Update from the Euclid Project Manager

Updates and thoughts from the Euclid Project Manager

Giuseppe Racca (ESA Project Manager), March 2023

Following the major achievements of last year: 

  • Installation and test of four micropropulsion pressure regulators following several issues;
  • Repaired NIPS and VIS electronic units which had faulty circuit design, but no failure;
  • Integration of the High Gain Antenna, Sunshield, Service Module and Payload module;
  • Procured a new launch vehicle (Falcon9) following the discontinuation of Soyuz and A6 delays;
  • System test campaign at environmental and functional level, including SVT/SOVTs with the instrument operations, the MOC, the SOC and the IOTs;
  • Completion of the TBTV test and start of the mechanical tests;
  • Ground Segment Readiness review showing the readiness to support the launch in July 2023,

the acceptance tests of the Euclid system have continued in the first part of this year 2023

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.

Update from CMBX Science Working Group

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).

Science Performance Verification 3

The Euclid Science Performance Verification 3 meeting, March 2023

Authors: F. Bernardeau, P.-A. Frugier and H. Aussel (SPV3 leads)

From March 20 to March 23, a meeting dedicated to the third Science Performance Verification exercise (SPV3) took place at the Institut d’Astrophysique de Paris, France. Since the online kick-off meeting of the exercise, that took place in Feb. 17 2021, that was the first opportunity for key EC members of the SPV3 project to meet face to face. Unfortunately, in person participation was a bit hampered by the strike movements that affected Paris at that moment, but it was nonetheless a very lively meeting with up to 30 in person participants and about 10 to 20 online.
