Orbital: Серіктерді құрастыру және ұшыру компаниясының тарихы

American company which specializes in the manufacturing and launch of satellites

Orbital was headquartered in Dulles, Virginia and publicly traded on the New York Stock Exchange with the ticker symbol ORB. Orbital's primary products were satellites and launch vehicles, including low Earth orbit (LEO), geosynchronous Earth orbit and planetary spacecraft for communications, remote sensing, scientific and defense missions; ground and air launched launch vehicles that delivered satellites into orbit; missile defense systems that were 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 29 April 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 9 February 2015 and Orbital Sciences ceased to exist as an independent entity. On 18 September 2017, Northrop Grumman announced plans to purchase Orbital ATK for US$7.8 billion in cash plus assumption of US$1.4 billion in debt, and on 6 June 2018, the acquisition was completed, and Orbital ATK became Northrop Grumman Innovation Systems. As of 1 January 2020, the name was changed to Space Systems under a large restructuring and rebranding initiative.

Orbital was founded and incorporated in 1982 by three friends who had met earlier while at Harvard Business School — David W. Thompson, Bruce Walker Ferguson, and Scott L. Webster. Initial capitalization for Orbital was provided by Fred C. Alcorn, a Texas oilman and Sam Dunnam, a Texas businessman in September 1982. In 1985, Orbital procured its first contract for providing up to four transfer orbital stage (TOS) vehicles to NASA. In 1987, the seeds for the Orbcomm constellation were planted when Orbital began investigating a system using low Earth orbit (LEO) satellites to collect data from remote locations. In 1988, Orbital acquired Space Data Corporation in Arizona — one of the world's leading suppliers of suborbital rockets — thereby broadening its rocket business and manufacturing capabilities. This was followed by the opening of a new facility in Chandler, Arizona in 1989 to house the company's expanding rocket business. In 1990, the company successfully carried out eight space missions, highlighted by the initial launch of the Pegasus launch vehicle, the world's first privately developed space launch vehicle (the claim of being the first privately developed space launch vehicle can be contested as Pegasus received significant funding from NASA and DARPA, and a predecessor private rocket exists, the Conestoga rocket). Shortly following the successful Pegasus launch, Orbital conducted an initial public offering (IPO) in 1990 and began trading on the NASDAQ stock exchange. In 1993, Orbital established its headquarters in Dulles, Virginia. In 1994, Orbital successfully conducted the inaugural launch of the Taurus (now renamed as Minotaur C) launch vehicle. In the early 2000s, Orbital continued expanding its missile defense systems business with a US$900 million award to develop, build, test and support interceptor booster vehicles. In 2006, Orbital conducted its 500th mission since the company's founding with products that included satellites, launch vehicles, and missile defense systems. In 2007, the first interplanetary spacecraft built by Orbital, Dawn was launched on an eight year, three billion mile journey to the main asteroid belt between Mars and Jupiter. A major milestone in the company's history was in 2008 when it received a long term NASA contract to provide cargo transportation services to and from the International Space Station (ISS) with a value of approximately US$1.9 billion for missions from 2011 to 2015. Orbital used its Cygnus spacecraft and Antares launch vehicle to transport cargo to ISS following the success of Cygnus Orb D1 and Cygnus CRS Orb 1.

Orbital Science made a number of strategic acquisitions in the 1990s and 2000s to strengthen its position in the satellite market. In 1994, Orbital completed acquisition of Fairchild Industries' subsidiary Space and Defense Corporation, and merged the Fairchild Space business with its own satellite design and manufacturing division. In 1997, Orbital acquired CTA, Inc, a company that, under the spacecraft design engineering and business leadership of Tom van der Heyden designer of the GEOStar spacecraft had designed and built the first geostationary "lightsat" under contract to Indonesia for Asia's first Direct Broadcast Satellite (DBS) television broadcast program, and the world's first S Band television broadcast satellite providing an entry into the fast growing Geosynchronous (GEO) communications satellite market. In 2010, Orbital acquired the Gilbert, Arizona based satellite development and manufacturing unit from General Dynamics (General Dynamics Advanced Information Systems, formerly Spectrum Astro) to complement its main satellite manufacturing facility in Dulles, Virginia.

On 29 April 2014, Orbital Sciences announced that it had entered into a definitive agreement with Alliant Techsystems to combine Orbital and ATK's Aerospace and Defense (A&D) Groups to create a US$4.5 billion (combined calendar year 2013 annual revenue), 13000 person company. The new company was called Orbital ATK, Inc. The communications and imaging satellites developed by Orbital are smaller and more affordable. The geosynchronous orbit (GEO) communications satellites provide commercial satellite services such as
direct to home digital television, business data transmission, cable program distribution and wireless communications. In addition, Orbital also provides constellations of low Earth orbit communications satellites such as the 35 satellite ORBCOMM data communications network, and the 81 spacecraft (integration and test) for the IridiumNEXT constellation. Earth imagery and high resolution digital imaging satellites such as the OrbView series are also developed and manufactured by Orbital. The science and environmental satellites developed by Orbital perform scientific research, carry out deep space exploration (e. g. Dawn spacecraft), conduct remote sensing missions (e. g. Landsat 4, 5 and 8), and demonstrate new space technologies. In the last 10 years, Orbital has built more scientific and environmental monitoring satellites for NASA than any other company. The Minotaur ground launched launch vehicles combine Pegasus upper stages with either government supplied or commercially available first stage rocket motors to boost larger payloads to orbit. Minotaur IV combines decommissioned Peacekeeper rocket motors with proven Orbital avionics and fairings to provide increased lifting capacity for government sponsored payloads. In support of human space systems, Orbital is one of two companies providing commercial cargo resupply services to the ISS for NASA. Orbital's medium class rocket Antares is used to launch the Cygnus advanced maneuvering spacecraft to deliver cargo to the ISS. Under the Commercial Resupply Services (CRS) contract with NASA, Orbital will perform eight cargo missions to the ISS. Operational flights began in 2013 from the new Mid Atlantic Regional Spaceport (MARS) at Wallops Island in Virginia. In addition, the company is exploring opportunities to adapt the Cygnus design for other possible space exploration applications.

The TMS unit combined satellite navigation and wireless communications to enable transit control centers to manage the dispatch of public transit, highway service vehicles and commuter light rail systems. As of 2008, the technology was used by more than 60 clients, exceeding 27500 vehicles, or more than 30% of the United States and Canada fleet. TMS clients included some of the nation's largest fleet management systems, such as Los Angeles, Chicago, and Washington, D. C. In 2008, the technology services provider Affiliated Computer Services (ACS) Inc. agreed to buy the Transportation Management Systems unit for US$42.5 million. The sale transferred an estimated 130 to 140 Orbital employees based in Columbia, Maryland, to ACS.

Minotaur Employing a combination of U. S. government supplied rocket motors and Orbital's commercial launch technologies, the Minotaur family of launchers provides low cost access to space for government sponsored payloads. Minotaur I Minotaur I made its inaugural flight in January 2000, successfully delivering several small military and university satellites into orbit and marking the first ever use of residual U. S. Government Minuteman boosters in a space launch vehicle. To date, Minotaur I has conducted 11 missions with a 100% success record, having launched a total of 62 satellites. Minotaur IV The Minotaur IV space launch vehicle consists of three Peacekeeper solid rocket stages, a commercial Orion 38 fourth stage motor and subsystems derived from OSC's established space launch boosters, including a flight proven standard 92 inch fairing. Capable of boosting payloads more than 1,750 kg into orbit, Minotaur IV supports dedicated or shared launch missions and is compatible with multiple U. S. government and commercial launch sites. The inaugural Minotaur IV flight occurred in 2010 and five missions have been conducted through 2016 with a 100% success record boosting nine satellite into orbit and two hypersonic flight vehicles on suborbital trajectories. Minotaur V Minotaur V is a five stage evolutionary version of Minotaur IV to provide a cost effective capability to launch U. S. Government sponsored small spacecraft into high energy trajectories, including Geosynchronous Transfer Orbits (GTO) as well as translunar and beyond. Like Minotaur IV, the first three stages of the Minotaur V are former Peacekeeper solid rocket motors. The fourth and fifth stages are commercial STAR™ motors. The inaugural Minotaur V mission successfully boosted NASA's LADEE spacecraft on a lunar trajectory in September 2013. Minotaur VI The Minotaur VI vehicle adds a lower stage to the existing and flight demonstrated Minotaur IV vehicle configuration providing a significant increase in performance with only a modest increase in cost. Capable of boosting up to 2,600 kg to Low Earth Orbit, Minotaur VI is also available with an optional upper stage motor for high energy trajectory missions. Minotaur C The Minotaur C (formerly known as Taurus) space launch vehicle is a commercial variant of the Minotaur product line designed to serve the U. S. government market. Of 9 launches, 6 have been successful. Pegasus The three stage Pegasus is used to deploy small satellites weighing up to 1,000 pounds into low Earth orbit. Pegasus is carried aloft by the "Stargazer" L 1011 aircraft to approximately 40,000 feet over open ocean, where it is released and free falls five seconds before igniting its first stage rocket motor. With its unique delta shaped wing, Pegasus typically delivers satellites into orbit in a little over 10 minutes. Pegasus has conducted 42 missions since its inaugural launch in 1990, 37 of which were successful. Pegasus II Pegasus II was to be an air launched orbital rocket, which was under development in 2012–2015. The design was "shelved" by Stratolaunch in May 2015. Antares Antares is a two stage launch vehicle designed to deliver medium class payloads weighing up to 6120 kg into space. Antares utilizes refurbished Russian built engines which were originally manufactured in the 1960s and 1970s for the Soviet Moon rocket. Initially developed to demonstrate commercial re supply of the International Space Station under a NASA contract, the first launch took place on April 21, 2013, from Wallops Flight Facility, Virginia. The fifth launch ended in failure on October 28, 2014, completely destroying the vehicle and damaging the launch pad. Antares follow on Following the loss of the Antares rocket on the Orb 3 mission in October 2014, Orbital announced that it would not use "the 40 year old AJ 26 engines on the rocket’s next flight." The new first stage engine is reportedly the Russian RD 193 rather than the AJ 26 engines used in the initial version of the Antares launch vehicle, which were remanufactured Russian NK 33s. Orbital Sciences Corp. has reportedly signed a contract with Russia's NPO Energomash to supply 60 new built RD 181 engines for the Antares rocket. While Antares/AJ 26 is not flying and the follow on launch vehicle is in development and test, Orbital is shopping to purchase launch services for its Cygnus capsule to ISS cargo runs temporarily from another launch service provider. Cygnus is capable of delivering 2,000 kg of pressurized cargo to the ISS. An enhanced version to be flown in later CRS missions is able to deliver 2,700 kg of pressurized cargo. The first of the eight contracted Cygnus missions to the ISS was completed on 18 February 2014. The October 28, 2014, launch failure was the third contracted Cygnus mission to the ISS.

Orbital's Missile Defense Systems product line consists of interceptors and target vehicles. The Ground Based Interceptor Orbital is the sole supplier of interceptor boosters for the U. S. Missile Defense Agency's Ground Based Midcourse Defense (GMD) system, to defend against long range ballistic missile attacks. The GMD system is designed to intercept and destroy hostile ballistic missiles in their midcourse phase of flight before they reenter the Earth's atmosphere. Orbital is responsible for the design, development and testing of the Orbital Boost Vehicle (OBV), a silo launched, three stage rocket derived from its Pegasus, Taurus and Minotaur space launch boosters. The OBV has successfully conducted multiple test flights and has been deployed in silos in Alaska and California. Ballistic Missile Targets Orbital's family of target vehicles extends from long range ballistic target launch vehicles, which include targets for testing MDA's GMD system, to medium and short range target vehicles. Current programs include Air launched Intermediate Range Ballistic Missile (IRBM) targets and Ground launched Intercontinental Ballistic Missile(ICBM) targets. GQM 163A “Coyote” Anti Ship Cruise Missile Target The GQM 163A “Coyote” is used for Anti Ship Cruise Missile (ASCM) targets. It can achieve cruise speeds of over Mach 2.5 while flying approximately 15 feet above the ocean's surface ("sea skimming" trajectory). In addition to this sea skimming trajectory, Orbital has also successfully demonstrated a "high diver" trajectory mission.

Orbital's national security systems range from smaller, more affordable spacecraft buses (e. g. disaggregated systems) to hosted payload applications. Orbital advocates disaggregated systems because conceptually disaggregated systems can lower the cost and accelerate the development and deployment of national security space systems. For example, Orbital's GEOStar 1 spacecraft provides a compact platform optimized for GEO missions (adaptable for MEO for launch aboard Minotaur, Falcon, and EELV launch vehicles to deliver resilient capabilities in a relatively short period of time (years instead of decades).
