Late this month, ESA’s Mars Express will make the closest flyby yet of the Red Planet’s largest moon Phobos, skimming past at only 45 km above its surface.
The larger of the two moons of Mars, Phobos, passes directly in front of the other, Deimos, in a new series of sky-watching images from NASA's Mars rover Curiosity.
Rolling robots like spiky tumbleweeds could be used to explore the moons of Mars, says a team of NASA, Stanford and MIT engineers.
The European Space Agency says that one of its ground stations has managed to re-establish contact with Russia's Phobos-Grunt probe, two weeks after control was lost.
A Russian Mars probe, its first interplanetary mission in 15 years, failed to take the correct course after launch, the Russian space agency has reported.
Mars' largest moon, Phobos, may have been blasted off into space by some catastrophe on the planet's surface, say two different scientific studies.
Mission controllers for the Mars Express have created a video showing the view as the spaceship orbits Mars.
