Ofeq
Ofeq, also spelled Offek or Ofek ( he, אופק, ''lit.'' Horizon) is the designation of a series of Israeli reconnaissance satellites first launched in 1988. Most Ofeq satellites have been carried on top of Shavit 2 launch vehicles from Palmachim Airbase in Israel, on the Mediterranean coast. The low Earth orbit satellites complete one Earth orbit every 90 minutes. The satellite launches made Israel the eighth nation to gain an indigenous launch capability. Both the satellites and the launchers were designed and manufactured by Israel Aerospace Industries (IAI) with Elbit Systems' El-Op division supplying the optical payload. Description While exact technical details and capabilities are classified, it is assumed that the Ofeq satellites have an effective operational lifespan of 1–3 years and ultraviolet and visible imaging sensors (except Ofeq-8 and -10 which utilize synthetic-aperture radar (SAR) for all-weather and nighttime reconnaissance). Some reports place the imagi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palmachim Airbase
The Palmachim Airbase ( he, בָּסִיס חֵיל-הַאֲוִויר פַּלְמַחִים) is an Israeli military facility and spaceport located near the cities of Rishon LeZion and Yavne on the Mediterranean coast. It is named after nearby Kibbutz Palmachim. The base is home to several Israeli Air Force, IAF helicopter and Unmanned aerial vehicle, UAV squadrons, and serves as a rocket launch site for the Arrow (Israeli missile), Arrow missile. Palmachim is also used to launch the Shavit 2, Shavit Outer space, space launch vehicle into retrograde orbit by launching over the Mediterranean, acting as Israel's primary spaceport. The launchpad is situated at . This ensures that rocket debris falls into water, and that the rocket does not fire over regional neighboring countries near Israel that could use the technology. Palmachim is also used to test ballistic missiles, such as the Jericho (missile), Jericho. Recent launches include: * 11 June 2007 - Ofeq-7 satellite * 17 Jan ...

Ofek-11
Ofeq-11, also known as Ofek 11 (Horizon in Hebrew), is part of the Ofeq family of reconnaissance satellites designed and built by Israel Aerospace Industries (IAI) for the Israeli Ministry of Defense. Launch Ofek-11 was launched on 13 September 2016, at 14:38 UTC from the Palmachim Airbase in Israel, two years after the launch of Ofeq-10. It was delivered using IAI's Shavit 2 launcher. Compared to its predecessor, the new satellite features an improved version of El-Op's "Jupiter High-Resolution Imaging System", with resolution increased to 0.5 meter, and uses a new satellite bus - OPSAT-3000 - which is a derivative of the satellite bus used in TecSAR-1. Mission According to reports, the launch initially looked like a success, but about 90 minutes later, engineers realized that while the satellite had entered orbit, not all systems were functioning or responding to instructions. However, after several days of remote repairs, the satellite was operational and taking high-qu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reconnaissance Satellite
A reconnaissance satellite or intelligence satellite (commonly, although unofficially, referred to as a spy satellite) is an Earth observation satellite or communications satellite deployed for military or intelligence applications. The first generation type (i.e., Corona and Zenit) took photographs, then ejected canisters of photographic film which would descend back down into Earth's atmosphere. Corona capsules were retrieved in mid-air as they floated down on parachutes. Later, spacecraft had digital imaging systems and downloaded the images via encrypted radio links. In the United States, most information available about reconnaissance satellites is on programs that existed up to 1972, as this information has been declassified due to its age. Some information about programs before that time is still classified information, and a small amount of information is available on subsequent missions. A few up-to-date reconnaissance satellite images have been declassified o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term ''LEO region'' is also used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Middle East
The Middle East ( ar, الشرق الأوسط, ISO 233: ) is a geopolitical region commonly encompassing Arabian Peninsula, Arabia (including the Arabian Peninsula and Bahrain), Anatolia, Asia Minor (Asian part of Turkey except Hatay Province), East Thrace (European part of Turkey), Egypt, Iran, the Levant (including Syria (region), Ash-Shām and Cyprus), Mesopotamia (modern-day Iraq), and the Socotra Governorate, Socotra Archipelago (a part of Yemen). The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term "Middle East" has led to some confusion over its changing definitions, and has been viewed by some to be discriminatory or too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of Western Asia (including Iran), but without the South Caucasus, and additionally includes all of Egypt (not just the Sina ...

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 pad, launch pads, supported by a missile launch control center, 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 spaceflight, 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 spaceflight, 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-propellant rocket, solid fuel, liquid hydrogen, kerosene, liquid oxygen, or Hypergolic propellants.

Israel Defence Forces
The Israel Defense Forces (IDF; he, צְבָא הַהֲגָנָה לְיִשְׂרָאֵל , ), alternatively referred to by the Hebrew-language acronym (), is the national military of the State of Israel. It consists of three service branches: the Israeli Ground Forces, the Israeli Air Force, and the Israeli Navy. It is the sole military wing of the Israeli security apparatus, and has no civilian jurisdiction within Israel. The IDF is headed by the Chief of the General Staff, who is subordinate to the Israeli Defense Minister. On the orders of David Ben-Gurion, the IDF was formed on 26 May 1948 and began to operate as a conscript military, drawing its initial recruits from the already-existing paramilitaries of the Yishuv—namely Haganah, the Irgun, and Lehi. Since its formation shortly after the Israeli Declaration of Independence, the IDF has participated in every armed conflict involving Israel. While it originally operated on three major fronts—against Lebanon an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
