MOSCOW (AP) — An unmanned Russian cargo spacecraft (similar to the one pictured here) has redocked with the International Space Station after an aborted attempt five days earlier. The Progress cargo ship had separated from the station a week ago to perform engineering tests and try out a new docking system and had been due to reconnect with the station on Tuesday. But problems developed with the avionics in the docking system. The second attempt early Sunday was successful. Video streamed from Russian mission control reported no problems.
