NASA, too, has open sourced
NASA just three months ago made its next generation mission operations software, MCT, open source! It's the real thing, certified for ISS (International Space Station) operations at Johnson Space Center in Houston. It will be used by the IRIS solar mission, and by some upcoming small satellite missions. It is a general purpose platform that can be used outside of the space operations domain. The demo version is trivial to install and run; be sure to add the plugins to see examples of how it can be extended. Search the internet for "open Mission Control Technologies." We post a new version every three weeks, and update our blog twice a week.
