Scientists may have found more evidence for water on Mars.
Scientists have learned a bit more about an ancient lake system on Mars.
Settling on Mars isn't going to be easy, though plans are moving forward. Now, scientists have created an innovative new technique that may allow Martian colonists to harvest energy from carbon dioxide.
It turns out that Mars may have held more water than Earth's Arctic Ocean and covered a great portion of the planet's surface than the Atlantic. Scientists have found that the Red Planet was once watery, and that it lost its ocean over time.
NASA's Curiosity rover has detected an episodic increase in the concentration of methane in Mars' atmosphere.
Scientists have encountered a mystery above the surface of Mars. They've spotted strange plumes reaching high above the Red Planet's surface that they're unable to explain.
A meteorite that was discovered in the Moroccan desert may just represent large swathes of the Martian crust.
A new analysis of Martian chemical maps has revealed that there may be water bound to sulfates in the soil on Mars. Scientists have discovered a spatial association between the presence of sulfur and hydrogen found in the soil.
Most people are aware that Mars once harbored water. These days, water vapor can actually be found in the Martian atmosphere.
These days, Mars doesn't have much in the way of an atmosphere. And yet it did in its ancient past. Now, NASA's newest Mars orbiter, MAVEN, has discovered key features about the loss of the planet's atmosphere to space over time.
Scientists are learning a bit more about the role of water on Mars, thanks to observations by Curiosity. They've found that the Red Planet's Mount Sharp was built by sediments deposited in a large lake bed over tens of millions of years.
