Uninhabitable Mars.So what's the point of researching if life is not possible?
There are several points to prove that Mars is uninhabitable though Mars has always held a certain fascination for humans :-
1)The lack of a magnetosphereand extremely thin atmosphere of Mars are a great challenge:the planet has little heat transfer across its surface, poor insulation against bombardment and the solar wind, and insufficient atmospheric pressure to retain water in a liquid form (water instead sublimates to gaseous state)
2)Atmospheres of Earth and Mars are radically different. In fact, if any humans set foot on the red planet, they would not be able to breathe.
3)Martian atmosphere is composed almost entirely of carbon-di-oxide(CO2), which when inhaled in large,concentrated amounts, is deadly.On Mars, the atmospheric CO2 levelis more than 95 percent, whereas on Earth it is less than 1 percent.
4)The remaining gases in the Martian atmosphere include small percentages of Nitrogen and Argon and mere traces of Oxygen and water vapour.
5)Mars has the largest dust storms in the Solar System.These can vary from a storm over a small area, to gigantic storms that cover the entire planet. They tend to occur when Mars is closest to the Sun, and have been shown to increase the global temperature.
These reasons make it utterly impossible to inhabit Mars. So what's the point of researching and investigating the Red Planet?
