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.

7. 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

8. 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

12. 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)
