On June 23, 2017, SpaceX’s Falcon 9 rocket successfully launched the BulgariaSat-1 satellite into orbit—the first geostationary communications satellite in Bulgaria’s history. This mission marked the second reflight of a Falcon 9 first stage, having previously supported the Iridium-1 mission from Vandenberg Air Force Base in January of this year.
Following stage separation, the first stage of Falcon 9 successfully landed on SpaceX’s East Coast droneship “Of Course I Still Love You,” stationed in the Atlantic Ocean. This marks the first time a Falcon 9 first stage has landed on both SpaceX’s East and West coast droneships, having previously landed on “Just Read the Instructions” in the Pacific Ocean.
