capturing unprecedented images of Mars' lesser-known moon, Deimos. Mars has two moons, Phobos and Deimos, but scientists know relatively little about them, especially the smaller one, Deimos.

Deimos is about 15,000 miles from Mars. Scientists have previously speculated that it may actually be a piece of asteroid, not a moon. Hera got as close as 1,000 kilometers, or about 620 miles ...

On a flyby of Mars, the European Space Agency (ESA) captured a rare photo of its second moon - but what do we know about it? It's called Deimos, and is much smaller and more mysterious than Phobos ...

ISAE-SUPAERO is actively collaborating in the international Hera probe program through the research work of Naomi Murdoch and the SSPA team. The probe, which is en route to study the asteroid ...

The Red Planet and its tiny moon Deimos were recorded at a very near ... An asteroid-chasing spacecraft just swung past Mars on Wednesday. As it zipped by, it took hundreds of shots of the Red ...

capturing the less-visible side of the tidally-locked moon. Deimos measures just over 7 miles across. Scientists believe Deimos could be a leftover chunk from Mars or a gravitationally captured ...

A space exploration mission to study an asteroid that NASA deliberately crashed a spacecraft into three years ago has taken stunning bonus images of Mars and its moon Deimos en route to its final ...

Like our moon, Deimos is tidally locked to Mars, meaning the same side always faces the planet—the only side visible to rovers on the Martian surface. The only way to see Deimos’ far side up ...
