2. Cosmic Origins Spectrograph Monthly Status Review 21 August 2001 Charles D.(Tony) Keyes Page 2 of 14 Synopsis Role: STScI supports COS science operations by leading development of “front-end” (operations) and “back-end” (OPUS/MAST/calibration) ground system. COS project is led by NISD, and presently consists of 8 people (5.15 FTE) drawn from NISD, SISD, and ESS. The project is on track (green) –most recent report: 19 June 2001

4. Cosmic Origins Spectrograph Monthly Status Review 21 August 2001 Charles D.(Tony) Keyes Page 4 of 14 Accomplishments SI News: –Flight detectors are available for both FUV and NUV that meet or exceed performance requirements –FUV flight spare detector integration continuing at UCB –backup door-opening mechanism repair and recovery plan implemented –NUV grating reflectivity below specification (continues yellow) G185M below spec; G225M can be used – lower resolution; vendor working G225M below spec; primary vendor evaluating fix; different vendor selected for mechanically-ruled alternate G285M OK G230L in fabrication; looks good
