"Since ancient time, we earthlings have believed that "Mars', the mysterious red planet carried war, pestilence and the need of human sacrifice. The Romans named 'Mars' as their 'God of war'. The mystery possessed by this planet has always ill cited the curiosity of earthlings with an imaginary belief that there also exists an alien civilization like on earth. Several movies fed on this idea, in which green Martians with head and dressing, seen trying to take over the earth”
Until the sixties, the conception of tellurians was up to the movies, picturisation or up to what the scientists could see through telescope etc. Then began the space and.’Mars' became the favorite target for scientists' curiosity. The beginning space research era helped mankind in exploring the hidden secrets of universe. USA and the erstwhile USSR, pioneered the space exploration with several oft space crafts and satellites sent on expeditions to study the Earth's atoms weather, oceans as well as Sun and other celestial bodies and planets like Moon All such expeditions brought back invaluable information’s about the evolution history of earth, Moon and other planets and celestial bodies.
'Mars' and earth has almost equal rotational period at the axis. Mars takes hours, 37 minutes, in rotating upon its axis, thus the Mars day is identical to an day. While earth takes approximately 365 days to rotate round the sun, the Mars 687 days to make such one trip, because of its eccentric orbit. The gravity of M one- third of earth's, and atmosphere at Mars is much thinner than that at earth, as the atmospheric pressure at 'Mars' is just 1 % that of earth.
