LISA mission
HEF photonique is proud to announce a new milestone in space exploration, with the launch of a collaboration with OHB-Italia to contribute to the LISA (Laser Interferometer Space Antenna) mission. This mission is led by NASA and ESA. The project is supported exclusively by ESA.
The aim of the LISA mission is to develop and implement a space detector capable of measuring gravitational waves in the frequency range from 0.03 mHz to 0.1 Hz. LISA will detect these waves and provide crucial data for understanding some of the most fascinating phenomena in the universe. HEF photonique will contribute its expertise in high-precision optical systems. The Group will supply the GRS optical windows for the satellite platform, into which the gravitational wave detector will be integrated. These optical windows are essential components for the transmission and detection of interferometric signals in space.
The collaboration between HEF photoniques and OHB-Italia will take place in two major stages:
-Technical qualification of the entire optical system, ensuring that all components meet the performance and reliability requirements necessary for a space mission.
-Production of the system, which will then be integrated and launched to a specific position in space: the Lagrange 1 point (L1). This point, located on the Earth-Sun trajectory, will be crucial in minimizing unwanted gravitational interactions, in order to optimize the precision of the measurements made by the detector.
The choice of L1, a stable point in the Earth-Sun system, will enable LISA to operate in an environment optimized for observing gravitational waves, free from disturbances caused by the movements of the Earth or other celestial objects.
The LISA mission represents a quantum leap in our understanding of the universe. It combines the latest technological advances in optical and space detection with ambitious scientific objectives. Through this collaboration with OHB-Italia, HEF Photonique is contributing to a large-scale initiative that could transform our vision of space and fundamental physics.
