NASA’s Perseverance rover found pale rocks containing kaolinite on Mars, a mineral that forms in warm, wet conditions.

Research published late last year indicated “seismic discontinuities in the Martian crust” that scientists believe could be an indicator of liquid water under the Martian surface, raising the ...

In 1975, NASA’s Viking mission tested Martian soil for microbial life using liquid water. A recent theory suggests this approach may have destroyed microbes adapted to Mars' dry, salt-driven ...
