is what gives the planet the red tint. The temperature of the red planet is about -80 F around the equator and closer to -100 F at the polar caps. There are many interesting physical features on Mars as well such as Mt. Olympus which is the largest mountain in the Universe reaching 12 Kilometers, and also the Trench of the Mariners. The Trench of the Mariners is our Grand Canyon but twice as deep and would run from L.A. to Washington D.C. if in the same place as the Grand Canyon in the United States. Mars also has polar ice caps much like those of Earth. Mt. Olympus is a shield volcano just like what is found on Earth. The ones on Mars have the chemical make up of H2O, and just like on Earth it is frozen solid. Mars also has what looks like river beds running throughout the plains. Pictures of the planet look like a very cold desert stretching across the hillside. But the question still remains, was it always like this?
             One of the greatest discoveries of Mars didn't come from any mission to Mars but instead from the most unlikely of a place. The greatest discovery came from Antarctica. In Antarctica a meteorite hit called ALH84001. This meteorite was shot into orb...
