As of now, the Tianwen-1 orbiter has been in orbit for over 780 days, according to information from the China National Space Administration (CNSA). The rover traveled a total of 921 meters on Mars and obtained 480 GB of original scientific exploration data.
Extensive studies of typical landforms, such as concave cones, barrier impact craters, and ditches scattered at the landing site, have revealed an important link between the formation of these landforms and water activities.
Thanks to camera images and spectral data, hydrated minerals were found in plate-shaped hard-shell rocks near the landing site. A large amount of liquid water activity has been proven at the landing site for over 1 billion years.
On the other hand, camera images and traces of the rover's movement indicated that the soil at the landing site had strong compressive strength and low creep parameters related to water activity and experiencing sand erosion.
Recent studies have revealed the impact of sandstorms and water activities on geplogical evolution and environmental changes on Mars, providing strong support for the assumption that there is an ocean on the Martian Utopia Plain. Related studies have been published in domestic and international academic journals such as "Nature Astronomy", "Nature Geoscience", "Science Advances" and "Chinese Science".
