Euclid Reference Publications: the Euclid Mission Overview

Consortium, ESA, Publication, Science, Telescope and instruments / By

Euclid is a complex mission, consisting of a spacecraft and scientific instruments, a massive cosmological simulation, and large and complex data processing segment to turn instrumental data into scientific meaning. Now, one year after launch, the Euclid Consortium has published a set of five reference papers, providing both the scientific background and an up to date description of the instruments and simulations. Paper 1 (Euclid. I. Overview of the Euclid mission, Euclid Collaboration: Mellier et al. 2024) is giving a full overview of the Euclid mission after launch, ranging from the overall background, the satellite and instruments, the surveys, and finally introduces both the cosmology diagnostics as well as astronomy projects envisioned with Euclid.

In our mini-series about the Euclid Consortium’s set of new reference papers we are now turning to instrument descriptions: Paper 2 (Euclid. II. The VIS Instrument, Euclid Collaboration: Cropper et al. 2024) describe the VIS instrument, papers 3 and 4 (Euclid. III. The NISP Instrument, Euclid Collaboration: Jahnke et al.; Euclid. IV. The NISP Calibration Unit, Euclid Collaboration: Hormuth et al.) the NISP instrument.

Euclid Reference Publications: the Flagship Simulations

Consortium, ESA, Publication, Science / By

In our final post on the Euclid Consortium’s new set of reference papers we are turning to an essential part, the final ingredient to enable Euclid’s cosmology goal: Paper 5 (Euclid. V. The Flagship galaxy mock catalogue: a comprehensive simulation for the Euclid mission, Euclid Collaboration: Castander et al. 2024) is about the newly completed cosmological simulation, the Euclid Flagship Simulation, providing a fully-controlled input for testing and characterising the Euclid science pipeline.

Euclid de-icing campaign #2

Consortium, ESA, Telescope and instruments / By

As we have described before, there is humidity – water – in every spacecraft. And this humidity will turn to ice in the cold and vacuum of space. Euclid is no exception to this. If this humidity collects on optical surfaces like mirrors, it will affect the optical performance of a space telescope. For this reason Euclid will undergo a second targeted de-icing process over the next days.
