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

The Russian Soyuz rocket that will carry a three-person crew to the International Space Station Wednesday has arrived on its launch pad at the Baikonur Cosmodrome in Kazakhstan.

Construction crews at Cape Canaveral’s Complex 40 launch pad are busily repairing and upgrading the facility after a SpaceX Falcon 9 rocket exploded there last year, with the pad’s return to service scheduled before the end of the summer, clearing the way for final preparations for the triple-core Falcon Heavy’s maiden flight late this year.

While a SpaceX Dragon cargo ship closed in on the International Space Station early Sunday, a Russian Soyuz spacecraft blasted off from frigid Kazakhstan, boosting a fresh three-man crew into orbit for a two-day flight to the lab complex.
