ESA Support to Hinode • ESA, in sub-contractual collaboration with the Norwegian Space Centre, provides • one additional downlink contact to Solar-B for each of the 15 orbits per day • This support considerably improves the overall scientific data return and the cadence of • observations from the Solar-B mission • The European scientific community is • catered with processed data through • a dedicated Solar B data centre • at the University of Oslo • MoU with JAXA • two European members on the Hinode • SWT were appointed this spring.
Svalbard Ground Station for Hinode • Reasons: • Possibility to track all 15 orbits per day • Antenna redundancy, and also strong • Norwegian interest • in the mission.
Aurora at Earth Jupiter Saturn
Mars plasma environment Solar wind Planetary wind • ASPERA • Characterisation of the planetary wind composition (atomic & molecular O+ ) away from the solar wind. • Solar wind scavenging of the atmosphere down to 270 km altitude, representing a major mechanism in neutral atmospheric degassing and past climate change. • Planetary heavy ions accelerated up to very high energies. • For the first time, ”radiation” of fast atoms is observed at Mars. • Current escape rate of Martian atmosphere (solar minimum). ≈100 ton/day Planetary wind (O+)

ILWSFuture Missions - SWARM • ESA - EOP Living Planet 3-satellite mission to study core dynamics and geodynamo processes, crustal magnetisation, and ocean circulation from low Earth orbit. • Ionosphere-magnetosphere current systems and magnetic forcing of the upper atmosphere need to be derived and taken care of - “one man’s noise is another man’s data” • Selected by Earth Obs. Program Board for Launch in 2009 (now 2010) • Electric Field Instrument (Ion Drift Meter) provided by CSA in collaboration with ESA Science Programme • For optimisation of GEOSPACE science capabilities an additional electron instrument “Conducto-meter” was discussed - but not achieved • Science operation and data products will be organised and shared between D/EOP and D/SCI (Definition process soon to be initiated)
PROBA - 2 ESA Technology Demonstrator Project for On-Board Autonomy within ESA D/TEC Successor of PROBA1 (launched in 2001, dedicated to Earth observation) ESA mission with Belgium as lead funder (through GSTP) Prime contractor: Verhaert Design & Devl. (Belgium) Schedule: development 2003-2006 and launch 2008 into an LEO 06-18 Sun-synchronous orbit Following a proposal to the ESA NLM programme the Proba-2 science operation has been «adopted« for a 2 year mission duration by the May 2006 SPC meeting - at a cost of 2.8 Meuro for ESA.

ESA’s Cosmic Vision, 2015-2025 Themes: • What are the conditions for life and planetary formation? • How does the Solar System work? • From the Sun to the edge of the Solar System (including the “hierarchy of scales” in plasma-physical processes) • Gaseous Giants and their Moons • The Building Blocks of the Solar System: Asteroids and Small Bodies • What are the fundamental laws of the Universe? • How did the Universe originate and what is it made of?
ESA’s Cosmic Vision, 2015-2025 Call issued in March 2007, Input due June 28 2007 Outlook from received Letters of Intent: In total 9 proposals in realm of ILWS expected (all M Class) 5 Solar missions already listed in Solar TG report 2 Magnetospheric 1 “IT” mission in margin of IT TG interest 1 Heliospheric missions (with long time frame) Downselection into 6 out of 64 expected proposals in 2007 Downselection into 2 flight opportunities - 1 M & 1 L Class after 2 years of competitive study in 2009/2010 Followed be AO for new slice of CV 2015-2025 “programme”. (formally there will be no programmatic approach…)
