Title:

Our current understanding of the lunar electromagnetic environment

Speaker:

Masaki N. NISHINO (Nagoya University)

Abstract:

The Moon does not possess intrinsic magnetic field or thick atmosphere, but non-negligible parts of its surface are strongly magnetized. These features give rise to characteristic interaction with the solar wind plasma in a wide range of physical scales. Recent direct observations in orbit around the Moon by several spacecraft including Kaguya (SELENE) have brought us a lot of new information on the plasma and electromagnetic environment of the Moon. In this presentation, I review the latest results from observations of magnetic fields, plasma and neutral particles, and plasma waves, focusing on the interaction between the solar wind and the Moon. As the major phenomena of the solar wind-Moon interaction, (1) direct impact of the solar wind charged particles onto the lunar surface and their back- and forward-scattering, (2) plasma reflection and/or deflection above strong crustal magnetic fields, (3) several mechanisms of solar wind entry into the wake, and (4) their effects on wave excitation are presented.

Finally, the current status of BepiColombo, which is a mission to the planet Mercury, will be briefly mentioned.
