CAPE CANAVERAL, Fla. — A recycled SpaceX capsule is back at the International Space Station, just in time for Christmas. NASA astronauts used the space station’s big robot arm to grab the Dragon capsule out of orbit Sunday. It’s the second visit for this particular supply ship, which made a delivery for NASA back in 2015 as well, and only the second time a Dragon has had a repeat performance 250 miles up. “It’s a great day to see Dragon back at ISS again,” Mission Control radioed. Replied spaceman Joe Acaba: “It’s a beautiful spacecraft, and we’re looking forward to digging into it and getting some science on board.” Acaba assisted Mark Vande Hei in capturing the Dragon as the two spacecraft raced over the Pacific, midway between Australia and New Guinea.
