Antares launch vehicle placed into orbit Cygnus cargo spacecraft that shall deliver to ISS 1657 kg payload including the equipment necessary for operation at the station. Nanosatellites for the Earth surface imaging are also among the spacecraft cargoes. They will be delivered to designed orbits in the future by a method of ejection from the station through a special bay.
