International Mercury exploration mission BepiColombo was launched in 2018 and will arrive at Mercury in 2025. During the interplanetary cruise phase, BepiColombo will range from 1.2 AU to 0.3 AU, and will stay in the inner heliosphere for long time. BepiColombo started its science observations during the interplanetary cruise phase in 2020. The initial results showed its enough performance to observe solar wind electrons, IMF, solar energetic particles (SEPs), and coronal mass ejections (CMEs) even in the composite spacecraft configuration. Especially in 2021 and 2022 two spacecraft of BepiColombo, Mercury Planetary Orbiter (MPO) and Mercury Magnetosphere Orbiter (Mio), successfully detected many solar events. BepiColombo can contribute to leading and expanding the heliospheric system science. In addition to BepiColombo, NASA’s Parker Solar Probe and ESA’s Solar Orbiter are also exploring the inner heliosphere. Coordinated observations between these multi spacecraft have been planned and performed. Ground based observations (interplanetary scintillation) and simulations (SUSANOO) can also be powerful tools to lead interdisciplinary studies. Here we present the overview and initial results of interplanetary cruise observations by BepiColombo.
