[PPS01-13] CHARISMA: A space telescope for planetary science
Keywords:volcanism, ring systems, small bodies, ocean worlds, ice giants, magnetospheres
CHARISMA’s 10-meter class aperture is enabled by advanced in-Space Assembly (iSA) technologies developed at NASA Langley Research Center (LaRC) and the in-space servicing technologies developed at NASA Goddard Space Flight Center (GSFC). The telescope will be robotically assembled in orbit and will adopt a sparse, distributed-aperture architecture, which is inherently modular in design and conducive to iSA. We will also examine the potential for future servicing and upgrades enabled by the iSA technologies. CHARISMA will take advantage of LaRC’s leading role in the Orbital Servicing, Assembly and Manufacturing (OSAM) efforts to perform a series of trade studies spanning a variety of variables. Our design will also utilize lessons from the on-going Astrophysics Decadal Mission Study of a future 20-meter in-Space Assembled Telescope (iSAT) that covers the same wavelength range as CHARISMA between FUV and NIR. CHARISMA will help mature the technologies identified by the iSAT final report to construct a 20-meter telescope. Thus, while serving as a fully functional, dedicated telescope for planetary science, CHARISMA also provides an early demonstration of key technologies needed for future astrophysics telescopes. The CHARISMA mission concept has excellent synergy with astrophysical facilities (e.g., JWST, ALMA and SKA). CHARISMA will be able to place planetary discoveries made by astrophysics assets in temporal context, and CHARISMA discoveries of time-dependent phenomena may trigger detailed observations using larger telescopes. CHARISMA will also support future missions to the Ice Giants, Ocean Worlds, and minor bodies across the solar system by placing the results of such targeted missions in the context of longer records of temporal activities and larger sample populations. The CHARISMA notional design, estimated cost, and science objectives will be presented.
