SMOV4 PLANNING
CURRENT APPROACH
• Proceed with planning driven by Nov04
launch
– Requirements over the summer
• Less subject to rework in case of launch delay
• Project Requirements Review = 31July03
• ACS/NICMOS/STIS complete activity summaries by
Sep03
• Await confirmation or change of launch date
– Proceed with or rephase SMOV planning
accordingly

SMOV4 Planning Guidelines
The Generic SMOV Program
• A SMOV program is associated with each servicing
mission
• Generic SMOV goals
– Timely recommissioning of the Observatory for science
operations
• Commission newly installed science instruments
• Recommission existing science instruments
– Recommission Observatory systems for normal operations
– Validation of other on-orbit replacements & installations
– Early Release Observations
• Demonstrate upgraded science capabilities to astronomical
community and general public
Carl Biagetti/STScI

SMOV4 Planning Guidelines
Existing SIs
• ACS draft requirements:
http://www.stsci.edu/smov/smov4.html
• NICMOS draft requirements in work
• STIS draft requirements:
http://www.stsci.edu/smov/smov4.html
• FGS draft requirements in work
Carl Biagetti/STScI
12
SMOV4 Planning Guidelines
REQUIREMENTS PROCESS
• Determine SMOV tests/measurements
needed to recommission Observatory & SIs
(channel-by-channel)
– Goal to validate or augment ground-based
calibration data bases
– Ready Observatory for EROs and normal
GO/GTO science operations
• Circulate for SMOV team internal review
• Present to management review/blessing
Carl Biagetti/STScI
13
SMOV4 Planning Guidelines
REQUIREMENTS
• Determine engineering parameters that need adjustment or
measurement for commissioning
• Requirements statements should specify quantitative results
only where necessary for commissioning
– Define goals where appropriate
• Avoid explicit citing of CEI specs
• Determine special commanding needs ASAP
• Avoid implementation plans at requirements level
– Unless unavoidable
