Earth to Sky (ETS) is an exciting, growing partnership 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 have been funded by a series of NASA grants, the Earth Science Division of NASA's Science Mission Directorate, NASA's Office of Communications, and the NPS Climate Change Response Program, with significant in-kind contributions from both USFWS and NPS.
