NASA IS SENDING COPTERS TO MARS

YES, YOU HEARD ME RIGHT! NASA is going to send a copter for mars exploration for its 2020 mars exploration in recent interviews with NASA, scientists explained this mission is not will be mainly for the space exploration but it will be our experiment for the future planes and crafts to other planets! a question must arise! why copter after the successful launch of rovers on Mars! so the answer is the copter can cover a larger distance than rovers in the particular time! and explore more.

The copter will be lifted by two propellers connected one at the top of another as the atmospheric density of Mars is very low so the copter be of lightweight !the propellers are made of carbon fiber and very thin also the gravitational pull of Mars is comparatively lesser than earth that means it has to lift only 38% of its weight. 

The copter will be completely autonomous and will be equipped with all the necessary sensors on it ! and the battery is connected in four cylindrical manner columns and it is insulated by carbon dioxide gas! giving it a total flight time of 10 to 15 min a day!

That's all!
