Goddard Space Flight Center just released as open source a tool to perform space trajectory optimization and mission analysis. It appears to be quite cool.

The General Mission Analysis Tool (GMAT) is a space trajectory optimization and mission analysis system developed by NASA and private industry in the spirit of the NASA Vision. GMAT contains new technology and is a testbed for future technology development. To satisfy NASA's mandate and maximize technology transfer, GMAT is an open source software system licensed under the NASA Open Source Agreement.​
