Mars Surface

The surface of March is a dry, barren wastelle characterized by ancient volcanoes and craters. You can wash the entire surface with a sandstorm and you can hide it for several days at a time. Despite enormous conditions, scientists are more likely to understand the surface of March than any other solar system, except for our own planet.

Mars is a small world. Its radius is half of the earth, its mass is less than 1 / 10th. The total surface area of ​​the red planet is about 28% of the earth. I do not think this is like a big world, but it is almost equal to all the arid lands on Earth. The surface is thought to be mainly basalt, covered with a fine layer of iron oxide powder and has consistency of talc. Iron oxide (commonly known as rust) gives a characteristic red coloration to the planet

In the ancient past of this planet, the volcano erupted without decreasing for millions of years. Because of the absence of plate tectonics on Mars, lava can be poured on the surface for thousands of years at a single hot spot. The absence of a structure means that the same cracks on the surface will remain open until the pressure to push the magma onto the surface no longer exceeds. Olympus is formed in this way and is the largest mountain in the solar system. It is 3 times higher than the mountain. Everest These uncontrollable volcanic activities can also partially explain the deepest valleys of the solar system. Valles Marineris is believed to be the result of material collapse between two hot spots and substances on Mars.

The surface of Mars is dotted with craters. Since there are no environmental factors that can erode them, most of these craters are still intact. The planet lacks wind, rain and plate tectonics, causing erosion on the earth. Since the atmosphere is much thinner than the Earth, smaller meteorites can affect the Earth.

The surface of March is considered to be very different from the surface billions of years ago. The data returned by rovers and orbital athletes shows that there are many minerals and erosion patterns on the earth that indicate past liquid water. It may be that small seas and long rivers dominated the terrain. The last trace amount of water is trapped in water ice under the water. Scientists want to discover the treasures of Mars by analyzing the ice

Finally, if you want to learn more about Mars, we created several podcasts on Red Planet with astronomical casts. Story 52: Mars, episode 91: find the water of Mars

Mars is the focal point of many scientific studies on the possibility of human colonization. The surface condition of Mars and the presence of water in the past make it the most kind planet in the solar system except the earth. In addition to Venus, Mars requires less energy per unit mass (delta-v) than any other planet. Permanent human settlement on other planets including Mars is one of the most popular themes in science fiction. As technology advances, human concern about the future of the planet is rising, and debate over space colonization is gaining momentum. Other reasons for colonial space include economic benefits, long-term scientific research on humans, not being robotic detection, and pure curiosity.

Humanity has brought a huge engineering challenge to the mission of Mars. Since the surface of Mars contains superoxide, there is no magnetic layer and ozone layer to prevent solar radiation, so scientists fully understand the dynamics of Mars before human behavior takes action to enter Mars Have to. Historically, the NASA mission of Mars mission has the highest failure rate, and it can be attributed to the huge engineering challenge and some bad luck of these missions. Many of the objectives of the Ministry of Environmental Protection include the entry of spacecraft (EDL) onto the Martian surface, falling and landing, such as planetary atmosphere, heterogeneous terrain, and high testing costs for the environment reproducing Mars .
