GEOStar-3
The GEOStar-3 is a communications satellite spacecraft model made by Northrop Grumman Innovation Systems. GEOStar-3 represents an evolutionary growth from Northrop Grumman Innovation Systems GEOStar-2 platform. GEOStar-3 Bus can accommodate payloads of up to 800 kilograms and 8,000 watts. Some changes to the GEOStar-3 bus provides increased battery capacity and solar array power, enabling it to provide up to eight kilowatts of power to the payload. The bus can be customized, including compatibility with all commercially available launch vehicles and the option to launch with another spacecraft on certain launch vehicles. In addition to increased payload power, GEOStar-3 also has the option of utilizing electric propulsion, which allows it to complete its fifteen to seventeen year mission life with less fuel.

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 launch vehicle systems for commercial, military and other government customers. In 2014, Orbital merged with Alliant Techsystems to create a new company called Orbital ATK, Inc., which in turn was purchased by Northrop Grumman in 2018. The remnants of the former Orbital Sciences Corporation today are a subsidiary of Northrop Grumman, known as Northrop Grumman Innovation Systems. 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 d ...

Spacecraft Bus
A satellite bus (or spacecraft bus) is the main body and structural component of a satellite or spacecraft, in which the payload and all scientific instruments are held. Bus-derived satellites are opposed to specially produced satellites. Bus-derived satellites are usually customized to customer requirements, for example with specialized sensors or transponders, in order to achieve a specific mission. They are commonly used for geosynchronous satellites, particularly communications satellites, but are also used in spacecraft which occupy lower orbits, occasionally including low Earth orbit missions. Examples Some satellite bus examples include: * Boeing DS&S 702 * Lockheed Martin Space Systems A2100 * Alphabus * INVAP ARSAT-3K * Airbus D&S Eurostar * ISRO's I-1K, I-2K, I-3K, I-4K, I-6K, and Indian Mini Satellite bus * NASA Ames MCSB * SSL 1300 * Orbital ATK GEOStar * Mitsubishi Electric DS2000 * Spacecraft bus of the James Webb Space Telescope * SPUTNIX TabletSat * S ...

HYLAS-4 is a telecommunications satellite owned and operated by Avanti Communications and manufactured by Orbital ATK (now Northrop Grumman Innovation Systems) that was launched by an Ariane 5 rocket on 5 April 2018. Mission The satellite is built to provide high speed data transmission services to Africa, Latin America and Europe. It is based on Orbital ATK's Star-3 Bus, delivering 64 28 GHz fixed beams covering Africa and parts of Europe. There are also four independent steerable beams that can serve Africa, South America and Europe. The capacity will partially be used to allow Avanti to expand into new markets and provide growth for existing markets. Launch The satellite was launched into geosynchronous orbit by Arianespace on an Ariane 5 rocket in its ECA variant from ELA-3 at Guiana Space Centre in French Guiana French Guiana ( or ; french: link=no, Guyane ; gcr, label= French Guianese Creole, Lagwiyann ) is an overseas department/region and single territorial col ...

Satellite Buses
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsion, ...

DARPA
The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military. Originally known as the Advanced Research Projects Agency (ARPA), the agency was created on February 7, 1958, by President Dwight D. Eisenhower in response to the Soviet Union, Soviet launching of Sputnik 1 in 1957. By collaborating with academia, industry, and government partners, DARPA formulates and executes research and development projects to expand the frontiers of technology and science, often beyond immediate U.S. military requirements.Dwight D. Eisenhower and Science & Technology, (2008). Dwight D. Eisenhower Memorial CommissionSource ''The Economist'' has called DARPA the agency "that shaped the modern world," and pointed out that "Moderna COVID-19 vaccine, Moderna's COVID-19 vaccine sits alongside weather satellites, Global Positioning System, GPS, Unmann ...

Mission Extension Vehicle
A Mission Extension Vehicle (MEV) is a type of spacecraft designed to extend the functional lifetime of another spacecraft through on-orbit satellite servicing. They are 2010s-design small-scale in-space satellite-refueling spacecraft first launched in 2019. The MEV spacecraft grew out of a concept proposed in 2011 by ViviSat, a 50/50 joint venture of aerospace firms US Space and Alliant Techsystems (ATK). The joint venture was created in 2010 for the purpose of designing, producing and operating the MEV program. Since the original conception of the MEV program by the ViviSat company, the Vivisat venture was shut down for a time, and the company was dissolved by Orbital ATK in April 2016. The MEV program continued on as a solo-project of Orbital ATK, which was subsequently purchased by Northrop Grumman in 2018. The MEV program continued under Northrop Grumman and in 2019, launched ''MEV-1'' to dock and reposition Intelsat 901, an objective reached in April 2020. Servicing an o ...
