Rockets are on the fast track to space.
A new, 50-foot magnetic levitation or maglev track demonstrates technologies that could dramatically reduce the cost of getting to space. At least not yet. But some high-tech roller coasters may already be using technology that could send future rockets flying into the great beyond. The technology is called magnetic levitation, or maglev. A maglev track uses magnetic fields to levitate and then 'push' a vehicle along a track at incredible speeds.
