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
This instrument is OFF and is not operated.
SPICAV
The instrument is regularly operated as part of the routine plan.
VeRa
The USO has been unmuted on DoY 028 and 031 to conduct the planned Earth occultation observations. The two radio science observations have been supported by the New Norcia ground station.

Mission Planning
Short Term Planning
Operations of STP039 were executed successfully and the planning of STP040 was completed in time.
Medium Term Planning
MTP013 PTRs were delayed by one week.
Long Term Planning
A set of Long Term Planning products (FECS and Bit Rate File) were produced this week and delivered to the Venus Express Science Operations Centre for processing. The FECS file, contains the list of the downlink and radio science opportunities from the available ground stations.
Future Milestones
The definition and testing of operations during quadrature is on-going; the next quadrature phase will start in May 2007.
