Dragon CRS-8

SpaceX launches the unmanned Dragon CRS-8 (Commercial Resupply Mission 8) to the International Space Station, carrying supplies and experiments, as well as delivering via its cargo trunk the Bigelow Expandable Activity Module (BEAM), the first new addition to the ISS since 2011. The flight is a success, and for the first time, the Falcon 9 first stage returns intact to an unmanned drone barge in the Atlantic Ocean, where it can be refurbished and reused. Though SpaceX has previously brought an intact booster down on dry land, this is the first success in several attempts to recover the spent first stage at sea.
