NASA astronaut on scrubbed launch: ‘You never know what day you’re really going to launch’

NASA astronaut Rex Walheim joined “Your World with Neil Cavuto” Wednesday to discuss the scrubbed launch of a SpaceX rocket that would have carried to NASA astronauts to the International Space Station.

“It’s a range of emotions during a launch day because you never know what day you’re really going to launch,” Walheim told host Neil Cavuto. “You have a scheduled launch day, but you don’t know what it’s going to be like. So you prepare and you prepare like you are here for the Super Bowl. But you don’t know what day the Super Bowl is on.

“So they’re used to this kind of thing and they know this is a possibility. So they’ll be able to head back to crew quarters, prepare a little bit more, get a little more sleep and be ready to go for the next launch,” Walheim added.

Astronauts Doug Hurley and Bob Behnken were scheduled to launch at 4:33 p.m. EDT from the Kennedy Space Center’s launch pad 39A, which was also used for the Apollo and space shuttle programs. What was to have been the first manned spaceflight launched from U.S. soil since 2011, was called off with 16 minutes and 54 seconds to go before liftoff.

The next launch attempt will be on Saturday at 3:22 p.m. EDT.
