Europe's Hera mission, on its way to the Didymos–Dimorphos double asteroid system, has performed a close flyby of Mars, receiving a crucial gravitational slingshot, testing some of its instruments, ...

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 ...

With its Thermal Infrared Imager, Hera snapped a picture showing the significantly warmer surface of Deimos versus Mars below it. This moon lacks an atmosphere and is pointed toward the Sun in the ...

The Red Planet and its tiny moon Deimos were recorded at a very near distance as the asteroid-chasing spacecraft completed a flyby on Wednesday. By Robin George Andrews Robin George Andrews wrote ...

A European spacecraft on a journey to study NASA's asteroid crash site did a quick pop-in of Mars on its way, capturing unprecedented images of Mars' lesser-known moon, Deimos. Mars has two moons ...

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 ...

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 ...

The Hera probe has swung around Mars, using the planet’s gravitational pull to fling itself toward its asteroid target. During its brief rendezvous with the Red Planet, Hera caught a glimpse of ...

On the way to investigate the scene of a historic asteroid collision, a European spacecraft swung by Mars and captured rare images of the red planet's mysterious small moon Deimos, the European ...

Deimos is tidally locked to Mars, meaning that like Earth's moon, it continually shows the same face to the Red Planet. Most previous images of the small, 7.7-mile-wide (12.4 kilometers ...

Martian moon Deimos seen crossing the face of Mars in this sequence of Thermal Infrared Imager images acquired during the Hera mission's gravity-assist flyby of Mars on March 12, 2025.
