If you've ever played the arcade game (or computer game) Asteroids, then you are somewhat familiar with what it takes to change the speed and direction of a moving object. It's not easy to do! In fact, getting high score on Asteroids may be a requirement for NASA aerospace engineers.

In the above animation, a telescope is traveling horizontally with a constant velocity. You can engage any combination of four engines that exert constant forces on the telescope. Engine A exerts a force in the -x direction, B in the +y direction, C in the +x direction, and D in the -y direction.
