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.
On July 5th, the Moon has a remarkably close brush with Mars, followed two nights later by a similar rendezvous with Saturn.
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.
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 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.
Samples taken from two drill holes on Mars support the idea that Mars lost a whole lot of water fairly early in its history.
NASA’s MAVEN spacecraft has detected dust high in Mars’s atmosphere and auroras across the planet’s northern hemisphere.
Scientists have detected glass in Martian craters, created by the fierce heat of impacts that melted the Red Planet’s surface.
Scientists have confirmed that water-soaked salts likely create dark seasonal lines on Mars.
NASA’s Mars orbiter MAVEN has painted a detailed picture of how the solar wind robs the Red Planet of its atmosphere.
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.
By tracking deviations in spacecraft orbits, planetary scientists have created a high-resolution map of the Red Planet's gravitational pull.
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.
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.
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.
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.
Doing anything on New Year's Eve? Before you start toasting, don't miss an exceptionally close conjunction of Mars and Neptune.
NASA’s MAVEN mission has confirmed that the solar wind stripped the Red Planet of its atmosphere.
