Live coverage: SpaceX supply ship returns to Earth

Russian cosmonaut Fyodor Yurchikhin, on his fifth trip into space, and rookie NASA astronaut Jack Fischer, a Colorado native, blasted off aboard a Soyuz booster at 0713 GMT (3:13 a.m. EDT) Thursday from the Baikonur Cosmodrome in Kazakhstan, heading for the International Space Station for a four-and-a-half month expedition. The duo docked with the orbiting outpost at 1318 GMT (9:18 a.m. EDT).

The launch of a Russian Progress cargo ship aboard a Soyuz rocket was aborted in the final minute of the countdown Sunday, forcing a delay of at least two days in the start of a resupply and refueling mission to the International Space Station.

With three space station fliers heading home Sunday after a 168-day mission, three fresh crew members made final preparations for launch three days later to boost the lab’s crew back to six in a rapid-fire rotation that will prevent any major interruption of research activity.
