Voyager Mission Operations Status
Report # 2012-06-08, Week Ending June 8, 2012
Command Transmission &
Verification Operations
Voyager
1 command operations consisted of the uplink of a Command Loss Timer Reset on 06/06
[DOY 158/1330z]. The spacecraft received
the command.
Voyager
2 command operations consisted of the uplink of seven bracketed Command Loss
Timer Resets sent on five-minute centers using 0.5 Hz steps on 06/06 [DOY 158/1627z].
The spacecraft received two of the seven commands sent.
Sequence Generation Operations
Data Return Operations
Voyager
1 Data Processing and Operations:
There were 40.6
hours of DSN scheduled support for Voyager 1 of which 14.3 hours were large
aperture coverage. One schedule support change made on 06/06 [DOY 158]
substituted 0.8 hours of DSS-14 in place of 1.8 hours of DSS-15/26 Array
support. The total actual support for
the period was 39.6 hours of which 15.1 hours were large aperture
coverage. There were no significant
outages.
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 June 8. The EDR backlog is 2 days.
Voyager
2 Data Processing and Operations:
There were 43.8 hours of DSN scheduled support for
Voyager 2 of which 30.4 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 2 days.
Flight System Performance
Voyager
1 performance was nominal during this report period.
Voyager
2 performance was nominal during this report period. Activity included switching from Gyros A
& C to B & C on 6/8 (DOY 160).
