Description
In this talk we address the measurement concept and the main experimental challenges for LISA, the first space-based GW observatory, to be launched in 2034. The task of using laser interferometry to measure the GW tidal deformation of a constellation of free-falling test masses is discussed, both in the context of heritage from the preparatory single-spacecraft mission - LISA Pathfinder - and for the unique remaining challenges to be met by the first orbiting GW observatory, whose location will allow the exploration of the mHz frequency band only accessible from space.
