InSight (2): will be used to study the earthquakes and the subsoil of Mars
Last phase of the mission started 7 years ago and cost 850 million dollars
NASA's InSight mission began on May 5th, when the Atlas V carrier rocket was launched from the Vandenberg AFB, carrying the probe destined to land tonight. Italian on the surface of Mars. After seven years of work and costing about $ 850 million, today in seven minutes the fate of this mission will be decided to study the seismic activity of Mars as the probe will proceed to the complicated entry into the very rarefied Martian atmosphere, which offers less resistance to slow down the descent. NASA has studied -as in every occasion- in the smallest details the landing of the probe that from 20.40 to 20.53 will complete the approach on the ground, "helped" by a sensor necessary to calculate the orientation that was built in Italy.
If everything should go as expected, the InSight mission will begin its operational phase by installing a seismometer and inserting a thermal sensor into the Mars subsoil, through which the internal temperature and the heat flows of the "red plant" will be measured. The goal of the probe built by Lockheed Martin will be to provide NASA researchers with data on the depths of Mars, in the hope of being able to know how the rocky planets of the solar system were formed.
