Will Mars soon be hidden under a veil of dust? Let's hope not. We explore the current storm and the planet's upcoming close opposition.
NASA’s Curiosity rover has detected both methane in Mars’s atmosphere and carbon-bearing organic compounds in its rocks. But it’s unclear where these molecules come from — or whether there’s any biological connection.
An innovative technique has allowed NASA's Curiosity Rover to resume drilling Martian rocks. But the partially successful test shows that more work remains to be done.
Barely visible water-ice clouds coast across Mars’s skies in new videos from the Curiosity rover.
Samples taken from two drill holes on Mars support the idea that Mars lost a whole lot of water fairly early in its history.
Here's what we know so far about the fate European Space Agency's Schiaparelli mission.
Welcome to Mars: the European Space Agency's ExoMars Trace Gas Orbiter sets up shop around the Red Planet.
Let Mars be your guide to no fewer than 15 diverse and delightful double stars that pepper its path through Scorpius and Libra this opposition season.
Mars was once far wetter than it is now — but just how much rain fell, and when?
Spacecraft images are keeping an eye on little surface flows on Mars that show up in midsummer, then fade over time. It's the strongest suggestion yet that the Red Planet can get wet.
The new year opens with the magnificent pairing of the solar system's largest planet with one of its smallest.
By tracking deviations in spacecraft orbits, planetary scientists have created a high-resolution map of the Red Planet's gravitational pull.
NASA’s Mars orbiter MAVEN has painted a detailed picture of how the solar wind robs the Red Planet of its atmosphere.
NASA’s MAVEN mission has confirmed that the solar wind stripped the Red Planet of its atmosphere.
Doing anything on New Year's Eve? Before you start toasting, don't miss an exceptionally close conjunction of Mars and Neptune.
At last, a fine Mars apparition: on May 22nd the Red Planet reaches opposition, shining almost as bright as Jupiter, and the planet makes its closest approach to Earth on May 30th.
Mission planners have devised an unusual strategy for protecting orbiting spacecraft when Comet Siding Spring passes the Red Planet in October 2014.
NASA’s MAVEN mission has discovered a new population of particles in Mars’s upper atmosphere. It’s also found a plume of particles escaping from the planet’s poles, confirming atmospheric loss is happening today.
NASA’s MAVEN spacecraft has detected dust high in Mars’s atmosphere and auroras across the planet’s northern hemisphere.
The Curiosity rover has detected organic molecules in ancient rocks on Mars.
Curiosity spotted polygonal shapes on the surface of rocks on Mars — now, analysis of these mud cracks is revealing the history of the long-ago lake that once filled Gale Crater.
Six years from now, there will be a new NASA robot heading to the Red Planet: the Mars 2020 rover. On July 31st mission planners unveiled the rover’s seven scientific instruments, which will pave the way for human exploration of Mars.
Scientists and engineers gathered together to figure out what would make a good Martian landing site and what hurdles they’ll have to overcome for a 2035 launch.
It's showtime for the King of the Rings! Time to get your telescope out to see and share Saturn, which comes to opposition this week.
The innovative joint European Space Agency/Roscosmos Schiaparelli lander begins its three day solo journey to the Martian surface this weekend.
