EUCLID Mission Status

 

Euclid is a European mission, built and operated by ESA, with contributions from NASA. Among its core objectives, Euclid will investigate the origin of the accelerating expansion of the Universe and the nature of dark energy, dark matter and gravity. Euclid was launched on 1st July 2023 with a SpaceX Falcon 9 from Cape Canaveral; after a period dedicated to performance verification of the spacecraft and instruments, the nominal survey started on 14th February 2024.

In this page we provide information on the status of the ESA Euclid spacecraft and survey; this information is updated on a daily basis.

The columns displayed below show the following values:

  • Wide Survey Area: area in square degrees of the Wide Survey covered by Euclid since the start of the Survey, 14th of February 2024. The Wide survey includes area visited once by Euclid and from where its main cosmological science will be derived. The number in this column represents the evolution of the Wide Survey only and it is composed out of the data ingested in the Euclid Archive System. It does not include other fields (deep fields) which are instead visited (observed) several times, nor calibration fields.
  • Number of VIS SRAW files: number of Science Raw files for the Visible Imager Instrument (VIS) acquired so far. Science Raw files include science data from several exposures taken during a pointing. Data is computed from the Euclid Archive System ingestions and considered for all the activities - wide, deep and calibrations - since start of Survey on the 14th of February 2024.
  • Number of VIS LE1 products: number of VIS Level-1 products extracted from the Euclid Archive System taken from start of the survey, 14th of February 2024. A Level-1 product contains the ordered and annotated data for an instrument exposure - on sky or calibration - ready to be processed further by the Science Ground Segment. Products are considered for all the activities - wide deep and calibrations - since the start of the Survey.
  • Number of NISP SRAW files: number of Pairs of Science Raw files for the Near Infrared Spectrometer Instrument (NISP) acquired. These files include science data from several exposures taken during a pointing. Two original files from the two processing units of the instrument are grouped into one zipped container. Data is computed from the Euclid Archive System ingestions and considered for all the activities - wide, deep and calibrations - since start of Survey on the 14th of February 2024.
  • Number of NISP LE1 products: number of NISP Level-1 products extracted from the Euclid Archive System taken from start of the survey, 14th of February 2024. A Level-1 product contains the ordered and annotated data for an instrument exposure - on sky or calibration - ready to be processed further by the Science Ground Segment. Products are considered for all the activities - wide deep and calibrations - since the start of the Survey.
