A new study suggests that heavy rainfall might have changed the surface of Mars. The rainfall eroded the surface creating rivers.
Metal ions are only observed in an atmosphere on Mars and of the Earth. Scientists say, however, that the two behaves differently.
A magnetic field to protect Mars could make it more viable to host life or at least the crew for future missions. This is the concept that NASA presented during the Planetary Science Vision 2050 workshop.
The European Space Agency’s (ESA) ExoMars Trace Gas Orbiter is making its first scientific observations on Mars. Science teams are calibrating their instruments and are about to make the first test observations.
NASA's MAVEN probe identified fluctuating amount of water escape from the Martian atmosphere.
A new study suggests that the discovery of manganese oxide on Mars could prove that there was Earth-like oxygen on the Martian atmosphere during the ancient times.
Ever wonder what Mars smells like? Researchers have long known that the average aroma of a planet can tell you a lot about its atmosphere. Now, experts are commanding the Mars curiosity rover to take a long sniff of the Red Planet's 'body odor' to learn more about its history.
It seems that despite the fact that humanity has had orbiters in the sky and landers on the Martian surface since the 1970s, the Red Planet is still full of surprises. A new Mars orbiter sent by NASA has now noticed not one, but two unexpected phenomena in the planet's atmosphere: an unexplained high-altitude dust cloud and an unusual aurora.
