The NASA-sponsored Ultraviolet-Optical Working Group (UVOWG) has presented its report on the scientific rationale for new missions in the next decade. Outstanding unsolved problems focus on the theme ``The Emergence of the Modern Universe", studies of dark matter and baryons, the origin and chemical evolution of the elements, and the major construction phase of galaxies and quasars. Some key projects include mapping the cosmic web of intergalactic matter, measuring weak lensing at cluster scales, tracking the history of metal abundances, star formation, and stellar populations, probing host galaxies of massive black holes, and studying planetary systems through stellar occultations. The ST-2010 mission can address these problems with high-throughput UV spectroscopy and wide-field optical imaging on a 4.2-meter telescope with large-format, high-QE UV/optical detectors, and efficient optics, filters, and gratings. On a longer timescale, an 8m telescope with energy-resolving detectors (STJ or TES devices) offers tremendous power for UV/O space astronomy in the post-HST era.
