170-518: The Israel Space Agency ( ISA ; Hebrew : סוכנות החלל הישראלית , Sokhnut heKhalal haYisraelit ) is a governmental body, a part of Israel 's Ministry of Science and Technology , that coordinates all Israeli space research programs with scientific and commercial goals. The agency was founded by the theoretical physicist Yuval Ne'eman in 1983 to replace the National Committee for Space Research , which had established in 1960 to set up
340-591: A Diamant A rocket launched from the CIEES site at Hammaguir , Algeria . With Astérix, France became the sixth country to have an artificial satellite. Early satellites were built to unique designs. With advancements in technology, multiple satellites began to be built on single model platforms called satellite buses . The first standardized satellite bus design was the HS-333 geosynchronous (GEO) communication satellite launched in 1972. Beginning in 1997, FreeFlyer
510-414: A catalyst . The most commonly used propellant mixtures on satellites are hydrazine -based monopropellants or monomethylhydrazine – dinitrogen tetroxide bipropellants. Ion thrusters on satellites usually are Hall-effect thrusters , which generate thrust by accelerating positive ions through a negatively-charged grid. Ion propulsion is more efficient propellant-wise than chemical propulsion but its thrust
680-654: 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
850-813: A halo orbit , three for a Lissajous orbit ). Earth observation satellites gather information for reconnaissance , mapping , monitoring the weather , ocean, forest, etc. Space telescopes take advantage of outer space's near perfect vacuum to observe objects with the entire electromagnetic spectrum . Because satellites can see a large portion of the Earth at once, communications satellites can relay information to remote places. The signal delay from satellites and their orbit's predictability are used in satellite navigation systems, such as GPS. Space probes are satellites designed for robotic space exploration outside of Earth, and space stations are in essence crewed satellites. The first artificial satellite launched into
1020-637: A low Earth orbit . The Shavit launcher is developed by Malam factory, one of four factories in the IAI Electronics Group. The factory is very experienced in development, assembling, testing and operating system for use in space. The Shavit is a triple-stage launcher solid propellant booster based on the 2-stage Jericho-II ballistic missile . The first and second stage engines are manufactured by Ta'as, and use solid fuel. The third stage engines are manufactured by Rafael Advanced Defense Systems . The next generation Shavit rockets, now called

Communications satellites are used for television , telephone , radio , internet , and military applications. Many communications satellites are in geostationary orbit 22,236 miles (35,785 km) above the equator , so that the satellite appears stationary at
1360-685: A Hebrew form. Medieval Hebrew added 6421 words to (Modern) Hebrew. The approximate number of new lexical items in Israeli is 17,000 (cf. 14,762 in Even-Shoshan 1970 [...]). With the inclusion of foreign and technical terms [...], the total number of Israeli words, including words of biblical, rabbinic and medieval descent, is more than 60,000. In Israel, Modern Hebrew is currently taught in institutions called Ulpanim (singular: Ulpan). There are government-owned, as well as private, Ulpanim offering online courses and face-to-face programs. Modern Hebrew

This expanded on potential scientific uses for satellite vehicles and was followed in June 1955 with "The Scientific Use of an Artificial Satellite", by H. K. Kallmann and W. W. Kellogg. The first artificial satellite was Sputnik 1 , launched by the Soviet Union on 4 October 1957 under the Sputnik program , with Sergei Korolev as chief designer. Sputnik 1 helped to identify
1700-453: A U.S. Scout rocket from Wallops Island (Virginia, United States) with an Italian launch team trained by NASA . In similar occasions, almost all further first national satellites were launched by foreign rockets. France was the third country to launch a satellite on its own rocket. On 26 November 1965, the Astérix or A-1 (initially conceptualized as FR.2 or FR-2), was put into orbit by
1870-405: A bandwidth of tens of megahertz. Satellites are placed from the surface to the orbit by launch vehicles , high enough to avoid orbital decay by the atmosphere . Satellites can then change or maintain the orbit by propulsion , usually by chemical or ion thrusters . As of 2018, about 90% of the satellites orbiting the Earth are in low Earth orbit or geostationary orbit ; geostationary means

#17327802347122040-595: A century ago, was fluent enough in this idiom to be able to follow the Mishna Berurah without any trouble." Hebrew has been revived several times as a literary language, most significantly by the Haskalah (Enlightenment) movement of early and mid-19th-century Germany. In the early 19th century, a form of spoken Hebrew had emerged in the markets of Jerusalem between Jews of different linguistic backgrounds to communicate for commercial purposes. This Hebrew dialect
2210-661: A corollary Hebrew ceased to function as a spoken language around the same time. Moshe Zvi Segal , Joseph Klausner and Ben Yehuda are notable exceptions to this view. During the latter half of the 20th century, accumulating archaeological evidence and especially linguistic analysis of the Dead Sea Scrolls has disproven that view. The Dead Sea Scrolls, uncovered in 1946–1948 near Qumran revealed ancient Jewish texts overwhelmingly in Hebrew, not Aramaic. The Qumran scrolls indicate that Hebrew texts were readily understandable to
2380-579: A distinct style of philosophical Hebrew. This is used in the translations made by the Ibn Tibbon family. (Original Jewish philosophical works were usually written in Arabic. ) Another important influence was Maimonides , who developed a simple style based on Mishnaic Hebrew for use in his law code, the Mishneh Torah . Subsequent rabbinic literature is written in a blend between this style and
2550-594: A gradually accepted movement. It was not, however, until the 1904–1914 Second Aliyah that Hebrew had caught real momentum in Ottoman Palestine with the more highly organized enterprises set forth by the new group of immigrants. When the British Mandate of Palestine recognized Hebrew as one of the country's three official languages (English, Arabic, and Hebrew, in 1922), its new formal status contributed to its diffusion. A constructed modern language with
2720-630: A hitch. Following a setback with Ofeq-4 , Ofeq-5 was successfully launched in May 2002. To date, twelve such satellites in the Ofeq reconnaissance satellites series were developed and launched to Low Earth Orbit . The most recent, Ofek 16, was launched July 6, 2020. The AMOS is a series of communications satellites. The AMOS satellites are by the Israel Aerospace Industries and are operated by Spacecom once in orbit. The AMOS-1 ,
2890-581: A joint mission by Israel (ISA) and the Italy Space Agency ( ASI ) has a budget of $ 116 million. The budget allocated annually for the Israeli military program as well as commercial programs are managed on different budgets. The Israel Space Agency has had a long history of satellite programs both for reconnaissance and commercial purposes. Its first satellite, the Ofeq -1 was launched on September 19, 1988, from Palmachim Airbase in Israel. Since
3060-468: A literary language down through the Byzantine period from the 4th century CE. The exact roles of Aramaic and Hebrew remain hotly debated. A trilingual scenario has been proposed for the land of Israel. Hebrew functioned as the local mother tongue with powerful ties to Israel's history, origins and golden age and as the language of Israel's religion; Aramaic functioned as the international language with
3230-536: A literary language, especially in Spain, as the language of commerce between Jews of different native languages, and as the liturgical language of Judaism, evolving various dialects of literary Medieval Hebrew , until its revival as a spoken language in the late 19th century. In May 2023, Scott Stripling published the finding of what he claims to be the oldest known Hebrew inscription, a curse tablet found at Mount Ebal , dated from around 3200 years ago. The presence of
3400-484: 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 constellations . Because of the high launch cost to space, most satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with
3570-418: A satellite's lifetime. Resource use is difficult to monitor and quantify for satellites and launch vehicles due to their commercially sensitive nature. However, aluminium is a preferred metal in satellite construction due to its lightweight and relative cheapness and typically constitutes around 40% of a satellite's mass. Through mining and refining, aluminium has numerous negative environmental impacts and

#17327802347123740-548: A set of dialects evolving out of Late Biblical Hebrew and into Mishnaic Hebrew, thus including elements from both but remaining distinct from either. By the start of the Byzantine Period in the 4th century CE, Classical Hebrew ceased as a regularly spoken language, roughly a century after the publication of the Mishnah, apparently declining since the aftermath of the catastrophic Bar Kokhba revolt around 135 CE. In
3910-668: A spoken language, it continued to be used as a lingua franca among scholars and Jews traveling in foreign countries. After the 2nd century CE when the Roman Empire exiled most of the Jewish population of Jerusalem following the Bar Kokhba revolt , they adapted to the societies in which they found themselves, yet letters, contracts, commerce, science, philosophy, medicine, poetry and laws continued to be written mostly in Hebrew, which adapted by borrowing and inventing terms. After
4080-449: A thin cable called a tether . Recovery satellites are satellites that provide a recovery of reconnaissance, biological, space-production and other payloads from orbit to Earth. Biosatellites are satellites designed to carry living organisms, generally for scientific experimentation. Space-based solar power satellites are proposed satellites that would collect energy from sunlight and transmit it for use on Earth or other places. Since
4250-600: A thought experiment by Isaac Newton to explain the motion of natural satellites , in his Philosophiæ Naturalis Principia Mathematica (1687). The first fictional depiction of a satellite being launched into orbit was a short story by Edward Everett Hale , " The Brick Moon " (1869). The idea surfaced again in Jules Verne 's The Begum's Fortune (1879). In 1903, Konstantin Tsiolkovsky (1857–1935) published Exploring Space Using Jet Propulsion Devices , which
4420-472: A truly Semitic vocabulary and written appearance, although often European in phonology , was to take its place among the current languages of the nations. While many saw his work as fanciful or even blasphemous (because Hebrew was the holy language of the Torah and therefore some thought that it should not be used to discuss everyday matters), many soon understood the need for a common language amongst Jews of
4590-479: A university-based research project from Tel Aviv University in the early 1960s. In 1960, the National Committee for Space Research (NCSR) was formed by the Israel Academy of Sciences and Humanities . The committee was formed to increase research activities across the academic communities in Israel. While at the time establishing a space program was not particularly one of its goals, during the 1960s through
4760-558: A vernacular in Judea until it was displaced by Aramaic, probably in the 3rd century CE. Certain Sadducee , Pharisee , Scribe , Hermit, Zealot and Priest classes maintained an insistence on Hebrew, and all Jews maintained their identity with Hebrew songs and simple quotations from Hebrew texts. While there is no doubt that at a certain point, Hebrew was displaced as the everyday spoken language of most Jews, and that its chief successor in

A regional dialect of the Canaanite languages , it was natively spoken by the Israelites and remained in regular use as a first language until after 200 CE and as the liturgical language of Judaism (since the Second Temple period ) and Samaritanism . The language was revived as a spoken language in the 19th century, and
5270-549: Is a space launch vehicle capable of sending payload into low Earth orbit . The Shavit launcher has been used to send every Ofeq satellite to date. The development of the Shavit began in 1983 and its operational capabilities were proven on three successful launches of the Ofek satellites on September 19, 1988; April 3, 1990; and April 5, 1995. The Shavit launchers allows low-cost and high-reliability launch of micro/mini satellites to

New words and expressions were adapted as neologisms from the large corpus of Hebrew writings since the Hebrew Bible, or borrowed from Arabic (mainly by Ben-Yehuda) and older Aramaic and Latin. Many new words were either borrowed from or coined after European languages, especially English, Russian, German, and French. Modern Hebrew became an official language in British-ruled Palestine in 1921 (along with English and Arabic), and then in 1948 became an official language of
12750-604: The 6th century BCE, during the time of the Babylonian captivity . For this reason, Hebrew has been referred to by Jews as Lashon Hakodesh ( לְשׁוֹן הַקֹּדֶש , lit. ' the holy tongue ' or ' the tongue [of] holiness ' ) since ancient times. The language was not referred to by the name Hebrew in the Bible , but as Yehudit ( transl. ' Judean ' ) or Səpaṯ Kəna'an ( transl. "the language of Canaan " ). Mishnah Gittin 9:8 refers to
12920-766: The Aramaized Rabbinic Hebrew of the Talmud. Hebrew persevered through the ages as the main language for written purposes by all Jewish communities around the world for a large range of uses—not only liturgy, but also poetry, philosophy, science and medicine, commerce, daily correspondence and contracts. There have been many deviations from this generalization such as Bar Kokhba 's letters to his lieutenants, which were mostly in Aramaic, and Maimonides' writings, which were mostly in Arabic; but overall, Hebrew did not cease to be used for such purposes. For example,
13090-687: The British Mandate who at the turn of the 20th century were arriving in large numbers from diverse countries and speaking different languages. A Committee of the Hebrew Language was established. After the establishment of Israel, it became the Academy of the Hebrew Language . The results of Ben-Yehuda's lexicographical work were published in a dictionary ( The Complete Dictionary of Ancient and Modern Hebrew , Ben-Yehuda Dictionary ). The seeds of Ben-Yehuda's work fell on fertile ground, and by
13260-457: The Earth's vegetation , atmospheric trace gas content, sea state, ocean color, and ice fields. By monitoring vegetation changes over time, droughts can be monitored by comparing the current vegetation state to its long term average. Anthropogenic emissions can be monitored by evaluating data of tropospheric NO 2 and SO 2 . A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via
13430-417: The Earth's orbit was the Soviet Union 's Sputnik 1 , on October 4, 1957. As of December 31, 2022, there are 6,718 operational satellites in the Earth's orbit, of which 4,529 belong to the United States (3,996 commercial), 590 belong to China, 174 belong to Russia, and 1,425 belong to other nations. The first published mathematical study of the possibility of an artificial satellite was Newton's cannonball ,
13600-500: The Earth, called remote sensing . Most Earth observation satellites are placed in low Earth orbit for a high data resolution, though some are placed in a geostationary orbit for an uninterrupted coverage. Some satellites are placed in a Sun-synchronous orbit to have consistent lighting and obtain a total view of the Earth. Depending on the satellites' functions, they might have a normal camera , radar , lidar , photometer , or atmospheric instruments. Earth observation satellite's data
13770-486: The Emirates. OPsat is a next generation high resolution optical observation satellite for reconnaissance purposes. It is designed to be a 300 kilograms (660 lb) satellite capable of detecting objects of about 50 centimeters in diameter. It will be equipped with a camera with CCD / TDI sensors, producing both panchromatic imagery at a very high resolution and multispectral imagery at a medium resolution. The satellite
13940-526: The Great conquered Babylon, he allowed the Jewish people to return from captivity. In time, a local version of Aramaic came to be spoken in Israel alongside Hebrew. By the beginning of the Common Era , Aramaic was the primary colloquial language of Samarian , Babylonian and Galileean Jews, and western and intellectual Jews spoke Greek , but a form of so-called Rabbinic Hebrew continued to be used as
14110-432: The Hebrew name of god , Yahweh, as three letters, Yod-Heh-Vav (YHV), according to the author and his team meant that the tablet is Hebrew and not Canaanite. However, practically all professional archeologists and epigraphers apart from Stripling's team claim that there is no text on this object. In July 2008, Israeli archaeologist Yossi Garfinkel discovered a ceramic shard at Khirbet Qeiyafa that he claimed may be
14280-602: The Hebrew Bible. The Masoretes inherited a biblical text whose letters were considered too sacred to be altered, so their markings were in the form of pointing in and around the letters. The Syriac alphabet , precursor to the Arabic alphabet , also developed vowel pointing systems around this time. The Aleppo Codex , a Hebrew Bible with the Masoretic pointing, was written in the 10th century, likely in Tiberias, and survives into
14450-725: The Internet to the research community and to the general public free of charge. This research, headed by Pinhas Alpert, is funded by the ISA as a part of the Space Scientific and Technological Infrastructure Development program. The node is integrated with NASA's Global Information System which includes Earth Observing Science Data and Information System. It also contains Remote Sensing Data from NASA and NOAA satellites, and data from other sources such as meteorological RADAR and readings from meteorological stations. Information collected by
14620-660: The Israeli government authorized the Minister of Science and Technology Yuval Ne'eman to establish an Israeli Space Agency with the goal of advancing Israel's space program, unlike the NCSR which was primarily used for feasibility and infrastructure studies. In July 1983, the ISA was officially founded in Tel Aviv to coordinate the nation's space program in affiliation to the Ministry of Science, Culture & Sport , and Dror Sadeh
14790-454: The Israeli population speaks Hebrew as a native language, while most of the rest speak it fluently. In 2013 Hebrew was the native language of 49% of Israelis over the age of 20, with Russian , Arabic , French , English , Yiddish and Ladino being the native tongues of most of the rest. Some 26% of immigrants from the former Soviet Union and 12% of Arabs reported speaking Hebrew poorly or not at all. Steps have been taken to keep Hebrew
14960-477: The Middle East was the closely related Aramaic language, then Greek , scholarly opinions on the exact dating of that shift have changed very much. In the first half of the 20th century, most scholars followed Abraham Geiger and Gustaf Dalman in thinking that Aramaic became a spoken language in the land of Israel as early as the beginning of Israel's Hellenistic period in the 4th century BCE, and that as
15130-553: The Moon and the Sun. Satellites utilize ultra-white reflective coatings to prevent damage from UV radiation. Without orbit and orientation control, satellites in orbit will not be able to communicate with ground stations on the Earth. Chemical thrusters on satellites usually use monopropellant (one-part) or bipropellant (two-parts) that are hypergolic . Hypergolic means able to combust spontaneously when in contact with each other or to
15300-597: The Shavit-2 are being developed. The Shavit-2 is said to be made available for commercial launches in the near future. The Israel Space Agency and the Israeli Air Force (IAF) jointly operate the spaceport located south of Palmachim Airbase . The IAF with its 151 Squadron for missile testing uses it to test its Jericho and Arrow missiles. Due to Israel's geographic location and hostile relations with surrounding countries, launches take off due west, over
15470-621: The Talmud, the Gemara , generally comments on the Mishnah and Baraitot in two forms of Aramaic. Nevertheless, Hebrew survived as a liturgical and literary language in the form of later Amoraic Hebrew, which occasionally appears in the text of the Gemara, particularly in the Jerusalem Talmud and the classical aggadah midrashes . Hebrew was always regarded as the language of Israel's religion, history and national pride, and after it faded as
15640-460: The Talmud, various regional literary dialects of Medieval Hebrew evolved. The most important is Tiberian Hebrew or Masoretic Hebrew, a local dialect of Tiberias in Galilee that became the standard for vocalizing the Hebrew Bible and thus still influences all other regional dialects of Hebrew. This Tiberian Hebrew from the 7th to 10th century CE is sometimes called "Biblical Hebrew" because it
15810-488: The ability to speak the language and attempted to promote its use. According to the Jerusalem Talmud , Megillah 1:9: "Rebbi Jonathan from Bet Guvrrin said, four languages are appropriate that the world should use them, and they are these: The Foreign Language (Greek) for song, Latin for war, Syriac for elegies, Hebrew for speech. Some are saying, also Assyrian (Hebrew script) for writing." The later section of
15980-478: The above phases of spoken Classical Hebrew are simplified into "Biblical Hebrew" (including several dialects from the 10th century BCE to 2nd century BCE and extant in certain Dead Sea Scrolls) and "Mishnaic Hebrew" (including several dialects from the 3rd century BCE to the 3rd century CE and extant in certain other Dead Sea Scrolls). However, today most Hebrew linguists classify Dead Sea Scroll Hebrew as
16150-429: The agency's space activities in research and development. The budget does not include launch vehicle development and most satellite programs. Typically such programs get funded on a project-by-project basis. For example, Project Venus , a cooperative program by Israel (ISA) and France ( CNES ) which is set to launch in 2014 has a $ 50 million budget. The Spaceborne Hyperspectral Applicative Land and Ocean Mission ( SHALOM ),
16320-541: The astronauts' health, electronic and navigational systems in aircraft flying in extremely high altitudes and ground power systems. The Emilio Segre' Observatory (ESOI) is a cosmic radiation observatory prepared via a joint collaboration with Italy. It was transported to Mount Hermon , Israel in June 1998. The observatory was named after the Italian physicist and Nobel laureate Emilio G. Segrè . The Israel Space Agency - Middle East Interactive Data Archive (ISA-MEIDA)
16490-455: The atmosphere. Given the current surge in satellites in the sky, soon hundreds of satellites may be clearly visible to the human eye at dark sites. It is estimated that the overall levels of diffuse brightness of the night skies has increased by up to 10% above natural levels. This has the potential to confuse organisms, like insects and night-migrating birds, that use celestial patterns for migration and orientation. The impact this might have
16660-603: The atmosphere. For example, SpaceX Starlink satellites, the first large satellite internet constellation to exceed 1000 active satellites on orbit in 2020, are designed to be 100% demisable and burn up completely on their atmospheric reentry at the end of their life, or in the event of an early satellite failure. In different periods, many countries, such as Algeria , Argentina , Australia , Austria , Brazil , Canada , Chile , China , Denmark , Egypt , Finland , France , Germany , India , Iran , Israel , Italy , Japan , Kazakhstan , South Korea , Malaysia , Mexico ,
16830-506: The average Jew, and that the language had evolved since Biblical times as spoken languages do. Recent scholarship recognizes that reports of Jews speaking in Aramaic indicate a multilingual society, not necessarily the primary language spoken. Alongside Aramaic, Hebrew co-existed within Israel as a spoken language. Most scholars now date the demise of Hebrew as a spoken language to the end of the Roman period , or about 200 CE. It continued on as
17000-486: The beginning of the 20th century, Hebrew was well on its way to becoming the main language of the Jewish population of both Ottoman and British Palestine. At the time, members of the Old Yishuv and a very few Hasidic sects, most notably those under the auspices of Satmar , refused to speak Hebrew and spoke only Yiddish. In the Soviet Union, the use of Hebrew, along with other Jewish cultural and religious activities,
17170-447: The capability to destroy live satellites. The environmental impact of satellites is not currently well understood as they were previously assumed to be benign due to the rarity of satellite launches. However, the exponential increase and projected growth of satellite launches are bringing the issue into consideration. The main issues are resource use and the release of pollutants into the atmosphere which can happen at different stages of
17340-602: The composition of 1 Maccabees in archaizing Hebrew, Hasmonean coinage under John Hyrcanus (134-104 BCE), and coins from both the Great Revolt and Bar Kokhba Revolt featuring exclusively Hebrew and Palaeo-Hebrew script inscriptions. This deliberate use of Hebrew and Paleo-Hebrew script in official contexts, despite limited literacy, served as a symbol of Jewish nationalism and political independence. The Christian New Testament contains some Semitic place names and quotes. The language of such Semitic glosses (and in general
17510-410: The content of Hebrew inscriptions suggests that the written texts closely mirror the spoken language of that time. Scholars debate the degree to which Hebrew was a spoken vernacular in ancient times following the Babylonian exile when the predominant international language in the region was Old Aramaic . Hebrew was extinct as a colloquial language by late antiquity , but it continued to be used as
17680-507: The defense department, and in 1984, Defense Minister Moshe Arens insisted on resuming the program. In 1984 the National Space Knowledge Center was established in cooperation with Israel Aircraft Industries ; a contract was signed between IAI and Ministry of Defence for the development of the needed infrastructure and of Israel's first observation satellite . This came to fruition in 1988 when Israel launched
17850-551: The density of high atmospheric layers through measurement of its orbital change and provided data on radio-signal distribution in the ionosphere . The unanticipated announcement of Sputnik 1's success precipitated the Sputnik crisis in the United States and ignited the so-called Space Race within the Cold War . In the context of activities planned for the International Geophysical Year (1957–1958),
18020-568: The dialects of Classical Hebrew that functioned as a living language in the land of Israel. A transitional form of the language occurs in the other works of Tannaitic literature dating from the century beginning with the completion of the Mishnah. These include the halachic Midrashim ( Sifra , Sifre , Mekhilta etc.) and the expanded collection of Mishnah-related material known as the Tosefta . The Talmud contains excerpts from these works, as well as further Tannaitic material not attested elsewhere;
18190-564: The discovery of several tens of new asteroids and is now intensely used to study asteroid rotation and asteroid pair properties. Following the cessation of funding from ISA, the asteroid studies are continuing at the Wise Observatory with no specific financial support. The Israel Cosmic Ray Center (ICRC) was established in November 1997 with support from the Israel Space Agency and with affiliation to Tel Aviv University and
18360-546: The discovery of the Earth's Van Allen radiation belts . The TIROS-1 spacecraft, launched on April 1, 1960, as part of NASA's Television Infrared Observation Satellite (TIROS) program, sent back the first television footage of weather patterns to be taken from space. In June 1961, three and a half years after the launch of Sputnik 1, the United States Space Surveillance Network cataloged 115 Earth-orbiting satellites. While Canada
18530-423: The earliest Hebrew writing yet discovered, dating from around 3,000 years ago. Hebrew University archaeologist Amihai Mazar said that the inscription was "proto-Canaanite" but cautioned that "[t]he differentiation between the scripts, and between the languages themselves in that period, remains unclear", and suggested that calling the text Hebrew might be going too far. The Gezer calendar also dates back to
18700-513: The earliest speakers of Modern Hebrew had Yiddish as their native language and often introduced calques from Yiddish and phono-semantic matchings of international words. Despite using Sephardic Hebrew pronunciation as its primary basis, modern Israeli Hebrew has adapted to Ashkenazi Hebrew phonology in some respects, mainly the following: The vocabulary of Israeli Hebrew is much larger than that of earlier periods. According to Ghil'ad Zuckermann : The number of attested Biblical Hebrew words
18870-532: The early 6th century BCE, the Neo-Babylonian Empire conquered the ancient Kingdom of Judah , destroying much of Jerusalem and exiling its population far to the east in Babylon . During the Babylonian captivity , many Israelites learned Aramaic, the closely related Semitic language of their captors. Thus, for a significant period, the Jewish elite became influenced by Aramaic. After Cyrus
19040-484: The earth's climate. After deorbiting 70% of satellites end up in the ocean and are rarely recovered. Using wood as an alternative material has been posited in order to reduce pollution and debris from satellites that reenter the atmosphere. Space debris pose dangers to the spacecraft (including satellites) in or crossing geocentric orbits and have the potential to drive a Kessler syndrome which could potentially curtail humanity from conducting space endeavors in
19210-711: The first Middle East printing press, in Safed (modern Israel), produced a small number of books in Hebrew in 1577, which were then sold to the nearby Jewish world. This meant not only that well-educated Jews in all parts of the world could correspond in a mutually intelligible language, and that books and legal documents published or written in any part of the world could be read by Jews in all other parts, but that an educated Jew could travel and converse with Jews in distant places, just as priests and other educated Christians could converse in Latin. For example, Rabbi Avraham Danzig wrote
19380-423: The first in a series of Ofeq satellites and thus became one of only a few nations in the world possessing an indigenous space launching capability ( see timeline of first orbital launches by country ). The project management at Israel Aircraft Industries was headed for many years by Moshe Bar-Lev. The agency vision as defined by the guiding committee on July 27, 2005, states: "Space research and exploration
19550-528: The first satellite in the series, was launched on May 16, 1996, using a French-built vehicle. Since then, 4 more satellites were launched. The most recent AMOS satellite is the AMOS-5 which was launched on December 11, 2011. The AMOS is distinguished for its light weight and sophisticated technology. The AMOS-6 was due to be launched in 2016 in order to replace the AMOS-2 which was then ceasing operation, but it
19720-444: The further pollution of space and future issues with space debris. When satellites deorbit much of it is destroyed during re-entry into the atmosphere due to the heat. This introduces more material and pollutants into the atmosphere. There have been concerns expressed about the potential damage to the ozone layer and the possibility of increasing the earth's albedo , reducing warming but also resulting in accidental geoengineering of
19890-406: The generic term for these passages is Baraitot . The dialect of all these works is very similar to Mishnaic Hebrew. About a century after the publication of the Mishnah, Mishnaic Hebrew fell into disuse as a spoken language. By the third century CE, sages could no longer identify the Hebrew names of many plants mentioned in the Mishnah. Only a few sages, primarily in the southern regions, retained
20060-479: The geosynchronous orbit, getting a ‘ride’ as a secondary payload in the fairing of the rocket carrying a communications satellite. A joint American-Israeli proposal for this project was submitted to NASA by a team from Caltech/JPL ( Jet Propulsion Laboratory ), the Weizmann Institute of Science and Israel Aerospace Industries (IAI). The Israeli contribution will be funded by the Israel Space Agency and
20230-412: The impact of regulated ozone-depleting substances. Whilst emissions of water vapour are largely deemed as inert, H 2 O is the source gas for HO x and can also contribute to ozone loss through the formation of ice particles. Black carbon particles emitted by rockets can absorb solar radiation in the stratosphere and cause warming in the surrounding air which can then impact the circulatory dynamics of
20400-462: The impacts will be more critical than emissions in the troposphere. The stratosphere includes the ozone layer and pollutants emitted from rockets can contribute to ozone depletion in a number of ways. Radicals such as NO x , HO x , and ClO x deplete stratospheric O 3 through intermolecular reactions and can have huge impacts in trace amounts. However, it is currently understood that launch rates would need to increase by ten times to match
20570-403: The initial infrastructure required for space missions. The agency is currently headed by Chairperson Dan Blumberg and Director General Uri Oron [ he ] . Today, Israel is the smallest country with indigenous launch capabilities, as well as the smallest to have a space agency . Space research in Israel has history dating to the late 1950s. The Israeli Space Agency originated as
20740-462: The language as Ivrit , meaning Hebrew; however, Mishnah Megillah refers to the language as Ashurit , meaning Assyrian , which is derived from the name of the alphabet used , in contrast to Ivrit , meaning the Paleo-Hebrew alphabet . Hebrew ceased to be a regular spoken language sometime between 200 and 400 CE, as it declined in the aftermath of the unsuccessful Bar Kokhba revolt , which
20910-465: The language spoken by Jews in scenes from the New Testament) is often referred to as "Hebrew" in the text, although this term is often re-interpreted as referring to Aramaic instead and is rendered accordingly in recent translations. Nonetheless, these glosses can be interpreted as Hebrew as well. It has been argued that Hebrew, rather than Aramaic or Koine Greek, lay behind the composition of
21080-471: The language. The revival of the Hebrew language as a mother tongue was initiated in the late 19th century by the efforts of Ben-Yehuda. He joined the Jewish national movement and in 1881 immigrated to Palestine , then a part of the Ottoman Empire . Motivated by the surrounding ideals of renovation and rejection of the diaspora " shtetl " lifestyle, Ben-Yehuda set out to develop tools for making
21250-434: The late 1970s, the committee developed the infrastructure needed for research and development in space exploration and sciences. One of the NCSR's earliest achievements took place in 1961 with the launch of its first two-stage rocket. Following political tension with Egypt and Syria, reconnaissance flights became evermore difficult. In 1979, a satellite program was proposed followed by a year of feasibility study. The study
21420-744: The launch is scheduled for early 2026. The INSAT-1 and the INSAT-2 are two nano-satellites which were planned and developed by the Israeli Nano Satellite Association . Their purpose was to serve as a technology demonstrators. The INSAT-1 was set to carry a miniature atomic clock and a GPS receiver. By 2021, the mission was delayed and they were never launched. Hebrew language Hebrew ( Hebrew alphabet : עִבְרִית , ʿĪvrīt , pronounced [ ʔivˈʁit ] or [ ʕivˈrit ] ; Samaritan script : ࠏࠨࠁࠬࠓࠪࠉࠕ ʿÎbrit )
21590-543: The launching of that first satellite, Israel has developed into a significant player in the commercial space arena. Today, the ISA satellite launches include: After the successful launch of the Ofeq -1 in 1988, additional satellites were developed. In 1989, the ISA launched the Ofeq -2; in April 1995, it took a leap forward with the launch of Ofeq-3 , which carried an advanced electro-optical payload built by Israeli industry for local purposes. Ofeq-3 has been functioning without
21760-400: The mid-2000s, satellites have been hacked by militant organizations to broadcast propaganda and to pilfer classified information from military communication networks. For testing purposes, satellites in low earth orbit have been destroyed by ballistic missiles launched from the Earth. Russia , United States , China and India have demonstrated the ability to eliminate satellites. In 2007,
21930-725: The most potent scientific tools of the Twentieth Century." The United States had been considering launching orbital satellites since 1945 under the Bureau of Aeronautics of the United States Navy . Project RAND eventually released the report, but considered the satellite to be a tool for science, politics, and propaganda, rather than a potential military weapon. In 1946, American theoretical astrophysicist Lyman Spitzer proposed an orbiting space telescope . In February 1954, Project RAND released "Scientific Uses for
22100-727: The newly declared State of Israel . Hebrew is the most widely spoken language in Israel today. In the Modern Period, from the 19th century onward, the literary Hebrew tradition revived as the spoken language of modern Israel, called variously Israeli Hebrew , Modern Israeli Hebrew , Modern Hebrew , New Hebrew , Israeli Standard Hebrew , Standard Hebrew and so on. Israeli Hebrew exhibits some features of Sephardic Hebrew from its local Jerusalemite tradition but adapts it with numerous neologisms, borrowed terms (often technical) from European languages and adopted terms (often colloquial) from Arabic. The literary and narrative use of Hebrew
22270-557: The older satellites that reached the end of life , as a part of the regulatory process of obtaining a launch license. The largest artificial satellite ever is the International Space Station . By the early 2000s, and particularly after the advent of CubeSats and increased launches of microsats —frequently launched to the lower altitudes of low Earth orbit (LEO)—satellites began to more frequently be designed to get destroyed, or breakup and burnup entirely in
22440-534: The phonetic values are instead inspired by the acrophonic principle. The common ancestor of Hebrew and Phoenician is called Canaanite , and was the first to use a Semitic alphabet distinct from that of Egyptian. One ancient document is the famous Moabite Stone , written in the Moabite dialect; the Siloam inscription , found near Jerusalem , is an early example of Hebrew. Less ancient samples of Archaic Hebrew include
22610-550: The possible use of communications satellites for mass communications. He suggested that three geostationary satellites would provide coverage over the entire planet. In May 1946, the United States Air Force 's Project RAND released the Preliminary Design of an Experimental World-Circling Spaceship , which stated "A satellite vehicle with appropriate instrumentation can be expected to be one of
22780-591: The present day. It is perhaps the most important Hebrew manuscript in existence. During the Golden age of Jewish culture in Spain , important work was done by grammarians in explaining the grammar and vocabulary of Biblical Hebrew; much of this was based on the work of the grammarians of Classical Arabic . Important Hebrew grammarians were Judah ben David Hayyuj , Jonah ibn Janah , Abraham ibn Ezra and later (in Provence ), David Kimhi . A great deal of poetry
22950-570: The primary language of use, and to prevent large-scale incorporation of English words into the Hebrew vocabulary. The Academy of the Hebrew Language of the Hebrew University of Jerusalem currently invents about 2,000 new Hebrew words each year for modern words by finding an original Hebrew word that captures the meaning, as an alternative to incorporating more English words into Hebrew vocabulary. The Haifa municipality has banned officials from using English words in official documents, and
23120-412: The quantity of materials that are often left in the ocean. Rocket launches release numerous pollutants into every layer of the atmosphere, especially affecting the atmosphere above the tropopause where the byproducts of combustion can reside for extended periods. These pollutants can include black carbon , CO 2 , nitrogen oxides (NO x ), aluminium and water vapour , but the mix of pollutants
23290-674: The rest of the Middle East; and eventually Greek functioned as another international language with the eastern areas of the Roman Empire. William Schniedewind argues that after waning in the Persian period, the religious importance of Hebrew grew in the Hellenistic and Roman periods, and cites epigraphical evidence that Hebrew survived as a vernacular language – though both its grammar and its writing system had been substantially influenced by Aramaic. According to another summary, Greek
23460-427: 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. When an Earth observation satellite or a communications satellite
23630-409: The satellite; the slip rings can rotate to be perpendicular with the sunlight and generate the most power. All satellites with a solar panel must also have batteries , because sunlight is blocked inside the launch vehicle and at night. The most common types of batteries for satellites are lithium-ion , and in the past nickel–hydrogen . Earth observation satellites are designed to monitor and survey
23800-404: The satellites and receivers on the ground, combined with ever-improving electronics, allows satellite navigation systems to measure location to accuracies on the order of a few meters in real time. Astronomical satellites are satellites used for observation of distant planets, galaxies, and other outer space objects. Tether satellites are satellites that are connected to another satellite by
23970-538: The satellites stay still in the sky (relative to a fixed point on the ground). Some imaging satellites chose a Sun-synchronous orbit because they can scan the entire globe with similar lighting. As the number of satellites and space debris around Earth increases, the threat of collision has become more severe. A small number of satellites orbit other bodies (such as the Moon , Mars , and the Sun ) or many bodies at once (two for
24140-493: The southern villages of Judea." In other words, "in terms of dialect geography, at the time of the tannaim Palestine could be divided into the Aramaic-speaking regions of Galilee and Samaria and a smaller area, Judaea, in which Rabbinic Hebrew was used among the descendants of returning exiles." In addition, it has been surmised that Koine Greek was the primary vehicle of communication in coastal cities and among
24310-540: The space in 2021 to test the material's resilience to space conditions. Most satellites use chemical or ion propulsion to adjust or maintain their orbit , coupled with reaction wheels to control their three axis of rotation or attitude. Satellites close to Earth are affected the most by variations in the Earth's magnetic , gravitational field and the Sun's radiation pressure ; satellites that are further away are affected more by other bodies' gravitational field by
24480-434: The space research and exploration area." The main goals for vision realization are: ISA has signed cooperation agreements with the space agencies of: United States ( NASA ), France ( CNES ), Canada ( CSA ), India ( ISRO ), Italy ( ASI ), Germany ( DLR ), Ukraine ( NSAU ), Russia ( RKA ), Netherlands ( NIVR ) and Brazil ( AEB ). In 2010, the budget of the Israel Space Agency was increased to US $ 80 million to boost
24650-458: The special conditions of space could be useful for scientific experiments. The book described geostationary satellites (first put forward by Konstantin Tsiolkovsky ) and discussed the communication between them and the ground using radio, but fell short with the idea of using satellites for mass broadcasting and as telecommunications relays. In a 1945 Wireless World article, English science fiction writer Arthur C. Clarke described in detail
24820-474: The spoken language of the Russian Jews, should be treated as their only national language, while Hebrew was to be treated as a foreign language. Hebrew books and periodicals ceased to be published and were seized from the libraries, although liturgical texts were still published until the 1930s. Despite numerous protests, a policy of suppression of the teaching of Hebrew operated from the 1930s on. Later in
24990-459: The stratosphere. Both warming and changes in circulation can then cause depletion of the ozone layer. Several pollutants are released in the upper atmospheric layers during the orbital lifetime of LEO satellites. Orbital decay is caused by atmospheric drag and to keep the satellite in the correct orbit the platform occasionally needs repositioning. To do this nozzle-based systems use a chemical propellant to create thrust. In most cases hydrazine
25160-439: The system is critical for environmental and water related research, especially in light of the drastic global environmental changes and global warming. The Tel Aviv University Ultraviolet Explorer (TAUVEX) is a space telescope array conceived by Noah Brosch of Tel Aviv University . It was eventually designed and constructed for the university by El-Op. TAUVEX is a cluster of three bore-sighted 20-cm telescopes for observation in

It was due to be launched by India on board the ISRO satellite GSAT-4 satellite but due to a mis-match between the capabilities of the launched and the mass of the satellite, ISRO decided unilaterally to remove TAUVEX from GSAT-4. The telescope ended up in a limbo of constant delays. In 2012 ISA decided to terminate the TAUVEX project. The Gurwin TechSat
25840-580: The upper class of Jerusalem , while Aramaic was prevalent in the lower class of Jerusalem, but not in the surrounding countryside. After the suppression of the Bar Kokhba revolt in the 2nd century CE, Judaeans were forced to disperse. Many relocated to Galilee, so most remaining native speakers of Hebrew at that last stage would have been found in the north. Many scholars have pointed out that Hebrew continued to be used alongside Aramaic during Second Temple times, not only for religious purposes but also for nationalistic reasons, especially during revolts such as

26690-514: Was completed by late 1980; Saguy requested from prime minister Menachem Begin that the project proceed to its next phase. In 1982, a new recommendation called "Ofeq Program" was submitted for developing an observation satellite. The program included timelines, planning for a ground station, budget estimates, and personnel requirements. The primary goal was to develop a satellite program without relying on any foreign know-how, to allow flexibility and creativity. The launcher would be developed by Malam,
26860-463: Was destroyed in a launchpad explosion. The Earth Resources Observation Satellite (EROS) is a series of commercial observation satellites . The first satellite, the EROS A , was launched on December 5, 2000, from Svobodny Launch Complex using a Russian Start-1 . A second satellite, the EROS B , was launched on April 25, 2006. The EROS series are set to be launched once every 6 to 8 years. The EROS C
27030-657: Was developed in collaboration between the Dutch NLR labs , Fokker Space , and Rafael . The satellite is helped by the Israel Space Agency and the European Space Agency (ESA). The Israel Space Agency initiated the project and partly funded it by supplying the sub-propulsion system. The propulsion system, funded by the ISA, is fueled by cold gas and is constructed of four high-pressure canisters with pyrotechnic activation. The system can produce both linear acceleration and torque needed to perform slosh research. It
27200-438: Was nominated to be its Director-General. In 1982, the Israel Space Agency was created, which is responsible for coordinating the space program of Israel. The following year, the new head of military intelligence, Ehud Barak , suspended all work, and advocated the winding down of all projects, and planned to transfer the released financial resources to fulfill more priority tasks, he said. But his opinion did not become dominant in

27540-457: Was one of the world's first Microsatellites to be designed, built and launched by students. The satellite, developed by the Technion , was launched on July 10, 1998. The satellite was a great success, operating for over 11 years - setting a world record for the longest university satellite mission. The mission was completed in April 2010. The Sloshsat-FLEVO was a satellite launched for the study of liquid sloshing phenomena in space. The satellite
27710-566: Was published by Abraham Garton in Reggio ( Calabria , Italy) in 1475. With the rise of Zionism in the 19th century, the Hebrew language experienced a full-scale revival as a spoken and literary language.

The official ordinance stated that Yiddish, being
28220-426: Was the first academic treatise on the use of rocketry to launch spacecraft. He calculated the orbital speed required for a minimal orbit, and inferred that a multi-stage rocket fueled by liquid propellants could achieve this. Herman Potočnik explored the idea of using orbiting spacecraft for detailed peaceful and military observation of the ground in his 1928 book, The Problem of Space Travel . He described how
