Images from the Hera mission show the object in remarkable detail — a small island gliding above the crater-scarred Martian desert.

ESA's Hera spacecraft inaugurated use of its science instruments to image the smaller of the planet's two moons, Deimos.

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 the less-seen side of Mars’ smaller, tidally-locked moon as it orbited its home planet.
