Orbital Sciences Corporation

(Orbital)

Orbital Sciences was contracted under COTS in 2008.

Founded in 1982, Orbital is a world leader in space and launch systems. They are headquartered in Dulles, Virginia and have operations in Arizona, California, Maryland, and Virginia. Selected in 2006 for NASA's COTS (Commercial Orbital Transportation Services), Orbital is under contract to provide eight resupply missions to the ISS between 2012 and 2015.

Being developed for this service is an advanced maneuvering space vehicle called Cygnus™. The Cygnus is composed of a service module incorporating avionics, propulsion and power systems proven in Orbital's existing satellite products, and a pressurized cargo module based upon the previous Multi-Purpose Logistics Module originally developed by Thales Alenia Space for NASA. The first launch took place on 18 September 2013.

A related but separate development is the Antares™ launch vehicle. Antares is a two stage vehicle, expandable to three stages, capable of launching multiple payloads to low earth orbit. Initially, launches will take place from the Wallops Flight Facility, but Antares will also be qualified to launch from Vandenberg Air Force Base (California) or Cape Canaveral (Florida).
