Two days after lifting off aboard a SpaceX Falcon 9 rocket from the Complex 40 launch pad at Cape Canaveral Air Force Station, a commercial Dragon supply ship loaded with more than 4,800 pounds of supplies and experiments arrived Sunday at the International Space Station. Capture of the robotic cargo craft occurred at 5:57 a.m. EST (1057 GMT).

A three-man crew led by six-time space flier Yuri Malenchenko rode a Soyuz rocket into orbit Tuesday, speeding away from a Kazakh launch pad on a six-hour chase of the International Space Station. Docking occurred at 1733 GMT (12:33 p.m. EST).
