This view of the American flag medallion on NASA's Mars rover Curiosity was taken by the rover's Mars Hand Lens Imager (MAHLI) during the 44th Martian day, or sol, of Curiosity's work on Mars (Sept. 19, 2012).
The HiRISE camera aboard NASA's Mars Reconnaissance Orbiter acquired this closeup image of a light-toned deposit in Aureum Chaos
On June 25, NASA announced that the first Landing Site/Exploration Zone Workshop for Human Missions to the Surface of Mars will take place Oct. 27-30, at the Lunar and Planetary Institute in Houston.
These days you can't seem to go anywhere in the Internet without seeing #JourneyToMars slapped on Tweets about, well, everything that NASA does - regardless of how it is actually related to sending humans to Mars.
India's Mars Orbiter Spacecraft is in its 100th orbit around Mars today (Start : June 22, 2015 End: June 25, 2015).
The high seas of Mars may never have existed, according to a new study that looks at two opposite climate scenarios of early Mars and suggests that a cold and icy planet billions of years ago better explains water drainage and erosion features seen on the planet today.
When NASA launches its next mission on the journey to Mars a stationary lander in 2016 the flight will include two CubeSats.
This image shows the region around Comas Sola crater taken by Mars color camera (MCC) on board India's Mars Orbiter Spacecraft.
This image shows part of the Hesperia Planum region, taken by Mars color camera (MCC) on board India's Mars Orbiter Spacecraft.
The High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter acquired this closeup image on March 30, 2015.
Here on Earth, we are used to the wind shaping our environment over time, forming smooth, sculpted rocks and rippling dunes. In this way, Mars is more similar to Earth than you might expect.
Testing is underway on NASA's next mission on the journey to Mars, a stationary lander scheduled to launch in March 2016.
At first glance, the region covered by this latest Mars Express image release appears to be pockmarked with impact craters. But the largest structure among them may hold a rather explosive secret: it could be remains of an ancient supervolcano.
This image of a circular depression on the surface of Mars was acquired on Jan. 5, 2015 by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter (MRO).
Several satellites orbit Mars and on satellite images, researchers have been able to observe the shape of glaciers just below the surface.
I just listened to 45 minutes of NASA presentations at the NASA Advisory Committee's Human Exploration and Operations Committee Meeting. The topic: radiation risks during a human mission to Mars. I have seen this movie before.
Two-tone mineral veins at a site NASA's Curiosity rover has reached by climbing a layered Martian mountain offer clues about multiple episodes of fluid movement. These episodes occurred later than the wet environmental conditions that formed lake-bed deposits the rover examined at the mountain's base.
NASA's Curiosity rover is using a new experiment to better understand the history of the Martian atmosphere by analyzing xenon.
A series of observations from Mars orbit show how dark blast zones that were created during the August 2012 landing of NASA's Curiosity rover have faded inconsistently.
Researchers from Brown University have completed a new analysis of an ancient Martian lake system in Jezero Crater, near the planet's equator.
