Success! SpaceX Dragon nails another in-flight mission

The International Space Station got a special two-ton delivery earlier today, as SpaceX's Dragon spacecraft capsule arrived at the station as it hung in orbit some 250 miles above the Great Lakes. The cargo included a space station docking port, needed for future rocket ships coming to the station. The port's arrival at the ISS has been a long time coming – a year ago similar docking rings were destroyed in a SpaceX launch accident. Scientists aboard the station eagerly received the latest shipment, using a robot arm. "We've captured us a Dragon," said astronaut Jeffrey Williams, the Associated Press reported.
