Falcon 9 v1.1

Falcon 9 v1.1 was the second version of SpaceX's Falcon 9 orbital launch vehicle. It was developed over about two years, made its maiden launch in September 2013 with the CASSIOPE satellite, and flew its final mission in January 2016, replacing the retired Falcon 9 v1.0 after the second Commercial Resupply Services launch. The rocket was a significant evolution of the first version, with sixty percent more thrust and weight, upgraded Merlin 1D engines and a redesigned stage separation system. Both stages of the two-stage vehicle burned liquid oxygen and rocket-grade kerosene, and it could lift 13,150 kilograms to low Earth orbit or 4,850 kilograms to geostationary transfer orbit. From April 2014 it carried Dragon capsules to the International Space Station. The version also pioneered the reusability work of boostback, re-entry and controlled descent that its successor, Falcon 9 Full Thrust, completed with a propulsive landing.
