2 U.S. astronauts arrive at launch pad for SpaceX launch

CAPE CANAVERAL, Fla. (AP) — With thunderstorms and the possibility of tornadoes threatening a delay, two NASA astronauts climbed aboard a SpaceX rocket ship Wednesday for liftoff on a history-making flight that was seen as a giant leap forward for the booming business of commercial space travel.

Space veterans Doug Hurley and Bob Behnken were scheduled to ride into orbit aboard the brand-new Dragon capsule on top of a Falcon 9 rocket, taking off for the International Space Station at 4:33 p.m. EDT from the same launch pad used by the Apollo moon missions a half-century ago.

Smiling, waving and giving the traditional thumbs-up as Vice President Mike Pence looked on, the two men said farewell to their families — exchanging blown kisses and pantomiming hugs for their young sons from a coronavirus-safe distance — before setting out for the pad in a gull-wing Tesla SUV, another product from SpaceX’s visionary founder, Elon Musk.

Thunder could be heard rumbling as the convoy of vehicles made its way toward the rocket. And a tornado warning was issued moments after the astronauts climbed into their capsule.

The flight would mark the first time a private company sent humans into orbit.

It would also be the first time in nearly a decade that the United States launched astronauts into orbit from U.S. soil. Ever since the space shuttle was retired in 2011, NASA has relied on Russian spaceships launched from Kazakhstan to take U.S. astronauts to and from the space station.

With 2 1/2 hours to go before liftoff, controllers put the chances of launch at just 40 percent because of thunderstorms at NASA's Kennedy Space Center. In the event of a postponement, the next launch opportunity would be Saturday.

The preparations took place in the shadow of the coronavirus outbreak...
