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.
One scientist says that soil deep within a crater dating to some 3.7 billion years ago and imaged by the rover Curiosity contains evidence that Mars was once much warmer and wetter.
NASA Mars Curiosity rover continues its trek across the Red Planet, continually making new discoveries. Now, the rover has spotted a massive iron meteorite called "Lebanon" and has snapped a photo of the rock to send back to Earth.
Scientists have created the most detailed map of Mars to date. The U.S. Geological Survey has released a new global geological map of the Red Planet that reveals the startling features of the planet's surface.
NASA's Mars Reconnaissance Orbiter (MRO) has made some new discoveries when it comes to the gullies on Mars' surface.
Could there actually be water on the surface of Mars? It's possible, according to a new study.
Flying saucers aren't just for movies about aliens. NASA recently successfully tested its Low-Density Supersonic Decelerator (LDSD), a test vehicle meant to evaluate new landing technologies for future Mars missions in the shape of a saucer.
Scientists may have discovered something new about the Red Planet's atmosphere. Satellite-acquired data reveals that dust particles in Mars' atmosphere actually consist of two types, revealing a bit more about the planet.
