2011 witnessed the final Space Shuttle mission to the International Space Station (ISS) and the subsequent retirement of the fleet. Two private companies – SpaceX and Orbital Sciences Corporation – were selected to provide cargo delivery services to the station until 2015, under the Commercial Orbital Transportation Services (COTS) program.
SpaceX developed the Falcon 9 – a medium-lift rocket with payload capacity of 10,450 kilograms (23,000 lb). Today, it became the first 100% commercially developed launcher to deliver a payload to the International Space Station.
NASA’s administrator Charles Bolden said: “Today marks the beginning of a new era in exploration… The significance of this day cannot be overstated; a private company has launched a spacecraft to the International Space Station that will attempt to dock there for the first time. And while there is a lot of work ahead to successfully complete this mission, we are certainly off to a good start.”
In 2013, SpaceX is planning to test a much larger rocket, with over twice the capacity of the Space Shuttle – the Falcon Heavy.
