The Spanish company LIDAX has been selected by the European Space Agency (ESA), in collaboration with NASA, for a significant participation in the landmark LISA (Laser Interferometer Space Antenna) mission. The award of this contract underlines LIDAX’s recognised competence in the field of high-precision space engineering and its commitment to technological innovation. Its proven experience in highly complex space projects, including its contribution to the PLATO programme, positions LIDAX as an essential strategic partner to meet the rigorous technical challenges involved in a mission of the scale of LISA.
The LISA mission represents a pioneering space observatory designed for the direct detection of gravitational waves, disturbances in space-time generated by extremely energetic astrophysical phenomena. The detection of these waves, hitherto inaccessible to direct space observation, will open a new window for fundamental cosmological research.
Historically, astronomical exploration has relied predominantly on the analysis of the electromagnetic spectrum. However, LISA will allow information to be obtained from cosmic events that occur without significant emission of electromagnetic radiation, providing a complementary and crucial observational modality for understanding the dynamics of the universe in its most energetic regimes.
The LISA architecture comprises a constellation of three spacecraft arranged in an equilateral triangular configuration with an inter-satellite separation of 2.5 million kilometres. The detection of gravitational waves is based on the interferometric measurement of the infinitesimal variations in the distance between test masses inside each satellite, induced by the passage of the wave. These variations, in the order of picometres, require ultra-precision laser metrology between spacecraft.
In this demanding technological context, LIDAX assumes a critical responsibility. The Spanish company will be responsible for the development, manufacture and supply of CIPs (Common Interface Pedestals). These subsystems are highly stable interfaces that provide the connection and vibrational isolation of the sensitive components of the observatory, including the OBA (Optical Bench Assembly), where the optical and laser systems fundamental to the operation of the interferometer are integrated. The structural integrity and dimensional stability of the CIPs are essential parameters to guarantee the sensitivity and fidelity of the LISA measurements.
The award of this contract to LIDAX reflects its technical expertise and established track record in the development of state-of-the-art space instrumentation. Its previous participation in highly complex science missions and its involvement in the preliminary phases of LISA make it a first-class technology partner for the achievement of the mission’s ambitious scientific objectives.
The data that LISA will collect will allow the scientific community to address fundamental questions concerning the formation and evolution of cosmic structures, the physics of black holes in extreme regimes and the cosmology of the early universe, through the study of phenomena such as:
- The merger of supermassive black holes into active galactic nuclei.
- Compact binary systems of dense stellar objects.
- The stochastic background of gravitational waves of cosmological origin.
- Galactic binary systems for fundamental astrophysics.
LISA represents a paradigm in the exploration of the cosmos, transcending the observation based on the electromagnetic spectrum to go into the direct detection of space-time fluctuations. The scientific results derived from this mission have the potential to revolutionise our understanding of the universe and the physical principles that govern it, and the contribution of LIDAX stands as a fundamental element for the success of this momentous scientific project.
