PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 2002-12-03 NOTE = "MGS RST Instrument Health Report HEA2337A.TXT" END_OBJECT = TEXT END Errata ====== Data collected from occultation 16629i (DSS 65, start time 2002/331- 05:52:00) were incorrectly reported as lost due to a scripting error (HEA2336A.TXT). The data remain lost (or, at least, not yet found); but the cause is unknown. Miscellaneous ============= We have been unable to query for open-loop data collected at DSS 14, DSS 15, and DSS 63 on DOY 333/334. Aseel Anabtawi is currently investigating possible problems with playback resulting from competition with large volumes of incoming Cassini data. Dale Howell (LMCO) reports the spacecraft fuel and mass status as follows: For the period 2002/304 to 2002/337: ------------------------------------ 20.20801 Kg Hydrazine Remaining 5.26 kg Hydrazine Unusable 14.948 kg Usable Hydrazine Remaining 0.12853 kg used over last 33 days.

The carrier level returned to normal about 1.5 minutes before ingress. This measurement was also successfully captured by DSS 65. The last measurement captured on day 332 at DSS 25 (occultation 16649i, start time 2002/332-21:07:00) had a quick -1 dB dip in the free-space carrier amplitude over 5 seconds, followed by a +1 dB rise over 5 seconds that occurred about 1.5 minutes before ingress. Data collected on day 333 at DSS 65 (occultation 16653i, start time 2002/333-04:57:00) were lost due to a scripting error. This measurement was sucessfully collected at DSS 45, however.
