Could life be found in frozen sea spray from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, that this life should be detectable by instruments launching in the fall ..read more

The period that liquid water was present on the surface of Mars may have been shorter than previously thought. Channel landforms called gullies, previously thought to be formed exclusively by liquid water, can also be formed by the action of evaporating CO2 ice, according to a new study ..read more

Sand ripples are symmetrical. Yet wind -- which causes them -- is very much not. Furthermore, sand ripples can be found on Mars and on Earth. They would be even more fascinating if the same effect found on Mars could be found here on Earth as well. What if one unified theory could explain their formation on both planets ..read more

Scientists suspect Mars once had long-lived rivers, lakes and streams. Today, water on Mars is found in ice at the poles and trapped below the Martian surface. Researchers now reveal that Mars also may have had hydrothermal systems based on the hydrated magnesium sulfate the rover identified in the volcanic rocks ..read more

Mars was once a wet world. The geological record of the Red Planet shows evidence for water flowing on the surface -- from river deltas to valleys carved by massive flash floods. But a new study shows that no matter how much rainfall fell on the surface of ancient Mars, very little of it seeped into an aquifer in the planet's southern highlands ..read more
