'We are go' NASA astronauts Behnken, Hurley set to make history on SpaceX Crew Dragon
When Crew Dragon's hatch closes Wednesday afternoon, veteran NASA astronauts Bob Behnken and Doug Hurley will officially be strapped in for one of the most critical launches in recent memory.

With most major readiness reviews and pre-launch checks out of the way, the duo is set to launch from Kennedy Space Center's pad 39A on the first U.S.-hosted crewed mission in nearly a decade. NASA and SpaceX are targeting 4:33 p.m. ET for liftoff.
