Unveiling the Desert
 The Atacama Desert in northern Chile is the driest place on planet Earth. It extends from just below the border between Chile, Peru up to 30 degrees south, about 240 kilometers north of Santiago. The average rainfall is recorded in be.04 cm per year, which essentially means it never rains. The Sahara is almost.8 inches, while the Gobi desert sees a huge 7.6 cm per year. So what makes a desert a desert? Typically, a desert is defined as a region that receives less than 10 inches of rain a year, so that we can be sure that the measures of Atacama, and that, by definition, many of the deserts in the world, you probably do not even compare drought in this desolate region in Chile so why would anyone want to go there? Well, for starters, is absolutely beautiful and rare, its climate makes it one of the most unique landscapes in the world. Watching the sunset from the Valley of the Moon, standing on a giant sand dune, overlooking distant volcanoes and a lunar landscape, surreal, Atacama is really a travel destination need Chile. The thought of being between 10 and 15 million years, the Atacama desert in addition to the title of world's driest desert, is also the oldest desert in the world. Scientists are very interested in Atacama, in order to consider how little life needs water to survive. In fact, much of what they are learning in their studies of the Atacama is on questions about life on Mars and other distant planets. During a trip to Mars is too expensive and very unlikely for the moment, driving in the Atacama Desert is a useful and practical compromise. There are two important features of the climate on Mars. It 's very dry, but also is very, very cold. This means that water would exist in the form of ice. Although the Atacama is very dry from the perspective of the Earth, still does not compare with the aridity of Mars today. What the scientists believe, however, is that once Mars had water flowing on the surface, much the way the Earth today. They see evidence of hives, the polar ice caps, and the spectroscopic measurement, which is the study of the interaction between radiation and matter. So scientists are studying the survival of life in the Atacama desert, in order to relate to the possibility that life existed on Mars before it basically froze. common model for example, has the ability to survive with little, sucking even the slightest moisture from the air. Mold is not quite as interesting as the image of alien life we like to evoke in our minds, but the point is mainly that it's a start. So far they have not discovered much of Atacama. There is a strong presence of nitrate, which accumulates on the rocks of the desert for a long period of time in the desert. If there were bacteria present, and other life forms, would be using the nitrate, preventing accumulation. They found some land and oxidant are focusing much of their attention on these. They will continue to use as an outdoor laboratory Atacama despite its weak relationship with the conditions on Mars. Is there really no other place in the world is approaching. So if you're interested in traveling to another planet, and you're not an astronaut, you just might find some of what you're looking for in the Atacama Desert. It may be no rain, but it certainly is not devoid of beauty.
