Since 2003, we have released more than 60 software projects under the NOSA.

The NASA Open Source Agreement (NOSA) is an Open Source Initiative (OSI) approved license to allow public release of NASA-funded software.
NASA has used open source to address project and mission needs, to accelerate software development, and to maximize public awareness and impact of our research.

The number of open source projects and amount of open source code is growing at an exponential rate and in some cases, allows work created for one project to be applied to another. Open source involves the joint production, release, and distribution of software that is freely and widely available. Perhaps the most exciting development has been the growth of open source software. For software developers this has led to new forms of collaboration and code reuse. The rapid growth of the Internet has changed how we use computers. 2010 – Source Forge modified Terms of Service for NOSA software distribution.2009 – Contribution License Agreement (for individuals and companies) for NOSA projects.2003 – Creation of the NASA Open Source Agreement (NOSA).The benefits of allowing the public to assist in development of NASA software include increased software quality, accelerated software development, and a higher rate of technology transfer both to and from NASA. This would shift our open source activities from its one-way direction of giving the public access to finalized software products, to allowing two-way collaboration as part of the development process.

Although open source release has already provided numerous benefits to NASA and the public, the full benefits of open source can only be achieved when we establish the processes, policies, and corporate culture to favor open source development. Its adoption by NASA also helps lower the barrier to entry into space by enabling private industry to better make use of NASA investments. Open source at NASA gives the public direct and ongoing access to NASA technology. The open source software movement is inherently transparent, participatory, and collaborative.
Contributions have involved the following: 1) lead development of add-ons, several of which have been integrated as part of the core system available for direct download via sourceforge, 2) lead provider of high-resolution data sets, 3) lead help desk support through Internet relay chat for end-users and developers, and 4) significant technical contributions to the core system including bug identification, tracking and resolution as well as ideas for new features and source code modifications.Open source development-which allows free access to software source code to allow anyone to make improvements-is revolutionizing the way software is created, improved, and used. This paper also describes the significant contributions of the international opensource community in making World Wind what it is today. World Wind is not only an application in which add-ons can be integrated, but is also being developed as a plugin that can be integrated with other applications. World Wind is also a customizable system that can be integrated as part of other applications. World Wind is a geographic information system that provides graphical access to terabytes of imagery and elevation models for planets and other celestial objects including satellite and other data of the Earth, Moon, Mars, Venus, and Jupiter as well as astronomical data made available through the Sloan Digital Sky Survey. This paper describes NASA World Wind, its technical architecture and performance, and its emerging use for mission operations.
