Nasa InSight team has landed on Mars

On the surface of the planet Mars, just before 22:00, the InSight scientific vessel (NASA), the first spacecraft that reaches the red planet from the 2012.

After a 484-million-mile journey at 19,800 km an hour, InSight landed successfully, triggering festive celebrations at NASA’s premises, where everyone was excited to see if everything went well. Eventually everything went well and the boat already sent its first photo.

Approximately one meter (358 pounds) of weight, InSight is a tripod static geophysical detector, not moving like the rovers that already exist on the “red” planet. It was launched from Earth on May 5 and its destination is a vast flat area of ​​Mars, known as Elysium Planitia, 130 km long and 27 km wide, just north of the Marian Equator, also known as ” Mars “.

There, from a stationary position, InSight will begin mapping the “heart” of Mars after about three months, a period necessary to test in the meantime and put into operation its scientific instruments. Luckily for NASA, the sandstorms that swept the planet for months have now settled down and the landing area looks clear and quiet.

From the combination of the scientific data to be obtained, an outline of the evolution and the current features of the shell, mantle and core of the planet is expected to emerge, which will allow – as opposed to Earth – to draw extra conclusions about the formation and evolution of the rocky planets of our solar system. Scientists are particularly curious to know if Mars has a hot melted iron core like Earth.

It is the first seismograph placed directly on the surface of Mars and will be thousands of times more accurate than those on the Viking spacecraft in 1976. The first seismograph in another celestial body was placed on the Moon in 1969 by the Apollo 11 mission.
