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.
Finding water on Mars is an important part of the hunt for life on the Red Planet. Yet actually detecting it isn't easy. Now, researchers have developed a new method for finding water on Mars.
There may be evidence for past life on Mars. A Martian meteorite fragment that's about 1.3 billion years old may show that it was once possible that life existed on the Red Planet.
NASA's Mars Curiosity rover continues its exploration of the Red Planet. Now, it's officially reached a major landmark: Mount Sharp.
NASA's Mars Curiosity rover is continuing its trek across the Red Planet and now, scientists have chosen a new rock for a drilling target. The new choice should hopefully tell researchers a bit more about the geological history of the planet.
The next NASA rover is slated to explore Mars as never before. Planned to be sent to the Red Planet in 2020, the new rover will carry seven carefully-selected instruments that will conduct unprecedented science and exploration technology investigations.
NASA's Mars rover Opportunity has reached a new mile marker. It's officially driven more than 25 miles after landing on the Red Planet in 2004, which means that it now holds the off-Earth roving distance record.
