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!
