None to STScI short-term; delaysintegration of FUVflight detector; IDTdelay in MOUdeliverables, T-Vand 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
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
