It would seem odd that a spacecraft could seek the origin of fear and terror.

But that is the objective of Japan’s Martian Moons eXploration mission, a bold undertaking set to survey two oddballs circling Mars – the moons Phobos (fear) and Deimos (panic), name tags drawn from Greek mythology.

Phobos is 150-times smaller than Earth’s moon. Deimos in background is 280-times smaller than Earth’s moon and about half the size of Phobos.

Backed by the Japan Aerospace Exploration Agency (JAXA), this ambitious Martian Moons eXploration (MMX) spacecraft is headed for a 2024 sendoff. It will visit the two moons loaded with a rich to-do list.
