Antares A-ONE mission was the first launch of Orbital
Science's' new Antares medium-class space launch vehicle. It was
launched on 21 April 2013 from the Mid-Atlantic Regional Spaceport
at NASA's Wallops Flight Facility.
Antares Rocket First Flight
The test flight was the first launch from the pad at Wallops and
was the first flight of Antares, which delivered the equivalent
mass of a spacecraft, a so-called mass simulated payload, into
The aim of the A-ONE mission was to demonstrate the operational Antares launch
system, from roll-out of the rocket from its integration facility, through
emplacement on the pad and fueling, to launch and delivery a simulated
payload to a target orbit of 250 km x 300 km with an inclination of 51.6
The launch was made from the Mid-Atlantic Regional Spaceport (MARS) at NASA's
Wallops Flight Facility. The A-ONE launch was broadcast on NASA TV.
The main payload was the Cygnus Mass Simulator (CMS). It had a a mass of 3,800
kg (8,400 pounds) with a height of 5,061 mm (199.25 inches) and a diameter of
2,900 mm (114 inches).
The secondary payloads were four CubeSats that were deployed from the CMS: Three
PhoneSats, built by NASA's Ames Research Center. Dove-1, built by Cosmogia Inc
carried a 'technology development Earth imagery experiment' using the Earth's
magnetic field for attitude control.

Launch Attempt on Wednesday 17 April.
Orbital scrubbed Wednesday's planned launch of its
Antares vehicle because of a premature separation of an umbilical
connection on the second stage. Next attempt was set for Friday 19
Launch Attempt on Friday 19 April.
Friday's attempt was scrubbed in anticipation of bad
weather. Another launch opportunity was available on Sunday.
Launch Attempt on Saturday 20 April.
Excessive wind levels caused mission managers to
delay Saturday's launch attempt of the Antares rocket. The high-altitude wind speeds exceeded range safety
restrictions. Launch was re-scheduled for Sunday 21 April at 5 pm
Antares Launches Successfully on Sunday 21 April.
Orbital Sciences launches its Antares rocket at
5:00 pm EDT from the new Mid-Atlantic Regional Spaceport Pad-0A
at the agency's Wallops Flight Facility in Virginia.
Following this launch, Orbital will carry out a full flight
demonstration of its new Antares/Cygnus cargo delivery system to
the International Space Station (ISS) around mid-year 2013.
