How will astronauts embark on SpaceX Crew Dragon? They will use the Crew Access Arm, which provides a bridge to the spacecraft from the crew access tower located at Kennedy Space Launch Complex 39A. Center. The Dragon Crew is designed to allow astronauts to travel to the International Space Station with the company's Falcon 9 rocket as part of NASA's Crew Commercial program. The first unarmed flight of the Crew Dragon, known as the Demo-1, is scheduled for launch on March 2, 2019. This flight is an important step in bringing human launchings onto American rockets and space ships from US soil since 2011.
