From nasaimages.org, a service of Internet Archive:

Internet Archive, NASA, and Flickr are together launching NASA on The Commons, a new way to view and interact with photos from NASA. NASA on The Commons invites the public to contribute information and knowledge to curated photo sets provided by nasaimages.org.  Visitors will be able to add tags, keywords, and annotations to three compilations of images curated by the New Media Innovation Team at NASA Ames and NASA photography and history experts across the Agency. The three collections, spanning more than half a century of NASA history, include: Launch and Takeoff, Building NASA, and Center Namesakes.

“NASA’s long-standing partnership with Internet Archive and this new one with Yahoo!’s Flickr provides an opportunity for the public to participate in the process of discovery,” said Debbie Rivera, lead for the NASA Images project at the agency’s headquarters in Washington. “In addition, the public can help the agency capture historical knowledge about missions and programs through this new resource and make it available for future generations.”

NASA on The Commons will make the NASA Images collection accessible to a wider audience while improving the information that accompanies these images with the help of the public.
