According to the National Space Administration's Lunar Exploration and Space Engineering Center, as of now, the Tianwen-1 mission has obtained more than 1480GB of original scientific detection data, and the Chinese scientist team has achieved a number of original scientific results based on the first-hand scientific data obtained. Several studies have shown that there are water activity remains in the landing area of the Zhurong Mars rover.
" Zhurong " landing area Utopian plain South
Water activity
The landing area of Zhurong rovers is located in the south of the Martian utopian plain. After more than a year of patrol exploration, Zhurong rovers have obtained a large amount of scientific exploration information. The image data of the navigation and terrain cameras show that there are plate-like rocks rich in water minerals in the landing area, which are closely related to water activity.
Hyper , a researcher at the National Space Science Center of Chinese Academy of Sciences, Liu Yang, said: "The rock is brighter in color. Through spectral data, it shows that its components are salts rich in some water-containing minerals, such as sulfate , which we call cementing. It plays a cementing role between soil particles, and after a compaction, it forms plate-like rocks."Hyper 4
These rocks are closely related to water activities. Scientists speculate that water activities occur roughly in the late Amazonian period of Mars . "In the past 1 billion years, Mars may have some suitable origins of life or the existence of such climatic conditions, and it is also likely to be in a relatively mild space underground," said Liu Yang.
As of now, the Tianwen-1 orbiter has been in orbit for more than 780 days, and the Mars rover has traveled a total of 1,921 meters, completing the established scientific exploration mission. In the future, the scientific research team will also obtain more scientific results through research on first-hand scientific data independently obtained by our country.
forms the basic map of the landing area
provides support for subsequent exploration
Zhurong rover landing in the southern part of the Martian utopian plain. Another achievement achieved in my country's Mars exploration mission is the formation of a basic map of the landing area, which will provide good data support for the fine detection of subsequent landing areas and scientific exploration planning.
landing area basic map data consists of two parts, the first part is mainly made of images obtained by a high-resolution camera carried by the surrounder. Liu Jianjun, chief designer of the ground application system of Tianwen-1 mission, introduced: "It has a spatial resolution of about 0.7 meters, and its terrain can reach a spatial resolution of meter. There is no data in our landing area abroad, so it actually reflects the results of our independent innovation." The second part of the data of
comes from Zhurong Mars rover, which further enriches the basic map data by conducting detailed detection and imaging of the surface of the landing area. Provide more refined and effective information for subsequent fine detection and scientific planning. "Through these 13 load combinations, including the morphology, shallow structure, magnetic field, and its meteorological characteristics, a complete set of global comprehensive detection and local detailed detection, coupled with the key detection in the landing area, is very valuable for subsequent scientific research," said Liu Jianjun.
High-quality data analysis
helps to obtain a number of scientific research results
As of now, the Tianwen-1 mission has obtained 1480GB of original scientific detection data. However, all scientific research results that have been achieved do not come directly from these original data, but from the data products they form. The original data returned in the
Tianwen No. 1 task contains a lot of content. Therefore, after receiving this data, ground researchers must first decode it, extract different types of information from the complex original data to form standard data products, and then provide it to the scientist team for research.
Tianwen-1 mission chief scientist Pan Yongxin said that in order to understand Mars, he could only rely on foreign data, and these are not first-hand data, so it is difficult to make more new and major discoveries. "Tianwen-1 provides Chinese scientists with first-hand data, which means that we can analyze our scientific stories from the original data at the most fundamental level. The autonomy of data indicates that we will have high initiative in scientific discovery."
through the Tianwen-1 mission not only achieved long-distance data transmission of hundreds of millions of kilometers, but also mastered the methods of how to effectively extract scientific data, laying a solid foundation for subsequent interplanetary exploration in my country. After the Zhurong Mars rover is automatically awakened,
will continue to march southward. It is expected that Mars' environmental conditions will automatically wake up and continue to march southward.
"Because we happen to be in a north-south interactive zone of Mars, some people speculate that it is the boundary of an ancient ocean, so we go south towards the edge, and geological phenomena will be richer. "Pan Yongxin said, "The Zhurong patrol vehicle will carry the loads of various scientific instruments when it arrives, just like the eyes of our scientists, which is equivalent to an unmanned robot coming there to detect. The current basic data we have obtained are very important for our exploration tasks in the future, whether it is the engineering perspective, technical perspective, or scientific detection results perspective. ”
In addition, the scientific research team also used Tianwen-1 exploration data to obtain a number of excellent scientific achievements in the shallow underground structure of Mars, the distribution of magnetic fields, ions and neutral particles in the Martian space environment, and the gravity field of Mars.
