The Joint Astrophysics Nascent Universe Satellite (JANUS) is a proposed multiwavelength cosmic dawn science investigation. The mission's primary objectives are to: measure the cosmic star formation rate over the redshift range of 5-12, map the growth of massive black holes that seed galaxy formation at z>6, and enable detailed studies of the history of reionization and metal enrichment in the early Universe. Over the baseline mission, the wide-field X-ray Coded Aperture Telescope (XCAT; 1-20 keV) on JANUS is designed to localize high redshift (z>5) GRBs. After a prompt slew, the Near-Infrared Telescope (NIRT; 0.7-1.7 microns) refines the XCAT position by observing the early afterglow of each burst. The position, brightness, and redshift are telemetered to ground-based astronomers in real time. Concurrently, a wide-angle objective-prism survey of the entire extragalactic sky yields detection of high redshift quasars in the 6-10 redshift range.
