SpaceX, NASA close to historic launch: 'The hatch is closed'by James Rogers
SpaceX and NASA are in the final stages of preparations for the historic launch that will send astronauts back to space from American soil for the first time since 2011.
Astronauts Doug Hurley and Bob Behnken are scheduled to launch at 4:33 p.m. EDT from Kennedy Space Center’s launch pad 39A, which was also used for the Apollo and space shuttle programs.
The astronauts are in the SpaceX Crew Dragon spacecraft that will carry them to the International Space Station.

“The hatch is closed. The crew is settled in. #LaunchAmerica is on,” tweeted NASA shortly before 3 p.m. EDT.
Earlier the astronauts said farewell to their families, Vice President Mike Pence, second lady Karen Pence, SpaceX CEO Elon Musk and NASA Administrator Jim Bridenstine.
President Donald Trump has also arrived at Kennedy Space Center to watch the launch.
The launch will be the first time a private company, rather than a national government, sends astronauts into orbit.
