The first Mars core map highlights the big differences of the Red Planet with Earth.0: 00/5: 03 namsao fire with thin shell, coating and thick core. Photo: Naspassy Nasac and the National Universe (NASA) have announced the first detailed map of Mars in the internal structure based on data collected by the Insight exploration ship. The results show that the inner structure of Mars and Earth has a big difference. NASA's Mars Insight explorer is responsible for collecting data on Mars
. The three new articles are published in Science magazine using data collected by Insight to conduct a deep analysis of Mars's geological structure. This is the first time people get the core structure map of other planets. The newspaper indicates that the entire Mars is like a variety of candies
The shell divided into two to three layers by volcanic rock like chocolate. The coating of the fire is like a hard candy. The core of Mars is lighter, especially the exterior core like the Siro.con who has studied the inner structure of the planets for a long time. In 1889, humanity first discovered the hard and thick layer and the soft layer soft of the earth coating. Later, in 1914, scientists have identified the core outside the liquid and the inside of the Earth's snake. The person who is also conducting similar exploration activities on Mars. Paula Koeleeijer, seismic house at Royal Holloway University, said that this study uses the most advanced seismic measurement technology ever and shows "a big step in planetary seismic". Nasa's Insight exploration ship initially the initial research tasks only estimate the size and characteristics of the structure inside Mars. However, NASA's Insight exploration ship uses a robot arm to install a small seismic meter on the Mars surface to help analyze the internal structure of Mars more accurately
Scientists can use seismic data collected by Insight to simulate the evolution of Mars.Insight will also help scientists study other planets. Mark Panning, a scheme of planetary planets at NASA's jet push laboratory and the co-author of the article said: "If you are a doctor and only perform surgeries for a patient, You will not be a good doctor ".christine houser, seismic house at the Academy of Earth Life Sciences in Tokyo, Japan said:" Chemical evidence shows Mars like their cousins We are rather than the sibling meat. It is really an ancient relic that exists in the solar system. "Insight boat is equipped with enough models to collect data about the smallest activities on Mars. Sounds, supershocks about this earthquake named SOL 128. Most seismic seisms of Mars occur in surface layers. But some come from deeper places and spread many times inside Mars before reaching Insight's position. Speed and direction of shock waves will change when they move through different material layers, so scientists can use these deep shocks to understand the internal structure of Mars. Article This is not easy. A seismic meter means that scientists can only observe a single area on Mars, not the entire planet. Moreover, to build a detailed map of the internal structure of Mars, the most ideally can detect a large number of strong seismic battles going through the entire planet. But the seismic intensity on Mars has never exceeded 4.0 Richter. Very challenging challenges, the scientists finally confirmed that the same as the earth, inside Mars 3 layers - the shell , Coating and core. However, the size and composition of these classes in Mars and Earth have a significant difference. The average thickness of the Mars shell is between 24 and 72 km. Meanwhile, the earth's crust has a maximum depth of about 100km. Mars shells may have three layers, the above layers are mainly volcanic rocks due to colliding with meteors, the middle layer is more adhesive volcanic rocks. Scientists have not been able to determine the structure characteristics of the lower layer. Like the Earth, Mars's coating is much thicker than the outer shell, deep to 1,560km. The above coating is the basis for forming tectonic places on Earth. However, the upper coating of Mars can double or even more than the upper coating of the Earth.Amir Khan, Geophysia at the Swiss Federal Technology Institute Zurich and is co-author of The article, said it is "can be a simple explanation why we don't see tectonic segments on Mars". This hardness can prevent the above layers of Mars separated into tectonic places, causing its surface not diverse such as mountains, oceans, basins, plains and canyons of the earth. Creating the array of a planet is basically derived from the thermal conductivity from within the planet to the outer shell. The shock waves to Insight show that the coating of Mars is relatively cold, causing the surface s . Dịch vụ:
