The Antares A-ONE is the maiden flight of Orbital Sciences' Antares rocket with a boilerplate payload, the Cygnus Mass Simulator, which was launched April 21, 2013.〔(Orbital Successfully Launches First Antares Rocket ), Orbital Sciences Press release, April 21, 2013〕 It was launched from Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, Virginia, USA.〔 The boilerplate payload simulates the mass of the Cygnus cargo spacecraft.〔 This dummy payload was sent into an orbit of "approximately 150 by 160 miles" (240 km x 260 km) with an inclination of 51.6 degrees.〔 Four Spaceflight Inc. CubeSat nanosatellites were deployed from the dummy payload. This launch along with several other activities leading up to it, are paid milestones under NASA's Commercial Orbital Transportation Services program. ==Payloads== The primary payload is the Cygnus Mass Simulator (CMS), it has a height of , a diameter of and a mass of . It is equipped with 22 accelerometers, 2 microphones, 12 digital thermometers, 24 thermocouples and 12 strain gages.〔 The secondary payloads are four CubeSats that were deployed from the CMS.〔 Three of them are PhoneSats, 1U CubeSats built by NASA's Ames Research Center.〔 These are named Alexander, Graham and Bell, after the inventor of the telephone.〔 The purpose of these three satellites is to demonstrate the use of smart phones as avionics in Cube Sats.〔 They each have a mass of and are powered by lithium batteries.〔 The fourth nanosat is a 3U CubeSat, called Dove-1, built by Cosmogia Inc. It carries a "technology development Earth imagery experiment" using the Earth's magnetic field for attitude control.〔 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「Antares A-ONE」の詳細全文を読む スポンサード リンク
