Thales Alenia Space delivers Euclid communications module

Madrid, July 26th 2019 – Thales Alenia Space in Spain has delivered the communications module for the Euclid satellite to Thales Alenia Space’s Turin plant, where it will be integrated with the service module. Euclid is a European Space Agency (ESA) astronomy and astrophysics mission designed to help us better understand the nature of dark energy and dark matter. Thales Alenia Space in Spain is responsible for the communications system, while Thales Alenia Space in Italy is the satellite prime contractor, and also responsible for the service module.


Euclid will map the general structure of the Universe over 10 billion light years to show its expansion and growth during the last three-quarters of its history. The mission is designed to address two of the most important questions in cosmology today: How did the Universe originate and why is it expanding at an accelerating rate, rather than slowing down due to the gravitational attraction of its constituent matter?


Communicating at 1.5 million kilometers


Euclid will map the 3D distribution of up to two billion galaxies and associated dark matter during a six-year mission, covering most of the sky outside our Milky Way. The complete survey represents hundreds of thousands of images and several tens of petabytes of data. This huge amount of data will be transmitted by the satellite from its orbit around the L2 Sun-Earth Lagrangian point at a distance of 1.5 million kilometers from the Earth, using its K-band radiofrequency data transmission system. Euclid also incorporates an X-band system to control and monitor the spacecraft, and measure its distance to Earth.

According to Eduardo Bellido, CEO of Thales Alenia Space in Spain, “This program confirms Thales Alenia Space in Spain’s status as the European benchmark in communications subsystems. The delivery of the communications module marks an important milestone in the program. We are very proud to be playing a key role in one of ESA’s flagship programs to help us better understand the Universe.”

Thales Alenia Space in Spain is specialized in satellite communications, building on a long heritage in TT&C and data transmission systems for all type of space missions, including missions in low Earth orbit (LEO), geostationary orbit (GEO), lunar orbit and science missions orbiting around the L2 Lagrangian point (Herschel, Planck, Euclid, WFIRST, PLATO). Over the last 15 months, the company has delivered communications systems for 12 different satellites, including Sentinel 1, 2 and 3 (‘C’ and ‘D’ families), Meteosat Third Generation (MTG), Euclid and an export program comprising 3 Earth observation satellites.

Paolo Musi, Director of Science Programs at Thales Alenia Space in Italy, added “The development of Euclid is on track, with the ongoing integration and testing of the service module flight model in Turin, while the complete satellite structural and thermal model (STM) is ready for thermal qualification tests in Cannes. The Euclid program also reflects Thales Alenia Space’s strong presence in Europe, with outstanding contributions by our teams in Italy, Spain, Belgium and France.”

The Euclid service module has already begun integration and testing in Turin. The launch is planned for 2022, using a Soyuz rocket operating at Europe's Spaceport in French Guiana.
