Copy of previously missed SPICAV & ASPERA science for redump.

377 20/11/06 324 213 Routine Mission operations.
Complete dump of missed science data.
378 21/11/06 325 214 Routine Mission operations
379 22/11/06 326 215 Routine Mission operations
380 23/11/06 327 216 Routine Mission operations
381 24/11/06 328 217 Routine Mission operations
382 25/11/06 329 218 Routine Mission operations.

Payload Activities

ASPERA
The instrument is regularly operated as part of the routine plan. All science data lost on DOY 329 was subsequently retrieved.

MAG
The instrument is regularly operated as part of the routine plan.

PFS
This instrument is OFF and is not operated.

SPICAV
The instrument is regularly operated as part of the routine plan. All science data lost on DOY 329 was subsequently retrieved.

VeRA
The USO is nominally powered but muted. There were no RSI activities during this reporting period.

VIRTIS
The instrument is regularly operated as part of the routine plan.

VMC
The instrument is regularly operated as part of the routine plan.


Mission Planning

Short Term Planning
Operations of STP030 were executed successfully and the planning of STP031 was completed in time.

Long Term Planning
A decision whether to request DSN support for the movie observation has not been taken yet.


Future Milestones

The second Earth occultation season will start in December with additional Radio Science operations with the ESA New Norcia station.

Planning of the entire Christmas period will be completed next week (STPs 34 through 37, plus MTPs 11 and 12).

An orbit correction manoeuvre is to be performed at pericenter passage on 15 December, followed by a touch-up manoeuvre on 21 December.
