Mars resembles a yet for exploring the cosmos. Only 40% of the missions on this planet are successful. The landing of the red floor is torture.
InSight, the new NASA mission, will try to support this Monday and continue the successful US agency on Mars. He will do this with a platform that has already been tested in the Phoenix mission in 2008.
The unloading will take about six minutes for NASA technicians to do nothing.
They will also learn about their progress with eight minutes of delay due to 160 million kilometers, which now divide Mars from Earth.
That would be the landing
Six minutes before arrival, InSight will enter 19,800 kilometers an hour in the Mars atmosphere. It will be 114 kilometers from the ground.
Atmospheric friction helps to reduce speed but also generates heat. The InSight thermal shield is resistant to 1500 degrees Celsius.
Once every 11 kilometers from the ground, the parachute will open. At that time the speed of the ship will be 1400 km / h.
Three minutes before landing, InSight will throw away the heat shield and place its three steps. At a speed of 215 km / h it will also separate the parachute and the rear shell. It will be one kilometer from the surface.
At that time, the 12 dropping machines will switch on to further reduce their speed. He will travel at 27 km / h and 50 meters above ground.
Fifteen seconds before, InSight will travel at 8 km / h and eventually land in a plane near the equator called Elysium Planitia.
InSight launches on May 5 this year and will work on Mars for two Earth years or a Martian year.
On the night of the red winter the temperature drops to almost 100 degrees below zero, and dusty storms often happen.
In this hostile environment, the robotic vehicle will explore the core of Mars and will seek to expand the knowledge of its formation and that of other rocky planets like Earth.
So far, missions to Mars have captured images on the surface, explored rocks, searched for clues about the water that once leaked on Mars, and even organic molecules that showed it had once been inhabited. But she has never been examined inside.
InSight will describe the size, composition and condition of the Red Planetary Cores, the characteristics of its crust and mantle, and the thermal state of its interior.
Analyze the seismic activity of the planet and the impact of the meteorites.
There is a robotic hand that will remove a few tools from the boot on the ship and put them on the Martian floor.
One of these devices has the ability to make a hole up to a depth of five meters.
