No. 79 - Entry into Quadrature20 May 2007 12:00 Report for period 13 May to 19 May 2007 The Entry in the Quadrature phase with fake ephemeris has been successful. The temperatures of all subsystems are also within limits. In order to perform science during this phase, a 17 hour cooling is required before any S/C communication. This has forced the missing of some of the passes at Cebreros. Not having sufficient passes to uplink all the commands, Venus Express is using, for the first time, the option of "delayed TC files" to store and call the commands on-board at a specific time.
During this reporting period only three passes were taken and the table below shows a chronology of the main activities for each pass:
At the end of the last Cebreros pass in the reporting period (DOY 138, 18:00z) Venus Express was orbiting Venus at 132 million km from the Earth. The one-way signal travel time was 441 seconds. Payload ActivitiesASPERA MAG PFS SPICAV VeRA VIRTIS VMC
