Public Company
A public company is a company whose ownership is organized via shares of share capital, stock which are intended to be freely traded on a stock exchange or in over-the-counter (finance), over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listing (finance), listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states and so have associations and formal designations, which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation, though a corporation need not be a public company. In the United Kin ...

Satellite
A satellite or an artificial satellite is an object, typically a spacecraft, placed into orbit around a celestial body. They have a variety of uses, including communication relay, weather forecasting, navigation ( GPS), broadcasting, scientific research, and Earth observation. Additional military uses are reconnaissance, early warning, signals intelligence and, potentially, weapon delivery. Other satellites include the final rocket stages that place satellites in orbit and formerly useful satellites that later become defunct. 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 are small CubeSats. Similar satellites can work together as groups, forming constellatio ...

Stargazer (aircraft)
''Stargazer'' is a Lockheed L-1011 TriStar built in 1974, that was modified in 1994 for use by Orbital Sciences (now part of Northrop Grumman) as a mother ship for the Pegasus, a small-lift launch vehicle. , 45 rockets (containing nearly 100 satellites) have been launched from ''Stargazer''. ''Stargazer'' is the only L-1011 airframe still airworthy. History The first Pegasus launch to use Stargazer was conducted on June 27, 1994, as the maiden flight of the Pegasus-XL. Previous launches used the NASA-operated Boeing B-52 nicknamed "Balls 8," which was also used for four subsequent launches, as the original Pegasus could not be launched from Stargazer due to clearance issues. A modified version, the Pegasus-H, was introduced to rectify this. Stargazer was also used for captive tests and transportation of the X-34 hypersonic research aircraft; however, the drop tests used Balls 8. Pegasus launches using Stargazer are usually conducted from Vandenberg Air Force Base. Launches ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antares (rocket)
Antares (), known during early development as Taurus II, is an American expendable medium-lift launch vehicle developed and built by Orbital Sciences Corporation (later Orbital ATK and Northrop Grumman) with financial support from NASA under the Commercial Orbital Transportation Services (COTS) program awarded in February 2008, alongside the company's automated cargo spacecraft, Cygnus. Like other launch vehicles developed by Orbital, Antares leveraged lower-cost, off-the-shelf parts and designs. The first stage is liquid fueled, burning RP-1 (kerosene) and liquid oxygen (LOX). Due to Orbital's limited experience with large liquid stages, the construction was subcontracted to the Ukrainian companies Pivdenne and Pivdenmash. Initially, the Antares 100 series used refurbished NK-33 engines, remnants of the Soviet N1 moon rocket. However, after a catastrophic explosion, the Antares 200 series transitioned to newly built Russian RD-191 engines. Following Russia's in ...
