Chinese exploration on Mars achieves valuable scientific results

China’s first Mars exploration mission has achieved valuable scientific results, the China National Space Administration (CNSA) said Tuesday.

As of Thursday, the Tianwen-1 orbiter had operated normally for more than 780 days and the Zhurong rover had traveled 1,921 meters from the surface of Mars, the CNSA added.

China’s Tianwen-1 probe orbiter and explorer have completed planned scientific exploration missions and acquired 1,480 gigabytes of raw scientific data.

Chinese researchers conducted a comprehensive study of typical landforms in the landing zone, including concave cones, impact craters and rills, and revealed a significant link between ridge formation and water activity.

Through camera images and spectral data, the researchers found phreatic minerals in sheet-like hard crustal rocks near the landing zone, which showed that there were many activities with liquid water in the landing zone since a billion years ago. .

These new results reveal the effect of wind and water activities on geological evolution and environmental changes on Mars.

This strongly supports the hypothesis that there was once an ocean on Mars’ Utopia Planitia.

It also enriches human scientific understanding of geological evolution and environmental changes on Mars.

In addition, the researchers also used the Tianwen-1 exploration data to obtain several outstanding scientific achievements, including the relationship between the density of rocks on the surface of Mars and degrees of surface erosion, the distribution of ions and neutral particles in the space environment near Mars and the Mars gravity field.
