Space X's Dragon capsule has successfully splashed down in the Pacific Ocean after a month-long turn

Space X's Dragon capsule has successfully splashed down in the Pacific Ocean after a month-long turnaround on the International Space Station, having delivered a 3-D printer to outer space. It's the fourth of 12 resupply missions contracted to SpaceX, and having this one go off without a hitch is a good stepping stone toward manned flight , for a company that's had a few, ahem , reliability problems .
