Mars? Why not build a foundation on the Moon? Some questioned. In fact, we know it better and closer to the Earth. The Moon is spring to other celestial bodies. In addition, we use it as a gravity ramp to accelerate and save fuel with space savers.
The man visited the Moon in the sixties and seventies. And the astronaute returned home safely and firmly. And without the Apollo tours, we would never be quiet to dream InSight.
InSight was launched on May 5, 2018, with an Atlas rocket, from California. It was landed yesterday on November 26 at Elysée Plain, on Mars, after seven years of work and seven months of space travel.
The excitement and excitement overflowed the NASA Jet Propulsion Laboratory control center in Pasadena, California. So they live in the historical achievement.
The process was perfect: the operation of the parachute, the use of its legs and the speed reduction of 19,800 km / h to 8 km / h in just seven minutes.
The mission will last a little more than one year of Martian (about 2 years in the Earth); 708 lunchtimes, or 728 days of Earth.
Journey to the past
The curiosity and interesting to know how Mars is huge. The more we know about Mars, the more we understand our Earth. We already know a lot about our solar system, but not about forming the planets. "We believe that heat occurs when gas and dust conflicts in the solar system, forming a planet thanks to the severity of force. So much heat the planet melts," explains Suzanne Smrekar, deputy director of InSight mission research projects.
"The Earth and Mars are two rocky plants that arise at the same time"

Then, "the planet cools and crystals begin to form," Smrekar adds. The hottest materials are zinc and form the planet's mantle. Iron and nickel form a metallic core, whereas the lighter material equates to a basic rash. These are basic structures shared by rocky planets, such as Earth and Mars. However, their layers, the mantles and the cores have a different chemical composition. Here are the layers that InSight will investigate on Mars.
Take a Mars bully
The Moon has revealed some, but not all, secrets about the progress of the planets. "The pressure and internal temperatures of the Moon are not as high as on Earth and Mars," said Smrekar.
InSight will measure the thermal productivity of the red planet with a "heat heater search" and record the movements of the tectonic plates, as well as other seismic activities. The search will also check the extent to which Pole North Martian moves while Mars marches the Sun. In this way, researchers want to find out if Mars's core is liquid and if it contains metal other than iron.
"The Earth and Mars are two rocky plants that emerged at the same time," explains Annick Sylvestre-Baron, deputy head of the project, which adds " although the Earth is still alive, Mars became a desert ice cream about 3,500 million years ago ". The CNES French seismic measurement system will take Mars pulse. And the HP3 heating auditor, developed by the German Aerospace Center (DLR), will do the same. HP3 will penetrate approximately 5 meters from the Mediterranean soil.
"Humanity needs to know where it's come out and where it goes," ends Sylvestre-Baron. So, if everything works, InSight can learn more about our solar system and reveal secrets about life on Earth.
