Abstract :
The LISA project of gravitational waves detection has been selected in January 2024 by the European Space Agency as the third ‘Large’ mission of the ‘Cosmic Vision’ program, with a expected launch date in 2035. This mission relies on the capability to measure, using laser interferometry, the distance fluctuations between satellites 2.5 Mkm apart, with a picometer accuracy on seconds to hours timescales.
LISA is the product of an international development effort, France being part of the European collaboration providing the instrument. In this context, the CNES and about fifteen French laboratories are contributing to the validation of the scientific performance of the instrument prior to flight and are currently developing the required high-precision optical metrology benches and measurement systems.
In this presentation we shall give an overview of the LISA instrument, its technical challenges and development schedule. We will focus on the validation strategy on ground, especially the demonstration of the interferometric performance in the mHz to Hz regime.
