Mission operations of the Herschel space observatory continued nominally during the reporting period, with the spacecraft and subsystems all performing as expected. The second in-flight Announcement of Opportunity (AO2) process started on 7 April. It is the final AO for Herschel observing time.
This report covers 24 days of Rosetta mission operations. The main activities were the preparation of instruments for the hibernation phase, imaging the target comet and approach-phase sky with OSIRIS and the navigation cameras, and characterisation of the spacecraft's inertia properties and the Sun acquisition sensors.
Report for the period 27 February to 26 March 2011 (week 9 - week 12)
The reporting period, covering four weeks of Venus Express mission operations, was devoted to routine science activities. Twelve occultations were observed for Radio Science Investigations (RSI) campaign #10.
