Completed verification and validation of all commands and software patches required for IPS #4. Completed Earth Scan 18. Completed successful dry run of IPS #4. Measured optical cavity pressure of 8.8 E-06 Torr. Pressure has been reduced from 9.6 E-06 in the last 24 hours Successfully completed ACIS long form functional test and performed 5 hours of internal calibrations. Continued HRC calibration activities, but terminated them at the point where optical cavity pressure prohibited further increase in detector operating voltage. This activity will be resumed as pressure continues to decay. Events scheduled for the next 24 hours |
