Artist’s conception of MAVEN’s Imaging UltraViolet Spectrograph (IUVS) observing the “Christmas Lights Aurora" on Mars. MAVEN observations show that aurora on Mars is similar to Earth’s "Northern L...

The Martian surface bears ample evidence of flowing water in its youth, from crater lakes and riverbeds to minerals that only form in water. But today Mars is cold and dry, and scientists think tha...

Mars is experiencing large regional dust storms over its northern hemisphere during the past week.

Inside the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, engineers and technicians test deploy the twin solar arrays on the Mars Atmosphere and Volatile Evolution,...

These images from the Imaging Ultraviolet Spectrograph on NASA's MAVEN orbiter show the appearance of a bright aurora on Mars during a solar storm in September 2017. The purple-white colors shows t...

Seasons change even on Mars and NASA's fleet of explorers are helping scientists learn more about the effects on the Red Planet.

Energetic particles from a large solar storm in September 2017 were seen both in Mars orbit by NASA's MAVEN orbiter, and on the surface of Mars by NASA's Curiosity Mars rover.

This is an artist's model of an early Mars - billions of years ago - which may have had oceans and a thicker atmosphere.

Mars was once on track to become a thriving Earth-like planet, yet today it is an apparently lifeless wasteland. A NASA spacecraft named MAVEN will soon journey to Mars to find out what went wrong ...

NASA's Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft went through weeks of processing to ensure it was ready for a 10-month trip to the Red Planet. Watch as time-lapse video condense...
