Herschel Status Report - June 2012

Herschel Status Report - June 2012

Report for period 2 May to 20 June 2012Mission operations of the Herschel space observatory continued nominally during the reporting period, with the spacecraft and subsystems all performing as expected.

Spacecraft

The spacecraft continues to be in good health and is operating nominally.

Payload

Operations for all three instruments, PACS, SPIRE and HIFI, have been largely nominal during the reporting period. Occasional HIFI single event upsets (SEUs) were routinely handled via standard procedures and had no impact on the observations. A PACS anomaly affecting the instrument's blue channel necessitated the rescheduling of several science observations. The efficiency of scheduling Herschel's observations remains high and the average time of executing observations during the past year (19.3 hours per day) remains well above the mission baseline of 18.0 hours per day.

Ground Segment

Ground segment operations have been nominal and 100% of the data continues to be recovered. As of 15 June 2012, the approximate completion of the different programme parts was:

KPGT  Key Programme Guaranteed Time >99%
KPOT  Key Programme Open Time >99%
GT1  First in-flight Guaranteed Time 98%
OT1  First in-flight Open Time, high priority 85%
  First in-flight Open Time, lower priority 3.6%
GT2  Second in-flight Guaranteed Time 61%
OT2 Second in-flight Open Time, priority 1 26%
  Second in-flight Open Time, priority 2 0%

Mission Operations
Throughout the reporting period, mission operations have been conducted with the support of ESA's New Norcia ground station. Observational data stored on-board Herschel was received on ground during daily communication passes, each lasting approximately three hours.

Archiving
The ground segment is operating nominally. Data products are generated routinely and ingested into the Herschel Science Archive (HSA). On 15 May a new implementation of the HSA was released. It has been completely re-engineered to offer improved performance and better user experience using state of the art technology and higher code re-usability with other science archive projects at ESAC.

Future Milestones

  • Summer 2012: Completion of the fourth bulk reprocessing of all archived Herschel data
