CHARISMA responds to the Committee on Astrobiology and Planetary Science (CAPS)'s recommendation to study a large/medium-class dedicated space telescope for planetary science. We are nearing the end of the Hubble Space Telescope lifetime, at which point the continuity of solar system UV measurements will be lost. Scientific objectives critically dependent on UV capabilities include studies of exospheric and auroral emissions in planetary atmospheres and plumes. CHARISMA will also revolutionize our understanding of time-dependent phenomena in our solar system currently not supported by programs intended to observe and visit new targets. The time-domain phenomena to be explored by CHARISMA include interaction of planetary magnetospheres with the solar wind, Venus and giant planet atmospheric dynamics, icy satellite geologic activity and surface evolution, cometary evolution, and evolving ring phenomena. CHARISMA also enables a comprehensive survey of the spectral characterization of minor bodies across the solar system, which requires a large time allocation not supported by existing facilities. CHARISMA will examine the benefits of advanced in-Space Assembly (iSA) technologies that enable a 10-m class aperture at New-Frontiers cost. CHARISMA will have the greatest impacts on science objectives particularly sensitive to dynamically evolving phenomena. |
