IS THERE LIFE ON MARS? If you have a chance to go to a country side where you may have a clear view of the sky at night, you probably will discover a red star. That is probably Mars. With its bright and reddish color, Mars stands out for and easily noticed since the ancient times (Discovery). In 1877, astronomer Giovanni Schiaparelli discovered several crisscrossing lines on Mars that he believed to be the canals of water (Discovery).

On Earth, polar ice caps are mainly water ice, while on Mars; it is only mixture of carbon dioxide ice sublimes in summer and forms again to solid form in winter (Life). The transformation does not result to water. Idea about the existence of water on Mars is crucial to decide about the existence of life on the Red Planet. The mission of the Mars Exploration Rovers of 2004, organized by NASA, was not to look for present or past life, but for evidence of liquid water on the surface of Mars in the past (Life). In June 2000, evidence for water currently under the surface of Mars was discovered in the form of flood-like gullies (Life). Deep subsurface water deposits near the planet's liquid core might form a present-day habitat for life. However, in March 2006, there is similar discovery on the Moon, which is believed to have never had liquid water on its surface (Life). In March 2004, NASA announced that its rover Opportunity had discovered evidence that Mars was, in the ancient past, a wet planet. This has raised hopes that evidence of past life might be found on the planet today. Till now, there is no clear or strong evidence for the proven of water existence on Mars.
