SpaceX's Dragon capsule successfully docked at the International Space Station this morning, completing the first leg of its landmark supply mission. "Looks like we've tamed the Dragon," commander Sunita Williams quipped, as the station's robotic arm grabbed the capsule. "Thanks to everyone at SpaceX and NASA for bringing her to us … and the ice cream." Yes, among the almost 1,000 pounds of supplies the capsule brought was some chocolate-vanilla swirl, a last-minute addition and rare treat for the station crew, Space.com reports.
