LAC Test Results / Actions
Thermal Vacuum (Before Spacecraft Integration):
- Instrument Operated for Approximately 40 hours
- Mount Temperatures < 25° C, Continuous Operation for 1 Hour
- Mount Temperature 30° C, Digital Board Overtemp. in 40 Min.
- No Modification: Maximum Operating Time In-flight 20 Min.
Thermal Vacuum (on Spacecraft):
- Instrument Operated for Approximately 30 hours
- Dark Current Consistent with Previous Results.
- Mount 40° C: Power Board Reached Red-limit Temp in < 5 Min
- Power Board Red-limit Set for Mount Temperature at < 30° C, Operational Constraint Consistent with Expected Conditions, Models Indicate Red-limit can be Increased by ~ 20° C
- Excellent TEC Control.
