NASA is in the countdown to landing & # 39; Mars probe Mars Insight, something that will take place on Monday. The probe cost was & # 39; 993 million dollars and is the first that can & # 39; listen & # 39; earthquakes and study the internal functioning of & # 39; other rocky planet.
The unmanned spacecraft was launched nearly seven & # 39; months ago and traveled about 482 million kilometers.
Part of its mission is to transmit information to send human explorers to the red planet one day, something that NASA hopes to obtain in the 2030s.
The landing probe on Mars is the first since 2012, when the explorer of Curiosity of landed NASA on the surface and analyzed rock for life signs were resided next planet to world, now cold and dry.
Insight to save the difficult entry into the atmosphere of the red planet: currently traveling with & # 39; speed & # 39; 19,800 kilometers per hour and once it will reduce it quickly for 8 kilometers in just one hour.

The entry phase, descent and landing will begin at 17: 47 & # 39; on Monday (local time). NASA suggests that stage as "six and a half minutes of & # 39; terror".
Of the 43 missions launched in & # 39; Mars, only 18 reached the red planet, a & # 39; & # 39 success rate; about 40%, and all came from the United States.
"The go to Mars is very, very difficult", said Thomas Zurbuchen, associate administrator of the Science Directorate of NASA missions.
The name Insight translates to "domestic exploration" referring to seismic investigations, geodesy and heat transport.
With full fuel load, Insight weighs more than 360 kg, almost the same as Harley-Davidson motorcycle. If you use your solar panels can & # 39; measuring nearly six meters.
Its central instrument is sismometru of & # 39; detection & # 39; earthquakes made by the French Space Agency (CNES).
"This is the only NASA mission that is created around an instrument made from overseas," said Jean-Yves Le Gall, president of CNES, to AFP.
Therefore, he added that "it is a fundamental task for both the US as well as France," because it allows a better understanding Mars.
The six earthquake sensors on board are so sensitive to reveal smaller tremors on Mars, such as weak pull their Phobos moon, the impacts of meteors and possibly evidence of & # 39; volcanic activity.
The ship also has a probe that automatically marks allowing drilling to a depth of & # 39; 3 to 5 meters, and will enable the realization of & # 39; the first accurate measurement of the temperatures of & # 39; underground f & # 39; Mars as well as the amount of & # 39; heat escaping from inside
Care & # 39; landing.
The Insight will be tempered by a parachute landing that allows unmanned spacecraft speed will drop to 19,800 kilometers. Its thermal shield helps to reduce ship and protect him against the friction will generate its revenues in the atmosphere of the red planet.
The landing site will be in & # 39; flat area called Elysium Planitia, which NASA described as "the largest park on Mars".
The agency & # 39; space & # 39; US know f & # 39; material & # 39; minutes if the landing was a & # 39; successful or not, but must wait more than five hours to confirm that the unmanned spacecraft could use the equipment without inconvenience.
They will look for signs of life on the red planet
NASA spacecraft, which will begin in 2020, will look for clues about whether there ever was life on Mars by analyzing the rock & # 39; ancient lake and delta, two geographic features that can preserve signs of & # 39; ancient organisms, reported a few days ago the American space agency.
The ship will land on the krater b & # 39; diameter & # 39; 45 km, was once the home of & # 39; river, so could & # 39; & # 39 preserva signs; organic molecules and microbes, explained the expert.
