Payload Activities

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

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

PFS
The instrument is currently OFF and is not included in the routine
planning. Next PFS tests in Venus pointing attitude are planned for the
first 4 orbits of MTP 6 (24-27 September 2006).

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

VeRA
The USO is nominally powered but muted. Occultation Observations with
USO un-muted took place on DOY 239 and 242.

VIRTIS

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

Mission Planning

Short Term Planning
Operations of STP17 have been completed successfully and the planning
of
STP18 was completed in time. A pre-check of the payload requests for
STP19 was also successful.

Medium Term Planning
MTP007 has been completed with no major problems.

Future Milestones

Throughout the next week short term planning for CP19 and pre-checks
for
CP20 will commence.

An operational strategy for the upcoming solar conjunction phase in Oct
/Nov 2006 is being further iterated.
