Magnetometer group had the lead position
Extremely efficient international cooperation with TU Braunschweig and Imperial College London
Short development time(< 2 years)
Challenging thermal conditions around Venus(2 to 3 suns)
Design, manufacturing and qualification of theboom by the VEXMAG Team
Impressive science output
Modeling of MCs from in-situ data Reconstruction of magnetic clouds from multi-spacecraft observations
(e.g. STEREO) with a new method: non force-free, not prescribing the geometry Yields more accurate shapes, magnetic fluxes and axis orientations These act as constraints on models of coronal mass ejection initiation and their
propagation in the solar wind
Reconnection at the Sun Determination of magnetic flux change rates and of
amount of magnetic reconnection flux in solar flares from
observations to test standard flare models Comparison of total flare reconnection flux with magnetic
flux in MCs to understand the relation between the solar
source and the associated MC
Numerical Simulation of Magnetic Clouds (MCs) Code-Development for a numerical solution of the hyperbolic system of
ideal MHD governing equations Investigate propagation of MCs from the sun to Earth – interaction between
MC and structured solar wind Compare simulated parameters with observations; support for interpreting
observations
Solar-Planetary Relations
