SpaceX launches ISS docking port for NASA

SpaceX successfully launched a critical space station docking port for astronauts early Monday, along with a DNA decoder for high-flying genetic research. The company brought its leftover first-stage booster back to Cape Canaveral Air Force Station for a vertical landing – only the second such land landing for an orbital mission and the ultimate in recycling. Everything got off to a good start as the unmanned Falcon rocket streaked through the middle-of-the-night darkness, carrying 5,000 pound of food and equipment for the International Space Station. It was SpaceX’s second shot at delivering a new-style docking port for NASA
