Man has always been fascinated by the planets that surround him and dominate the sky . There has always been the imagined and conjectured possibility that life may exist or could have at one time 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, unmanned probes and super telescopes have allowed him to peer at the Red Planet and learn more about its history, makeup and life . Through 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 . All of the evidence points to Mars once containing a suitable environment although that environment is longer capable of sustaining life . 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 . Mar’s color seen from Earth is a “reddish-orange” . It owes its red color to its soil, which mainly consists of iron. While the Earth travels around the sun in 365 days, Mars makes the trip in 687 days and it rotates in a similar pattern 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 surface elevation in the solar system . This is from a mountain named Olympus Mon, which is 26 kilometers tall or 16 .2 miles (Lambert). There are two moons 2

that orbit Mars, named Deimos and Phobos, which are very small . In the sky there are only a few things that are brighter than Mars, which are the Sun, Venus and the Moon (Squyres) . So the real question is, is there (or has there ever been) 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 NASA has 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
