The space probe shows that Mars is cooler inside.

Recent observations from NASA's Mars probe spacecraft show that the outermost shell and the upper shell of Mars's core are harder and colder than previously thought.

The findings hypothesize that water can exist beneath the surface of the planet and possibly underwater organisms that will be found deeper beneath the surface of Mars.

Roger Phillips at the southeastern Boulder research institute, Colombia, said: 'We have found that the hard surface layer of a star's rock is not curled if it is crushed by the north pole. This refers to the inside of the planet harder and therefore colder than we thought before. ' Phillips is the lead author of a new report that appears in the online edition of Science.

This discovery is due to the use of a Shallow Radar tool on the spacecraft that has been providing the most detailed, latest images of the inner layer of ice, sand and dust that make up the northernmost part. above Mars. Radar images reveal consecutive layers and are up to six hundred miles (1,000 km) or about one-fifth of the length of the United States.

NASA's Jeffry Plaut said, 'In our first fleeting images inside the north polar ice sheet, using radar on Mars probe spacecraft, they I can clearly see the large amount of colds showing the history of the climate on Mars. Radar opens a new path for studying Mars's past. ' Plaut is a member of the scientific team and co-author of the article.

The images from the radar show that the border line is flattened and smooth between the ice cap and the outer shell with Mars as hard as rock. On Earth, an ice sheet of the same weight can cause the earth's surface to sink. The fact that the surface of the Mars does not bend like that means that the outer shell is solid or because of the lithosphere - which is a combination of the upper shell and the upper layer which is capable of being thick and cold.

"The lithosphere is a piece of hardware ," said Suzanne Smrekar, deputy project manager for JPL's Mars Mars Spacecraft . On earth, the lithosphere is the part that cracks when an earthquake occurs. The ability to help radar can see through the ice cap and determine whether this outer shell is not curled giving us a good concept of the current daytime temperature inside Mars for the first time. '

The temperature in the outer part of the hard planet like rock is like Mars rising in parallel with the depth of the planet's inner core. The thicker the lithosphere, the higher the internal temperature. The discovery of the thicker Martian layer of lithosphere may imply that any amount of water in the hydrated part below the planet's surface may have to be deeper than it used to, it's much warmer. Scientists deduced that any life on Mars related to that deep hydration would have to lie deep inside the planet's core.

Radar images show four areas of separated ice and the outer shell separated by thick layers of pure ice. Scientists think that this thick non-frozen layer pattern represents the cycle of climate change on Mars over a period of about 1 million years. Such climate change is caused by a change in the tilt of the planet's axis of rotation and the translation of the planet's orbit around the sun. Observations support the notion that the northern tip of the ice is geologically active and relatively young at about 4 million years.

The mission of the Mars probe spacecraft is run by NASA's -Science Mission Directorate scientific mission board.
