SMOV3B RESOURCES
• Observatory Resources
– Total external orbits = 419
• Not including 2-week BEA pointing
• SMOV Team
– STScI/GSFC/IDT/Ball
– Job well done, many long hours, not a “routine” SMOV
– 51 “morning meetings” Mar12 to Jul24 (165 days)
• average of one meeting every 63.5 hours (daily 1st 2 weeks)

TIPS 15Aug02
POSSIBLE OPERATIONAL
CHANGES (Spacecraft)
• Electrical Power System (EPS)
– Sun Incidence Angle constraint may be relaxed
• Since SA3 provides more power
– May involve sw upgrade but no science impacts
• Thermal Control System (TCS)
– Off-nominal roll constraint may be made more
restrictive
• Needed because Bay 5 is warmer post-3B due to
higher data volumes (SSR & xmitter usage)
• No significant impact to Cycle 11 yet identified
