7	-- The next tree arguments (xVel,yVel,zVel) are the velocity of the space station.
8	-- The arguments (xRotAxis,yRotAxis,zRotAxis) are the rotation axis, with respect to which the space ship will rotate. Each argument can be 0 or 1.
9	-- The argument RotRate defines how fast the space station will rotate.
10	-- The arguments (xRotOnce,yRotOnce,zRotOnce) define in which direction the space station will face, if they are all zero, the station will face into the negative
11	-- z-direction, and the positive y-direction is the top side of the station.
