It is used to launch small satellites for the US Government, and is a member of the Minotaur family of rockets produced by Orbital Sciences Corporation. Minotaur I rockets consist of the M55A1 first stage and SR19 second stage of a decommissioned Minuteman missile.〔 The Orion 50XL and Orion 38, from the Pegasus rocket, are used as third and fourth stages. A HAPS (Hydrazine Auxiliary Propulsion System) upper stage can also be flown if greater precision is needed, or the rocket needs to be able to manoeuvre to deploy multiple payloads.〔(【引用サイトリンク】url=http://www.orbital.com/NewsInfo/Publications/Minotaur_Guide.pdf )〕 It can place up to of payload into a low Earth orbit at 28.5 degrees of inclination.〔 〕 There have been eleven launches of the Minotaur I, all successful. Initially Minotaur I launches were conducted from Space Launch Complex 8 at the Vandenberg Air Force Base. Starting with the launch of TacSat-2 in December 2006, launches have also been conducted from Pad 0B at the Mid-Atlantic Regional Spaceport on Wallops Island.〔 ==Launch history== 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「Minotaur I」の詳細全文を読む スポンサード リンク
