254-572: A Proton rocket on 20 November 1998. Zarya provided propulsion, attitude control , communications, and electrical power. Two weeks later on 4 December 1998, the American-made Unity was ferried aboard Space Shuttle Endeavour on STS-88 and joined with Zarya . Unity provided the connection between the Russian and US segments of the station and would provide ports to connect future modules and visiting spacecraft. While
381-690: A virtual reality exhibit called The Infinite featuring life aboard the ISS was announced. The International Space Station is a product of global collaboration, with its components manufactured across the world. The modules of the Russian Orbital Segment , including Zarya and Zvezda , were produced at the Khrunichev State Research and Production Space Center in Moscow. Zvezda was initially manufactured in 1985 as
508-475: A "shorter version" of MARS-500 may be carried out on the ISS. In 2009, noting the value of the partnership framework itself, Sergey Krasnov wrote, "When compared with partners acting separately, partners developing complementary abilities and resources could give us much more assurance of the success and safety of space exploration. The ISS is helping further advance near-Earth space exploration and realisation of prospective programmes of research and exploration of
635-495: A Q of 100 to be required for commercial fusion power stations to be viable. ITER will not produce electricity. Producing electricity from thermal sources is a well known process (used in many power stations) and ITER will not run with significant fusion power output continuously. Adding electricity production to ITER would raise the cost of the project and bring no value for experiments on the tokamak. The DEMO -class reactors that are planned to follow ITER are intended to demonstrate
762-427: A chemical reaction such as the burning of coal. It is the goal of a fusion power station to harness this energy to produce electricity. Activation energies (in most fusion systems this is the temperature required to initiate the reaction) for fusion are generally high because the protons in each nucleus strongly repel one another, as they each have the same positive charge . A heuristic for estimating reaction rates
889-777: A component for the Mir-2 space station, which was never launched. Much of the US Orbital Segment , including the Destiny and Unity modules, the Integrated Truss Structure , and solar arrays , were built at NASA's Marshall Space Flight Center in Huntsville, Alabama and Michoud Assembly Facility in New Orleans . These components underwent final assembly and processing for launch at
1016-480: A cryopump to cool the magnets to near absolute zero . High temperatures give the nuclei enough energy to overcome their electrostatic repulsion (see Maxwell–Boltzmann distribution ). For deuterium and tritium, the optimal reaction rates occur at temperatures higher than 10 kelvin. At ITER, the plasma will be heated to 150 million kelvin (about ten times the temperature at the core of the Sun ) by ohmic heating (running
1143-400: A current through the plasma). Additional heating is applied using neutral beam injection (which cross magnetic field lines without a net deflection and will not cause a large electromagnetic disruption) and radio frequency (RF) or microwave heating. At such high temperatures, particles have a large kinetic energy , and hence speed. If unconfined, the particles will rapidly escape, taking
1270-532: A distinct legal personality. The European Constitution was intended to consolidate all previous treaties and increase democratic accountability in them. The Euratom treaty had not been amended as the other treaties had, so the European Parliament had been granted few powers over it. However, the reason it had gone unamended was the same reason the Constitution left it to remain separate from
1397-554: A dozen Japanese universities conducted experiments in diverse fields. Cultural activities are another major objective of the ISS programme. Tetsuo Tanaka, the director of JAXA's Space Environment and Utilization Center, has said: "There is something about space that touches even people who are not interested in science."

ITER will use four types of magnets to contain the plasma: a central solenoid magnet, poloidal magnets around the edges of the tokamak, 18 D-shaped toroidal-field coils, and correction coils. A solid confinement vessel is also needed, both to shield
1651-599: A fusion reactor. My response was 'great idea', but from my position, I have no capability of pushing that idea upward to the President.' This push for cooperation on nuclear fusion is cited as a key moment of science diplomacy , but nonetheless a major bureaucratic fight erupted in the US government over the project. One argument against collaboration was that the Soviets would use it to steal US technology and expertise. A second
1778-425: A historic joint statement from Reagan and Gorbachev that emphasized, "the potential importance of the work aimed at utilizing controlled thermonuclear fusion for peaceful purposes and, in this connection, advocated the widest practicable development of international cooperation in obtaining this source of energy, which is essentially inexhaustible, for the benefit of all mankind." For the fusion community, this statement

On 21 November 2006, the seven project partners formally agreed to fund the creation of a nuclear fusion reactor. The program is anticipated to last for 30 years – 10 years for construction, and 20 years of operation. ITER was originally expected to cost approximately €5 billion. However, delays,
2286-401: A power station would be economical. Tests of such materials will be carried out both at ITER and at IFMIF (International Fusion Materials Irradiation Facility). Once fusion has begun, high-energy neutrons will radiate from the reactive regions of the plasma, crossing magnetic field lines easily due to charge neutrality (see neutron flux ). Since it is the neutrons that receive the majority of
2413-454: A propaganda campaign against Euratom, as it sought to stoke fears among Europeans that the organization would enable West Germany to develop nuclear weapons. The Common Assembly proposed extending the powers of the ECSC to cover other sources of energy. However, Jean Monnet , ECSC architect and President, wanted a separate community to cover nuclear power . Louis Armand was put in charge of
2540-659: A real power station; in ITER this electricity generating system is not of scientific interest, so instead the heat will be extracted and disposed of. EURATOM The European Atomic Energy Community ( EAEC or Euratom ) is an international organisation established by the Euratom Treaty on 25 March 1957 with the original purpose of creating a specialist market for nuclear power in Europe, by developing nuclear energy and distributing it to its member states while selling

#17327691930232794-492: A study into the prospects of nuclear energy use in Europe; his report concluded that further nuclear development was needed to fill the deficit left by the exhaustion of coal deposits and to reduce dependence on oil producers. However, the Benelux states and Germany were also keen on creating a general single market , although it was opposed by France due to its protectionism , and Jean Monnet thought it too large and difficult
2921-572: A task. In the end, Monnet proposed the creation of separate atomic energy and economic communities to reconcile both groups. The Intergovernmental Conference on the Common Market and Euratom at the Château of Val-Duchesse in 1956 drew up the essentials of the new treaties. Euratom would foster cooperation in the nuclear field, at the time a very popular area, and would, along with the EEC, share
3048-519: A third set of arrays were delivered on STS-116 , STS-117 , and STS-118 . As a result of the major expansion of the station's power-generating capabilities, more modules could be accommodated, and the US Harmony module and Columbus European laboratory were added. These were soon followed by the first two components of the Japanese Kibō laboratory. In March 2009, STS-119 completed

ESA offers
4318-412: Is near 85% complete toward first plasma. First plasma was scheduled for late 2025, however delays were acknowledged in 2023 which would impact this target. In July 2024, ITER announced a new schedule which included full plasma current in 2034, the start of operations with a deuterium-deuterium plasma in 2035, and deuterium-tritium operations in 2039. The start of the project can be traced back to 1978 when
4445-457: Is relatively abundant or can be produced in a fusion reactor. After preliminary tests with deuterium, ITER will use a mix of deuterium-tritium for its fusion because of the combination's high energy potential and because this fusion reaction is the easiest to run. The first isotope, deuterium , can be extracted from seawater , from which it is a nearly inexhaustible resource. The second isotope, tritium , only occurs in trace amounts in nature and
4572-450: Is that nuclei must be able to get within 100 femtometers (10 meter) of each other, where the nuclei are increasingly likely to undergo quantum tunneling past the electrostatic barrier and the turning point where the strong nuclear force and the electrostatic force are equally balanced, allowing them to fuse. In ITER, this distance of approach is made possible by high temperatures and magnetic confinement. ITER uses cooling equipment like

10033-405: The effects of long-term space exposure on the human body, including muscle atrophy , bone loss , and fluid shift. These data will be used to determine whether high duration human spaceflight and space colonisation are feasible. In 2006, data on bone loss and muscular atrophy suggested that there would be a significant risk of fractures and movement problems if astronauts landed on a planet after
10160-612: The end of World War II , sovereign European countries have entered into treaties and thereby co-operated and harmonised policies (or pooled sovereignty ) in an increasing number of areas, in the European integration project or the construction of Europe ( French : la construction européenne ). The following timeline outlines the legal inception of the European Union (EU)—the principal framework for this unification. The EU inherited many of its present responsibilities from
10287-587: The end of that year. When ITER becomes operational, it will be the largest magnetic confinement plasma physics experiment in use with a plasma volume of 840 cubic meters, surpassing the Joint European Torus by a factor of 8. On 3 July 2024, ITER director-general Pietro Barabaschi announced the first plasma production in the project will not take place until, at least, 2033. The energy from magnets will be produced no earlier than 2036, rather than 2033, as previously planned in 2016. He additionally said
10414-426: The energy with them, cooling the plasma to the point where net energy is no longer produced. A successful reactor would need to contain the particles in a small enough volume for a long enough time for much of the plasma to fuse. In ITER and many other magnetic confinement reactors, the plasma, a gas of charged particles, is confined using magnetic fields. A charged particle moving through a magnetic field experiences
10541-413: The energy, they will be ITER's primary source of energy output. Ideally, alpha particles will expend their energy in the plasma, further heating it. The inner wall of the containment vessel will have 440 blanket modules that are designed to slow and absorb neutrons in a reliable and efficient manner and therefore protect the steel structure and the superconducting toroidal field magnets. At later stages of
10668-403: The equivalent of 11 tonnes of coal. Nuclear fusion uses a different approach from traditional nuclear energy. Current nuclear power stations rely on nuclear fission with the nucleus of an atom being split to release energy. Nuclear fusion takes multiple nuclei and uses intense heat to fuse them together, a process that also releases energy. Nuclear fusion has many potential attractions. The fuel
10795-439: The estimated world's supply (mainly produced by the heavy-water CANDU fission reactors) is just 20 kilograms per year, insufficient for power plants. ITER will be testing tritium breeding blanket technology that would allow a future fusion reactor to create its own tritium and thus be self-sufficient. Furthermore, a fusion reactor would produce virtually no CO 2 emissions or atmospheric pollutants, there would be no chance of
10922-682: The evolution, development, growth and internal processes of plants and animals. In response to some of the data, NASA wants to investigate microgravity 's effects on the growth of three-dimensional, human-like tissues and the unusual protein crystals that can be formed in space. Investigating the physics of fluids in microgravity will provide better models of the behaviour of fluids. Because fluids can be almost completely combined in microgravity, physicists investigate fluids that do not mix well on Earth. Examining reactions that are slowed by low gravity and low temperatures will improve our understanding of superconductivity . The study of materials science
11049-431: The first crewed space flight around the Earth. By matching the orbit of the ISS to that of Vostok 1 as closely as possible, in terms of ground path and time of day, documentary filmmaker Christopher Riley and ESA astronaut Paolo Nespoli were able to film the view that Yuri Gagarin saw on his pioneering orbital space flight. This new footage was cut together with the original Vostok 1 mission audio recordings sourced from
11176-516: The head of the administrative body of ITER. In addition, it was agreed that 8% of the ITER construction budget would go to partner facilities that would be built in Japan. On 21 November 2006, at a ceremony hosted by French President Jacques Chirac at the Élysée Palace in Paris, an international consortium signed a formal agreement to build the reactor. Initial work to clear the site for construction began in Cadarache in March 2007 and, once this agreement
11303-648: The idea was further developed in November 1985 at the Geneva Summit with Ronald Reagan . Preparations for the Gorbachev-Reagan summit showed that there were no tangible agreements in the works for the summit. However, the ITER project was gaining momentum in political circles due to the quiet work being done by two physicists, the American scientist Alvin Trivelpiece who served as Director of
11430-445: The intense heat at the core fuses together nuclei and produces large amounts of energy in the form of heat and light. Harnessing fusion power in terrestrial conditions would provide sufficient energy to satisfy mounting demand, and to do so in a sustainable manner that has a relatively small impact on the environment. One gram of deuterium-tritium fuel mixture in the process of nuclear fusion produces 90,000-kilowatt hours of energy, or
11557-403: The magnets and other equipment from high temperatures and energetic photons and particles, and to maintain a near-vacuum for the plasma to populate. The containment vessel is subjected to a barrage of very energetic particles, where electrons, ions, photons, alpha particles, and neutrons constantly bombard it and degrade the structure. The material must be designed to endure this environment so that
11684-635: The most ambitious human collaborations since the development of the International Space Station (€100 billion or $ 150 billion budget) and the Large Hadron Collider (€7.5 billion budget). ITER's planned successor, the EUROfusion -led DEMO , is expected to be one of the first fusion reactors to produce electricity in an experimental environment. Fusion aims to replicate the process that takes place in stars where
11811-418: The most attractive for energy generation as they require the lowest activation energy (thus lowest temperature) to do so, while producing among the most energy per unit weight. All proto- and mid-life stars radiate enormous amounts of energy generated by fusion processes. Deuterium–tritium fusion releases, per mass, roughly three times as much energy as uranium-235 fission, and millions of times more energy than
11938-558: The net production of electricity. One of the primary ITER objectives is to achieve a state of " burning plasma ". Burning plasma is the state of the plasma when more than 50% of the energy received for plasma heating is received from fusion reactions (not from external sources). No fusion reactors had created a burning plasma until the competing NIF fusion project reached the milestone on 8 August 2021 using inertial confinement. At higher Q values, progressively bigger parts of plasma heating power will be produced by fusion reactions. This reduces
12065-608: The organizational structure and staffing, and the eventual location for the project. This meeting in Vienna was also where the project was baptized the International Thermonuclear Experimental Reactor, though it was quickly called by its abbreviation alone and its Latin meaning of 'the way'. Conceptual and engineering design phases were carried out under the auspices of the IAEA. The original technical objectives were established in 1992 and
12192-549: The original Engineering Design Activities (EDA) were completed in 1998. An acceptable, detailed design was validated in July 2001 to complete the extended EDA period, and the validated design then went through a Design Review that began November 2006 and concluded in December 2007. The design process was difficult with arguments over issues such as whether there should be circular cross sections for magnetic confinement or D-shaped cross sections. These issues were partly responsible for
12319-432: The plasma for short time periods; to demonstrate and test technologies that would be needed to operate a fusion power plant including cryogenics, heating, control and diagnostics systems, and remote maintenance; to achieve and learn from a burning plasma; to test tritium breeding ; and to demonstrate the safety of a fusion plant. ITER's thermonuclear fusion reactor will use over 300 MW of electrical power to cause
12446-438: The plasma to absorb 50 MW of thermal power, creating 500 MW of heat from fusion for periods of 400 to 600 seconds. This would mean a ten-fold gain of plasma heating power ( Q ), as measured by heating input to thermal output, or Q ≥ 10. As of 2022, the record for energy production using nuclear fusion is held by the National Ignition Facility reactor, which achieved a Q of 1.5 in December 2022. Beyond just heating
12573-404: The plasma volume of JT-60SA in Japan, the largest tokamak operating today. The long-term goal of fusion research is to generate electricity. ITER's stated purpose is scientific research, and technological demonstration of a large fusion reactor, without electricity generation. ITER's goals are to achieve enough fusion to produce 10 times as much thermal output power as thermal power absorbed by
12700-405: The plasma, the total electricity consumed by the reactor and facilities will range from 110 MW up to 620 MW peak for 30-second periods during plasma operation. As a research reactor, the heat energy generated will not be converted to electricity, but simply vented . ITER is funded and run by seven member parties: China , the European Union , India , Japan , Russia , South Korea and
12827-426: The power needed from external heating systems at high Q values. The bigger a tokamak is, the more fusion-reaction-produced energy is preserved for internal plasma heating (and the less external heating is required), which also improves its Q-value. This is how ITER plans for its tokamak reactor to scale. The initial international cooperation for a nuclear fusion project that was the foundation of ITER began in 1978 with
12954-574: The presence of other members of the ITER project. ITER is supervised by a governing body known as the ITER Council that is composed of representatives of the seven signatories to the ITER Agreement. The ITER Council is responsible for the overall direction of the organization and decides such issues as the budget. The ITER Council also appoints the director-general of the project. There have been five directors-general so far: Bernard Bigot
13081-418: The project has aims to: The objectives of the ITER project are not limited to creating the nuclear fusion device but are much broader, including building necessary technical, organizational, and logistical capabilities, skills, tools, supply chains, and culture enabling management of such megaprojects among participating countries, bootstrapping their local nuclear fusion industries. As of April 2022 ITER
13208-512: The rest of the EU: anti-nuclear sentiment among the European electorate, which may unnecessarily turn voters against the treaty. The Euratom treaty thus remains in force relatively unamended from its original signing. This overall timeline includes the establishment and development of Euratom, and shows that currently, it is the only former EC body that has not been incorporated into the EU. Since
13335-662: The rising costs or they would cancel the entire project outright. Simultaneously, the USSR was conducting planning for the Mir-2 space station, and had begun constructing modules for the new station by the mid-1980s. However the collapse of the Soviet Union required these plans to be greatly downscaled, and soon Mir-2 was in danger of never being launched at all. With both space station projects in jeopardy, American and Russian officials met and proposed they be combined. The ISS
13462-501: The rising price of raw materials, and changes to the initial design have seen the official budget estimate rise to between €18 billion and €20 billion. The reactor was expected to take 10 years to build, and ITER had planned to test its first plasma in 2020 and achieve full fusion by 2023. In 2024, ITER published a new schedule with deuterium-deuterium plasma operations starting in 2035. Site preparation has begun near Cadarache center, France, and French President Emmanuel Macron launched
13589-412: The routinely scheduled launches of resupply craft allows new hardware to be launched with relative ease. Crews fly expeditions of several months' duration, providing approximately 160 person-hours per week of labour with a crew of six. However, a considerable amount of crew time is taken up by station maintenance. Perhaps the most notable ISS experiment is the Alpha Magnetic Spectrometer (AMS), which
13716-420: The same launches and crew time. Research is conducted in a wide variety of fields, including astrobiology , astronomy , physical sciences , materials science , space weather , meteorology , and human research including space medicine and the life sciences . Scientists on Earth have timely access to the data and can suggest experimental modifications to the crew. If follow-on experiments are necessary,
13843-473: The space station. The ISS is expected to have additional modules (the Axiom Orbital Segment , for example) and will be in service until the end of 2030, after which it is planned to be de-orbited by a dedicated NASA spacecraft. As the space race drew to a close in the early 1970s, the US and USSR began to contemplate a variety of potential collaborations in outer space. This culminated in
13970-475: The station is divided into two sections: the Russian Orbital Segment (ROS) assembled by Roscosmos, and the US Orbital Segment (USOS), assembled by NASA, JAXA, ESA and CSA. A striking feature of the ISS is the Integrated Truss Structure , which connects the large solar panels and radiators to the pressurized modules. The pressurized modules are specialized for research, habitation, storage, spacecraft control, and airlock functions. Visiting spacecraft dock at
14097-404: The station via its eight docking and berthing ports . The ISS maintains an orbit with an average altitude of 400 kilometres (250 mi) and circles the Earth in roughly 93 minutes, completing 15.5 orbits per day. The ISS programme combines two prior plans to construct crewed Earth-orbiting stations: Space Station Freedom planned by the United States, and the Mir-2 station, planned by
14224-582: The station with Ku band communications, additional attitude control needed for the additional mass of the USOS, and additional solar arrays. Over the next two years, the station continued to expand. A Soyuz-U rocket delivered the Pirs docking compartment . The Space Shuttles Discovery , Atlantis , and Endeavour delivered the American Destiny laboratory and Quest airlock , in addition to
14351-554: The station's main robot arm, the Canadarm2 , and several more segments of the Integrated Truss Structure. Tragedy struck in 2003 with the loss of the Space Shuttle Columbia , which grounded the rest of the Shuttle fleet, halting construction of the ISS. Assembly resumed in 2006 with the arrival of STS-115 with Atlantis , which delivered the station's second set of solar arrays. Several more truss segments and
14478-517: The station, which was released on YouTube. It was the first music video filmed in space. In November 2017, while participating in Expedition 52 / 53 on the ISS, Paolo Nespoli made two recordings of his spoken voice (one in English and the other in his native Italian), for use on Misplaced Pages articles. These were the first content made in space specifically for Misplaced Pages. In November 2021,
14605-472: The station. The first crew, Expedition 1 , arrived that November aboard Soyuz TM-31 . The ISS grew steadily over the following years, with modules delivered by both Russian rockets and the Space Shuttle. Expedition 1 arrived midway between the Space Shuttle flights of missions STS-92 and STS-97 . These two flights each added segments of the station's Integrated Truss Structure , which provided
14732-514: The surplus to non-member states. However, over the years its scope has been considerably increased to cover a large variety of areas associated with nuclear power and ionising radiation as diverse as safeguarding of nuclear materials , radiation protection and construction of the International Fusion Reactor ITER . It is legally distinct from the European Union (EU) although it has the same membership , and
14859-509: The terms of the UK–EU Trade and Cooperation Agreement , the United Kingdom participates in Euratom as an associated state following the end of the transition period on 31 December 2020. The driving force behind the creation of Euratom was France's desire to develop nuclear energy and nuclear weapons without having to rely on the United States and/or the United Kingdom. The costs of nuclear development were also large, motivating France to share
14986-468: The tokamak began in 2020. The initial budget was close to €6 billion, but the total price of construction and operations is projected to be from €18 to €22 billion; other estimates place the total cost between $ 45 billion and $ 65 billion, though these figures are disputed by ITER. Regardless of the final cost, ITER has already been described as the most expensive science experiment of all time, the most complicated engineering project in human history, and one of
15113-522: The two countries jointly undertake the construction of a tokamak EPR as proposed by the INTOR Workshop. The ITER project was initiated in 1988. Ground was broken in 2007 and construction of the ITER tokamak complex started in 2013. Machine assembly was launched on 28 July 2020. The construction of the facility was expected to be completed in 2025 when commissioning of the reactor can commence and initial plasma experiments were scheduled to begin at
15240-852: The universe. Examples of Earth-viewing remote sensing experiments that have flown on the ISS are the Orbiting Carbon Observatory 3 , ISS-RapidScat , ECOSTRESS , the Global Ecosystem Dynamics Investigation , and the Cloud Aerosol Transport System . ISS-based astronomy telescopes and experiments include SOLAR , the Neutron Star Interior Composition Explorer , the Calorimetric Electron Telescope ,
15367-433: The withdrawal was made explicit. Withdrawal only became effective following negotiations on the terms of the exit, which lasted two years and ten months. A report by the House of Commons Business, Energy and Industrial Strategy Committee , published in May 2017, questioned the legal necessity of leaving Euratom and called for a temporary extension of membership to allow time for new arrangements to be made. In June 2017,
15494-531: Was a breakthrough, and it was reinforced when Reagan evoked the possibilities of nuclear fusion in a Joint Session of Congress later in the month. As a result, collaboration on an international fusion experiment began to move forward. In October 1986 at the Reykjavik Summit , the so-called 'Quadripartite Initiative Committee' (Europe through the Euratom countries, Japan, USSR, and the US) was formed to oversee
15621-455: Was appointed to reform the management and governance of the ITER project in 2015. In January 2019, the ITER Council voted unanimously to reappoint Bigot for a second five-year term. Bigot died on May 14, 2022, and his deputy Eisuke Tada took over leadership of ITER during the search process for the new director. ITER's stated mission is to demonstrate the feasibility of fusion power as a large-scale, carbon-free source of energy. More specifically,
15748-401: Was originally intended to be a laboratory, observatory, and factory while providing transportation, maintenance, and a low Earth orbit staging base for possible future missions to the Moon, Mars, and asteroids. However, not all of the uses envisioned in the initial memorandum of understanding between NASA and Roscosmos have been realised. In the 2010 United States National Space Policy ,
15875-550: Was ratified by all partners, the ITER Organization was officially established on 24 October 2007. In 2016, Australia became the first non-member partner of the project. ITER signed a technical cooperation agreement with the Australian Nuclear Science and Technology Organisation (ANSTO), granting this country access to research results of ITER in exchange for the construction of selected parts of
16002-461: Was symbolic and involved American criticism of how the Soviet physicist Andrei Sakharov was being treated. Sakharov was an early proponent of the peaceful use of nuclear technology and along with Igor Tamm he developed the idea for the tokamak that is at the heart of nuclear fusion research. However, Sakharov also supported broader civil liberties in the Soviet Union, and his activism earned him both
16129-550: Was the Skylab-Salyut Space Laboratory, which proposed docking the Skylab B to a Soviet Salyut space station. Falling budgets and rising Cold War tensions in the late 1970s saw these concepts fall by the wayside, along with another plan to have the Space Shuttle dock with a Salyut space station. In the early 1980s, NASA planned to launch a modular space station called Freedom as a counterpart to
