RPC
The instrument was activated without problems as part of payload check-out 9 activities.
RSI
The instrument was unmuted and connected to the Telemetry, Tracking and Command (TTC) subsystem on DoY 040 for the check-out 9 activities. The procedure, which had some problems during check-out 8, was run successfully without problems.
VIRTIS
The instrument is OFF.
LANDER Philae
The instrument was activated without problems as part of payload check-out 9 activities.
SREM
Since DoY 026/2009 the accumulation settings are configured for active cruise mode.
Future Milestones
The active cruising phase will continue until March when Deep Space Manoeuvre 4 will be conducted in preparation of the third and last Earth swing-by planned for 13 November 2009.
The manoeuvre will be followed by a short tracking campaign with the spacecraft being configured for a near-Sun hibernation phase to last until beginning of September.
