SMOV – Servicing Mission Observatory Verification
• Diagnostic check-out• New instrument start-up
– High-voltage ramp
• Repaired instrument recovery• Calibration
– Internal & external targets

SMOV Highlights
• Nearly everything is working great• Thermal situation very good• Could not recover ACS Solar Blind
Channel• NICMOS cooling is back• Jupiter interruption
