The atmosphere of Mars is totally alien



Mars is considered as the favorite human place for living in future.  Mankind is seeing Mars as the next great journey into space. Our adjacent Red Planet has numerous weather and climate distinctiveness that formulate it a perilous place for humans, but it also has an abundance of belongings that familiar with our home planet to make it an attractive, although challenging, target.

Sun is more far from Mars than Earth, approximately 142 million miles vs. our 93 million miles. The days of Earth and Mars are almost equivalent — one Martian soil is about 24½ hours. Mars takes 687 days to revolve around the sun. The planetary axis of Mars is tilted about 25 degrees, alike to Earth’s tilt, but its orbit is extra oval than Earth so its seasons are about double as long.

The environment on Mars is tremendously slight. The atmosphere of Mars contains about 95 percent carbon dioxide. The regular atmospheric pressure on Mars is around 7.5 millibars, is compared to 1,013 millibars on Earth. The planet also showers harmful radiations. These are the characteristics which differentiate extraterrestrial weather from ours and no human can survive on it devoid of a proper space outfit or a strongly restricted ecological habitat.

Our neighboring planet, Mars is an enormously cold planet with a standard temperature around minus-80 degrees. Heat can dip to minus-225 degrees around the poles. The epoch of heat is concise. Elevation can reach 70 degrees for a succinct time around Noon at the equator in the summer.

Rain hasn’t happened for millions of years then there’s no need to worry about rain on Mars. With only little amounts of water vapor, the planet is a dehydrated and deserted place. Clouds do form, but they are extremely high in the sky and at the surface, where mist and fog forms as a result of the very steep lapse rates near the ground.

In the high poles and latitudes, snow is a possible phenomenon but it is not like the snow on earth. In September 2012, NASA’s Mars Reconnaissance Orbiter identified that snow which is made up of carbon dioxide, falling near the South Pole. It is always known by the Scientists that there are ice caps on Mars. Now the new findings identified and observations suggested that it can be possible that these continued ice caps maybe the snowfall itself.

The whole planet contains a diversity of temperature because equator is too hot while poles are enormously cool which end up driving high wind speeds. Low-pressure systems can form and polar fronts develop at the southern end of the polar ice cap, especially at the period of seasonal alteration.

Winds pick up fine dirt particles which form gigantic dust storms which encloses much of the planet. Heated dust particles can ascend to over 20 miles above the surface. Wind rapidity can reach 60 miles per hour or more in these storms. Dust devils have also been pictured by satellite and telescope. It is estimated that several of these cyclones can be up to 30 miles in diameter.
