1. SPACE TELESCOPE SCIENCE INSTITUTE Operated for NASA by AURA COS Monthly Status Review 22 January 2003

2. Keyes - 22 January 2003 Slide 2 of 6 STScI Integrated Scheduling System   Bench Timing Testing of Phases 1-5 completed (T. Wheeler) – – Essential for SMGT-readiness certification – – Target Acquisition FSW component not yet tested – – Unique Timing SMS and Reconfiguration SMS-suite > > FUV and NUV completed successfully – – STScI Commanding Certification SMS > > NUV completed successfully > > FUV Commanding Certification identified minor issue Hand-edited SMS ran successfully > > FUV testing requires FUV detector ETU > > Will re-test remotely (including Target Acquisition) within 6 weeks – – Testing and results are very positive!

3. Keyes - 22 January 2003 Slide 3 of 6 New Launch Date Impacts   Ground System Development – – SMOV4-related > > SMGT now planned for late June, 2004 > > Special commanding definition now required by September, 2003 COWG will establish requirements in spring > > Requirements (other activities e.g., on-orbit calibration) : definition Sep-Nov 2003 – – Revised STScI Phase Development Plan > > Includes new work items and updates

5. Keyes - 22 January 2003 Slide 5 of 6 STScI Calibration Pipeline Status  OPUS – – Successful testing with integrated SI data (from N 2 purge) – – Testing against latest DM-06 and Target Acquisition data suite planned – – COS Keyword Dictionary in preparation  CALCOS – – Most modules are now complete – – Successful testing with integrated SI data (from N 2 purge) – – Draft of ICD-47 is being reviewed

6. Keyes - 22 January 2003 Slide 6 of 6 STScI Thermal-Vac Support  STScI Coordination with IDT (STScI lead: Sembach)  OPUS support of Thermal-Vac – – MOU requires STScI to deliver T-Vac version of OPUS two months in advance of T-Vac – on-track > > Require test (simulator) target acquisition images 2-4 weeks in advance of this date if OPUS delivery is to include target acquisition functionality > > Minor T-V logistics issues being worked (e.g., additional k/w) > > Coordination ongoing with IDT – all nominal  STScI Staffing Support at T-Vac – – All STScI COS Instrument Scientists on-site on rotating basis
