Japan's space agency JAXA has launched its Martian Moons eXploration mission, which aims to bring back a sample from Phobos, one of the two moons of Mars.
The mission also studies Deimos and the origin of the Martian moons.
A successful return would be among the first samples brought back from a moon of another planet.

How the exam will ask it
ಪ್ರಿಲಿಮ್ಸ್
- Phobos and Deimos are the two natural satellites of Mars; Phobos is the closer and larger one.
- The MMX mission is led by JAXA and aims to return a sample from Phobos to Earth.
- Sample-return missions bring material back to Earth for laboratory analysis, unlike orbiters that only observe remotely.
ಮೇನ್ಸ್
GS-III (Science and Technology: space technology, international missions). Sample-return missions help explain how Mars and its moons formed and what material lies near the Red Planet. For India, with its own Mars Orbiter Mission experience and planned deep-space ambitions, the way forward lies in international collaboration, building sample-handling capability and sustained funding for planetary science.
