NASA on the Commons
NASA on the commons makes digital images available to the public spanning its history. They are using the Flikr platform, which is not entirely part of creative commons as Flikr users can put restrictions on their own work. The NASA images on the NASA page on Flickr are all noted as having no known copyright restrictions. The images include astronauts, craft, test sites, training, views from satellites and pictures from unmanned exploratory spacecraft. NASA does have caveats for comments, restricting use of URLs in comments to ensure there is no perception of commercial use.
