Orbital Sciences insignia

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.[6] It was launched from Pad 0A at the Mid-Atlantic Regional Spaceport (MARS), Wallops Flight Facility, Virginia.[6] The simulated payload simulates the mass of the Cygnus cargo spacecraft.[6] This dummy payload was sent into an orbit of 223 km × 237 km (139 mi × 147 mi) with an orbital inclination of 51.63°, the same launch profile it will use for Orbital's Cygnus cargo supply missions to the International Space Station (ISS) for NASA.

This launch along with several other activities leading up to it, are paid milestones under NASA's Commercial Orbital Transportation Services (COTS) program.[7]

Primary payload

[edit]

The primary payload was the Cygnus Mass Simulator. It had a height of 5.061 m (16.60 ft), a diameter of 2.896 m (9 ft 6.0 in) and a mass of 3,800 kg (8,400 lb).[8] It was equipped with 22 accelerometers, 2 microphones, 12 digital thermometers, 24 thermocouples and 12 strain gages.[8]

Secondary payloads

[edit]

Four Spaceflight Industries Inc. CubeSat nanosatellites were deployed from the dummy payload.[9]

The secondary payloads were four CubeSats that were deployed from the CMS.[8] Three of them were PhoneSats, 1U CubeSats built by NASA's Ames Research Center.[8] These were named Alexander, Graham and Bell, after the Alexander Graham Bell, inventor of the telephone.[8] The purpose of these three satellites was to demonstrate the use of smartphones as avionics in CubeSats.[8] They each had a mass of 1,124 kg (2,478 lb) and were powered by lithium batteries.[8] 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.[8][10]

Mission timeline

[edit]
  • Lift off of the Antares launch vehicle occurs two seconds after the first stage engines are ignited
  • The first stage engines shut off 228 seconds after lift-off
  • At 233 seconds, the first stage separates from the second
  • At 317 seconds, the payload fairing is jettisoned
  • At 326 seconds, the second stage's engine is ignited
  • At 481 seconds, the second stage is shut off
  • At 601 seconds, the Cygnus Mass Simulator separates [6]
