ESA's Mars Express has shed new light on the Red Planet's rare ultraviolet aurora by combining for the first time remote observations with in situ measurements of electrons hitting the atmosphere.
Scientists may be closer to solving the mystery of how Mars changed from a world with surface water billions of years ago to the arid Red Planet of today.
In the 1870's astronomers first noted the presence of yellow clouds on the surface of Mars and suggested they were caused by windblown dust. Today, dust storms on Mars are well known and those that display visible structures ...
A hot topic in science over the past few decades has been whether liquid water is present or has been present on Mars in the past few millions of years. But despite a lot of research no conclusive answer has been put forward ...
Next week, a visual and infrared camera designed at Arizona State University will pass 60,000 orbits of the Red Planet.
India's first ever robotic explorer to the Red Planet, the Mars Orbiter Mission, more affectionately known as MOM, has captured an absolutely dazzling array of images of the fourth rock from the Sun.
NASA has beefed up a process of traffic monitoring, communication and maneuver planning to ensure that Mars orbiters do not approach each other too closely.
Throughout his career Ronald Greeley was passionate about exploring Mars, so it's fitting that the late Arizona State University professor's name will grace maps of the Red Planet.
Could water have carved channels on Mars as recently as 500,000 years ago? If that's the case, it would boost the case for relatively recent life on the red planet.
