SpaceX finally made good on its delivery of a space station docking port Wednesday morning, AP reported. A Dragon capsule arrived at the International Space Station, bearing more than 2 tons of supplies. The shipment includes a docking port needed for future rocket ships. SpaceX is working on a crew-worthy Dragon, while Boeing is developing a capsule for astronauts named Starliner. SpaceX launched its latest Dragon from Cape Canaveral on Monday. A year earlier, the first of these new docking rings was destroyed in a SpaceX launch accident. NASA and Boeing which makes the ports is working on a replacement that should fly in another 1 آ1⁄2 years. The two U.S. space station residents used a robot arm for Wednesday's 250-mile-high operation above America's Great Lakes.
