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.

AMOS-6 (satellite)
AMOS-6 was an Israeli communications satellite, one of the Spacecom AMOS series, that was built by Israel Aerospace Industries (IAI), a defense and aerospace company. AMOS-6 was intended to be launched on flight 29 of a SpaceX Falcon 9 to geostationary transfer orbit (GTO) on 3 September 2016. On 1 September 2016, during the run-up to a static fire test, there was an anomaly on the launch pad, resulting in an explosion and the loss of the vehicle and AMOS-6. There were no injuries. Terminology AMOS stands for "Affordable Modular Optimized Satellite" and is also an allusion to the prophet Amos. This spacecraft is the second implementation of the AMOS-4000 satellite bus, the first was the AMOS-4. It is one of a AMOS series of satellites built by Israel Aerospace Industries (IAI). History Spacecom, the AMOS satellites operator, announced in June 2012 that it had signed a US$195 million contract to build AMOS-6, the newest addition to the AMOS constellation, with Israe ...

Spacecom
Spacecom, or Space Communication (), is an Israeli communications satellite operator in the Middle East, European Union and North America headquartered in the city of Ramat Gan, Israel. Spacecom operates two satellites at orbital position 4° West – AMOS-3 and AMOS-7, one satellite at orbital position 65° East – AMOS-4, and one satellite at orbital position 17° East – AMOS-5. History Spacecom was established in 1993 with a defined goal of marketing AMOS-1, a newly built communication satellite manufactured by Israel Aerospace Industries (IAI). In 2003, Spacecom launched its second satellite, AMOS-2, owned entirely by the company. In 2008, the AMOS-3 satellite was launched to replace AMOS-1 and to increase coverage and traffic abilities. Until 2005, Spacecom was a private company controlled by four companies, including IAI and Eurocom Group. It went public on the Tel Aviv Stock Exchange in 2005. In August 2016, Spacecom shareholders agreed to sell the company fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AMOS (satellite Bus)
The AMOS (Hebrew: ), an acronym for Affordable Modular Optimized Satellite, is a family of light weight satellite bus for geostationary orbit communications satellite designed and manufactured by Israel Aerospace Industries (IAI) of Israel. Families Little is known regarding the different variations. But it is known of at least two built versions and a third in development. AMOS (original) The AMOS bus is a lightweight version used for satellites between , with 800 to 1700 watts of power. The satellite bus started with the AMOS-1, the smallest of all the family, and increased mass, payload successively in the AMOS-2 and AMOS-3. AMOS 4000 The AMOS 4000 platform is the second generation, a much bigger and sophisticated satellite bus. It is prepared for satellites weighing between and with power generation between 3 and 12 kW.

AMOS-5 (satellite)
Amos-5 ( he, עמוס 5) was an Israeli commercial communications satellite, part of the AMOS series of satellites. It was developed and built for Spacecom by Information Satellite Systems Reshetnev (NPO PM), the largest Russian satellite producer, at a cost of US$157 million. The satellite was positioned at the 17° East longitude in the geostationary orbit. It was launched on 11 December 2011, 11:17:00 UTC from Baikonur Cosmodrome, Kazakhstan, atop a Proton-M / Briz-M launch vehicle. It provided coverage over the continent of Africa, as well as Europe and the Middle East. Mission Following failure of power generator 1, generator 2 was activated in May 2012. Power generator 2 also developed faults in September 2012 and October 2013 and the satellite's initial lifespan of 15 years was expected to be shortened by 11 months. However all communications with the AMOS-5 satellite were lost on 21 November 2015. The satellite was visualized in its expected location, moving in an ...

Zenit-3SLB
The Zenit 3SLB or Zenit-3M is a Ukrainian expendable carrier rocket derived from the Zenit-2SB. It is a member of the Zenit family of rockets, which were designed by the Yuzhnoye Design Office. Produced at Yuzhmash, the rocket is a modified version of the Zenit-3SL, designed to be launched from a conventional launch pad rather than the Sea Launch Ocean Odyssey platform. Most of components of the rocket are produced in Russia. Launches of Zenit-3SLB rockets are conducted from Site 45/1 at the Baikonur Cosmodrome. Commercial launches are conducted by Land Launch, and use the designation 3SLB, whilst launches conducted by Federal Space Agency Roskosmos or the Russian Space Forces will use the designation 3M. It consists of a Zenit 2SB (Zenit-2M) core vehicle, with a Block DM-SLB upper stage by RSC Energia (Russia). The rocket's fairing is developed by Lavochkin (Khimki, Moscow, Russia). The launch services are provided by "Land Launch", a subsidiary of Sea Launch, and Space Int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communicat ...

Falcon 9
Falcon 9 is a partially reusable medium lift launch vehicle that can carry cargo and crew into Earth orbit, produced by American aerospace company SpaceX. The rocket has two stages. The first (booster) stage carries the second stage and payload to a certain altitude, after which the second stage lifts the payload to its ultimate destination. The rocket evolved through several versions. V1.0 flew from 2010–2013, V1.1 flew from 2013–2016, while V1.2 Full Thrust first launched in 2015, encompassing the Block 5 variant, flying since May 2018. The booster is capable of landing vertically to facilitate reuse. This feat was first achieved on flight 20 in December 2015. Since then, SpaceX has successfully landed boosters over 100 times. Individual boosters have flown as many as 15 flights. Both stages are powered by SpaceX Merlin engines, using cryogenic liquid oxygen and rocket-grade kerosene ( RP-1) as propellants.

Launch Vehicle
A launch vehicle or carrier rocket is a rocket designed to carry a payload (spacecraft or satellites) from the Earth's surface to outer space. Most launch vehicles operate from a launch pads, supported by a launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to large operating costs. An orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles are multistage rockets which use chemical propellants such as solid fuel, liquid hydrogen, kerosene, liquid oxygen, or Hypergolic propellants. Launch vehicles are classified by their orbital payload capacity, ranging from small-, medium-, heavy- to super-heavy lift ...
