Science Goals for a Sub-mm Space Interferometer

The aim of this workshop is to define the scientific priorities and technical requirements for a next-generation sub-millimeter/far-infrared space interferometer. By bringing together experts in astrophysics, space engineering, and mission design, we seek to lay the groundwork for a space-based array that can achieve groundbreaking observations of phenomena such as protoplanetary disks, black holes, active galactic nuclei, exoplanets, and cosmic masers. Through a concurrent design approach that encourages iterative feedback between science and technology, the workshop will catalyze the development of a scientifically ambitious yet technically feasible mission concept.

This interdisciplinary workshop will convene approximately 50–55 participants, including leading scientists, engineers, and mission planners from Europe, the US, and East Asia. The program includes plenary sessions, splinter meetings, and group discussions, rotating between scientific and technical topics to foster cross-disciplinary engagement. Participants will collaboratively define mission concepts capable of addressing the most pressing science questions in the sub-millimeter regime, while assessing key engineering challenges such as orbital configurations, receiver technology, and data transfer. The week-long effort will culminate in the initial drafting of a white book and the formation of a mission support network, providing the foundation for future studies and funding proposals.
