Dragon docking

摘要

An unmanned Dragon spacecraft docked with the International Space Station on 3 March, arriving a day late because of thruster problems that were resolved. Built by California-based firm SpaceX, the space freighter carries supplies, equipment and scientific experiments. After completing its delivery - SpaceX's second - Dragon is scheduled to return and splash into the Pacific Ocean on 25 March, bringing back more than 1,300 kilograms of spent supplies and research samples.
