CONT

The MMO spacecraft mainly aims the study of the magnetic field and magnetosphere of Mercury. ... Earth and Mercury have intrinsic magnetic field, but Mars and Venus do not. Why? Comparison of the Mercury's magnetic field with Earth's brings us the large step for the understanding of the terrestrial magnetic field and magnetosphere, and the magnetospheres in the various scales in the Universe.

OBS

BepiColombo, a cooperative mission by Japan Aerospace Exploration Agency (JAXA)/Institute of Space and Astronautical Science (ISAS) and European Space Agency (ESA), will explore Mercury, the planet closest to the Sun. ISAS/JAXA is building one of the main spacecraft, the Mercury Magnetospheric Orbiter (MMO), and ESA will contribute the other, the Mercury Planetary Orbiter (MPO).
