1 SPACE TELESCOPE SCIENCE INSTITUTE Operated for NASA by AURA COS Monthly Status Review 15 January 2002

2 Cosmic Origins Spectrograph Monthly Status Review 15 January 2002 Charles D.(Tony) Keyes Page 2 of 11 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 11 people (6.65 FTE) drawn from NISD, SISD, and ESS. The project is on track (green) –most recent report: 20 November 2001

4 Cosmic Origins Spectrograph Monthly Status Review 15 January 2002 Charles D.(Tony) Keyes Page 4 of 11 Accomplishments SI News: –backup FUV door-opening mechanism repair installed, vibration tests successfully completed, final T-V tests in progress this week –NUV grating reflectivity; recovery plan nearing completion (continues yellow until completion) G185M delivered throughput below spec; G225Ma will be used as flight optic – throughput exceeds spec, increased spectral range; possible lower resolution G225M AlMgF coated optics below spec; bare Al coated flight-candidate optics in test at GSFC G285M AlMgF coated optics delivered throughput below spec; G225Mb is present flight optic – throughput exceeds spec, slightly decreased spectral range; higher resolution; bare Al coated G285M tests are even better; flight- candidate awaiting tests at GSFC G230L flight-accepted grating meets specification On-time STScI receipt of simulated FUV and NUV detector test images in internal header format (per DM-06); establish proper detector orientation; key MOU deliverable facilitates OPUS development

5 Cosmic Origins Spectrograph Monthly Status Review 15 January 2002 Charles D.(Tony) Keyes Page 5 of 11 Accomplishments (cont.) Evaluated responses to all OPUS/HDA and calcos CDR RFAs; revisions in progress; final closure document in preparation Established COS TV-specific keyword requirements and schedule Produced first ICD-19 working draft of COS pipeline output file headers and keywords; actionees identified for outstanding issues Established detailed ETC requirements; delivered to APT working group Detailed study of potential operational impacts of OSM heating in typical science scenarios STScI scheduling system –Development of FP-SPLIT exposure capability (last Phase 4 component) in final code review; on schedule Ops bench testing at Ball per Ball FSW availability timeline (Mar 02)
