Provide more data support for subsequent detection!Experts analyze the scientific research results of the first Mars detection task →

According to the National Space Administration's Moon Exploration and Aerospace Engineering Center, as of now, Tianwen No. 1 missions have obtained the original scientific detection data of more than 1480GB, and the scientific data of my country's scientist team has achieved a number of original scientific results.

The "Zhu Rong" landing area once existed in water activities

A number of research results show that there are marks of water activity in the landing area of ​​Zhurong Mars.

The landing area of ​​Zhurong Mars is located in the south of the Mars Utopia Plain. After more than a year of inspection and detection, Zhu Rong Mars has obtained a large number of scientific detection information. Among them, the image data of navigation and terrain cameras show that there are plate -like rocks rich in minerals in the landing area, and these rocks are closely related to water activity.

Liu Yang, a researcher at the National Space Science Center of the Chinese Academy of Sciences: (Rock) It has a brighter color. Through spectrum data, we see that its ingredients are some salt -containing minerals, such as sulfate, we are called tunnels. It plays a collapse between soil particles. After a compact effect, it forms plate -like rocks.

Through further research on rocks, the scientific research team speculated that the approximate time range of water activities was the late stage of Mars Amazon.

Liu Yang, a researcher at the National Space Science Center of the Chinese Academy of Sciences: Since there is water, we believe that there may be some suitable life origin or such climate conditions in Mars in nearly 1 billion years. These climate conditions are likely to be in a more gentle space underground.

As of now, the Tianwen No. 1 surrounding device has been running for more than 780 days, and the Mars car has been driving for 1921 meters to complete the established scientific detection task. In the future, the scientific research team will also obtain more scientific results through the research of first -hand scientific data obtained by my country.

Form the basic map of the landing area to provide support for subsequent detection

Another achievement obtained in the Mars detection mission in my country is to form a basic map of the landing area. The map covers information such as terrain and geological structures in the landing area, which will provide good data support for the subsequent landing areas and scientific detection and planning.

The data of the basic map of the landing area consists of two parts, and the first part is mainly made from the image obtained by the high -resolution camera carried by the surrounding device.

Liu Jianjun, chief designer of Tianwen No. 1 task ground application system: It is about 0.7 meters of spatial resolution, and its terrain can reach rice -level spatial resolution. There is no (data) in our landing area abroad, so it actually reflects the result of our independent innovation.

The second part of the data comes from Zhu Rong Martian car. Through detailed detection and imaging of the surface of the landing area, it further enriches the basic map data. Provide more fine and effective information for subsequent fine detection and scientific planning.

Liu Jianjun, chief designer of Tianwen No. 1 task ground application system: Through these 13 -loading combinations, including its appearance, shallow structure, magnetic field, and its weather characteristics, form a complete set of global comprehensive detection and Local detailed detection, coupled with key detection in the landing area, is very valuable for our subsequent scientific research.

High -quality data analysis helps to obtain a number of scientific research results

As of now, Tianwen No. 1 task has obtained 1480GB of original scientific detection data. But all the scientific results that have been obtained are not directly from these original data, but are derived from the data products formed.

The original data returned by Tianwen No. 1 mission contains a lot of content. Therefore, after receiving these data, ground scientific researchers must first decode, extract different types of information from complex original data, form standard data products, and then provide a team of scientists for research.

Pan Yongxin, chief scientist of Tianwen No. 1 task science application: which are time information, which are location information, which are engineering signal information, and which are not detected information. The ground application system must do a lot of work. To draw cocoon and make them into our products. It is not so simple to use these data, so this is the first challenge in itself.

Prior to this, we wanted to know Mars, and we could only rely on foreign data, and these are not one -handed data, so it is difficult to have more new and major discoveries.

Pan Yongxin, chief scientist of Tianwen No. 1 task science: Tianwen No. 1 provides first -hand data to Chinese scientists, which means that we can analyze our scientific stories mostly from the original data. The autonomy of data indicates that our initiative will be high in scientific discovery.

Through Tianwen No. 1 mission, we not only achieved long -range data transmission of hundreds of millions of kilometers, but also mastered how to effectively extract scientific data, laying a solid foundation for subsequent planetary detection in my country.

Zhu Rong will continue to travel south after the Mars car wakes up autonomously

Zhu Rong Mars is currently dormant and is expected to wake up autonomously after the environmental conditions of Mars at the end of the year. After confirming that the working status is normal, Zhu Rong will continue to travel south to obtain more inspection and detection data.

Pan Yongxin, chief scientist of Tianwen No. 1 task science application: Continue to the south because we happen to interact with the north and south of Mars. Some people speculate that it is a border of an ancient ocean. Go, geological phenomena will be more abundant, this principle will not change.

According to the scientific detection results we have obtained, we will plan the detection goals and paths of Zhu Rong Mars in the future. We hope to obtain more effective information and provide rich scientific data for further understanding of the landing area.Pan Yongxin, chief scientist of Tianwen No. 1 task science application: We will carry the load of various scientific instruments, just like the eyes of our scientists, which are equivalent to we are an unmanned robot to detect.At present, these we have obtained, regardless of the engineering perspective and technical perspective, from the perspective of scientific detection results, it is a very important basic data for future detection tasks.

In addition, the scientific research team also uses Tianwen No. 1 detection data to obtain a group of outstanding scientific achievements in the shallow structure of Mars, the distribution of magnetic fields, ions and neutral particles in the Mars space environment, and Mars gravity field.Essence
