The Probe-Class Mission Concept, CETUS
Sally Heap (GSFC)

CETUS is UV mission concept selected by NASA for study as a Probe-class mission (full life-cycle costs of $400M to $1B). The mission concept features a 1.5-m telescope with 3 scientific instruments: a near-UV multi-object spectrograph, a near-UV/far-UV wide-field camera, and a near-UV/far-UV point-source spectrograph. CETUS is by no means a poor man's Hubble Space Telescope. Instead, it focuses on doing things that Hubble can't do. CETUS will have the agility to respond rapidly to important astrophysical transient sources such as the UV afterglow of gamma-ray bursts or tidal disruption events. With its Goddard-made micro-shutter array, it will obtain spectra of ~100 faint galaxies at z~1-2 in a single shot. These spectra will help identify physical processes driving galaxy evolution at a turning point in the star-formation history of the universe. The point-source spectrograph will probe deep in the far-UV to study the multi-phase circum-galactic medium around galaxies -- likely the major repository of mass and metals in the modern universe.
