Mars weather is extremely harsh

Scientists at the US Aeronautics Agency (NASA) identify the weather on Mars extremely harsh. How harsh is the red planet?

'Mars is as cold as hell', singer Elton John lifted the forecast of such a Martian climate in the Rocket Man song released in 1972 - four years before the landing of the Viking 2 landing gear. first safe down to Mars surface in 1976.

And most recently in August 2012, images of the Martian surface were sent by NASA's Curious probe to Earth with beautiful red-brown rocks but in fact it was very dry. and cold.

Scientist Jeffrey Marlow, working on the Mars Exploration Program (NASA) wrote on his personal blog: 'The temperature of the Martian air ranges from -75 degrees Celsius at night and to about 0 degrees Celsius. noonday. In addition, Mars 'atmosphere is very thin and there is little water vapor.'

Mars only receives about 50% of sunlight compared to Earth, the Martian atmosphere is sparse about 1%, and the night is as cold as cutting the same skin in the Arctic Earth.

'We do not expect the Curious ship to find liquid water on Mars, because it will evaporate and re-freeze very quickly. With too little water vapor in the atmosphere, any liquid water molecule on the surface will turn into gaseous form , "said Ashwin Vasavada, deputy project manager at Mars Science Laboratory (NASA). know.

'So while on Mars, drinking coffee will happen quickly. In the Gale crater area - the Curious ship's landing position - though it looks like an area in southwestern America, but when you look at a thermometer, force you to immediately search for your jacket. winter ' , Mr. Vasavada added.

Elsewhere, NASA scientists were puzzled recently when the ship's Opportunity probe - landed on the surface of Mars in 2004 - sent to Earth an image of marble spheres lying dense in the cliff area near the western crater Endeavor is the largest on Mars.

They say the structure of these spheres is like blueberries, thought to be formed millions of years ago when the red planet was warm enough to store liquid water.

Similar spheres have also been found in sandstone in the southwestern United States, so some scientists think this is a clue to finding the life of microorganisms on Mars.

But when Opportunity uses X-ray spectroscopy to analyze the structure of the above stone sphere, it does not "taste" the taste as when eating blueberries.

'Non-iron, seemingly crunchy orbs in the middle and softer in the middle' , said lead researcher Steve Squyres of Opportunity data, working at Cornell University (USA).

'They (stone balls and blueberries) differ in concentration, structure, composition and distribution. So the geological mysteries on Mars are waiting for us to explore , 'Mr. Squyres said.

Fortunately, Opportunity ships are still in good working condition. Now, it needs to be strengthened with 'fruit juice drink' to continue studying other mysterious orbs on Mars in the future.
