NASA is known as the leading space agency for other agencies around the world after the dissolution of the Soviet Union.
Former US President Dwight Eisenhower is one of the founders of the agency, as it was established in 1958 to be a civilian and not a military agency to advance peaceful scientific research and began working on October 1, 1958.
2-Mars or the red planet
Mars or the red planet is the fourth planet in terms of distance from the sun in the solar system and is the outer neighbor of the Earth and is classified as a rocky planet, of the group of terrestrial planets (similar to Earth). As for its name in Arabic, it is derived from the word “Amrukh” meaning the owner of red spots, and it is said Thor Amrukh, meaning it has red spots. As for Mars (in Latin: Mars), it is the name of the god that the Romans took for war. As for the nickname of the red planet, it is caused by the reddish or reddish color of the planet. Due to the high percentage of iron(III) oxide dust on its surface and in its atmosphere. The diameter of Mars is about 6,792 km (4,220 mi), which is equal to the radius of Earth and the second smallest planet in the solar system after Mercury. Its area is estimated at a quarter of the land area. Mars revolves around the sun in an orbit about 228 million km away from it, which is 1.5 times the distance between the Earth's orbit and the sun. The smooth arctic basin covers the northern hemisphere approximately 40% of the planet and may have a significant impact on the planet. Mars has two moons, the first is called Deimos, which means terror in Greek, and the second is Phobos, which means fear, and they are small and irregular in shape.

A strange image taken by the Curiosity rover since mid-2012 on the surface of Mars, and broadcast by NASA on its website last week, still baffles everyone who sees it, because it is more intriguing than any image taken by a man-made rover on the Red Planet, in which it appears a carved entrance or door Ideally in a hill, similar to the entrances to the tombs of the pharaohs in the “Valley of the Kings” near the Egyptian south of Luxor, or what we see in Al-Ula and Madain Saleh in Saudi Arabia and Jordan.
A quick glance at the image is enough to give rise to an immediate belief that it is a portal leading to a cache on Mars, or “maybe a door to another world altogether, to inspire a science fiction movie or even two,” according to a brief report on the image, published by the Australian science website ScienceAlert. As in the video below, more information. In its report on the image, the site said: “If what appears in it is not a door or an entrance, and it is certainly not a door or an entrance, so it is a fracture that resulted from a kind of pressure on a rocky shape” or an earthquake, as was recorded on the red planet on 4 This May, scientists are still working to determine its exact center.
"Science Alert" mentioned what caused the enthusiasm of the enthusiasts to be completely relieved, by saying that the rock formation similar to the door or the entrance "may appear full-size in our imagination only, because its visible height is not more than a few centimeters or inches, despite the difficulty of confirming the image that was taken of a known environment. In the name of the distinctive Greenheugh Pediment on Mars,” as he put it.
He also added that, in recent years, many people have dealt with strange and wonderful footage of Mars, including craters filled with ice, hollow rock formations, or protrusions resembling structures we know on Earth, “but the important thing is not to get carried away too much by what you suggest is not real, but merely imagination". Whoever examines the picture of the entrance may remember the ruins of Mada’in Saleh and Al-Ula in Saudi Arabia, as well as “Petra” in Jordan as well, which is real, and not from the suggestion of the imagination. As for the image from Mars, it is nothing but cracks in the rocks and ripples due to erosion. Shadows also played an important role, making the "shape" look like man-made formations on Earth.
