NASA has a long history releasing code open source in support of its exploration mission. You may have heard about some successful NASA open source project before, like NASA WorldWind which has over 20 million downloads since 2005. One of the exciting projects currently being undertaken at NASA is an open source space mission design and analysis tool called GMAT - The General Mission Analysis Tool. Joel Parker from NASA’s Goddard Space Flight Center presented on the latest developments of the project today at the OSCON conference in Portland, Oregon. In case you missed it, I uploaded the slides here. For more information, visit http://open.nasa.gov.
