Japan launches MMX probe to bring back a piece of Mars’s moon Phobos
JAXA launched the Martian Moons eXploration (MMX) probe on an H3 rocket from Tanegashima Space Center on 20 October. It aims to return at least 10 grams of Phobos to Earth in 2031.
Why in news
No mission has yet brought back material from a moon of Mars. Russia's Phobos-Grunt failed soon after its 2011 launch.
Prelims pointers
- MMX is led by JAXA, with NASA, ESA, CNES (France) and DLR (Germany) as partners.
- It is due to reach Mars orbit in August 2027, and its return capsule is to land at Woomera, Australia, in 2031.
- Near Phobos, it will fly in a "quasi-satellite orbit" and release the Idefix rover, built jointly by France and Germany.
- Asaph Hall discovered both Martian moons, Phobos and Deimos, in 1877.
- Phobos is the larger and inner moon and circles Mars in about 7 hours 39 minutes.
- Japan's earlier sample returns were Hayabusa (Itokawa) and Hayabusa2 (Ryugu).
Mains angle
Sample return is now a marker of space leadership. India's next step after Mangalyaan is mastering landing, lift-off and return.
