At the end of the last Cebreros pass in the reporting period (DOY 145, 18:00z) Venus Express was orbiting Venus at 122.5 million km from the Earth. The one-way signal travel time was 408 seconds.
Payload Activities
ASPERA
The instrument was regularly operated as part of the routine plan.
MAG
The instrument was regularly operated as part of the routine plan.
PFS
This instrument was OFF and was not operated.
SPICAV
The instrument was regularly operated as part of the routine plan. The SPICAV On-Board Control Procedure (OBCP) for the shutter has been tested and validated on ground.
VeRA
Occultation observations were performed over New Norcia on 2007-142 and 2007-144.
VIRTIS
The instrument was regularly operated as part of the routine plan. The VIRTIS software upload has been received at ESOC. Its validation on ground is ongoing at the moment. It is planned to implement it on-board just before the end of the quadrature phase.
Future Milestones
The swap to High Gain Antenna 2 will be performed on 1 June, DoY 152.
Special operations are planned during week 23, for the Venus flyby by NASA's MESSENGER spacecraft.
Quadrature phase operations will continue up to 16 June, DoY 167.
PFS tests are being prepared to try to move the scanner during a wheel off-loading (WOL).
