SpaceX launch sends supplies to space station

A space capsule carrying a 3D printer to make human tissue and about 5,000 pounds of other experiments and supplies is on its way to the International Space Station after a thunderous SpaceX launch. Officials at biotech companies nScrypt and Techshot Inc say the mini-refrigerator-sized 3D printer will be controlled by scientists on the ground and print nerve cells, muscle cells and proteins.
