COPYRIGHT NOTICE

General
Generally, United States government works (works prepared by officers and employees of the U.S. Government as part of their official duties) are not protected by copyright in the U.S. (17 U.S.C. �105) and may be used without obtaining permission from NASA. However, U.S. government works may contain privately created, copyrighted works (e.g., quote, photograph, chart, drawing, etc.) used under license or with permission of the copyright owner. Incorporation in a U.S. government work does not place the private work in the public domain.

Moreover, not all materials on or available through download from this Web site are U.S. government works. Some materials available from this Web site may be protected by copyrights owned by private individuals or organizations and may be subject to restrictions on use. For example, contractors and grantees are not considered Government employees; generally, they hold copyright to works they produce for the Government. The Government is granted a worldwide license to use, modify, reproduce, release, perform, display, or disclose these works by or on behalf of the Government.

While NASA may publicly release copyrighted works in which it has government purpose licenses or specific permission to release, such licenses or permission do not necessarily transfer to others. Thus, such works are still protected by copyright, and recipients of the works must comply with the copyright law (Title 17 United States Code). Such copyrighted works may not be modified, reproduced, or redistributed without permission of the copyright owner.

If a recognizable person appears in a photograph or video recording, or the talent (such as a performance or narration) of a known individual is included in an audio or video recording, use for commercial purposes may infringe on a right of privacy or publicity. Permission should be obtained from the recognizable person or known individual. However, if the intended use of NASA material is primarily for educational or informational purposes (e.g., books, newspapers, and magazines reporting facts of historical significance), then such uses will generally not be considered an infringement of such personal rights.
