About Antares

Designed to provide responsive and low-cost access to space, Antares is a two-stage vehicle (with optional third stage) that provides low-Earth orbit (LEO) launch capability for payloads weighing up to 8,000 kg. Internally funded by Northrop Grumman, Antares completed a risk reduction mission and a demonstration of commercial re-supply services for the International Space Station (ISS) under a NASA Commercial Orbital Transportation Services (COTS) agreement in 2013. Northrop Grumman commenced delivery of cargo to the ISS under the NASA Commercial Resupply Services (CRS) contract in 2014.

About Cygnus

Cargo is delivered to the station using Northrop Grumman's Cygnus spacecraft. The Cygnus spacecraft consists of two modules: the Service Module (SM) which incorporates the avionics, propulsion and power systems from Northrop Grumman's flight proven LEOStar and GEOStar spacecraft buses; and the Pressurized Cargo Module (PCM) which carries the crew supplies, spares and scientific experiments. The SM is integrated and tested at Northrop Grumman's Dulles, Virginia satellite manufacturing facility. The PCM is supplied by Thales Alenia Space and is produced in Turin Italy.
