What happened

Japan aims for the moons of Mars Andrew Zinin Chief Editor Japanese scientists are readying a mission to Mars' moons to retrieve samples that may unlock the origins of the solar system and life on Earth, although a rival Chinese mission aims to make it back…

Why it matters

The unmanned Martian Moons eXploration (MMX), set to blast off from Tanegashima Space Center in the coming months, could also lay the groundwork for humans visiting the red planet.

Common ground

The spacecraft, revealed to the media last Thursday, will stay in Mars' orbit for around three years and will attempt to land on Phobos.
