SPACE TELESCOPE SCIENCE INSTITUTE Operated for NASA by AURA TIPS / COS 27 June 2002

Keyes - 27 June 2002 Slide 2 of 8 Agenda   Overview   Instrument Activities and Status   STScI Ground System Activities – – “Back-end” (Pipeline, Archive) – – “Front-end” (Scheduling System)   User Support and Calibration

Keyes - 27 June 2002 Slide 3 of 8 Overview   Detector Status – – FUV flight detector now in scrub at UCB > > new QE grid installed; thermal cycling and vibration complete > > deliver to Ball in mid-July; integration in optical bench late July – – NUV flight detector on the shelf at Ball   COS Mini-Handbook: June 2002 (Ken Sembach, lead)   SI Environmental (Thermal-Vac): January/February 2003   SI delivery to GSFC: March 2003   Launch: March 2004 – – SM4 – – replace COSTAR

Keyes - 27 June 2002 Slide 4 of 8 COS Instrument Activities   SI News: – – backup FUV door-opening mechanism repair successful – – MEB functional tests completed – – QE grid wire on FUV flight detector discovered broken in detector Thermal-Vac re-test > > Replaced with thicker, more durable wire from new vendor (Stork- Veco); 35 x 12 microns (old wires 15 x 6 microns) – – NUV grating recovery successfully completed and closed – – FUV and NUV gratings 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-SPLIT positions

Keyes - 27 June 2002 Slide 7 of 8 COS Ground System   STScI Integrated Scheduling System Development – – GO WAVECAL, SAA contours, Flatfield exposures completed – – FP-SPLIT renamed FP-POS; updating in development – – AUTO WAVECALs in development – – Ops bench testing of STScI commanding will occur per Ball FSW availability timeline   OPUS/HDA and calcos – – All CDR Requests for Action completed; closure document published – – ICD-19 draft of COS pipeline output file headers and keywords

Keyes - 27 June 2002 Slide 8 of 8 COS User Support Development   COS Mini-Handbook – – Delivered to STScI User Support – – To be released with Cycle 12 Call for Proposals – – Provides observers with basic information about instrument capabilities available in Cycle 13   Bright Object Protection – – ISR in development - C. Leitherer, lead   Faint Standard Extension (FASTEX) evaluation – – FASTEX standards evaluated for use with COS – 2 are acceptable – – FUSE DD observations approved
