As soon as I touched the surface of Mars last Thursday, the Perseverance spacecraft, weighing 1050 kg and costing two billion and 700 million dollars, released the first image of an area of the Jesero crater where it landed to study. its geological condition. , and search for 687 days any trace of life that flourished in its environment in the distant past of the planet, because “Jizero” was 3 billion and 500 million years ago, like a lake 49 km in diameter, rich in water that It flows into two channels that appear in the images as a delta of a river that divides into two branches.
After that, the spacecraft continued to take photographs of the surrounding area and send them to NASA’s ground control team. These photographs are published by “Al Arabiya.net” with an explanation contained on the website of the US space agency. As for the interesting ones among them, they are posted below. They were picked up by a probe launched by NASA called the Mars Reconnaissance Orbiter, which has been circling since 2006 around Mars. The craft appeared on him after entering his airspace and a speed reducer parachute drove him to his pre-prepared landing site, and guided him by radar installed on him.
This image, which was taken last Thursday by an orbiter orbiting at an altitude of 700 km around the planet, is the most exciting so far, and it is of a parachute that takes the spacecraft to the landing site on the surface of the Red planet.
And the second emotion is that the vehicle seems to have landed on the planet’s skin, after it separated from what they call the “heat shield” or the heat shield designed to protect it from the high temperatures caused by friction with space. aerial of the planet. her entrance into it, then the 21 meter diameter dome took care of her, she came to a 31 square meter circle from the crater, prepared in advance to land on it, separated from it and handed it over to another landing mechanism .
The other landing mechanism is a “sky platform” known in English as a skycrane, which descends through the reverse jet, hanging from it with special ropes and cables. As read by “Al Arabiya.net” on the NASA host website that the photo was taken by a camera installed on the “heavenly platform”. And he transmitted it to the spacecraft when he seized the Martian node, and in turn the spacecraft sent it to Earth, and then separated from it “the platform” to be destroyed elsewhere.
The image of the vehicle after its landing, was taken by a camera installed in a low speed controller, the parachute took it to the landing zone previously prepared, and allowed it to get off the vehicle and then take off from it after landing.
As for the third image, it was taken by a camera on the one of the 6-wheelers, which will begin roaming the promising crater next week, while the fourth image is for a NASA graphic on the new technology. related navigation. to the ground “to avoid risks and find a safe place to land in the Jezero crater on Mars.” Where the graphic, published with the image of the wheel below, shows areas in blue that are safe in the crater to land on, and in red areas that are not suitable, because they are steep and thorny with holes and rocks that can interrupt the ” Perseverance “roaming Mars, which they reached after traveling 471 million kilometers in a journey that lasted 203 days, at 96,000 km / h.
And NASA engineers were dazzled by the images.
And we find in the graphic image that the landing zone is colored green, as distinguished by a report from the “Jet Propulsion Laboratory”, the most sophisticated and sophisticated among the most sophisticated and complex missions that NASA has carried out on Mars. missions thus far, keeping in mind that Perseverance is equipped with an artificial intelligence-enhanced tech cocktail that was not out of the luck of any other spacecraft.
The image on the right is from radar, where the areas that are not suitable for landing in the crater are rocks in red, while the blue ones are valid, and in a circle of 31 square meters, prepared in advance, the vehicle landed. As for the second image, the vehicle sent it to one of its wheels.
The summary of the mission, which includes the flight of a small helicopter in the atmosphere of Mars, which the vehicle took with it for this purpose, is to search for life that may still be traced on the Red Planet, if it had a presence. previous or present in it, even of a primitive microbial type, in addition to studying the geology of the planet and its climate, to later collect samples of rocks, soil and stones, for a joint mission between “NASA” and the Europeans. Space Agency, to move in 2031 from Mars to Earth for its analysis and study in the depth it deserves.
Scientists and engineers at “NASA” were impressed with the images, despite their scarcity, and one of them is Steve Collins, an expert in steering control at the “puerperal impulse laboratory” in California, said yesterday in a news story. reported by “Al”. Arabiya.net “too, which” leaves minds in a daze and awe “, adding that the US space agency” got some really cool stuff, “he said.
