At the end of the last Cebreros pass in the reporting period (DOY 216, 18:00z) Venus Express was orbiting Venus at 47.1 million km from the Earth. The one-way signal travel time was 156 seconds.
Payload Activities
ASPERA
On DOY 211, the instrument failed to boot up as commanded, and appeared to remain in Safe Mode. This caused all subsequent TCs related to the science run not to be executed, and thus the observation to be lost.
MAG
The instrument was regularly operated as part of the routine plan.
PFS
Following the completion of the planned tests last week, there has not been any further operation of PFS.
SPICAV
The instrument was regularly operated as part of the routine plan.
VeRA
Two Bi-Static Radar passes were scheduled during this period, on DOY 214 and 215. These BSR activities were the last ones for the year, all the others in the schedule having been cancelled due to the S-band attenuation problem.
VIRTIS
The instrument was regularly operated as part of the routine plan.
VMC
The instrument is operated as part of the routine plan.
Future Milestones
- VIRTIS Movie #2 scheduled in the second week of August.
- Low PLL bandwidth acquisition tests with LGA and S-band over NNO scheduled for mid-August.
