Japan launches MMX mission to retrieve samples from Martian moon Phobos
Key points
- Japan launched the MMX mission on an H3 rocket.
- The mission will retrieve samples from Phobos, a Martian moon.
- The expedition is expected to last five years.
- MMX seeks to understand Phobos's origin and Solar System formation.
MMX Mission Launch
Japan successfully launched its Martian Moons eXploration (MMX) mission on Monday from the Tanegashima Space Center. The MMX spacecraft was carried into orbit by an H3 rocket, Japan's flagship launch vehicle, which debuted a new configuration for this mission. The launch marks the beginning of a five-year expedition.
Mission Objectives
The primary goal of the MMX mission is to land on Phobos, the largest moon of Mars, and collect samples for return to Earth. This endeavor is a challenging international project designed to yield new insights into the formation of the Solar System. Scientists believe Phobos might be a captured asteroid, and MMX aims to verify this theory.
Technical Details and Journey
The H3 rocket's upper stage accelerated the MMX spacecraft to over 24,000 mph, allowing it to escape Earth's gravity for a 10-month journey to Mars. The nearly 9,900-pound spacecraft, with two-thirds of its mass being propellant, separated from the rocket approximately 71 minutes after liftoff. JAXA confirmed the spacecraft established contact and unfurled its solar panels, reporting it in a "very stable condition."
Legacy and Future Contributions
The MMX mission builds on Japan's previous successes with the Hayabusa and Hayabusa 2 missions, which were the first to return samples from asteroids. Japan's science minister, Yoshihiro Seki, stated that the results from MMX are expected to contribute to the nation's space science and exploration technology development.
