The Euclid satellite spacecraft is now officially an observatory: Euclid’s two instruments are seeing ‘First Light’ – recording the first engineering observations of the sky with a fully aligned and focussed telescope.

Updates and thoughts from the Euclid Project Scientist
René Laureiijs (ESA Project Scientist), March 2023
Finally, we now have a very firm launch interval, and it is approaching with light speed! We still have to tick off many boxes for the science operations, where a number of key operational activities must be defined in necessary detail. There is a large amount of work to be done related to the preparations for scheduling, processing, and analysis of the scientific (calibration) observations before the start of the Euclid survey. The daily science data rate in orbit will be huge and the timescales between the milestones are short, shorter than the time required to train completely new personnel. With a positive attitude, well-prepared teams, and good organisation we can meet our goals. There is certainly no lack of collaborative spirit and no fear of challenges, inherent to our ambition to break new scientific ground.

CMBX Science Working Group updates
Carlo Baccigalupi, Giulio Fabbian, Stéphane Ilic
Introductory Remarks
The Cosmic Microwave Background Cross-Correlation Working Group (CMBXC WG) in Euclid has achieved significant milestones since the previous Consortium Meeting in Oslo. The team is now getting ready for analysis, starting with Data Release 1 (DR1). The group plans to exploit existing CMB Datasets – Planck in particular – and to provide support to the Consortium in connecting with operating and future CMB observational campaigns. The activities of the group progress towards completion of the planned papers within the Key Projects (KPs) on (1) Simulations & Covariances, (2) Estimators, (3) Likelihood, and (4) Extended Forecasts, as described in the following. As the post-launch phase approaches, the group has been increasing its efforts in interfacing with the activities of the rest of the Consortium, in particular with regards to the Inter-Science Working Group Taskforce Likelihood (ISTL), as well as the Science Ground Segment (SGS).
