GSFC Open Source Software
GSFC conducts research and development in software and software technology as an essential response to the needs of GSFC missions. Under the GSFC Software Release policy, GFSC has several options for the release of GSFC developed software technologies. These options now include Open Source software release. This option is under the GSFC Open Source Agreement (NOSA).
NASA's primary goals in distributing software codes Open Source are:
- To accelerate NASA software development and improve the quality via community peer review
- To maximize the awareness and impact of NASA research
- To increase dissemination of NASA software in support of NASA's education mission
