Aircraft were sent to the debris area in the Atlantic Ocean and an investigation is ongoing.[11][12]It was the first Falcon 9 failure in the 19 launches of the rocket type.[13]According to the founder of SpaceX,Elon Musk, on Twitter: "[The] Falcon 9 [launch vehicle] experienced a problem shortly before first stage shutdown. Will provide more info as soon as we review the data." He added: "There was an overpressure event in the upper stage liquid oxygen tank. Data suggests counterintuitive cause."[14]Post-launch flight test[edit]Main article:SpaceX reusable launch system development programAfter theseparationof the second stage, SpaceX had planned to conduct aflight testandattempt to returnthe nearly-emptyfirst stageof the Falcon 9 through the atmosphere and land it on a 90-by-50-meter (300ft 160ft)floating platformcalled theautonomous spaceport drone ship.[15]This would have been SpaceX's third attempt to land the booster on a floating platform after earlier tests inJanuary 2015andApril 2015were not successful. The boosters were fitted with a variety of technologies to facilitate the flight test, includinggrid finsandlanding legsto facilitate the post-mission test.[15][16][17]
