The Demo-2 mission is the first launch with astronauts of the SpaceX Crew Dragon spacecraft and Falcon 9 rocket to the International Space Station as part of the agencys Commercial Crew Program. The test flight serves as an end-to-end demonstration of SpaceXs crew transportation system. Behnken and Hurley launched at 3:22 p.m. EDT on Saturday, May 30, from Launch Complex 39A at the Kennedy Space Center. A new era of human spaceflight is set to begin as American astronauts once again launch on an American rocket from American soil to low-Earth orbit for the first time since the conclusion of the Space Shuttle Program in 2011.

Officials said this will be the 7th mission for the X-37B.
“We benefit greatly from our partnerships with other government agencies and from commercially derived developments,” said Dr. Walt Lauderdale, Mission Director and lead for Falcon Systems and Operations at SSC. “When we look at the upswing in the launch tempo, adapting to change is our standard operating procedure that gives us the capacity and throughput we will need to support future national security space requirements.”
Its last record-setting mission lasted over 900 days.
