We are standing at the crossroads of powerful new facilities emerging in the next decade on the ground and in space like ELT, SKA, JWST, and Athena. Turning the narrative of the star formation potential of galaxies into a quantitative theory will provide answers to many outstanding questions in astrophysics, from the formation of planets to the evolution of galaxies and the origin of heavy elements. To achieve this goal, there is an urgent need for a dedicated space-borne, far-infrared spectroscopic facility capable of delivering, for the first time, large scale, high spectral resolution (velocity resolved) multiwavelength studies of the chemistry and dynamics of the ISM of our own Milky Way and nearby galaxies. The Far Infrared Spectroscopic Surveyor (FIRSS) fulfills these requirements and by exploiting the legacy of recent photometric surveys it seizes the opportunity to shed light on the fundamental building processes of our Universe.

在接下来的十年中，我们正站在地面和太空中，如ELT，SKA，JWST和Athena出现的强大的新设施的十字路口。将星系恒星形成潜力的叙述转化为定量理论，将为天体物理学中许多悬而未决的问题提供答案，从行星的形成到星系的演化以及重元素的起源。为了实现这一目标，迫切需要一种专用的星载远红外光谱仪器，该仪器能够首次提供大规模，高光谱分辨率（分辨速度）的多波长化学和动力学动力学研究。我们自己的银河系和附近的星系的ISM。
