Explore the fictional Iris System. Launch off and land on various planets and moons. (Iris is a green dwarf star.) There are two variables: Speed and Altitude. Speed shows how have fast you are going. If your speed is positive, you are going up. If negative, you are going down. Altitude is how far away you are from a given body. When landing, make sure your speed is -20 or more upon touchdown or you will crash.
