How will astronauts board the SpaceX Crew Dragon? They'll use the Crew Access Arm, which provides a bridge to the spacecraft from the crew access tower at Kennedy Space Center's Launch Complex 39A. The Crew Dragon is designed to fly astronauts to the International Space Station on the company’s Falcon 9 rocket as part of NASA’s Commercial Crew Program. The first uncrewed flight of the Crew Dragon, known as Demo-1, is scheduled to launch March 2, 2019. The uncrewed flight is an important step in returning human launches on American rockets and spacecraft to the space station from U.S. soil since 2011.
