Orbital Sciences Corporation

Orbital Sciences Corporation, commonly known as Orbital, was an American aerospace and defense company founded in 1982 by David W. Thompson, Bruce Walker Ferguson, and Scott L. Webster. The company developed a business around relatively small and medium-sized space systems for commercial operators, civil agencies, the U.S. military, and other government customers. Its portfolio covered spacecraft, launch vehicles, missile-defense targets and interceptors, human-rated cargo systems, satellite subsystems, and technical services. Orbital began by pursuing commercial and government opportunities in space transportation. One of its early breakthroughs was a 1985 NASA contract for Transfer Orbit Stage vehicles. The company expanded its rocket capabilities in 1988 by acquiring Space Data Corporation, a major supplier of suborbital rockets, and opened a production and engineering facility in Chandler, Arizona, the following year. In 1990, Orbital launched Pegasus, an air-launched rocket carried beneath the company's modified L-1011 aircraft, Stargazer. Pegasus established Orbital as a significant provider of launch services for small payloads and was followed by the company's initial public offering in the same year. The company broadened its satellite activities through acquisitions and internal development. Its spacecraft business supplied low-Earth-orbit communications satellites, geostationary communications platforms, Earth-imaging spacecraft, scientific and environmental satellites, and spacecraft buses. Orbital participated in the development of the ORBCOMM low-Earth-orbit data-communications network and built spacecraft for government, commercial, and scientific missions. The company also entered the geostationary communications market through its 1997 acquisition of CTA, Inc., and strengthened its satellite-manufacturing position in 2010 by acquiring General Dynamics' Gilbert, Arizona satellite-development and manufacturing unit. Orbital's launch portfolio eventually included Pegasus, Taurus, and the Minotaur family. Taurus, later renamed Minotaur-C, provided a larger ground-launched option for commercial and government payloads. Minotaur vehicles combined Orbital launch technology with government-supplied solid rocket motors, including motors derived from decommissioned Minuteman and Peacekeeper missile systems. In parallel, Orbital became an important supplier of suborbital target and interceptor vehicles used in U.S. missile-defense testing. The company also developed major scientific and human-spaceflight systems. Its Dawn spacecraft, launched in 2007, became the first spacecraft to orbit two extraterrestrial bodies during its mission to study Vesta and Ceres. In 2008, NASA selected Orbital for a Commercial Resupply Services contract to deliver cargo to the International Space Station. Orbital developed the Antares medium-class launch vehicle and Cygnus cargo spacecraft for that program; operational cargo flights began in 2013. Orbital provided engineering and technical personnel for space, science, and defense programs through its Technical Services Division. It also operated a Transportation Management Systems unit that combined satellite navigation and wireless communications for public-transit and service-vehicle fleet management. That unit was sold to Affiliated Computer Services in 2008. Orbital announced an agreement to combine with Alliant Techsystems in April 2014. The transaction closed on February 9, 2015, creating Orbital ATK and ending Orbital Sciences Corporation as an independent company. Northrop Grumman agreed to acquire Orbital ATK in 2017 and completed the transaction in June 2018. The former Orbital businesses subsequently became part of Northrop Grumman's space organization, later reorganized as Space Systems.

Orbital Sciences Corporation was incorporated in 1982 by David W. Thompson, Bruce Walker Ferguson, and Scott L. Webster, three former Harvard Business School classmates. Initial financing came from Texas businessmen Fred C. Alcorn and Sam Dunnam. The company initially concentrated on space transportation and related systems, securing a NASA contract in 1985 for Transfer Orbit Stage vehicles. Orbital began building a broader launch and spacecraft business during the late 1980s. In 1987 it investigated a low-Earth-orbit satellite system for collecting data from remote locations, an effort that contributed to the later ORBCOMM network. Its 1988 acquisition of Space Data Corporation added suborbital-rocket expertise and production capacity, while a new Chandler, Arizona facility supported the expanding launch-vehicle operation. The 1990 Pegasus launch was a defining moment. Pegasus used a carrier aircraft to release a rocket at altitude, giving small payload customers an alternative to conventional ground launches. Orbital carried out its initial public offering that year and began trading publicly. The company followed with the Taurus launch vehicle in 1994 and expanded its satellite business through acquisitions. It acquired Fairchild Industries' Space and Defense Corporation in 1994 and CTA, Inc. in 1997, gaining additional spacecraft engineering and geostationary communications capabilities. Orbital later sold the acquired electronics business in 2000. During the 2000s, Orbital developed into a diversified space and defense contractor. Its Space Systems Group built communications, imaging, scientific, environmental, and defense spacecraft. Its Launch Systems Group supplied Pegasus, Taurus, and Minotaur rockets and became a significant contractor for missile-defense target and interceptor launches. The company also delivered technical personnel and engineering services to government laboratories and space programs. In 2006 it marked its 500th mission since formation. Orbital's scientific work included the Dawn spacecraft, launched in 2007 to investigate Vesta and Ceres. Its human-spaceflight activities expanded substantially after NASA selected it in 2008 for Commercial Resupply Services. Orbital developed Antares and Cygnus to transport cargo to the International Space Station, with operational flights beginning in 2013. The company also pursued advanced national-security and flight-system programs, including work associated with an air-launched rocket concept for Stratolaunch Systems. Orbital maintained a range of facilities, including its headquarters and satellite-manufacturing operation in Dulles, Virginia; launch and spacecraft-processing activities at Wallops Island, Virginia; launch-vehicle operations in Chandler, Arizona; satellite manufacturing in Gilbert, Arizona; and engineering and defense activities at sites in Maryland, California, and Alabama. In April 2014, Orbital announced a definitive agreement to combine with Alliant Techsystems. The transaction closed on February 9, 2015, creating Orbital ATK, Inc. and ending Orbital Sciences Corporation as a standalone public company. Northrop Grumman announced its agreement to acquire Orbital ATK in September 2017. Following shareholder and regulatory approvals, the acquisition closed on June 6, 2018. The acquired business was initially organized as Northrop Grumman Innovation Systems and was later incorporated into Northrop Grumman's Space Systems organization.
