Instrument Development (FSW) DATE Y PROBLEMS/ISSUES PROGRAMMATIC IMPACT ACTION ESTAB. COMPL. Delay of FSW implementation for target acquisition (Build 4.0) Delays timeframe for testing our acq commanding and delays availability of subset of test image data Revised FSW development schedule implemented at Ball CURRENT STATUS Open  Tool is not mature enough for use in Cycle 11 Phase II Cycle 11 Phase II to be released Spring ‘02 (originally January ‘02) Evaluation underway (internal & external evaluators) look and feel GUI process model STScI front-end development completed; one-month Ball schedule slip this period (Sep 02 delivery); no impact on beta OPUS/HDA Delivery nor Thermal-Vac MOU schedule; now one month of float

Instrument Development DATE Y PROBLEMS/ISSUES PROGRAMMATIC IMPACT ACTION ESTAB. COMPL. None to STScI short-term; delays integration of FUV flight detector; IDT delay in MOU deliverables, T-V and SI delivery; additional long-term impacts possible IDT investigation: review of qualification procedures and test data; secure new grid; revise test procedures; utilize ETU for optical bench fitting activities; implemented repair and testing FUV detector QE enhancement grid breakage CURRENT STATUS Open  Tool is not mature enough for use in Cycle 11 Phase II Cycle 11 Phase II to be released Spring ‘02 (originally January ‘02) Evaluation underway (internal & external evaluators) look and feel GUI process model Investigation complete; fix identified, implemented, and integrated; detector scrubbed and testing proceeding; 4-week delay to SI schedule and MOU deliverables (STScI T-V support development); FUV install in optical bench expected late July.

Highlights - Accomplishments SI News: FUV flight detector QE grid breakage in detector T-V testing Detailed investigation conducted; full review of qualification and inspection procedures; modeling of material and test properties; design fix fabricated, installed, tested, and verified; re-scrub detector. Final vibration and thermal-vac testing of flight unit FUV01 to be performed in July; cumulative 4-week schedule impact. (continues yellow ) MEB functional tests completed successfully FUV and NUV gratings all installed on Optic Select Mechanisms (OSM) OSMs installed in COS optical bench OSM repeatability and stability accuracies require wavecal with each new central wavelength including FP-POS positions Completed and delivered COS Mini-Handbook Initiated SM4 SMOV requirements planning Joint effort with COS IDT

Highlights - Accomplishments (cont.) STScI scheduling system Phase 5 Scheduling System components FLATFIELD exposures and SAA contours completed on schedule AUTO “WAVECAL” exposures in code development; revision of FP-POS (formerly called FP-SPLIT) exposure capability Ops bench testing at Ball for all components per Ball FSW availability timeline (Aug 02) Phase 6 integrated schedule established Continued keyword review; established COS Association requirements Commenced Bright Object Protection requirements review Evaluated FASTEX Standards for use with COS 2 are acceptable; FUSE DD observations submitted and approved Established STScI COS public WWW pages

APPENDIX: Project Synopsis Role: STScI supports COS science operations by leading development of “front-end” (operations) and “back-end” (OPUS/MAST/calibration) ground system and user support functions. COS project is led by NISD, and presently consists of 12 people (7.65 FTE) drawn from NISD, SISD, and ESS. The project is on track (green) most recent report: 22 April 2002

APPENDIX: Resource Summary Current COS Resources (FY 02) NISD 3 Scientists (3.0 FTE) SISD 1 Data Analyst (0.5 FTE) ESS 1 System Engineer (0.5 FTE) 1 Command Development System Engineer (1.0 FTE) 1 Instrument Engineer (0.4 FTE) 2 Developers (1.25 FTE) Pipeline Development (1.0 FTE)
