The Earth Observing System (EOS) is a program of NASA comprising a series of artificial satellite missions and scientific instruments in Earth orbit designed for long-term global observations of the land surface, biosphere, atmosphere, and oceans. Since the early 1970s, NASA has been developing its Earth Observing System, launching a series of Landsat satellites in the decade. Some of the first included passive microwave imaging in 1972 through the Nimbus 5 satellite. Following the launch of various satellite missions, the conception of the program began in the late 1980s and expanded rapidly through the 1990s. Since the inception of the program, it has continued to develop, including; land, sea, radiation and atmosphere. Collected in a system known as EOSDIS, NASA uses this data in order to study the progression and changes in the biosphere of Earth. The main focus of this data collection surrounds climatic science. The program is the centrepiece of NASA's Earth Science Enterprise.
Orbital Sciences Corporation 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 became a subsidiary of Northrop Grumman, known as Northrop Grumman Space Systems.
The design of spacecraft covers a broad area, including the design of both robotic spacecraft, and spacecraft for human spaceflight.
MidSTAR-1 is an artificial satellite produced by the United States Naval Academy Small Satellite Program. It was sponsored by the United States Department of Defense (DoD) Space Test Program (STP), and was launched on March 9, 2007 at 03:10 UTC, aboard an Atlas V expendable launch vehicle from Cape Canaveral Air Force Station. MidSTAR-1 flew along with FalconSat 3, STPSat 1, and CFESat as secondary payloads; the primary payload was Orbital Express.
IndoStar-1, also known as Cakrawarta-1, was a communication satellite that was launched the evening of November 12, 1997 at 21:48 GMT aboard an Ariane 44L-3 rocket from Kourou, French Guiana. As the first direct broadcasting satellite (DBS) in Asia, IndoStar-1 would initiate a new communication service for Indonesian society such as direct-to-home television.
The A2100 is a model of communications satellite spacecraft made by Lockheed Martin Space Systems. It is used as the foundation for telecommunications payloads in geosynchronous orbit, as well as GOES-R weather satellites and GPS Block IIIA satellites. Over 40 satellites use the A2100 bus.
The STAR-2 Bus is a fully redundant, flight-proven, spacecraft bus designed for geosynchronous missions.
Horizons-2 is a Ku band communications satellite owned by Horizons Satellite, a joint venture between SKY Perfect JSAT Group and Intelsat. Its orbital slot is located at 74° west longitude.
TacSat-4 is the third in a series of U.S. military experimental technology and communication satellites. The United States Naval Research Laboratory (NRL) is the program manager. The Office of Naval Research (ONR) sponsored the development of the payload and funded the first year of operations. The Office of the Director of Defense Research and Engineering (DDR&E) funded the standardized spacecraft bus and the Operationally Responsive Space Office (ORS) funded the launch that will be performed by the Air Force's Space and Missile Systems Center (SMC).
A space tug is a type of spacecraft used to transfer spaceborne cargo from one orbit to another orbit with different energy characteristics. The term can include expendable upper stages or spacecraft that are not necessarily a part of their launch vehicle. However, it can also refer to a spacecraft that transports payload already in space to another location in outer space, such as in the Space Transportation System concept. An example would be moving a spacecraft from a low Earth orbit (LEO) to a higher-energy orbit like a geostationary transfer orbit, a lunar transfer, or an escape trajectory.
The EELV Secondary Payload Adapter (ESPA) is an adapter for launching secondary payloads on orbital launch vehicles.
Electra, formally called the Electra Proximity Link Payload, is a telecommunications package that acts as a communications relay and navigation aid for Mars spacecraft and rovers. The use of such a relay increases the amount of data that can be returned by two to three orders of magnitude.
Northrop Grumman Innovation Systems (NGIS) was a sector of Northrop Grumman from 2018 through 2019. It was formed from Orbital ATK Inc. a company which resulted from the merger of Orbital Sciences Corporation and parts of Alliant Techsystems in 2015. Orbital ATK was purchased by Northrop Grumman in 2018. Northrop Grumman Innovation Systems designed, built, and delivered space, defense, and aviation-related systems to customers around the world both as a prime contractor and as a merchant supplier. It had a workforce of approximately 12,000 employees dedicated to aerospace and defense including about 4,000 engineers and scientists; 7,000 manufacturing and operations specialists; and 1,000 management and administration personnel. With Northrop Grumman's reorganization of its divisions effective January 1, 2020, NGIS was split, with most of the sector merging with other Northrop Grumman businesses into a new Space Systems sector.
NG-10, previously known as OA-10E, is the eleventh flight of the Northrop Grumman uncrewed resupply spacecraft Cygnus and its tenth flight to the International Space Station under the Commercial Resupply Services (CRS-1) contract with NASA. The mission launched on 17 November 2018, at 09:01:31 UTC. This particular mission is part of an extension of the initial CRS contract that enables NASA to cover the ISS resupply needs until the Commercial Resupply Services-2 (CRS-2) contract enters in effect.
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. The GEOStar-3 Bus can accommodate payloads of up to 800 kilograms and 8,000 watts.
N-STAR c, is a geostationary communications satellite originally ordered by NTT DoCoMo and later fully acquired by SKY Perfect JSAT Group. It was designed and manufactured by Lockheed Martin, which acted as prime, developed the payload and did the final integration and testing, and Orbital Sciences Corporation, which supplied the satellite bus on the GEOStar-2 platform and procured the launch services. It had a launch weight of approximately 1,645 kg (3,627 lb), and a 15-year design life. Its payload is composed of 1 C-band, and 20 S-band transponders and its stationed in the 136° East longitude.
The GEOStar is a family of satellite buses designed and manufactured by Northrop Grumman Innovation Systems. The family started focused on small geostationary communications satellites. The first iterations focused on the sub-5 kW commercial segment that was left vacated after the retirement of the HS-376 satellite bus. It started with the STARBus on CTA Space Systems, which was later bought successively by Orbital Sciences, Orbital ATK, and most recently Northrop Grumman Innovation Systems.
SOLRAD 4 was a solar X-rays, ultraviolet, and electronic surveillance satellite. Developed by the United States Navy's United States Naval Research Laboratory (USNRL), it was the fourth in both the SOLRAD and the GRAB programs.
