The findings potentially solve the paradox of how liquid water seems to have persisted on Mars even when the climate grew too ...

A Martian mystery that sparked years of debate — an alleged lake buried beneath miles of ice — now looks far less watery than scientists hoped. A new radar study from NASA’s Mars Reconnaissance ...

'Because the ice is thin and temporary, it would leave little evidence behind, which could explain why rovers have not found ...

A new study suggests a habitable past and signs of ancient microbial processes on Mars. Led by NASA and featuring key analysis from Imperial College London, the work has uncovered a range of minerals ...

The European Space Agency’s Mars Express orbiter captured this view of Mars’ south polar ice cap Feb. 25, 2015. Three years later, the spacecraft detected a signal from the area to the right of the ...

New climate modeling suggests that small lakes on ancient Mars could have stayed liquid for decades, even in a generally cold environment. Small lakes on early Mars may have stayed in liquid form for ...

Small lakes on ancient Mars may have remained liquid for decades, even with average air temperatures well below freezing. Using a climate model adapted for Martian conditions, a team of researchers ...
