The NASA Open Source Agreement (NOSA) is an OSI-approved software license. The United States National Aeronautics and Space Administration (NASA) releases some software (such as NASA World Wind) under this license. Publication of open source software fits in with Agency functions outlined under the National Aeronautics and Space Act, that is, to "provide for the widest practicable and appropriate dissemination of information concerning its activities and the results thereof." The NOSA was a point of discussion for NASA's Open Source Summit in March 2011.
