Mission set to blast off for Mars to grab a piece of its moon

A space mission is set to launch on Monday that will attempt to grab a piece of Mars' moon Phobos and bring it back to Earth.
If it is successful, this will become the first time a sample has been returned from Mars or its moons to be analysed in laboratories here on Earth.
It is hoped that the Mars Moons Exploration (MMX) mission, which is led by the Japanese Space Agency, will solve the mystery of how Mars's moons formed.
