Soil samples collected by the MMX probe will shed light on the mysterious origin of the red planet's two moons, Phobos and Deimos. An international space mission aiming to collect sand and rock from one of Mars's moons is expected to land in Australia once the sample is retrieved. Japan launched a spacecraft towards Mars in a ground-breaking mission to bring back samples from the largest of the planet's two moons.
The five-year mission — the first to attempt to land on a Martian moon — could shed light on the origins of the solar system and life on Earth.
