  1. JWST Data Management Systems Gretchen Greene

  2. JWST Mission Hierarchy for DMS

  3. DMS Estimated Archived Data Volumes – Baseline

  4. JWST DMS Interface Context S&OC Project Level Agreements will be defined ~L-24mo

  5. JWST vs. HST DMS… Many Similarities, systems reuse (DADS, MAST), and lessons learned, however there are… • Key Basic Differences: • Order of magnitude increase in computational and I/O DMS throughputs • Flight Operations System interfaces to DMS will support direct transfer at STScI of DSN telemetry data and require priority data processing for Wavefront Sensing and Control • Functional Decisions: • As a result of Trade Studies, BOTH HST and JWST will be moving toward scalable distributed architecture • Data Processing Workflow Management system (OWL-CONDOR) • Dynamic Reprocessing of Data Products with CRDS • Online Data Product File CACHE • Higher Level data product generation assumed fundamental • Service based architecture to support multi-mission DMS

  6. MAST + JWST • STScI Archive Access systems include the intersection between the JWST mission operations & MAST • Distribution Services • Archive User Interface (MAST Portal) • User Authentication • Archive Catalog (CAOM) • Online Data Product Cache

  7. Multi mission Functional Architecture Overview – SDR1

  8. JWST SOC DMSRequirements and Design Phases • Completed formal Systems Level 4 Requirements • ~ 650 requirements for I&T verification • Beginning DMS I&T for internal Build 1 • Currently in year 2+ of design and development • Systems Design Review 2 – Dec 6-7, ’12 • Designing for Launch Readiness Data (LRD) 2018 with 95% level of current STScI DMS capability

  9. S&OC Science Systems Engineering, Flight Operations, and Systems Development Timeline for a JWST 2018 LRD

  10. DMS Build Plan
