This program can be used to train people to spatial mechanics at an elementary level. You are given the power to launch a satellite, from outside the atmosphere, around a handful of predefined planets, or around any special object you may imagine. Input the initial velocity vector of the satellite, and you will get the simulated trajectory, as well as some information like the plots of variation of speed. As an extra, you can compute a movie, which represents the planet seen from the satellite's point of view during its orbital period.

The xwrited utility displays write(1) and wall(1) messages as desktop notifications. A notification daemon compliant to the freedesktop.org Desktop Notification Specification draft needs to be running in order to display the notifications.
