What that touched Surface of Mars Last Thursday, until the Perseverance spacecraft, weighing 1050 kg, and costing two billion and 700 million dollars, broadcast the first image of an area of the Jesero crater where it descended to study its geological condition, and search for 687 days for any trace of life that blossomed in its environment in the distant past of the planet, because “Jezero” was 3 billion and 500 million years ago, it looked like a lake 49 km in diameter, rich in water flowing to it from two channels that appear in the pictures as a delta from a river that split into two branches.
After that, the spacecraft continued to take pictures of the surrounding area and send them to the NASA control team on the ground. These pictures are published by “Al Arabiya.net”, with an explanation contained in the US space agency website itself. As for the interesting among them, they are published 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 spacecraft appeared in it after it entered its airspace and a speed-reducing parachute drove it to its pre-prepared landing site, and led it to it by a radar installed in it.
This image, taken last Thursday by an orbiting probe orbiting at an altitude of 700 km around the planet, is the most exciting so far, and it is of a parachute that leads the craft to the landing site on the surface of the Red Planet

And the second excitement is in which the vehicle appears 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 the planet’s airspace upon its entry into it, then the canopy of 21 meters in diameter took care of it. It reached a circle of 31 square meters from the crater, prepared in advance for landing in it, separated from it and delivered it to another landing mechanism.
The other landing mechanism is a “celestial platform” known in English as the skycrane, which descends through the reverse jet, hanging from it with ropes and special wires. According to what was read by “Al Arabiya.net” on the NASA host website that the photo was taken by a camera installed in the “heavenly platform.” And transmitted it to the spacecraft when it seized the Martian nodule, 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 slow speed carriage, the parachute carried him to the pre-prepared landing area, and let him get off the vehicle and then detached from it after landing

As for the third image, it was taken by a camera in the vehicle of one of the 6 wheels, which will begin next week to roam through the promising crater, while the fourth image is for a graphic from NASA about the new navigation technology related to the terrain “to avoid risks and find a safe place to land in the Jezero crater on Mars.” Where the graphic, posted with the image of the wheel below, shows areas in blue that are safe in the crater for landing, and red areas that are not suitable, because they are rugged and thorny with pits and rocks that may interrupt the “Perseverance” wandering on Mars, which they reached after traveling 471 million kilometers in a journey that took 203 days. , At 96,000 kilometers per hour.
And NASA engineers were dazzled by the pictures
And we find in the graphic image that the landing area is colored green, according to what was 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 so far, considering that Perseverance is equipped with a technological cocktail enhanced with artificial intelligence that was not Out of the luck of any other spacecraft.

The image to the right is 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 picture, 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 carried with it for this purpose, is to search for life that may still remain a trace of it in the Red Planet, if it had a previous or present presence in it, even of a primitive microbial type, in addition to studying the geology of the planet And its climate, then collecting samples of rocks, soil and stones, for a joint mission between “NASA” and the European Space Agency, to transfer in 2031 from Mars to Earth for analysis and study in the depth it deserves.
Scientists and engineers at “NASA” were impressed by the pictures, despite their lack, and one of them is Steve Collins, an expert in steering control at the “puerperal impulse laboratory” in California, he said yesterday in a news reported by “Al Arabiya.net” as well, that it “leaves minds in a state of daze and astonishment,” adding that The US space agency “got some really cool things,” he said.
