The Mars sensor is a challenging challenge to safely land science

NASA engineers begin their journey on Monday, which is their favorite activity in space: they are trying to calculate the robot spacecraft for Mars.

In that case, they try to place their sensor, InSight, gently forward to the Elysium Planitia area, which is to analyze seismic activity on the red planet.

More probes have been sent to Mars than any other planet of the solar system, but more than half of these tasks have ended in failure, and the final stages, which include landing gently on the Mars surface, appear to be particularly dangerous and unsuccessful.

Mars's slim atmosphere – just 1% of the Earth – means that the spacecraft has slowed down and has played a key role in past failures. Thus, the nervousness of Nasa engineers who direct their $ 800 million InSight boat after 300 million miles in a small target area in the planet's atmosphere, measuring only 15 miles 6 miles.

If InSight passes this key hole exactly, it should reach the center of Elysium Planitia even if it still needs a heat-resistant capsule, parachute, and rockets to allow its speed to fall from 12,000 to 5 meters and make sure it arrives smoothly and safely within seven minutes of deposition after.

The latest company in the port of Mars made two years ago a European probe that crashed on the surface of the planet. However, Nasa is successful.

It is hoped that InSight – an internal study using seismic studies, geodesy and heat transfer – will help scientists understand the early development of Mars and other solar systems, including the Earth, by Mars and other planets, using instruments that measure the temperature and depth of the Earth's surface seismic activity.
