NASA space robot and seven minutes of terror on Mars

Survival: NASA's space robot and seven minutes of terror on Mars


The US space agency NASA has released a new animation showing how it's one-tonne space robot (Rover) will land on the planet on February 18.


The robot, called Perseverance, has landed on a crater called Jezero, where he will search for traces of life on the planet in the past. But to do that, it has to make a very smooth landing.


The whole process of landing on Mars is also called 'Seven Minutes of Terror'.


These seven minutes are important when landing on Mars because if even a small mistake is made in this short interval, a new and very expensive new crater will appear on the surface of Mars.


This robot is self-made


The distance between Earth and Mars is 209 million kilometers and the robot is equipped with computers to run the moments seen in this animation. The landing process begins about 100 kilometers from Mars, where the rover has the opportunity to enter the planet's atmosphere.


At this time the speed of the rover is twenty thousand miles per hour.


It now has only 400 seconds to reduce that speed to one meter per second. The Hat Shield does most of the work at this stage. When the planet is in the atmosphere of Mars, its temperature is up to one thousand Celsius, which is why its landing speed decreases drastically.


By the time the supersonic parachute opens from the back of the robot, the robot's speed has dropped to 1,200 km / h. The parachute further reduces this speed.


But the hard work begins now.


When the robot is two kilometers away from the planet and is moving at a speed of 100 meters per second, the parasitic robot and the resulting 'sky crane' fall apart from each other. Then eight rockets come out of the spacecraft and take their position and the wires come out and then this multi-million dollar machine is brought to the surface of Mars.


But when the Zero Rover gets very close, it has to pull the strings attached to it, otherwise, it will be pulled by a flying sky crane. The sky crane completes its mission by moving itself to a safe distance.


The whole process is similar to the rover Curiosity sent by NASA twelve years ago, but the only difference is that this time the navigation system is much better for landing in the Zero Rover so that it can be landed in the same place as expected.


The rover, which will land on February 18, will land on Mars at 9 a.m. local time.


Remember that the radio signal that will be sent from Mars to Earth on the day of landing will arrive here seven hundred seconds later, which means that by the time NASA receives this message, the machine will have been either successful. Or it will end in a few minutes.


This rover will record everything from the camera and microphone when landing. All of these media files will be sent to NASA when the rover lands on Mars. That too in case the mission is successful.
