Earth to Sky (ETS) is an exciting, growing collaboration between the National Aeronautics and Space Administration (NASA), the National Park Service (NPS) and the US Fish and Wildlife Service (USFWS).

Together we work to enable and encourage informal educators and science communicators to access and use relevant science, data, and educational products in their work. The project began in 2004.

Earth to Sky efforts are currently funded by the Earth Science Division of NASA's Science Mission Directorate and NASA's Science Activation Program. Previous funding has come from a series of NASA grants, NASA's Office of Communications, and the NPS Climate Change Response Program, with significant in-kind contributions from both USFWS and NPS.
