Windows on Earth is an educational project that features photographs taken by astronauts on the International Space Station.  Astronauts take hundreds of photos each day, for science research, education and public outreach.  The photos are often dramatic, and help us all appreciate home planet Earth.

This web site provides free public access to virtually all of these photos, updated at least weekly.  The site is operated by TERC, an educational non-profit, in collaboration with the Association of Space Explorers (the professional association of flown astronauts and cosmonauts).

CASIS (Center for Advancement of Science in Space) provided funds to develop and operate the site.

Windows on Earth also operates software on the International Space Station, as a window-side aide to help astronauts identify priority targets for photography.
