Proceedings of the GRAvitational - wave Science&technology Symposium (GRASS) 2024, held in Trento (italy) on September 30th, October 1st and 2nd, 2024. 

The GRAvitational - wave Science&technology Symposia (GRASS) are a series of meetings held in Padova and Trento and aimed at exploring the panorama of gravitational-wave related experimental science beyond the next decade; special emphasis is given to open issues and key enabling technologies at the forefront of the most advanced detection techniques. It represents an informal and unique meeting occasion for experts from different fields involved in experimental aspects of future gravitational-wave science and technology.

The GRASS 2024 edition included topical sessions on Gravitational Waves and Multi-messenger Observational Science, Coatings and Materials, Perspectives for the Reduction of Quantum Noise and Stray Light mitigation for future GW detectors. A general session to discuss any other open issue was foreseen as well.
