  6. Synthesis Working Group • M. Blanc + M. Roos Serote + w.g. chairs + national groups representatives (when identified) • U.S. contact: R. Beebe (->former NASA w.g.) • Japan contact: M. Fujimoto (-> JAXA scientists) • Tasks: • coordinate proposal work project development –define milestones and timetable • Synthesize results and oversee interfaces/communications between w.g.’s • Discuss/make key decisions • Lead/finalize proposal drafting activity

  7. Working Groups I • EUROPA • JOVIAN SATELLITES • MAGNETOSPHERES • ATMOSPHERES • ORIGINS • Tasks: (1) scientific objectives, (2) measurement requirements, (3) science specifications for mission profile and s/c, (4) model p/l and resources, (5) iterations during proposal design

  8. Working Groups II • ORBITER PAYLOAD INTEGRATION • MISSION SCENARIOS • GROUND SEGMENT • SCIENCE OPERATIONS • KEY TECHNOLOGIES • OUTREACH

  9. Mission observation strategy Science questions vs. Observing modes Exobiology 3 Mag’spheres 4 Atmosphere 5 Origins 2 - Jovian satellites 1 - Europa Earth-based observations t.b.d. : JWST, ALMA, VLT, OWL, VLBI, etc Cruise science Dust streams, radio emissons, electron beams etc. Jupiter Equatorial Orbiter (JRS) JUNO (NASA) Jovian orbit JEO Europa Orbiter (JEO) Europa Orbiter Ganymede Orbiter ? Satellite orbit Europa « penetrator » Surface

  10. Mission design matrix Exobiology 3 Mag’sphere 4 Atmosphere 5 Origins Main Scientific Questions 2 - Jovian satellites 1 - Europa Mission Science Objectives Measurements Requirements Jupiter Equatorial Orbiter Europa Orbiter Jup. Atm. probe Mission Requirements Jup. Polar Orbiter Europa Orbiter Enabling Instrumentation

  11. Build from the outputs of previous meetings (Paris, Nantes, Berlin + ESA/NASA w.g. work) See integration document by N. André 1 – Characterize Europa as a planetary object & potential habitat Main Scientific Questions 1.1 Existence & characterization of a sub-surface ocean 1.2 Constraints on mantle dynamics & Silicate/ocean surface topography 1.3 Global surface morphology & dynamics 1.4 Surface composition and chemistry from orbit 1.5 Exosphere & Magnetospheric interactions Mission Science Objectives 1.1.1 Analysis of the static and tidal gravity field 1.1.2 Determination of the induced magnetic response from the ocean 1.1.3 Identification of tide-related surface motions 1.1.4 Determination of the amplitude of libration Measurements Requirements Earth-based Observations Jupiter Equatorial Orbiter Relay satellite Europa Orbiter Polar orbit Long-lived orbit Mission Requirements SC tracking 1.1.1 Micro-gravimeter, altimeter 1.1.2 Magnetometer (dual techniques, scalar) 1.1.3 Laser altimeter (resolution at cm scale) 1.1.4 Laser altimeter (resolution at cm scale) + Radio Science Deep Space Network Doppler tracking Enabling Instrumentation

  12. International collaborations • NASA : former ESA/NASA w.g. (adjourned during proposal time) • JAXA: strong interest expressed at scientific and mission devt. levels – Bepi-Colombo heritage is important there. • Science: U.S. and Japanese scientists in all science w.g.’s. One U.S. contact, one Japanese contact per w.g. • Mission: contacts with NASA (informal) and JAXA (formal) to explore cooperation scenarios • Mission design w.g. will include international partners + industrial support • MB to participate in Plasma physics conference next week in Tokyo, to meet with JAXA scientists, to visit NASA in november. Feed-back to proposal team.

  13. Let’s work together ! • All previous documents produced at team meeting and previous ESA/NASA meetings on web site: http:// jupiter-europa.cesr.fr • Home page for each w.g., with: • Keeping/updating of w.g. members list • Dedicated e-mail address for communication e.g., EJ-{w.g. name}.cesr.fr • Possibility of posting a document on the web page • Latest version of the draft posted there • Project assistant (Tania Tour) will: • Monitor all the activities together with the webmaster (Etienne Pallier), Maarten and me • Integrate your documents into the current version of the draft and the other documents • Keep up meeting information and help with their organisation
