The Falcon rocket family is a set of launch vehicles developed by SpaceX. They are the first orbital launch vehicles to be entirely designed in the 21st century. The vehicles in this family include the flight-tested Falcon 1 and Falcon 9. The Falcon 1 made its first successful flight on 28 September 2008, after several failures on the initial attempts. The larger Evolved Expendable Launch Vehicle -class Falcon 9 flew successfully into orbit on its maiden launch on 4 June 2010. The Falcon 9 is eventually intended to be a reusable vehicle. SpaceX is currently in production of the first Falcon Heavy launch system. Other designs for boosters with even larger payload lifting capabilities are currently being researched, but not yet confirmed.
