Watch Ariane 5 launch with Star One D1 and JCSAT 15

Two days after blasting off from Kazakhstan, three new crew members docked with the International Space Station early Saturday to begin nearly four months of scientific experiments and maintenance on the orbiting research outpost. The Soyuz spacecraft linked up with the space station’s Rassvet module at 12:06 a.m. EDT (0406 GMT).

Ready for a resupply run to the International Space Station, a SpaceX Falcon 9 rocket was raised vertical at Cape Canaveral’s Complex 40 launch pad Wednesday ahead of a planned liftoff with more than 5,700 pounds of science experiments and crew supplies.

A Russian Proton rocket lifted off Thursday with a U.S.-built communications satellite to broadcast television over Latin America, firing into orbit from the historic Baikonur Cosmodrome in Kazakhstan.
