Land Launch
Land Launch refers to a service product of Sea Launch SA. There is no entity or company called Land Launch. Sea Launch created the Land Launch offering to address lighter satellites directly into geosynchronous orbit or into geosynchronous transfer orbit, while Sea Launch continues to address the heavy satellite launch market. In 2002, Sea Launch created Land Launch with its Russian and Ukrainian partners. The Russian and Ukrainian partners formed a Russian company Space International Services (SIS) to provide the launch services and launch operations. While the Sea Launch company maintains the rights to market Land Launch to the commercial community, the new entity SIS can market launch services to government customers. Land Launch uses Zenit rockets to conduct commercial satellite launches from the Baikonur Cosmodrome Site 45/1 in Kazakhstan. Land Launch missions differ from Sea Launch missions in that the Zenit-3SLB is used, as opposed to the Zenit-3SL. The Zenit-3SLB utili ...

AMOS-60
AMOS-3, also known as AMOS-60, is an Israeli communications satellite operated by Spacecom Satellite Communications. History Spacecom Satellite Communications has signed an agreement in September 2005 with Israel Aerospace Industries (IAI) to buy its third satellite, AMOS-3, from the Israeli defense contractor. Satellite description The satellite is powered by twin solar panels, and is based on the Israeli AMOS Bus. It replaced AMOS-1 in geosynchronous orbit at 4° West. AMOS-3 carries fourteen Ku-band / Ka-band transponders, and is expected to have an on-orbit lifetime of 18 years. Launch It was launched atop the maiden flight of the Zenit-3SLB launch vehicle, the first launch contracted by the Land Launch organisation. The launch was originally scheduled to occur in 2007, and later March 2008, however this was delayed until 24 April 2008. The launch attempt on 24 April 2008 was scrubbed for "technical reasons". This was later determined to be a problem with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expendable Launch System
An expendable launch system (or expendable launch vehicle/ELV) is a launch vehicle that can be launched only once, after which its components are either destroyed during reentry or discarded in space. ELVs typically consist of several rocket stages that are discarded sequentially as their fuel is exhausted and the vehicle gains altitude and speed. As of 2022, most satellites and human spacecraft are currently launched on ELVs. ELVs are simpler in design than reusable launch systems and therefore may have a lower production cost. Furthermore, an ELV can use its entire fuel supply to accelerate its payload, offering greater payloads. ELVs are proven technology in widespread use for many decades. ELVs are usable only once, and therefore have a significantly higher per-launch cost than modern (post-STS) reusable vehicles. Current operators Arianespace China ISRO JAXA Roscosmos United States Several governmental agencies of the United States purchase ELV launches. NASA is ...

AMOS-4
AMOS-4 is an Israeli commercial communications satellite, operated by Spacecom Satellite Communications, Tel Aviv-based, part of the AMOS series of satellites. History Spacecom, the AMOS satellites operator, announced in 2007 that it has signed an agreement to build and launch AMOS-4, with Israel Aerospace Industries. IAI constructed the satellite for approximately US$365 million. Spacecom paid US$100 million for AMOS-4. The Israeli government paid Spacecom US$265 million generated from a pre-launch deal to supply it with services on AMOS-4 over the satellite's full 12 year life span. AMOS-4 was originally considered as a candidate for launch on a SpaceX Falcon-9 launch vehicle. The satellite was later assigned to a Zenit-3SLB launch vehicle and was finally launched in August 2013. Launch It lifted off on 31 August 2013, 20:05:00 UTC from Baikonur Cosmodrome, Kazakhstan. The geostationary satellite provides direct-to-home television broadcasting, multimedia, broadband I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Telstar
Telstar is the name of various communications satellites. The first two Telstar satellites were experimental and nearly identical. Telstar 1 launched on top of a Thor-Delta rocket on July 10, 1962. It successfully relayed through space the first television pictures, telephone calls, and telegraph images, and provided the first live transatlantic television feed. Telstar 2 launched May 7, 1963. Telstar 1 and 2—though no longer functional—still orbit the Earth. Description Belonging to AT&T, the original Telstar was part of a multi-national agreement among AT&T (USA), Bell Telephone Laboratories (USA), NASA (USA), GPO (United Kingdom) and the National PTT (France) to develop experimental satellite communications over the Atlantic Ocean. Bell Labs held a contract with NASA, paying the agency for each launch, independent of success.

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 ...

Zenit-2M
The Zenit-2M, Zenit-2SB, Zenit-2SLB or Zenit-2FG was a Ukrainian expendable carrier rocket derived from the Zenit-3SL. It was a member of the Zenit family of rockets, which were designed by the Yuzhmash. Development The Zenit 2M was a modernised version of the Zenit-2, incorporating modifications and upgrades made to the design for the Sea Launch programme. Launches of Zenit-2M rockets were conducted from Baikonur Cosmodrome Site 45/1. Commercial launches are conducted by Land Launch, and use the designation 2SLB, however as of 2011, no commercial launches have been ordered. Launches conducted by Roskosmos or the Russian Space Forces use the designation 2M. The designation 2SB can also be applied to the rocket when it is being used as part of a larger vehicle, such as the Zenit-3SLB. The first launch of a Zenit-2M occurred on 29 June 2007, carrying the last Tselina-2 ELINT satellite for the Russian Space Forces, Tselina-2 satellites having been previously launched by older Ze ...
