In 1965, NASA (National Aeronautics and Space Administration) took our first close up picture of Mars. Since then, spacecraft voyages to Mars have revealed a world a lot like ours. (Mars Exploration Program, 1) “The planet Mars- crimson and bright, filling our telescopes with vague intimations of an almost familiar landform,” says David Grinspoon, an American space scientist. (Quotes on Mars, 1) Due to new research and technology NASA has found water on Mars and is conducting new missions to get airplanes or someday maybe even humans to Mars. Could there be life on Mars? That is the question every scientist is asking. Mars has three ingredients that scientists think is necessary for life. (Mars, 4) First, Mars has chemical elements like carbon, hydrogen, and oxygen, which are the building blocks of living things. (Mars, 4) Second, it has a source of energy, and third, it has water. (Mars, 4) Mars is more than 100 million miles away from earth. (Mars, 1) Deciding where to send a rover is not an easy job, for Mars’ exploration scientists and engineers. (Politics of Landing, 1) They have looked for sites that will help us understand Mars’ ability to support life. (Politics of Landing, 1) One way scientist tried to find life on Mars was to send the Phoenix Mars Lander mission to Mars. This mission tried to find ice on Mars, by collecting and analyzing soil samples. (Sohn, 1) The Phoenix Lander landed on Mars on May 25, 2008, close to the North Pole, where ice could be found. (Sohn, 1) Phoenix brought along ovens which allowed scientists to analyze the soil by baking it. (Sohn, 2) They could tell the types of ingredients in the soil because all ingredients melt at different temperatures. (Sohn, 2) The Phoenix found a sample that baked at 0˚ Celsius, which is the melting point of ice. (Sohn, 2) The machine also detected water vapor during the process.
