Between the launch of Solar Orbiter (Februray 2020) and the end of the Cruise Phase of BepiColombo (2018-2025) various spacecraft mission will be operating at different radial distances in the Solar wind (as close as ~ 0.28 AU from the Sun up to Earth’s magnetosphere ~ 1.02 AU) such as: NASA/Parker Solar Probe, ESA/Solar Orbiter, ESA/JAXA BepiColombo, NASA/MMS, NASA/Artemis and ESA/Cluster. In order to coordinate the multi-spacecraft measurement during the cruise phase of BepiColombo, we have formed a working group. This splinter meeting will allow the working group members to meet, present and work thoroughly on the different planned tasks, such as, defining the scientific cases, modelling tools, measurement opportunities and related instruments operations.
