  1. Update of the French activitiesrelevant to ILWS Jean-Yves Prado, CNES

  2. Report from CNES • STEREO • PICARD • TARANIS • SMESE • Technical support to PHOIBOS proposal to Cosmic Vision • Data Issues • Back-up slides on MYRIADE ILWS Uppsala, 12 june, 2007

  3. STEREO • STEREO Space Weather beacon Ground Station => nov ’07 • new website Radio monitoring @ http://secchirh.obspm.fr ILWS Uppsala, 12 june, 2007

  4. STEREO Public Relations

  5. Phase C/D in progress • Launch planned for 2nd quarter 2009 PICARD Mission SOVAP PREMOS2 SODISM ILWS Uppsala, 12 june, 2007

  6. PICARD SCIENTIFIC PRODUCTS from orbit: - Diameter, limb shape and asphericity in the continuum - TSI (x2) - 5 spectral channels (215,393, 535, 607, 782 nm) - Activity (images at 215 nm and Ca II)=> space weather - Solar oscillations from the ground : - diameter, limb shape and asphericity, - local atmosphere turbulence ILWS Uppsala, 12 june, 2007

  7. TARANIS • Dedicated to understanding • Atmosphere/ionosphere/magnetosphere • coupling (sprites, elves, blue jets…) • Microcameras + photometer -MCM-CEA (+JP) • EM measurements -IEM- LPCE (+PL,TCH) • X-gamma Detector -XGD- LANL (USA), DNSC (DK) • Detector of high Energy ElectronsCESR (+TCH) • Quasi Sun Synchronous Orbit (2hrs LT drift/year) • Phase B will start in september • Launch expected for 2011 ILWS Uppsala, 12 june, 2007

  8. TARANIS OBJECTIVES Description - characterization of the sprites and associated emissions, measurements of their occurrence frequency and of their distribution at the scale of the earth. (caméras, EM waves, X and  spectra, high energy electrons) - study of the effects of the magnetic latitude and volcanic activity Implied mechanisms - determination of the nature of the triggering phenomena(cosmic radiation) - determination of the source mechanisms(EM waves, X and  spectra, high energy electrons) - study of the nature of the explosive dissipation of energy in the ionosphere and magnetosphere(EM waves, X and  spectra, high energy electrons) Global impact - determination of the effects on the upper atmosphere, ionosphere and magnetosphere(EM waves, high energy electrons, associated ground based measurements, other satellites) - evaluation of the coupling atmosphere -  ionosphere - magnetosphere and inter-planetary medium ILWS Uppsala, 12 june, 2007

  9. SMESE LYOT DESIR HEBS • Phase A ended (PRR) on 7 june, 2007 • Launch objective 2012-2013 ILWS Uppsala, 12 june, 2007

  10. SMESEpayload required performances ILWS Uppsala, 12 june, 2007

  11. SMESEFirsts • First combined imaging (disk, corona) in Ly  with high time resolution and sensitivity to trace the development of CMEs in the low corona + first polarimetric corona measurements, • First ever measurements of solar flares in the far infrared, key range for relativistic leptons and chromospheric plasma heated during flares, • First hard X-ray/gamma ray spectrometry at the highest energies ever attained with a solar-dedicated instrument, to study the most energetic electrons and nuclear processes in the Sun’s atmosphere. ILWS Uppsala, 12 june, 2007

  12. PROGRAMMATIC SCHEME PICARD SMESE TARANIS ILWS Uppsala, 12 june, 2007

  13. Technical support to PHOIBOS proposal • Following an open AO to the French Scientific community • Mission scheme • See presentation at IHY 2nd European General Assembly (Turin, 18-23 june) ILWS Uppsala, 12 june, 2007

  14. Data Issues • Support from CNES to thematic data centres (CDPP, MEDOC) • Data sets from CNES supported missions/instrument data + some others • Support to development of tools • POC: contact C. Jacquey @CDPP, K. Bocchialini @MEDOC • Data policy for PI missions : OK for openness, rapidity on a case by case basis • quality/reliability issues • priority to the PI for use of data • matrix of access rights defined by Scientific Committee of the relevant mission • Typicaly: Mission PI/CoIs all rights on all data • Instrument Co-Is, Guest Investigators restricted rights • Public: access to all data after a TBD delay (6 months to 2 years) ILWS Uppsala, 12 june, 2007

  15. MYRIADE SERIES • More than 20 spacecraft based on the same bus and systems • in flight or in preparation Bus waiting row 60x60x50 cm bus S-Band TTC (Kiruna/Toulouse) ILWS Uppsala, 12 june, 2007

  16. MYRIADE CAPACITY • Orbit inclination > 20° • Altitude 600km< >1000km • DNEPR launcher as the reference • Geocentric, inertial, solar or along the velocity vector pointing • Pointing precision of 0.1 ° (actuation), 5.10-3° (knowledge) • Attitude control system in nominal mode uses a stellar sensor, four reaction wheels and three magnetic torquers • up to 80 kg mass allocation to the P/L (when no propulsion/TM-X) • Power available to the P/L > 60w (highly orbit dependant) • Mass memory 16 Gbits • S-Band 400 kb/s as baseline ILWS Uppsala, 12 june, 2007

  17. MYRIADE OPTIONS • propulsion DV ~80 m/s (DEMETER, TARANIS…) • X-Band telemetry (>a few Gbits/day) TM rate 16-50 Mb/s depending on the ground station G/T • additional sun pointing device (PICARD, LYOT/SMESE) • quick deorbit kit under study ILWS Uppsala, 12 june, 2007

  18. A few examples of the MYRIADE versatility • DEMETER, TARANIS waves and particle instruments • PARASOL Lidar for atmospheric science • PICARD, SMESE Solar observation • MICROSCOPE Fundamental physics • ARGOS Localization • ESSAIM, SPIRALE, ELINT Defense • … • commercial availability of the bus (ASTRIUM, AAS) DNEPRlaunch ARIANE 5 launch ILWS Uppsala, 12 june, 2007

  19. FURTHER INTERNATIONAL COOPERATION Earth Observation as a paradigm? • a unique object, many possible instruments • curiosity driven science in competitition with monitoring science • shift from mammoth s/c (ENVISAT…) to series of small specialized satellites A Solar Train? ILWS Uppsala, 12 june, 2007
