Japan's MMX Mission to Investigate Mars Moons' Origin

• Japan's MMX space mission aims to investigate how Mars' moons, Phobos and Deimos, were formed.
• The Earth's moon formed from a collision with a small planet over 4 billion years ago, similar to the hypothesized formation of Mars' moons.
• The mission will study the composition and origin of the moons to understand their formation.
• The MMX mission is expected to launch in the mid-2020s.
• The findings from the mission could provide insights into the early solar system and planetary formation.
