China’s Zhurong rover on Mars has detected current aqueous actions inside its exploration zone at Utopia Planitia.
A brand new analysis paper in Science Advances notes that Mars’ local weather is chilly and dry in the newest epoch, and liquid water actions are thought of extraordinarily restricted. Earlier orbital information solely present sporadic hydrous minerals within the northern lowlands of Mars excavated by giant impacts.

However utilizing the short-wave infrared spectral information obtained by the Zhurong rover of China’s Tianwen-1 mission, scientists have recognized hydrated sulfate/silica supplies on the Amazonian terrain on the touchdown web site.
These hydrated minerals are related to bright-toned rocks, and are interpreted to be duricrust developed regionally.

Groundwater rising or subsurface ice melting
The lithified duricrusts means that formation with substantial liquid water originates by both groundwater rising or subsurface ice melting. The rover has gathered on-the-spot proof for aqueous actions suggesting a extra lively Amazonian hydrosphere for Mars than beforehand thought.

“The Zhurong touchdown web site (and the northern lowlands) could include a substantial quantity of accessible water within the type of hydrated minerals and probably floor ice for in situ useful resource utilization for future human Mars exploration,” the analysis paper concludes.
The Tianwen-1 lander, carrying the rover, carried out a profitable soft-landing on Mars in mid-Might 2021.
