Antares A-ONE mission was the maiden flight of Orbital Sciences Corporation' Antares launch vehicle including the ascent to space and accurate delivery of a simulated payload, the Cygnus Mass Simulator (CMS), which was launched 21 April 2013.[1] It was launched from Pad 0A at the Mid-Atlantic Regional Spaceport (MARS), Wallops Flight Facility, Virginia.[1] The simulated payload simulates the mass of the Cygnus cargo spacecraft.[1] This dummy payload was sent into an orbit of Шаблон:Cvt with an orbital inclination of 51.6°, the same launch profile it will use for Orbital's upcoming cargo supply missions to the International Space Station (ISS) for NASA.[1]
This launch along with several other activities leading up to it, are paid milestones under NASA's Commercial Orbital Transportation Services (COTS) program.[2]
Primary payload
The primary payload was the Cygnus Mass Simulator. It had a height of Шаблон:Cvt, a diameter of Шаблон:Cvt and a mass of Шаблон:Cvt.[3] It was equipped with 22 accelerometers, 2 microphones, 12 digital thermometers, 24 thermocouples and 12 strain gages.[3]
Secondary payloads
Four Spaceflight Industries Inc. CubeSat nanosatellites were deployed from the dummy payload.[4]
The secondary payloads were four CubeSats that were deployed from the CMS.[3] Three of them were PhoneSats, 1U CubeSats built by NASA's Ames Research Center.[3] These were named Alexander, Graham and Bell, after the Alexander Graham Bell, inventor of the telephone.[3] The purpose of these three satellites was to demonstrate the use of smartphones as avionics in CubeSats.[3] They each had a mass of Шаблон:Cvt and were powered by lithium batteries.[3] The fourth nanosat was a 3U CubeSat, called Dove-1, built by Cosmogia Inc. It carried a "technology development Earth imagery experiment" using the Earth's magnetic field for attitude control.[3][5]
