After some earlier attempts that were basically very successful, this time, SpaceX actually did it perfectly!
They lauched their Falon 9 rocket, split off cargo into space, and landed the Falcon rocket back on earth on a drone ship. Friday, May 6, 2016, the rocket was launched from Cape Canaveral, Florida, USA. The rocket was carrying a 4700kg communication JCSAT-14 satellite. After splitting the first stage of the Falcon, the second stage took the satellite to 35,786 kilometers and the first stage landed back on our blue planet. Cudos to Elon!
