Why is Mars dry? Water might escape the atmosphere more effectively than previously thought, potentially helping to explain how the Red Planet lost its vast oceans.
The European Space Agency and Russia's Federal Space Agency have teamed up on the ExoMars orbiter and rover mission to the Red Planet. See the latest news, images, videos and more on the ExoMars Trace Gas Orbiter and Rover mission here.
The European-Russian ExoMars 2020 mission will have to find some parachute fixes fast if it wants to be ready for launch next summer.
Feel like going for a spin around Mars? A new video shows a 3D view of where the European-Russian ExoMars rover will land, in a region that was likely filled with water billions of years ago.
Rippling, dark-flecked sand dunes near Mars' north pole look like melting chocolate-chip ice cream in an image captured by the European-Russian Trace Gas Orbiter.
Europe hopes a robot called Rosalind Franklin will become its first rover on Mars, but the spacecraft has some big tests to pass before it launches next year.
The complex, ambitious plan involves two rovers, a lander, an orbiter and an unprecedented launch off the Martian surface.
Drilling for signs of life on Mars, as two rover missions plan to do soon, is a pretty sound strategy, a new study suggests.
The UK Space Agency has launched a public competition to name the U.K.-built ExoMars rover, which is scheduled to launch toward the Red Planet on a life-hunting mission in 2020.
Europe's upcoming Mars rover features a powerful toaster oven-size lab that will search for signs of life on the Red Planet.
The largest-ever parachute bound for Mars, which will land Europe's ExoMars rover on the surface of the Red Planet in 2021, passed the first in a series of tests in Sweden.
A spacecraft that will sniff for possible signs of life in the Martian atmosphere is nearly ready to start its science work at the Red Planet.
