SpaceX Dragon splashes down on Earth with space station cargo

A SpaceX Dragon cargo capsule splashed down in the Pacific Ocean at 2:51 p.m. EDT Wednesday, concluding a successful International Space Station resupply mission. MELBOURNE, Fla. -- A SpaceX Dragon capsule splashed down in the Pacific Ocean just before 3 p.m. ET Wednesday to wrap up a month-long visit to the International Space Station, returning to Earth with more than 3,700 pounds of equipment and science research. "The Dragon spacecraft has served us well," British astronaut Tim Peake radioed to mission controllers in Houston after the Dragon floated from the outpost in darkness at 9:19 a.m., released by its robotic arm. "It's good to see it departing full of science, and we wish it a safe recovery back to planet Earth." Among the 1,300 pounds of experiment on board were more than 1,000 tubes of blood, urine and saliva collected from former NASA astronaut Scott Kelly before his year-long ISS mission ended in March.
