NASA astronauts Robert Behnken and Douglas Hurley have completed a countdown dress rehearsal of the launch day events. The two are set to launch aboard a SpaceX Crew Dragon spacecraft on the company’s Falcon 9 rocket and fly to the International Space Station, marking the first crewed mission for the agency’s Commercial Crew Program. Read more for two videos and additional information.



The two started their day in the Astronaut Crew Quarters inside Kennedy’s Neil A. Armstrong Operations and Checkout Building before putting on their black-and-white SpaceX spacesuits. Then they took the elevator down to the ground level and exited through a pair of double doors, where a Tesla Model X waited. After the 20-minute ride to Launch Complex 39A, they entered Crew Dragon through the pad’s Crew Access Arm and checked their communications systems before the hatch was closed.
