Orbiting

I'm working on a world where two spaceships must orbit the Earth. One must be close to the
Earth and orbiting fast. The other must be far away and orbit slowly. The first one I have
done. But when I work on spaceship number two adding it to the call all it does is rotate
in place without moving. And if I add While to the call it ends up stopping the first
spaceship from orbiting. Can someone help me find what I am missing?
