Falcon 9 Flight 10 is a Falcon 9 space launch that occurred on July 14, 2014. It was the fifth launch of the Falcon 9 v1.1 launch vehicle and carried six Orbcomm OG2 telecommunication satellites. All six satellites were successfully deployed.〔(【引用サイトリンク】title=OG2 Launch )〕 Following the first stage loft of the second stage and payload on its orbital trajectory, SpaceX conducted a successful flight test on the spent first stage that received considerable news attention. In the event, the first stage successfully decelerated from hypersonic velocity in the upper atmosphere, made a successful reentry, landing burn, and deployment of its landing legs and touched down on the ocean surface. The first stage was not recovered however as the hull integrity was breached on landing or on the subsequent "tip over and body slam". ==History== This launch schedule was particularly problematic and was delayed several times, with success on the fourth scheduled launch attempt on July 14, 2014.〔〔 Earlier launch attempts were: *delayed by SpaceX due to a first stage helium leak *delayed by Orbcomm due to a potential defect in one of their satellites.〔(【引用サイトリンク】title=Delayed SpaceX Falcon 9 rocket fires up its engines )〕 On June 20 a launch attempt was scrubbed due to a fluctuation in pressure readings on the second stage. *delayed one day by weather on June 21 when the launch window was closed due to poor weather conditions on the flight trajectory through the lower atmosphere *the June 22 attempt was scrubbed by SpaceX to address a potential concern with the launch vehicle identified during pre-flight checks.〔(【引用サイトリンク】title=Launch update )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Falcon 9 Flight 10」の詳細全文を読む スポンサード リンク
