The Euclid mission aims at understanding why the expansion of the Universe is accelerating and what is the nature of the source responsible for this acceleration which physicists refer to as "dark energy". The mission will investigate the distance-redshift relationship and the evolution of cosmic structures by measuring shapes and redshifts of galaxies and clusters of galaxies out to redshifts ~2, or equivalently to a look-back time of 10 billion years....[+]
SENER concludes the manufacturing of the Euclid satellite assembly equipment13/02/2018 (Poland)
The engineering and technology group SENER has developed the assembly equipment for the Euclid mission, promoted by the European Space Agency (ESA). The delivery is composed of thirteen MGSE devices (Mechanical Ground Support Equipment), the last devices have recently been transported to Italy, where the mission probe assembly takes place.
The mechanical ground support equipment serve, among other things, to place the satellite accurately on different surfaces and thus helps the access to technicians. They also allow the satellite to be transported to test rooms and placed in the load area of the space shuttle. The production of the MGSE and the assembly of the satellites represent a great engineering challenge, inasmuch as all the satellites are unique in their kind. These constructions weigh from hundreds of kilograms to several tons and are made up of thousands of pieces and kilometers of cables.
SENER has designed, manufactured and analyzed thirteen devices for the assembly of a large satellite weighing 2.3 tons for the Euclid mission, which has recently been delivered to the main contractor of the mission, in Italy.
The participation of SENER extends to the Orbit and Attitude Control System (AOCS / GNC) in which it is the main contractor. The company also developed the secondary mirror refocusing mechanism (M2M) for this mission and is responsible for the design, production, integration, verification and validation of the high gain antenna deployment and pointing mechanism (HGA ADPM).
About Euclid mission
The goal of the Euclid mission, driven by ESA, is to understand why the universe expands at the pace we observe. The instruments of analysis of the probe will allow us to obtain a general view of the universe of the last billion years, which should give us the answer to that question.
EUCLID is a space mission to study the nature of the dark universe: dark matter and dark energy. To carry out its purpose, the mission will investigate the relationships between the distances, shapes, and redshift of cosmic structures and their evolution. To do this, a range of techniques will be used including Weak Gravitational Lensing (WGL) and Barionic Acoustic Oscillations (BAO), by combining observations from both a visual imager (VIS) and a near-infrared spectrometer and photometer (NISP).......

This award makes SENER the prime contractor for this AOCS subsystem that requires the highest level of performance, and for a ESA mission of utmost scientific importance providing further confirmation of the company’s leading position in highly complex AOCS/GNC systems for the science-technology market.[+]
