GK Launch Services
Glavkosmos (russian: Главкосмос) is a subsidiary of the Russian State Space Corporation Roscosmos. On 26 February 1985, the Ministry of General Machine Building of the USSR issued an order that formed the Main Department for the creation and use of space technology for the national economy and scientific research – Glavkosmos of the USSR. Although it was originally envisioned to command all Soviet space activities it worked more as a marketing and coordinating body than an executive agency. The United States imposed sanctions on the company in May 1992, after it agreed in January 1991 to transfer technology for the production of KVD-1 cryogenic rocket engines to the Indian Space Research Organisation. In Soviet times, Glavkosmos was the prime authority for implementing co-operative agreements with foreign bodies, with activities including commercial utilisation of Soviet systems and flying foreign cosmonauts aboard Soviet spacecraft. After the breakup of the Soviet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geostationary Orbit
A geostationary orbit, also referred to as a geosynchronous equatorial orbit''Geostationary orbit'' and ''Geosynchronous (equatorial) orbit'' are used somewhat interchangeably in sources. (GEO), is a circular geosynchronous orbit in altitude above Earth's equator ( in radius from Earth's center) and following the direction of Earth's rotation. An object in such an orbit has an orbital period equal to Earth's rotational period, one sidereal day, and so to ground observers it appears motionless, in a fixed position in the sky. The concept of a geostationary orbit was popularised by the science fiction writer Arthur C. Clarke in the 1940s as a way to revolutionise telecommunications, and the first satellite to be placed in this kind of orbit was launched in 1963. Communications satellites are often placed in a geostationary orbit so that Earth-based satellite antennas do not have to rotate to track them but can be pointed permanently at the position in the sky where the sat ...

Option (finance)
In finance, an option is a contract which conveys to its owner, the ''holder'', the right, but not the obligation, to buy or sell a specific quantity of an underlying asset or instrument at a specified strike price on or before a specified date, depending on the style of the option. Options are typically acquired by purchase, as a form of compensation, or as part of a complex financial transaction. Thus, they are also a form of asset and have a valuation that may depend on a complex relationship between underlying asset price, time until expiration, market volatility, the risk-free rate of interest, and the strike price of the option. Options may be traded between private parties in ''over-the-counter'' (OTC) transactions, or they may be exchange-traded in live, public markets in the form of standardized contracts. Definition and application An option is a contract that allows the holder the right to buy or sell an underlying asset or financial instrument at a specified strike ...

Down Payment
Down payment (also called a deposit in British English), is an initial up-front partial payment for the purchase of expensive items/services such as a car or a house. It is usually paid in cash or equivalent at the time of finalizing the transaction. A loan of some sort is then required to finance the remainder of the payment. The main purposes of a down payment is to ensure that the lending institution has enough capital to create money for a loan in fractional reserve banking systems and to recover some of the balance due on the loan in the event that the borrower defaults. In real estate, the asset is used as collateral in order to secure the loan against default. If the borrower fails to repay the loan, the lender is legally entitled to sell the asset and retain enough of the proceeds to repay the remaining balance on the loan, including fees and interest added. A down payment, in this case, reduces the lender's risk to less than the value of the collateral, making it more like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foton (satellite)
Foton (or Photon) is the project name of two series of Russian science satellite and reentry vehicle programs. Although uncrewed, the design was adapted from the crewed Vostok spacecraft capsule. The primary focus of the Foton project is materials science research, but some missions have also carried experiments for other fields of research including biology. The original Foton series included 12 launches from the Plesetsk Cosmodrome from 1985 to 1999. The second series, under the name Foton-M, incorporates many design improvements over the original Foton, and is still in use. So far, there have been four launch attempts of the Foton-M. The first was in 2002 from the Plesetsk Cosmodrome, which ended in failure due to a problem in the launch vehicle. The last three were from the Baikonur Cosmodrome, in 2005, 2007, and 2014; all were successful. Both the Foton and Foton-M series used Soyuz-U (11A511U and 11A511U2) rockets as launch vehicles.

Kosmos (rocket Family)
The Kosmos (also spelled Cosmos, Russian: ) rockets were a series of Soviet and subsequently Russian rockets, derived from the R-12 and R-14 missiles, the best known of which is the Kosmos-3M, which has made over 440 launches. The Kosmos family contained a number of rockets, both carrier rockets and sounding rockets, for orbital and sub-orbital spaceflight respectively. The first variant, the Kosmos-2I, first flew on 27 October 1961. Over 700 Kosmos rockets have been launched overall. Variants Launches See also *R-7 family The R-7 family of rockets (russian: Р-7) is a series of rockets, derived from the Soviet R-7 Semyorka, the world's first ICBM.

Vostok (rocket Family)
Vostok (Russian: Восток, translated as "East") was a family of rockets derived from the Soviet R-7 Semyorka ICBM and was designed for the human spaceflight programme. This family of rockets launched the first artificial satellite (Sputnik 1) and the first crewed spacecraft (Vostok) in human history. It was a subset of the R-7 family of rockets. On March 18, 1980, a Vostok-2M rocket exploded on its launch pad at Plesetsk during a fueling operation, killing 48 people. An investigation into a similarbut avoidedaccident revealed that the substitution of lead-based for tin-based solder in hydrogen peroxide filters allowed the breakdown of the H2O2, thus causing the resultant explosion. Variants The major versions of the rocket were: * Luna 8K72 – used to launch the early Luna spacecraft * Vostok-L 8K72 – Variant of the Luna, used to launch prototype Vostok spacecraft * Vostok-K 8K72K – a refined version of the above. This was the version actually used for human spac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molniya Orbit
A Molniya orbit ( rus, Молния, p=ˈmolnʲɪjə, a=Ru-молния.ogg, "Lightning") is a type of satellite orbit designed to provide communications and remote sensing coverage over high latitudes. It is a highly elliptical orbit with an inclination of 63.4 degrees, an argument of perigee of 270 degrees, and an orbital period of approximately half a sidereal day. The name comes from the ''Molniya'' satellites, a series of Soviet/Russian civilian and military communications satellites which have used this type of orbit since the mid-1960s. The Molniya orbit has a long dwell time over the hemisphere of interest, while moving very quickly over the other. In practice, this places it over either Russia or Canada for the majority of its orbit, providing a high angle of view to communications and monitoring satellites covering these high-latitude areas. Geostationary orbits, which are necessarily inclined over the equator, can only view these regions from a low angle, hamperin ...
