Ultraviolet Explorer

Overview: The Ultraviolet Explorer (UVEX) is one of two missions selected by NASA to conduct mission concept studies as a Medium Explorer (MIDEX). NASA plans to select one Medium Explorer mission in 2024 to proceed with implementation. Launching no earlier than 2027, UVEX would undertake a synoptic survey of the entire sky in the near-UV and far-UV, probing the dynamic universe with a sensitivity more than 50 times better than GALEX. UVEX would also have a powerful broadband spectroscopic capability. UVEX would address fundamental questions from the Astro2020 Decadal Survey, and study the evolution of low-metallicity, low-mass galaxies. UVEX time-domain surveys could probe the aftermaths of gravitational wave-discovered compact object mergers, discover fast UV transients, and diagnose the early stages of explosive phenomena.

IPAC would provide the UVEX Science Data Center (USDC). Following the model of other missions supported by IPAC, the USDC would 1) develop data analysis pipelines in collaboration with the UVEX science team; 2) process the data to generate science-ready imaging and spectroscopic data products; and 3) provide real-time alerts to "brokers" for transient detections. USDC will also develop data analysis tools to support community use of UVEX data. IRSA will serve the data products, analysis tools, and documentation to the community.
