## Japan prepares Mars moon mission
Japan is preparing to launch a five-year mission to bring back soil from Phobos, one of Mars' moons.
## Mission launch schedule
The spacecraft launches Tuesday morning in Japan, Monday afternoon in the United States, expected to reach Mars in August 2027.
## Mission goals
Scientists hope the samples will help solve how Phobos formed and shed light on Mars' smaller moon Deimos.
## Key scientist statement
Kiyoshi Kuramoto, Japan Aerospace Exploration Agency's principal investigator, said, 'We can almost certainly come to a conclusion by analyzing soil samples.'

## Theories on moon origins
One theory suggests Mars captured asteroids, but scientists have yet to explain how Mars kept them in stable orbits.
## Mission timeline
The mission will observe Deimos during its final phase and return samples to Earth in 2031.
## Key takeaway

Japan will launch a mission to collect soil from Phobos, Mars' moon, for the first time in history.
