  1. The next-generation Infrared astronomy mission SPICA Outline of SPICA Scientific Research Concept (SciReC) SPICA研究コンセプト概要 17th May 2010 Hideo Matsuhara & Takao Nakagawa (ISAS/JAXA) EAMA7

  2. SciReC : Table of Contents • Introduction • Adopted/ref. documents • Outline : scope of the SciRC • Definition of “Research product” • Assumptions / constraints • Research Concept • Management structure • Structure of Tracking/control & science ground segment • Observation & Operation Mode • Observing/Operational Duration • Data & Research products distribution • Data archive • Public Outreach • Observation Programs • Category of programs • Selection strategy of programs • Operation of observing programs • Propriety Time of Data

  3. Management Scheme(also described in SEMP)

  4. International Collaboration Scheme SPICA Steering Committee Science Advisory Committee • JAXASPICA team: System Integration Joint System Engineering Team FPI:FPC FPI : SAFARI FPI:BLISS FPI:MIRs+SCI Telescope • Korean Team (TBD) • NAOJ (TBD) • NASA • Team(TBD) • JAXA • Subsystem • Integrator • ESA • Subsystem Management • JAXA • Integration • (test @<10K) • SAFARI Consortium • System Integration • Japanese Group • ESA • Manufacturing • (test @ 80K) European Teams Japanese Teams ※ FPI : Focal Plane Instrument SAFARI : SPICA Far-Infrared Instrument MIRs : Mid Infrared Insturuments (MIRACLE,MIRMES,MIRHES) BLISS : Background-Limited Infrared-Submikimeter Spectrograph FPC : Focal Plane finding Camera

  5. Two-level management • Agency-Level Management (Steering or Executive Committee) • Manage the overall financial and programmatic issues • Authority to make the top-level decisions when required (impacting the whole cost, schedule, major risks, and scientific performance) • Project-Level Management • Technical Issues, Schedule, Reviews • SPICA JOINT PROJECT OFFICE • Joint Systems Engineering Team • Scientific Issues • Science Advisory Committee

  6. STEERING (or Executive) COMMITTEE (draft) • Purpose • Manage the overall financial and programmatic issues • Authority to make the top-level decisions when required (impacting the whole cost, schedule, major risks, and scientific performance) • Membership • Chair • JAXA representative • JAXA • JAXA/HQ representative, ISAS/HQ representative • ESA • ESA/HQ representative • SRON • SRON representative • Other national institutes (e.g. US, Korea) • Meetings • WHEN REQUIRED

  7. JOINT PROJECT OFFICE (draft) • Purpose • To manage the whole project efficiently • Technical issues, Detailed Schedule, Detailed Financial Issues, performance check • Membership • Chair • SPICA PI or PM • JAXA • SPICA PI, PM, SE, FPI chair, Each FPI PI • ESA • SPICA PM, PS, SAFARI Scientist, SAFARI PI, SAFARI PM • Other institutes (TBD) • Meetings • Monthly • Report to agency-level management structure

  8. Joint Systems Engineering Team (draft) • Purpose • To check technical issues focusing on I/Fs between subgroups • To avoid any “hidden gap” • Membership • Chair • SPICA SE • JAXA • SPICA PM, SE, FPI chair, Technical experts (including members from industry partners) • ESA • TBD (SPICA PM, experts, …) • Meetings • Every three months (together with design meeting) • Report to Steering committee

  9. Science Advisory Committee (draft) • Purpose • To review the scientific objectives and to check if the specifications and performance of SPICA is compatible with scientific requirements • Membership • Japan: Project Scientist, (SPICA PI as an observer) • ESA: Project Scientist • International member: scientist representing all relevant fields of astronomy (including SPICA Task Force in Japan) • Meetings • Every two months • Report to SPICA Steering Committee

  10. Management Structure(NEED TO BE UPDATED!!)

  11. Operation Plan

  12. Operation Centers (1) • Mission Operation Center (MOC) • In charge of the direct operation of the whole SPICA satellite system • Creating and sending commands • Receiving telemetry data • To check the health & basic functions of SPICA • Science Operation Center (SOC) • In charge of Observation Planning • Generate the observation plan, and deliver to MOC • Handling observation proposals, support the TAC (time allocation committee) decision for the observation plan • User Support: support users to plan observations and to submit proposals • Structure • HQ at JAXA • Instrument Control Centre (ICC) in Japan, Europe (& US, Korea)

  13. Tracking/control & science Ground Segment structure Science/HK/tracking data JAXA TT&C Ground Network Mission Operation Centre (MOC) TT&C data Observation Plan Science Operation Centre (SOC) ESA Space Operation Centre & Ground Station Raw/processed Data & toolkit SPICA users (Astronomers)

  14. Operation centers (2) • Science Data Center (SDC) • Management of science data, data analysis and archives • develop data analysis pipe-line and other related tools under the collaboration with each instrument team • Science data processing using pipe-line • Pointing reconstruction • Data distribution to observers • support astronomers’ scientific activity • Create data archives (both raw & and processed data) for public in collaboration with existing data centre (C-SODA at ISAS) • Structure • HQ at JAXA • Japanese SDC branch support Japanese users of SPICA • European SDC branch support European users of SPICA • (US, Korean …)

  15. Observation / Operation modes • Routine Operation mode • HK mode / Instrument C/O mode / STA focus adjustment / FoV Alignment verification / Orbit maneuver • Observation Mode • MIR imaging/spectroscopy • Coronagraph mode • FIR imaging/spectroscopy • Data transmission mode (in case of failure of HGA) • Contingency operation mode

  16. Phases of Operation • Launch & Early Operation (a few weeks) • Cruising Phase • A few weeks to a half year, to enter S-E L2 • Check-out Phase (until 6 months at most after launch) • Basic check-out phase (2 weeks) • PV Phase (a few months) • Test Observation Phase (a few months) • Nominal Observation Phase • Several proposal cycles • 2.5 years to achieve “Full Success” (incl. 6 months margin) • Observations to achieve “extra success” can also be executed so far as the “Full success” observations are not disturbed • Extra Observation Phase

  17. Observation Programs

  18. Category of observation programs • Performance Verification(PV) program • Calibration program • Guaranteed Time (GT) program • Open Time (OT) program • Director’s time (DT) program • a. b. : individual program is planned for each FPI’s evaluation / calibration • c. d. e. : program includes all FPI • Definition of “director” is tbd

  19. Time Allocation Issues(all numbers are tentative) TAC(Time Allocation Committee) is unique for all SPICA member countries, will manage time allocation in GT and OT. Member countries should have their own allocated % of observation time. • Engineering (calibration) Time: TBD (5) % • Director’s time: TBD (5) % • Including TOO observations • Guaranteed time for SPICA team: 20% • To be allocated as a function of “contribution” • SWG time ? Mission scientists’ time ? • Open Time for Member Countries: 50 % • Including Legacy Programs • each member country should have its own allocated time. • Open Time for General Community: 20%

  20. Proprietary Time • One year Proprietary time applies only to Guaranteed time & Open time (no proprietary time for Engineering, director time) • Start point: after Observers receive processed data • All the data after the proprietary time will be open for general community • Not only for member countries • Legacy Programs(not yet defined) • To be released when data processing is over ?
