Abstract:
MISSION The purpose of NASA's Earth Observatory is to provide a
freely-accessible publication on the Internet where the public
can obtain new satellite imagery and scientific information
about our home planet. The focus is on Earth's climate and
environmental change. In particular, we hope our site is useful
to public media and educators. Any and all materials published
on the Earth Observatory
... are freely available for re-publication
or re-use, except where copyright is indicated. We ask that
NASA's Earth Observatory be given credit for its original
materials.
We encourage Earth scientists and science writers from all NASA
centers, as well as all agencies and universities affiliated
with NASA's Earth Science Enterprise, to submit articles and/or
images for publication on the Earth Observatory. Prospective
contributing authors and graphic artists should refer to our
Online Style Guide before submitting.
