A better way to turn solar sails

83% Informative
Solar sails work by catching photons from the sun, much like wind fills a sailing ship's canvas.
Their enormous size compared to their mass creates a control problem.
Most spacecraft use spinning wheels called reaction wheels to change their orientation in space.
But solar sails are so large that these reaction wheels quickly become overwhelmed, spinning faster and faster until they reach their limits and can no longer function.
Researchers from the University of New South Wales have proposed an elegant solution inspired by Japan 's groundbreaking IKAROS mission.
