The National Science Foundation (NSF) is offering a grant opportunity titled "Magnetospheric Physics," aimed at supporting research related to the magnetized plasma envelope of the outer atmosphere. This initiative encompasses various aspects of magnetospheric research, including the effects of solar wind, the origins of geomagnetic storms, and the interactions among the magnetosphere, ionosphere, and atmosphere, as well as ground-based observational programs and laboratory experiments relevant to the geospace environment. Proposals for this grant can be submitted at any time, with no cost-sharing or matching requirements, and interested applicants can find more information and contact support at grantsgovsupport@nsf.gov or visit the NSF program description at http://www.nsf.gov/funding/pgm_summ.jsp?pims_id=11725.
