[Growth Knowledge] The first Mars detection task in my country has gained rich scientific results

National Space Administration News on September 18th, as of September 15, 2022, Tianwen No. 1 surrounder has been running for more than 780 days, and the Martian car has been driving for 1921 meters to complete the established scientific detection task, obtaining the original scientific detection data of 1480GB Essence The scientific research team has achieved rich scientific results through the research of first -hand scientific data obtained by my country. According to 1480GB. The scientific research team has achieved rich scientific results through the research of first -hand scientific data obtained by my country.

Through comprehensive research on typical landforms such as concave cones, barriers, and grooves distributed in the landing area, it reveals an important connection between the formation of the above -mentioned landforms and water activities.

Through camera images and spectral data, water -containing minerals were found in plate -shaped hard shell rocks near the landing area, which proved that there was a large amount of liquid water activity in the landing area since this period of 1 billion years (evening Amazon).

Combined with information such as camera images and Mars vehicle mobile ruts, it is found that the soil in the landing area has strong pressure strength and low friction parameters. It has the characteristics that are related to water activities and experience wind and sand abrasion.

These new achievements reveal the impact of Mars wind and sand and water activities on geological evolution and environmental changes, and provide strong support for the presence of ocean in the Mars Utopia Plain, which enriches human scientific awareness of Mars geological evolution and environmental changes. The results have been published in authoritative academic journals at home and abroad.

In addition, the scientific research team also uses Tianwen No. 1 detection data to obtain a number of in terms of the relationship between the rock density and the degree of erosion on the surface, the distribution of neutral particles in the near -fire space environment, and the Mars gravity field. Excellent scientific achievements.

At present, Tianwen No. 1 surrounding device continues to carry out scientific detection in the remote sensing mission track, and continues to accumulate scientific data.
