Japan's Mission to Sample a Martian Moon and Return It to Earth

Japan has launched a spacecraft to explore the Martian moon Phobos and return a sample to Earth, an attempt not previously made. The mission aims to determine whether Phobos and Deimos formed from debris after an impact with early Mars or were captured asteroids from the outer solar system. The spacecraft is scheduled to arrive at Mars next year, deploy a small rover, land on Phobos, and return a sample in 2031.

■ Mission objective
- Investigate the origin of Mars' two moons
- Test whether they formed from impact debris or were captured asteroids

■ Spacecraft plan
- Arrive at Mars next year
- Set down a rover on Phobos to explore terrain
- Land the spacecraft and collect a sample
- Return the sample to Earth in 2031
