Antares A-ONE

Antares A-ONE was the maiden flight of Antares from MARS Pad 0A, launching on April 21st, 2013. The payload was a mass simulator of the Cygnus spacecraft that served to properly test the launch vehicle's ability to deliver Cygnus to the International Space Station. Antares A-ONE also delivered CubeSats that were deployed from the simulated Cygnus payload. This launch of the Antares 110 was succeeded by Orb-D1 five months later in September 2013.
