CAPE CANAVERAL, Fla. (AP) — With thunder threatening a delay, two NASA astronauts have made their their way to the launch pad for the liftoff of a SpaceX rocket ship on a history-making flight to the International Space Station. The mission is seen as a giant leap forward for the booming business of commercial space travel. Space veterans Doug Hurley and Bob Behnken are scheduled to ride into orbit Wednesday afternoon aboard the brand-new Dragon capsule. It will be the first time in nearly a decade that the United States has launched astronauts into orbit from U.S. soil.
