Man has always been fascinated by the planets that surround us and dominate the sky . There has always been the imagined and conjectured possibility that life may exist or have existed on Mars . This has led to extensive writing, research and theories on the possibilities for life beyond our own small planet . As man has developed the scientific method and begun to explore the heavens, advancements like space travel and super telescopes have allowed us to peer at the Red Planet and learn more about it's history, makeup and life . Through the scientific data that has been compiled about Mars, there is reason to believe that life existed on Mars at some period in the past but there are probably no living organisms on the planet today . Mars is the fourth planet from the sun and lies between Earth and Jupiter . It is believed to be about 4 .6 billion years old, which is the same age as the Earth. It received its name from the Roman god of war . The Romans affiliated the god of war with Mars because the redness of the planet reminded them of blood . Mars color seen from earth is a “reddish-orange” . It owes its colors its soil, which is mainly consisting of iron. While the Earth travels around the sun in 365 days it takes Mars 687 days and it rotates similar to Earth on its axis from west to east . It also is different from the Earth in temperature with an average of -80 degrees Fahrenheit (Squyres) . Mars also has the highest elevation in the solar system . It is from a mountain named Olympus Mon, which is 26 kilometers tall or 16 .2 miles (Lambert). There are two moons that orbit Mars names Deimos and 2

Phobos, which are very small . In the sky there are only a few things that are brighter then Mars, which are the Sun, Venus and the Moon (Squyres) . So the real question is, is there (or was there) life on Mars? While no man has ever landed on the red planet, there have still been many pictures taken by telescopes on earth, probes flying past it, and recently robots that they have landed on the Martian surface . Steven Squyres of NASA said, “Mars almost certainly has three ingredients that scientists believe are necessary for life: (1) chemical elements such as carbon, hydrogen, oxygen, and nitrogen that form the building blocks of living things, (2) a source of energy that living organisms can use, and (3) liquid water” (Sec . Possibility of Life). On August 7, 1996, a press conference was held to announce that scientists had found evidence of life in a meteorite that crashed in Antarctica thirteen thousand years ago . The meteorite was found in 1984 but was only confirmed to be from Mars in 1993 . Scientists call it ALH 84001 and it is one of the biggest pieces of evidence for the belief that life did in
