The moons of Mars have been enigmas since their discovery. Phobos has a low orbit, about 3,700 miles (6,000 km) above the martian surface, and it zips across the martian sky in just four hours.

While on a flyby of Mars, Hera was able to use three of its imaging instruments to capture images of Deimos, the smaller of Mars' two moons, the ESA said. Deimos is about 15,000 miles from Mars.

At its current rate, Phobos will complete its death spiral and hit Mars in around 40 million years. But if tidal forces are already tearing the moon apart, then the satellite could be completely ...
