Astrobiologically Possible Extremophiles

. Select a specific example of an astrobiologically-relevant extremophile which you find interesting. Describe the organism and the environment in which it lives, and explain how it is able to survive in such extreme conditions. Discuss the relevance of this organism in the search for life beyond the Earth. Your answer should be approximately 500 – 1000 words in length. Be sure to cite your references

All life on earth demand a habitable condition to live, which requires an adequate amount of oxygen, water, and moderate temperatures, are fundamental for the survival of most organisms. However its completely diverse for extremophiles, they can live in a wide range of environment each having their own unique properties adapted to that particular place where they reside. There are many categories of extremophiles of which one of them are hyperthermophiles (superheat –loving) . Hyperthermophiles, particularly bacteria and archaea can survive high temperatures of 140 F or even higher. Their optimum temperature is around 80C and extends to a temperature limit of 113C(Stetter 2006).

Some of the examples of the most common hyperthermophile on earth is the

It can also help us understand the mechanisms these organisms use to survive these harsh conditions. Based on the growth requirements of pyrolous fumarii they are even able to survive on other planets such as Mars, which is the best place to search for life. Mars at the present is too cold and contains no liquid water for any hyperthermophile such as pyrolobus fumarii to survive. However, in the past Mars was certainly a place where the scientist would search for any extraterrestrial life. However, scientist still expects life to be habitable on the subsurface where there are liquid hot water and nutrients to support the life of
