In response to NASA NRA NNH16ZDA001N-aprobes we propose to study the scientific return engineering design and estimated cost of a probe-class mission concept called cosmic evolution through UV spectroscopy (CETUS). The main features of CETUS are a 1.5 M aperture wide field-of-view (FOV) telescope with scientific instruments designed for ultraviolet (UV) imaging and spectroscopic surveys as well as single-object UV spectroscopy. CETUS' multi-object spectra and images will have 40 times the FOV of hubble's UV-sensitive camera and 10 times the collecting area and spatial resolution of galex enabling IT to advance UV astronomy in multiple areas. However the primary goal of CETUS will be to improve our understanding of cosmic evolution of galaxies and STARS. To maximize science return-to-cost CETUS is designed to make the maximum possible use of other telescopes particularly the prime focus spectrograph (PFS) to be installed on the subaru telescope. To show that these ambitious goals for both CETUS science and cost can be achieved we have assembled a world-class study team of scientists with expertise in cosmic evolution and engineers with experience in developing the newest techniques for efficiently designing fabricating aligning and integrating the components that will make up the CETUS space telescope.
