Trailblazer was a technology demonstration satellite, which was to have been operated by the United States Air Force and the Missile Defense Agency. It was selected for launch under a "Jumpstart" contract, to demonstrate responsiveness, with the final payload being chosen less than a month ahead of the scheduled launch date, and was launched as the primary payload of the third Falcon 1, which failed just over two minutes after launch on 3 August 2008. Two previous Falcon 1 launches also failed to reach orbit, but the fourth succeeded although it only carried a dummy payload. It was originally built for a cancelled MDA project, and was based on a SpaceDev MMB-100 satellite bus. It was launched from Omelek Island, at 03:34 GMT. Several other payloads were to be launched aboard the same rocket, including two CubeSats for NASA, and a space burial payload for Celestis, which would have remained attached to the rocket in low Earth orbit. ==References== *(Gunter's Space Page - Trailblazer ) *(SpaceX Falcon Rocket: Third Flight the Charm? ) *(Trailblazer ) 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「Trailblazer (satellite)」の詳細全文を読む スポンサード リンク
