The Crew Dragon spacecraft will transport them to the International Space Station as part of NASA's Commercial Crew Program. Their upcoming flight test is known as Demo-2, short for Demonstration Mission 2. The Crew Dragon will launch on SpaceX's Falcon 9 rocket from Launch Complex 39A at NASA's Kennedy Space Center in Florida, USA. In March 2019, SpaceX completed an uncrewed flight test of Crew Dragon known as Demo-1, which was designed to validate end-to-end systems and capabilities, bringing NASA closer to certification of SpaceX systems to fly a crew.
