NASA Voyager Mission Operations Status Report Week Ending January 12, 2007
![NASA Voyager Mission Operations Status Report Week Ending January 12, 2007](https://media2.spaceref.com/news/voyager.2.jpg)
Command Transmission & Verification Operations
Voyager 1 command operations consisted of the uplink of a command loss timer reset on 01/11 [DOY 011/0445z]. 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 01/11 [DOY 011/0517z]. The commands were not radiated due to a transmitter failure at DSS-43 [DR C105459].
Sequence Generation Operations
Continue sequence development of CCSL B135.
Data Return Operations
Voyager 1 Data Processing and Operations:
There were 37.3 hours of DSN scheduled support for Voyager 1 of which 19.0 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. One frame of GS-4 data was recorded this week. A second frame of GS-4 data was recorded on day 6. The EDR backlog is 2 days.
Voyager 2 Data Processing and Operations:
There were 54.5 hours of DSN scheduled support for Voyager 2 of which 10.8 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. One frame of GS-4 data was recorded this week. The PRA receiver recovered from its’ 98th POR event on January 12. 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 a PMPCAL 0n 1/9 (DOY 009).
