SAGACE explores the sky in the 100-760 GHz frequency range, using four diffraction-limited bolometer arrays. The instrument is designed to perform spectroscopic surveys of the Sunyaev-Zeldovich effects of thousands of galaxy clusters, of the spectral energy distribution of active galactic nuclei, and of the [CII] line of a thousand galaxies in the redshift desert. In 2008 a full phase-A study for a national small mission was completed and delivered to the Italian Space Agency (ASI). We have shown that taking advantage of the differential operation of the Fourier Transform Spectrometer, this ambitious instrument can operate from a Molniya orbit, and can be built and operated within the tight budget of a small mission.Astrophysics - Cosmology and Extragalactic AstrophysicsAstrophysics - Instrumentation and Methods for Astrophysics Comment Proceedings of the 12th Marcel Grossman Meeting; Proc. of the 12th Marcel Grossmann Meeting on General Relativity Paris 12-18 July 2009, page 2133 (2012)conference paper10.1142/9789814374552_0426http://adsabs.harvard.edu/abs/2010arXiv1002.0867D2010arXiv1002.0867D
