STAR-X was proposed in December 2016 as a MIDEX mission for launch in 2023. It is an X-ray telescope with the following characteristics: (1) large field of view; (2) excellent uniform PSF in the entire FOV; and (3) large effective area. STAR-X will catch and study transients, including those resulting from mergers of compact objects, supernova explosions, tidal disruptions, and gamma ray bursts. STAR-X will also conduct surveys to study the growth of compact objects, including stellar mass black holes in the Milky Way and nearby galaxies as well as distant, high-redshift supermassive black holes. The capabilities of STAR-X also enable the study of hot, low surface brightness diffuse emission from galaxy clusters and supernova remnants. STAR-X is facilitated by a spacecraft bus capable of autonomous and fast slewing to targets of opportunity. In this paper we will describe the STAR-X mission design, technology, and major science objectives and its synergy with other major observatories in the 2020s, including eROSITA, JWST, WFIRST, and Athena.
