1 Cosmic Origins Spectrograph Monthly Status Review 17 April 2001 Charles D.(Tony) Keyes Page 1 of 10 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 consists of 9 people (6.15 FTE) drawn from NISD, SISD, and ESS. The project is on track (green) –most recent report: 23 January 2001
