In 2005, SpaceX announced plans to pursue a human-rated commercial space program through the end of the decade.[20] The Dragon is a conventional blunt-cone ballistic capsule that is capable of carrying cargo or up to seven astronauts into orbit and beyond.[21] In 2006, NASA announced that the company was one of two selected to provide crew and cargo resupply demonstration contracts to the ISS under the COTS program.[22] SpaceX demonstrated cargo resupply and eventually crew transportation services using the Dragon.[4] The first flight of a Dragon structural test article took place in June 2010, from Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station (CCAFS) during the maiden flight of the Falcon 9 launch vehicle; the mock-up Dragon lacked avionics, heat shield, and other key elements normally required of a fully operational spacecraft but contained all the necessary characteristics to validate the flight performance of the launch vehicle.[23] An operational Dragon spacecraft was launched in December 2010 aboard COTS Demo Flight 1, the Falcon 9's second flight, and safely returned to Earth after two orbits, completing all its mission objectives.[24] In 2012, Dragon became the first commercial spacecraft to deliver cargo to the International Space Station,[5] and has since been conducting regular resupply services to the ISS.[25]
