This eerie portrait of Mars' moon Phobos in ultraviolet light was snapped by the NASA orbiter MAVEN as their orbits crossed paths.
On Thursday (Jan. 14), the European Space Agency's Mars Express orbiter is set to pay Phobos a visit in what will be the mission's closest flyby of the Martian moon this year.
A new study shows the moon is likely to break apart before it hits the atmosphere, creating a debris ring that will encircle Mars for millions of years.
Scientists have known for some time that Phobos, the larger of Mars’ two small moons, is a victim of gravity, edging closer toward its parent planet.
Billions of years ago, Mars suffered from numerous big impacts, and the resulting backwash ultimately scarred the surface of Phobos, one of the Red Planet's two tiny moons.
On Sunday, at 5:17 p.m. GMT (12:17 p.m. EST), Europe's Mars Express orbiter successfully completed a daring low-pass of Mars' largest moon Phobos. Continue reading →
In a daredevil flyby, the European Mars Express satellite will buzz Phobos, the red planet's largest of two moons. But there's a catch -- this isn't a photo opportunity.
Apparently Mars' moon, Phobos, was formed from rocks blasted off the Martian surface in a catastrophic event.
