Q&A with Elon Musk, SpaceX’s founder and CEO

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).

A European Ariane 5 rocket climbed off its launch pad in French Guiana with nearly 3 million pounds of thrust Thursday, carrying two communications satellites to orbit for the Japanese military and British-based Avanti Communications.

NASA announced Monday that the launch of the first operational crew rotation mission to the International Space Station on SpaceX’s Crew Dragon spacecraft is set for the predawn hours of Halloween, eight days later than previously planned.
