Mars: ‘7-minute terror’ of robots in search of life on the red planet

In that seven-minute interval, the area known as Zenero Crater would move at the top of the Marshall atmosphere at a speed of 19,500 km / h, in a time of about 3 km / h at the time of landing.

The robot of perseverance arrives at its final destination, Mars, where it is scheduled to arrive on February 18, 2021.

In this animation just delivered by NASA (US Space Agency), you will be able to see what a “seven-minute panic” would be, which would finalize the expected arrival on the Red Planet.

During that time, the strength will go at a speed of 19,500 km / h, which is at the top of the martyr’s atmosphere, known as the Jjaro crater.

One day, a robot would look for signs of microscopic life on the planet for at least one year on Mars (about 687 Earth days).

The Persistence Vehicle will collect rock and soil samples, store them in a tube, and leave them on the planet’s surface for future transfer to Earth.

The robot will also study the geology of the red planet and test ways in which astronauts in future missions can produce oxygen from CO2 in the atmosphere to breathe and use it as fuel.

“Seven Minutes of Terror”

The sequence of complex maneuvers that take place before the landing of the fortress has already been described by many experts as “seven minutes of terror”.

In July 2020, a robot leaving Earth will travel encapsulated in a two-piece box: a rear shield and a thermal shield.

As the spacecraft passes through the atmosphere of Mars, its heat shield will face temperatures up to 2,100 ° C.

When it is about 11 km from the ground, the spacecraft will launch a parachute that will reduce the vehicle’s speed from 2,099 km / h to about 320 km / h.

Then the heat shield will separate from the back cover and the robot will fall freely to the ground for a short time.

Eight retrofogets will then be activated, enabling the “Celestial Crane” maneuver, through which the fixture will slowly descend with three nylon wires and one “ribbon”.

When the explorer’s wheels touch the ground, he will let go of those connections.

This is the first NASA mission to directly search for “signatures” or biological signs of life since the Viking project in the 1970s.
