The Hera probe has swung around Mars, using the planet’s gravitational pull to fling itself toward its asteroid target.

The European Space Agency (ESA) fires up three of the instruments on the Hera spacecraft and takes images of the smaller ...

Computer simulations suggest that Mars' puzzling moons, Phobos and Deimos, may have been formed from debris created when a large asteroid wandered dangerously close to the Red Planet. This new ...

These moons, Phobos and Deimos, are believed to be either asteroids captured by Mars' gravity or debris from the early formation of the solar system, according to NASA. Phobos and Deimos ...

For an hour, HERA flew as close as 5,600 kilometers from the Martian surface, at a speed of 33,480 kilometers an hour. It ...

The Red Planet and its tiny moon Deimos were recorded at a very near distance as the asteroid-chasing spacecraft completed a ...

Mars has two moons, named Phobos and Deimos, but because Phobos is closer to Mars, it has been previously imaged by other spacecraft. "For Deimos, we don't have as many images as Phobos ...
