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.
Could there be life on Mars? Scientists are learning a bit more about the planet after analyzing soil samples from the Red Planet after NASA's rover Curiosity landed in the Gale crater.
Whether or not Mars ever possessed or possesses life is still under debate. Now, a new meteorite from the Red Planet may provide some answers. It seems to indicate that Martian life is far more probable than previously thought.
Scientists believe that warming and water flow on Mars was episodic and likely related to ancient volcanic eruptions.
Could there be organic matter on Mars? The organic matter that was recently detected by NASA's rover Curiosity probably isn't due to contamination brought from Earth, as originally thought.
Scientists have discovered that macroweather exists on Mars, which reveals further insights into the Martian climate.
When Comet Siding Spring brushed past Mars, scientists captured data using NASA's MAVEN mission. Now, researchers have found that the comet was actually the cause of an intense meteor shower and added a new layer of ions, or charged particles to the ionosphere.
NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has given scientists their very first look at the atmosphere of Mars.
