Life on vitiate (Earth Science Course) - Essay ExampleSpace explorations potentiometerdid new avenues and enhanced expectations of discovery of extraterrestrial conduct. Scientists describe six basic environmental conditions suitable for evaluate life. If an environment contain all these six environmental conditions within prescribed limits then it can be expected that life may exist there. The data collected by space probes negates the presence of good life on other planets of our solar system. But the presence of primitive life in medieval on round of the planets including Mars can not be ruled out.As stated supra it is almost certain(prenominal) that no advanced life exists in the planets of solar system. But the efforts for effort for observe primitive life in our solar system are going on. It is also believed that life can come into view because of changes of natural matter from nonorganic.

Urey gave experimental aver for this assumption presented by Oparin. The similar organic activity was detected on Mars by the Viking landers in 1976. ( Exobiology. The Columbia Encyclopedia. sixth ed. 2004. )It is generally accepted that that Mars once had water, on the basis of this acceptance it is supposed that once life would have existed on the red planet in its primitive stage. Some evidences are presented in the support of this supposition in the form of reported presence of fossil bacterial life on Martian meteorite. But his evidence is not widely accepted and many scientists are of the view that it is not generous to arrive at a correct conclusion.1.4 Fossil bacterial life found on a Martian meteoriteScientists are of the view that enough evidence of microscopic bacteria fossils was found on some the meteorites fell on various countries. In France Orgeuil meteorite fell in 1864 and on some other meteorit es traces of organic material were found that indicate presence of microscopic creatures like bacteria. But another group of scientists speak out that the organic material was the result of some other factors and the evidences were not correctly interpreted. It is also not certain that these mateorits came from Mars Keeping in view all the above discussed information and interpretions, it is the primary aim this to test and discuss the possibilities of life on Mars.2. Chronological Order Famous American Scientist Sagan Edward is known for his popular probe of Radio emissions from Planets of Solar system. He was one of the first scientists made some correct predictions about Mars that were later found correct. He was instrumental in changing perception about Mars in those days.2.1 The early orbiter evidences The information acquired from the data provided by early orbiters suggests that early Mars had a raw and wet nimbus. Life can exist in such type of claim. But this type of a tmosphere must have existed in the remote past.A meteorite that was
