Promoted through Flickr, the mission of NASA on The Commons is to make the visual record of NASA’s experience in “space exploration, scientific discovery, and aeronautics research” available to the public. The NASA images are actually housed digitally at the NASA Images Web site. NASA’s Media Usage Guidelines outline the limits of usage. NASA does make a distinction between commercial use and informational or educational use. Most of the content is already in the public domain and includes images and videos of human and mechanical space exploration, models and and maps, as well as digital media depicting the people and events that have shaped NASA’s legacy of memory on earth.
