- Fixed a few bugs in the user interface, which could result in display corruption when exercised.
- Scott Turner has taken over maintenance of JCSN.
- Add pre-Orbit insertion visualization (orbit number -1)
- Dust model for ring plane crossing is added
- 3D model has been discontinued
- Use Java Web Start technology. Using Java Web Start enable more efficient tool release and faster startup time. For first time user, please be patient. You have to download Java Web Start package from Sun Microsystem. Since JCSN is huge, initial download time can be long. However, once it is started, the tool is cached locally on your machine. When JCSN is activated the next time, the start up time is much shorter.
