| Popis: | International audience; The Euclid mission is a cosmological survey mission to map the geometry of the Dark Universe and to understand the nature of Dark Matter and Dark Energy. Euclid will use two main probes for these purposes: Weak Lensing and Galaxy Clustering, measuring billions of galaxy shapes and millions of galaxies redshifts. Euclid will execute a wide survey covering part of the Extragalactic sky (15.000 degrees2) and three deep surveys near the ecliptic poles plus calibration fields. Mission planning is a key aspect to optimize the scientific return of the mission. There are a number of technical aspects that should be taken into account: restricted sky area at a given time due to spacecraft pointing constraints, Wide/Deep surveys and calibration interleaving, density of galaxies and stars, extinction, zodiacal light, CCD degradation, straylight, due to science payload constraints and constraints imposed by the galactic foreground components. The so-called Euclid Survey System (ESS) is the mission planning software infrastructure, developed by ESA at ESAC to support operational planning. This software has been already used to produce and evaluate several versions of the so-called reference surveys used to support other aspects of the mission. The Euclid Survey Planning System also has to interact with several actors: The scientific group in the Euclid Consortium in charge of designing the survey, the Instruments Design and Operation groups (IDTs/IOTs), ESA Operations Centre in Darmstadt (Germany), the Euclid Archive and it also needs also to produce reports which will help assessing the status of the survey and its level of scientific performance. |
