Today when I entered the office I found a welcome present in my mail folder that made my day: David Roberts had sent me a patch to put our Marble Earth directly into the spotlight of our G2V Main-Sequence Star (also known as "sun" among non-astronomers). That's totally awesome because this feature will allow kde-edu users to visualize things like seasons. This feature always has been on my personal TODO but I haven't been brave enough yet to start work on it myself because it deals with the (non-trivial) texture mapping code. So I'm thrilled to see that someone else has started to work on this!
On another topic Claudiu Covaci has used the Marble Widget to create a small application for a student project at the university. It shows the orbits of some theoretical (GPS) satellite orbits around the earth. He does it by creating a Google Earth KML file from the orbital elements and by feeding it to the Marble Widget. He has also sent me a patch that removed the last few issues with little additional code required. As a result I also post screenshots of the satellite-KML in Google Earth and Marble. As you can see Google Earth fails to display the possible satellite positions for the hemisphere that is targeted away from the observer:
In the meantime Inge and me are working on the next bug fix release Marble 0.5.1.
