UltraViolet EXplorer (UVEX) is a new NASA Medium Explorer mission to explore the ultraviolet sky, with an expected launch date in 2030. With a wide-field, two-band ultraviolet imager and long, multi-width slit spectrometer, UVEX is equipped to address key scientific themes identified in Pathways to Discovery in Astronomy & Astrophysics for the 2020s (Astro2020). UVEX will address outstanding questions in our understanding of the Universe, including the nature of the low-mass, low-metallicity galaxy population and the early ultraviolet emission of explosive transients. UVEX will also leave a rich legacy of all-sky ultraviolet data.
