Orbital Sciences Corporation

Orbital Sciences Corporation (commonly referred to as Orbital) was an American company specializing in the design, manufacture and launch of small- and medium- class space and rocket systems for commercial, military and other government customers. It was headquartered in Dulles, Virginia and publicly traded on the New York Stock Exchange with the ticker symbol ORB. Orbital’s primary products are satellites and launch vehicles, including low-Earth orbit, geosynchronous-Earth orbit and planetary spacecraft for communications, remote sensing, scientific and defense missions; ground- and air-launched rockets that deliver satellites into orbit; missile defense systems that are used as interceptor and target vehicles; and human-rated space systems for Earth-orbit, lunar and other missions. Orbital also provided satellite subsystems and space-related technical services to government agencies and laboratories.

On April 29, 2014, Orbital Sciences announced that it would merge with Alliant Techsystems to create a new company called Orbital ATK, Inc. The merger was completed on February 9, 2015 and Orbital Sciences ceased to exist as an independent entity.

Orbital ATK

Orbital ATK Inc. is an American aerospace manufacturer and defense industry company. It was formed in 2015 from the merger of Orbital Sciences Corporation and parts of Alliant Techsystems.

Orbital ATK has a contract to develop the four-segment Space Shuttle Solid Rocket Booster into the five-segment boosters for the Space Launch System.

History

A merger of Orbital Sciences Corporation and the defense and aerospace divisions of Alliant Techsystems (ATK) was announced on April 29, 2014. The two companies had collaborated on several previous projects, including the use of 400 ATK rocket motors in Orbital's launch vehicles. The deal officially closed on February 9, 2015. ATK's sporting-goods division spun off to form Vista Outdoor on the same day.

Organization

Flight Systems Group

Based in Chandler, Arizona, the Flight Systems Group includes the Pegasus, Minotaur, and Antares launch vehicles as well as solid-propulsion and aerostructures programs.

Defense Systems Group

The Defense Systems Group, based in the Baltimore, Maryland area, produces tactical missiles, defense electronics, and medium- and large-caliber ammunition. The division also produces fuzing and warheads for both tactical missiles and munitions; precision metal and composite structures for medium and large-caliber ammunition, military aircraft, ground vehicles, and missile systems; load, assembly, and pack (LAP) of medium caliber munitions; and propellants and powders for the canister and commercial markets.

Antares (rocket)

Antares (/ænˈtɑːriːz/), known during early development as Taurus II, is an expendable launch system developed by Orbital Sciences Corporation (now Orbital ATK) to launch the Cygnus spacecraft to the International Space Station as part of NASA's COTS and CRS programs. Able to launch payloads heavier than 5,000 kg (11,000 lb) into low-Earth orbit, Antares is the largest rocket operated by Orbital ATK. Antares launches from the Mid-Atlantic Regional Spaceport and made its inaugural flight on April 21, 2013.

NASA awarded Orbital a Commercial Orbital Transportation Services (COTS) Space Act Agreement (SAA) in 2008 to demonstrate delivery of cargo to the International Space Station. For these COTS missions Orbital intends to use Antares to launch its Cygnus spacecraft. In addition, Antares will compete for small-to-medium missions. Originally designated the Taurus II, Orbital Sciences renamed the vehicle Antares, after the star of the same name, on December 12, 2011.

The first four Antares launch attempts were successful. During the fifth launch on October 28, 2014, the rocket failed catastrophically, and the vehicle and payload were destroyed.

Corporation

A corporation is a company or group of people authorized to act as a single entity (legally a person) and recognized as such in law. Early incorporated entities were established by charter (i.e. by an ad hoc act granted by a monarch or passed by a parliament or legislature). Most jurisdictions now allow the creation of new corporations through registration.

Corporations come in many different types but are usually divided by the law of the jurisdiction where they are chartered into two kinds: by whether or not they can issue stock, or by whether or not they are for profit.

Where local law distinguishes corporations by ability to issue stock, corporations allowed to do so are referred to as "stock corporations", ownership of the corporation is through stock, and owners of stock are referred to as "stockholders." Corporations not allowed to issue stock are referred to as "non-stock" corporations, those who are considered the owners of the corporation are those who have obtained membership in the corporation, and are referred to as a "member" of the corporation.
