Intelsat Ltd. is a communications satellite services provider.

Originally formed as International Telecommunications Satellite Organization (INTELSAT), it was—from 1964 to 2001—an intergovernmental consortium owning and managing a constellation of communications satellites providing international broadcast services.

As of March 2011, Intelsat operates a fleet of 52 communications satellites, which is the world's largest fleet of commercial satellites.

The former PanAmSat Corporation founded in 1984 by Reynold (Rene) Anselmo, was a satellite service provider headquartered in Greenwich, Connecticut. It operated a fleet ofcommunications satellites used by the entertainment industry, news agencies, internet service providers, government agencies, and telecommunication companies. Anselmo got the idea for PanAmSat from Martine Rothblatt, an independent communications lawyer in Washington, D.C., to whom he had turned to for advice regarding difficulties he was encountering in getting reasonably priced satellite transmission of his UHF-TV based Spanish International Network (SIN), with studios on 42nd Street in New York City. Rothblatt had written a business plan entitled PanAmSat for her MBA thesis at UCLA's Graduate School of Management and was seeking a financial backer. Anselmo partnered with Rothblatt on the PanAmSat project, with Anselmo providing financing and Rothblatt filing for approval from the Federal Communications Commission and lining up an initial satellite from RCA Astro-Electronics and a heavily discounted launch from Arianespace.

PanAmSat effectively broke the monopoly on international satellite communications which was held by Intelsat, an international treaty-based organization founded and owned by several countries including the United States. PanAmSat, led by Anselmo, successfully lobbied the United States Congress to permit it to operate globally, competing against Intelsat. PanAmSat (and Anselmo) became famous for full-page advertisements in the Wall Street Journal depicting Spot, the PanAmSat mascot, urinating on politicians' legs. The company's motto was "Truth and Technology Will Triumph Over Bullshit and Bureaucracy."

Following the death of Rene Anselmo in 1995,^[1] his widow Mary Anselmo controlled the company for a time. PanAmSat was sold to Hughes Electronics, a division of General Motors, in a $3 billion cash and stock deal. The satellite operations continued to be under PanAmSat with Hughes being the majority shareholder. In May 1997, Hughes Communication Galaxy merged with PanAmSat, adding 9 more satellites to its fleet. In 2003, News Corporation purchased Hughes Electronic's PanAmSat division and on April 24, 2004 sold PanAmSat to a consortium ofprivate equity firms in an leveraged buyout including Kohlberg Kravis Roberts & Co. (KKR), Carlyle Group and Providence Equity Partners for $4.3 billion.

Stratolaunch Systems is a space transportation venture specializing in air launch to orbit, with its corporate headquarters located in Huntsville, Alabama, USA.

It was founded in 2011 by Microsoft co-founder Paul G. Allen and Scaled Composites founder Burt Rutan, who had previously collaborated on the creation of SpaceShipOne. The newly envisioned launch system will use similar components to that of Virgin Galactic though it will be made for orbital launch instead of sub-orbital.

The start up will build a mobile launch system with three primary components; a carrier aircraft to be build by Scaled Composites, A multi-stage launch vehicle built by Space Exploration Technologies (SpaceX), and a mating and integration system to be built by Dynetics.

Galileo is a joint initiative of the European Commission (EC) and the European Space Agency (ESA). Galileo will be Europe’s own global navigation satellite system, providing a highly accurate, guaranteed global positioning service under civilian control. It will be inter-operable with GPS and GLONASS, the two other GNSS (Global Navigation Satellite Systems). The complete system consists of:

• A space segment of 30 MEO satellites in 3 planes inclined at 56º

• A launch segment to place the satellites into their operational orbits

• A control ground segment for monitoring and control of the satellites

• A mission ground segment managing all mission specific data

• A user ground segment of equipment capable of receiving and using Galileo signals

The Galileo spacecraft was an unmanned spacecraft sent by NASA to study the planet Jupiter and its moons. Named after the astronomer and Renaissance pioneer Galileo Galilei, it was launched on October 18, 1989 by the Space Shuttle Atlantis on the STS-34 mission. It arrived at Jupiter on December 7, 1995, a little more than six years later, via gravitational assist flybys of Venus and Earth.

Despite suffering from antenna problems, Galileo conducted the first asteroid flyby near 951 Gaspra, discovered the first asteroid moon, Dactyl, around the asteroid 243 Ida, and was the first spacecraft to orbit Jupiter. It furthermore launched the first probe into Jupiter's atmosphere.

The spacecraft measured the atmospheric composition of Jupiter and directly observed ammonia clouds, which seem to be created by an outflow from the lower depths of Jupiter's atmosphere. Galileo also registered Io's volcanism and the plasma interactions between its and Jupiter's atmospheres. Other studies gave support for the popular theory of liquid oceans under the icy surface of Europa. There were also indications of similar liquid-saltwater layers under the surfaces of Ganymede and Callisto, while Ganymede was shown to possess a magnetic field. New evidence was also found for the existence of exospheres around Europa, Ganymede, and Callisto.

It was furthermore discovered that Jupiter's faint ring system is formed by dust from impacts on the four small inner moons. The extent and structure of Jupiter's magnetosphere was also mapped.

Galileo also provided the only direct observation of Comet Shoemaker-Levy 9's impact into the atmosphere of Jupiter in 1994.

On September 21, 2003, after 14 years in space and 8 years of service in the Jovian system, Galileo's mission was terminated by sending the orbiter into Jupiter's atmosphere at a speed of nearly 50 kilometres per second to avoid any chance of it contaminating local moons with bacteria from Earth. Of particular concern was the ice-crusted moon Europa, which, thanks to Galileo, scientists now suspect harbors a potentially life-supporting saltwater ocean beneath its surface.

MetOp is a series of three polar orbiting meteorological satellites operated by EUMETSAT, the European Organisation for the Exploitation of Meteorological Satellites.

The satellites form the space segment component of the overall EUMETSAT Polar System (EPS), which in turn is the European half of the EUMETSAT/NOAA Initial Joint Polar System (IJPS). The satellites carry a payload comprising 11 scientific instruments and two which support Search and Rescue services. In order to provide data continuity between MetOp and NOAA Polar Operational Satellites (POES), several instruments are carried on both fleets of satellites.

(ex   Marconi Space and Defence Systems)

Marconi Electronic Systems (MES), or GEC-Marconi as it was until 1998, was the defence arm of The General Electric Company (GEC). It was demerged from GEC and acquired by British Aerospace (BAe) on November 30, 1999 to form BAE Systems. GEC then renamed itself Marconi plc.

MES exists today as BAE Systems Electronics Limited, a subsidiary of BAE Systems, but the assets were rearranged elsewhere within that company. MES-related businesses include BAE Systems Submarine Solutions, BAE Systems Surface Ships, BAE Systems Insyte and SELEX Galileo (now owned by Finmeccanica).
