Voyager: Mission Log (01-01-2010 - 01-29-2010)
Voyager Mission Operations Status Report # 2010-01-01, Week Ending January 1, 2010
Command Transmission & Verification Operations
Voyager 1 command operations consisted of the uplink of a Command Loss Timer Reset on 12/29 [DOY 363/1515z]. The spacecraft received the command.
There were no command operations in support of Voyager 2 during the period.
Sequence Generation Operations
Start sequence development of CCSL B147.
Data Return Operations
Voyager 1 Data Processing and Operations:
There were 90.2 hours of DSN scheduled support for Voyager 1 of which 63.9 hours were large aperture coverage. There were two schedule and one real-time changes made. The two schedule changes extended existing tracks. On 12/26 [DOY 360] the DSS-26/25 array track was extended 1.3 hours. On 12/29 [DOY 363] the existing DSS-14 track was extended 1.9 hours. The real-time change substituted on 01/01 [DOY 001] 6.8 hours of DSS-14 support for 6.8 hours of the array DSS-25/15 due to a red antenna at DSS-15 [DR G109907]. The total actual support was 93.4 hours of which 72.6 hours were large aperture coverage.
There was one significant outage of 0.5 hours on 12/29 [DOY 363] due to rain at DSS-63 [DR M105596].
Science instrument performance was nominal for all activities during this period. One frame of GS-4 data was recorded this week. A second frame of GS-4 data was recorded on December 26. The EDR backlog is 10 day.
Voyager 2 Data Processing and Operations:
There were 74.0 hours of DSN scheduled support for Voyager 2 of which 46.7 hours were large aperture coverage. There were no real-time or schedule support changes made or significant outages during the period. Science instrument performance was nominal for all activities during this period. The EDR backlog is 9 days.
