Adjust the parameters and launch the rocket into space - see if you can get a circular orbit! To play - set Gravity to some value, and then leave it there while you try to get a circular orbit by adjusting the launch parameters. Launch Time = how long the thrusters fire Launch Force = The acceleration given by the thrusters while firing Launch Rotation = The rate of turning of the rocket while it launches If you get close to a circular orbit, note the settings you used in the comments, change gravity, and try again for a new challenge!
My daughter is studying satellites, and I wanted to create a toy for her to experiment with to understand the challenges of reaching a stable orbit. The physics are totally not accurate. They do not represent any real world units, and gravity does not fall off with distance. Perhaps later, I'll experiment with adding more realistic parameters.
