Tutto bene durante le prime operazioni scientifiche condotte con gli strumenti di bordo di Venus Express. Ora la sonda europea può prepararsi ad entrare nella fase pienamente operativa della sua missione 😃

> Report for period 14 May to 20 May 2006
> 
> The reporting period is the first period during which all operations  
> have been executed according to the planning inputs received from the  
> Science Operations Center. All observations have been executed as  
> scheduled without any problem.
> 
> The planning cycle is now in its full operational configuration and all  
> the tools foreseen for the routine mission are in place. On 13 May  
> 2006,  
> at 13:33 UTC Venus Express had its 23rd apocenter passage and the first  
> science operations planned as part of the routine processes and with  
> the  
> routine tools have started. The process foresees a monthly planning  
> cycle (Medium Term Planning) when resources are checked and then  
> frozen,  
> and a weekly planning cycle (Short Term Planning) when resources are  
> finally checked and commands for the spacecraft produced for uplink.  
> This mechanism will be used throughout the mission.
> 
> The performance of the space and the ground segment during the  
> reporting  
> period has been nominal with some small problems recorded in the area  
> of  
> the Mission Control System. None of the observed problems, however, has  
> affected the mission operations.

> MET (Day) Date DOY Main Activity  
> 187 14/05/06 134 Routine Science operations  
> 188 15/05/06 135 Routine Science operations  
> 189 16/05/06 136 Routine Science operations, Uplink of STP002/2

> At the end of the last Cebreros pass in the reporting period (DOY 140,  
> 14:00) Venus Express was orbiting Venus at 165 million km from the  
> Earth. The one-way signal travel time was 553 seconds.

> ASPERA  
> The instrument is regularly operated. Some out of limits and warning  
> events have been recorded and confirmed to be expected by the PI team.  
> The database and the procedures will be updated accordingly. Upon  
> request from the PI team some observations have been modified in order  
> to avoid saturation of the sensor. A test of a specific acquisition  
> sequence is scheduled for the next reporting period.

> 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.

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

> VeRA  
> No operations have been executed in the 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. Sun

> Ground Facilities
> 
> During the reporting period Venus Express has been successfully

> Future Milestones
> 
> The phasing-in of the routine planning process is proceeding according  
> to the plan and no anomalies have been recorded. All the systems are  
> already in the configuration that will be used for the routine mission  
> which will officially start on 4 June with Medium Term Plan 002.
> 
> The first routine radio science operations will take place in the next  
> reporting period with activities scheduled with New Norcia and DSN  
> stations.
> 
> The next milestone for the mission is the preparation of the Mission  
> Commissioning Results Review to be held end of June.
