Carl Biagetti/STScI
Timely Recommissioning of the HST Observatory for Science Operations
– Recommission existing SIs for science - WFPC2, STIS, FGS, NICMOS
– Commission the newly installed SIs for science – ACS
•
Recommissioning of Observatory Systems for normal operations
– PCS, EPS (PCU, SAIII)
•
Validation of other Orbital Replacements & Installations
– NCS, NOBL (TCS)
•
Early Release Observations (EROs)
– Demonstration of ACS & NICMOS science capabilities

V1 BRIGHT EARTH AVOIDANCE (BEA)
• Complete avoidance for first 12 days of SMOV
• Days 13 – 42, no more than 20% exposure to bright earth
– WFPC2 remains warm until after BEA period
– No WFPC2 pure parallels throughout SMOV
– ACS SBC HIGH VOLTAGE OFF FOR FIRST 30 DAYS
BEA SCIENCE
– SMOV3A - FGS & STIS SCIENCE PERFORMED WHERE POSSIBLE IN BEA
– SMOV3B – FEASIBILITY IS STILL TO BE DETERMINED

– Option to continue BEA
• Separate contingency plans for FGS & each SI

Carl Biagetti/STScI
• Plan is feasible and robust
• All SI teams are SMOV-experienced
• Plan is flexible wrt NCS/NICMOS uncertainties
– Key is cool-down characterization during BEA
• Data volumes, rates, and downlink requirements
– need close attention, prior to scheduling phase
–

capability, Alan Patterson, Jan. 2001
• Recommendation for dual-SSR usage at least during SMOV
