Finnish involvement in new ILWS missions

• BepiColombo • Solar X-ray emissions

• Solar wind - planetary interactions

• Solar Orbiter • Energetic particles

• Cosmic Vision 2015 – 2025 proposals• WARP (FMI lead, Tuija Pulkkinen)

• Cross-Scale (strong support)

• Participation in several other proposals (e.g.,IHP, EVE, Jupiter/Europa, …)

WARP: Waves and relativistic particles

• Four S/C constellation• 6000 km x 36000 km• equatorial (i 10 – 20 deg.)• 100 – 500 km separation

• Focus on details of the inner magnetospheric physics

• Full fields and particles suite on each satellite

WARP: Ultimate science goal

Understanding of the production of the MeV electrons in the inner magnetosphere

How do plasma waves drive electron and ion acceleration, transport and loss processes ?

How do the perpendicular and parallel current systems couple to plasma pressure anisotropies and gradients on the thermal ion scale ?

What is the role of the structuring of EM fields and low-energy plasma environment on the distribution of the most important wave modes ?

WARP and ILWS• Lead proposer: Tuija Pulkkinen, FMI

• Participants from: • Austria, Belgium, Czech, Denmark, Finland, France, Germany,

Greece, Sweden, UK

• a good overlapping with the Cross-Scale community

• Inner magnetosphere focus• different from Cluster, Themis, MMS, Cross-Scale, …

• Local 4-point observations• different from RBSB, Orbitals, ERG, Resonance,…

Miscellaneous• IHY

• Some PR activities

• e.g., IHY Open Doors Day, June 10,2007

• great success, owing to a simultaneous rock concert of 60000 audience in the same park

• IPY better recognized in Finland

• Health of ILWS science community• Active and relatively young science community with expertise from

solar eruptions to space weather effects on ground

• Problems with national instrument funding

• the next challenge: Solar Orbiter
