NASA is counting back to landing Mars InSight on Monday on Mars of $ 993 million, and the first to hear earthquakes and study the interior of another rock planet.
The unmanned spacecraft was launched nearly seven months ago and traveled about 482 million kilometers.
Part of his mission is to report on the efforts to send human researchers to the red planet one day, something NASA hopes to achieve in the 1930s.
The landing of Mars is the first of 2012 when the NASA Curator's expeditor landed on the surface and analyzed the rocks for signs of life that could inhabit the planet to the Earth, which is now frozen and dry.
InSight must experience the difficult entry into the atmosphere of the red planet, travel at a speed of 19,800 kilometers per hour and quickly reduce the speed to just 8 kilometers per hour.
The entry, descent, and landing phase will begin at 19:47 GMT on Monday. Almost jokingly, in NASA they refer at this stage to "six and a half minutes of horror".
Of the 43 missions fired to Mars, only 18 have reached the red planet, a success of about 40%, and all come from the United States.
"Going to Mars is very, very difficult," says Thomas Zurbuhen, an associate administrator of the NASA Missions Directorate.
"The most exciting part is that we build the successes of the best ever team on Earth – the NASA team with their performers and their collaborators."
The name InSight comes from "An Inside Study Using Seismic Research, Geodesy and Heat Transfer".
The spacecraft stops at a waist height of one meter, and after the solar panels descend, it will extend to almost 6 meters.
With the full load of fuel, InSight weighs over 360kg, almost the same as the Harley Davidson motorcycle.
Its central instrument is a seismometer for earthquake detection by the French Space Agency (CNES).
"This is NASA's only mission, which is designed around a foreign instrument," said Jean-Eve Le Gall, president of CNES.
For this reason, he added: "This is a major mission for the United States, France," and to improve the understanding of Mars.
The six earthquake sensors on board are so sensitive that they have to reveal the finest shakes on Mars, such as the weak attraction of their moon to Phobos, the impacts of the meteor and the possible evidence of volcanic activity.
Seismology has taught many people about the formation of the Earth about 4.5 billion years ago, but much of the Earth-based evidence has been lost with the recycling of the bark powered by the tectonic plate. This process does not exist on Mars.
The ship also has a sampling probe that can dig up to a depth of 3 to 5 meters to provide the first accurate measurement of the underground temperatures on Mars and the amount of heat coming out of the inside.
The landing of InSight will be replaced by a parachute. The heat shield will help delay the ship and protect itself from the friction of entering the Mars atmosphere.
The landing area is a flat area called Elysium Planitia, which NASA called "Mars's largest parking lot."
NASA will know within a few minutes whether the landing has been successful or not, but will have to wait more than five hours to confirm the deployment of the equipment. This will be at 20:04 GMT on Monday.
