Here are two ways: (A) add a constructor to the Rocket class:

public Rocket()
{
    setRotation(270);
}

or (B) rotate the Rocket object after creating it in your World subclass:

Rocket rocket = new Rocket();
rocket.setRotation(270);

A zero rotation is always to the right. Rotation increases as you go clockwise. To "face" upward, an object must be turned three quarters the way around clockwise (3/4 of 360, 360 being a full circle, is 270). So setting an actor's rotation to 270 will have it face, or point, upward.
