Abstract

We introduce the CETUS probe-class mission concept by comparing it with a mission we already know: the Hubble Space Telescope. Hubble is a UV-optical-IR telescope. By design, it does things that only a telescope in space can do: it obtains exquisite images of astronomical sources unmarred by atmospheric seeing effects; and from above Earth's atmosphere, it observes UV radiation from astronomical sources. CETUS is an all-UV space mission concept, and it does things that only CETUS can do. The four main capabilities of CETUS that even Hubble doesn't have are: (1) wide-field (17.4'x17.4') imaging and spectroscopy of astronomical sources with £0.5” resolution; (2) spectral sensitivity to UV radiation at wavelengths as short as 1000 Å; (3) near-UV multi-object slit spectroscopy; and (4) rapid-response UV spectroscopy and deep imaging of transients like GW 170817; and (5) 23 times higher sensitivity to extended sources. Table 1-1 gives a full list of CETUS parameters and capabilities.
