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.
Solar System Missions Division
Reasons: Possibility to track all 15 orbits per day Antenna redundancy, and also strongNorwegian interest in the mission.

• 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.

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)

Project for On-Board Autonomy within ESA D/TECSuccessor 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:1. What are the conditions for life and planetary formation?2. 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
3. What are the fundamental laws of the Universe?4. 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 report2 Magnetospheric1 “IT” mission in margin of IT TG interest1 Heliospheric missions (with long time frame)
Downselection into 6 out of 64 expected proposals in 2007Downselection into 2 flight opportunities - 1 M & 1 L Class after 2 years of competitive study in 2009/2010Followed be AO for new slice of CV 2015-2025 “programme”.(formally there will be no programmatic approach…)
