This was the first such achievement by a rocket for orbital spaceflight.[10] In April 2016, with the launch of SpaceX CRS-8, SpaceX successfully vertically landed the first stage on an ocean drone ship landing platform.[11] In May 2016, in another first, SpaceX again landed the first stage, but during a significantly more energetic geostationary transfer orbit (GTO) mission.[12] In March 2017, SpaceX became the first to successfully re-launch and land the first stage of an orbital rocket.[13] In January 2020, with the third launch of the Starlink project, SpaceX became the largest commercial satellite constellation operator in the world.[14][15]
