Since Mars is the only terrestrial planet whose surface can be directly observed in detail from the Earth with help from a telescope, it has been studied by Earth-based instruments since as early as the seventeenth century. However it is just since the exploration of Mars started in the mid-1960s that close-range observation has been conceivable. Flyby and orbital shuttles have provided information from above, while direct estimations of atmospheric conditions have been given by various landers and rovers. Advanced Earth orbital instruments today keep on providing some helpful "big picture" perceptions of moderately large weather phenomena.
Researchers imagine that 3.5 billion years back the climate on Mars was like that of early Earth: warm and wet. But because of chemical reactions between Mars ' carbon dioxide atmosphere and water, the majority of its carbon dioxide was spent forming carbonate rocks. Earth is big enough and dynamic enough that it has plate tectonics which recycles this carbonate back to carbon dioxide. Mars is too small (10 times smaller than earth) and does not have any recycling of its carbonate. So now Mars’s atmosphere is very thin, the temperature is extremely cold, and what water remains is either solidified in the Martian poles as permafrost or covered up in profound underground springs.
Mars ' current climate changes drastically during the year. It has seasons similar to the Earth 's due to the tilt of its axis .Yet, the seasons vary in length…
