It may seem impossible that water could flow on the frigid surface of Mars, but a new study in a simulated Red Planet environment shows that a type of salt there may melt the ice it touches. This ...

The red planet might still have liquid water, suggests information collected by Nasa's Curiosity rover. Researchers have long known that there is water in the form of ice on Mars. Now, new information ...

The pervading carpet of perchlorate chemicals found on Mars may boost the chances that microbial life exists on the Red Planet — but perchlorates are also perilous to the health of future crews ...

Perched on a vast plain above the arctic circle of the Red Planet, NASA’s Phoenix Mars Lander has found new evidence that liquid water was once present in the north polar region and interacted with ...

Researchers have long known that there is water in the form of ice on Mars. Now, new research from NASA's Mars rover Curiosity shows that it is possible that there is liquid water close to the surface ...

The clue comes from the presence in the soil of calcium perchlorate, they said. This is a type of salt that is highly absorbent and lowers the freezing point of water so that it remains liquid. The ...

Water could have flowed on the surface of Mars with the help of salts in the Martian soil that can melt ice, just as salts on Earth can be used to melt ice on slippery winter roads and sidewalks, ...
