Herschel Status Report - April 2012

Report for period 5 April to 1 May 2012
Mission operations of the Herschel space observatory continued nominally during the reporting period, with the spacecraft and subsystems all performing as expected.
The spacecraft continues to be in good health and is operating nominally.
Operations for all three instruments, PACS, SPIRE and HIFI, have been nominal during the reporting period. Occasional HIFI single event upsets (SEUs) were routinely handled via standard procedures and had no impact on the observations. The efficiency of scheduling Herschel's observations remains high and the average time of executing observations (19.5 hours per day) remains well above the mission baseline of 18.0 hours per day.
Ground segment operations have been nominal and 100% of the data continues to be recovered. As of 27 April 2012, the approximate completion of the different programme parts was:
For more details of the different programme parts, see the "overview of Herschel observing" linked from the right-hand menu.
A routine station-keeping manoeuvre, or orbit correction manoeuvre, was performed on 27 April. These routine manoeuvres ensure the spacecraft maintains its correct operational orbit about L2.
