Liquid water formed Martian landscape a billion years ago


Great past liquid water activity has been recorded at the Zhurong landing zone, China’s first Mars rover, which has been dated to about a billion years ago.

The discovery of liquid water activity means that there may have been some conditions suitable for the origin or existence of life on Mars in the last billion years, the mission managers explained.

Through the exhaustive study of typical relief formssuch as concave cones, wall impact craters and trenches distributed in the landing zone, the scientific research team has revealed the important connection between landform formation and water activity in the Zhurong landing zone.

Camera images and spectroscopic data show that there are water-bearing minerals in slab-crustal rocks near the landing area, providing evidence that there was a lot of liquid water activity in the Zhurong landing area a billion years ago.

“As liquid water activity has been found, we believe that there may be some climatic conditions suitable for the origin of life or the existence of such conditions in the last billion years on Mars,” Liu Yang told state television CCTV. researcher at the National Space Science Center of the Chinese Academy of Sciences (CAS), quoted by The Global Times.

These new results reveal the influence of Martian sand and water activity on geological evolution and environmental changes, provide strong support for the conjecture that oceans once existed on the Martian Utopia Planum and enrich human scientific knowledge about geological evolution and environmental changes on Mars, the CNSA said.

The scientific research team also used the data from the Tianwen-1 probe to obtain a series of outstanding scientific results on the relationship between the density of rocks on the Martian surface and the degree of surface erosion, ion distribution and neutral particles in near space. Space environment of Mars, as well as the Martian gravity field.

The Tianwen-1 orbiter continues to conduct scientific exploration in the remote sensing mission’s orbit and continues to accumulate scientific data, the CNSA said.

The Zhurong rover is currently in hibernation and is expected to wake up later this year when environmental conditions on Mars improve.. Once its normal operating condition is confirmed, Zhurong will continue traveling south to get more data from the roaming probe.

The results of this research have been published in academic journals such as Nature Astronomy, Nature Geoscience, Science Advances and Science China.
