Earth Science Picture of the Day

Contributed by

Martin Ruzek, Universities Space Research Association

Educators and the science-attentive public are eager consumers of high quality, interesting, and informative imagery of the Earth. But imagery without explanatory background and context is of limited use in the classroom. Since September 2000, NASA Goddard Space Flight Center and the Universities Space Research Association have offered the Earth Science Picture of the Day (EPOD) web site, which is designed to serve as a repository of imagery, captions and web links highlighting the diverse processes and phenomena that shape our planet and our lives.

Each day the web site features a new Earth science image with a descriptive caption. EPOD's goal is to educate and excite people about the science of our planet. EPOD photos, imagery, drawings, animations, etc. exemplify features within the Earth system spheres of air, water, land, life and human dimensions.

We encourage contributions from all walks of life that show interesting, relevant, beautiful, or unusual aspects of the Earth - short captions and related web links are appreciated but not required. Contributors can submit their digital photographs using our semi-automated web-based submission (at the bottom of the EPOD home page). Editors filter and refine submissions from the community as necessary and seek additional content and relevant links.

EPOD aims to maintain an eclectic collection of imagery including field and laboratory photos, aerial photography and satellite images, complementing other excellent image repositories such as the NASA Earth Observatory and the Visible Earth. Image contribution and acknowledgement guidelines, and acceptable use policies can be found on the EPOD web page
