PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 1998-11-06 NOTE = "MGS RST Instrument Health Report HEA8310A.TXT" END_OBJECT = TEXT END Miscellaneous ============= We have needed six SOPC reboots in the past four days to clear CD writer failures. A failure pattern seems to have emerged (at least for the recent events). We have documented that in ISA Z48906. Shortly after the ISA was submitted we had another failure; to make the required six copies of the MORS_0311 CD we will have had to reboot no fewer than three times. We have also contacted the JPL SA Office. Queries for both channelized spacecraft engineering data and channelized DSN monitor data failed on TdmsRead errors. We obtained about 2h 40m of spacecraft data and less than 35 minutes of DSN data. Because of time constraints, we will not resubmit these queries. ISA Z48907 has been submitted.
