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
