Rum comes from the Indo-European *-ru = “open” → Germanic * ru-ma- = “open” → Old Norse rumr = “spacious” ( adjective ) → “space” ( noun ). Word was then only a description that said that something was open. Later it was used to describe the “it” that openness was in, then the space. Space is assumed to be a “something” which is open to anything else. The adjective spatial means ‘spatial’ or ‘for space’.

World space is the relatively empty regions of the universe minus stars and the planet with the dense part of their atmosphere . Often refers Mon simply as space , particularly in relation to space . An older, slightly more accurate term is outer space (the space outside the Earth and its atmosphere).
Philosophy
Immanuel Kant considered time and space as a priori forms of intuition. We can not recognize things-in-themselves, but only things as they appear to us. Phenomena, which recognizes appear physically in space and time, but the two are not even something physical.
They are a priori conception forms, ie. that they supersede any empirical cognition, because they simply represent the shape of our perception . Another way of saying it is that they are transcendental categories, ie. recognition conditions, ie they are necessary for recognition at all, but they can not even recognize hcg diet plan (But we’re talking about them, so our knowledge of them must be in a gray area).
Physics
In classical mechanics represents space the three-dimensional Euclidean space , in which objects may be located at three coordinates , usually represented by ( x , y , z ). In general relativity is room nothing in itself, but part of the four-dimensional spacetime .
Mathematics
In elementary geometry is the room also the usual three-dimensional Euclidean space . However, other geometric objects called compartments , and more abstract talk about such vector spaces and topological spaces . Several special cases of the latter have special names, such as Hilbert spaces .

The space is primarily a concept of geometry and physics , which means an extended abstract or otherwise, or the perception of this area. Conceptually, it is synonymous containing indeterminate edges.
But space takes many precise meaning and own multiple scientific disciplines derived from the geometry. The space then appears, in general, t shirt printing an All set-but structured: the area of work .
We still speak of space to designate a certain distance ( the space between two people ), a certain area ( the park covers a considerable space ) or a certain volume ( the closet occupies a large space ).
Summary
The word comes from Latin spatium, which has the same meaning as in French. In Old and Middle French, rather a space meant time, duration: the sun occupied the entire space of the day .
Geometry
The space is primarily a concept of geometry . For a long time (and still in pure geometry ), the Surveyor clung to conceptualize space (three dimensional) sensitive (that is to say the area of the astronomer ). This space has the basic components: the point , the right and the plan . He was first Euclidean until the invention of non-Euclidean geometries . In all cases, the Euclidean space retains a small-scale appearance.
Moreover, the analytic geometry introduced the notion of dimension of space, and developed a multi-dimensional geometry (finite dimensional and infinite).
Finally, modern geometry has been enriched by the topology and can now be fully qualified for space science .
Various disciplines derived from the geometry, as in physics as in mathematics, to give “their space” a more particular sense:
Physics
In physics , the notion of space (and how it is mathematically modeled) varies depending on experimental conditions:
In classical mechanics , whose laws explain almost all the phenomena occurring on a human scale, space is modeled as a Euclidean space of dimension 3.
The special relativity , whose laws take into account that the speed of light is constant regardless of the observer, introduced a link between space and time. The spacetime is modeled as a Minkowski space . These laws apply only in a limited (no acceleration of the repository, no gravity).
In general relativity , which extends the mechanical classical incorporating the fact that the speed of light by excluding the absolute nature of time is a constant, space, matter and time are related. The space-time is modeled mathematically as a variety of dimension 4, the curvature of which depends on the gravitational potential. The tangent space (approximation of the space over small distances and small times, ignoring the curvature) is a Minkowski space . The predictions of general relativity do not deviate significantly from predictions of classical mechanics to the extremely strong gravitational fields, or at extremely high speeds.
In quantum mechanics , which studies the phenomena at sizes so small that state changes are not continuous but are jump (quanta), the space is modeled as a Euclidean space of dimension 3, but the notion position no longer exists, and is replaced by the notion of wave function or probability cloud. Position and movement are linked by the Heisenberg uncertainty principle , which postulates that they can not simultaneously be known with precision, making impossible any notion of trajectory of a particle. Although effective in predicting the phenomena, this model poses problems of interpretation (eg School of Copenhagen ). For calculations, quantum mechanics does not consider the position of the studied system, but his condition. The states of the systems are modeled mathematically in a Hilbert space . In this area too, the movement (state changes) are discontinuous.
The physical space, or space-time , raises several questions philosophical :
Is space absolute or relative? In other words, as would happen if we pushed the entire universe of three meters in one direction? In physics, spacetime is relative, and a major theoretical result ( Noether’s theorem ) shows that explains the laws of conservation of momentum and of energy .
The space he has a geometry own or the geometry of space is it just a convention?
The question of the characteristics of the space had been approached by
Isaac Newton (space is absolute),
Gottfried Leibniz (space is relative)
Henri Poincare (the geometry of space is a convention)
Andy Godmiead (the will of spatial change is relative).
Mathematics
In mathematics , a space is a set equipped with additional structures remarkable, allowing them to define objects similar to those of the geometry usual. Items can be called as the context points , vectors , functions , … Here are some examples.
A topological space is a set with a very general structure (topology), which defines the notion of neighborhood of a point. This structure provides the language to define the notions of continuity and limits.
A metric space is a topological space whose topology is defined by a distance . The latter allows to estimate the size of a set ( diameter ), the proximity to a point, etc..
A uniform space is a topological space whose topology is defined by a set of finite differences (over a condition of separation). The uniform spaces include the topological groups .
A vector space is a set whose elements, vectors , can add up and be multiplied by scalars. On a given body, vector spaces are classified by their size , by definition the cardinal of any basis. An affine space is informally a vector space for which the position of the zero vector has been forgotten. This structure allows us to speak of linearity.
A set with both a vector space structure and a structure of topological space, compatible with each other in a certain sense, is called a topological vector space .
A normed vector space is a topological vector space in which one has a notion of length of a vector, a standard, making it especially a metric space. But certain metrizable topological vector spaces are provided without their topology can be defined by a standard.
A locally convex topological vector space is a topological vector space for which the topology is defined by a set of semi-standards.
A Minkowski space is a vector space of dimension 4, provided with an inner product (multiplication between vector), signature (+, -, -, -). This inner product defines the notion of orthogonality. Interpreted as a distance at a given point (although this is not a distance in the mathematical sense), this product separates the internal space into two parts: the space of points for which there is a distance, and space points ‘inaccessible’. Interpreted within the framework of special relativity, the space-time points (position, date) inaccessible are those that can not be achieved without exceeding the speed of light .
A symplectic vector space is a finite dimensional vector space, equipped with a bilinear form antisymmetric and nondegenerate.
In probability theory (but also in decision theory ), the space of elementary events is called the universe . That is, somehow, the workspace. The universe with a measure of a tribe as a probability space .
Theory of knowledge
See detailed article Theory of Knowledge .
Space is the form of our experience sensitive. This is an ideal, that is to say a structure of the mind , which contains our perceptions and where we locate the movement and body . In everyday experience, space is homogeneous, isotropic, continuous and unlimited.
We distinguish the psychological space and space mathematics . The psychological space can be divided into spaces visual, tactile, muscular, etc..
Bergson’s terminology
Henri Bergson defines the space in his works as all distances between points therein . This personal definition is challenged by Bertrand Russell who sees only a bad method for discovering properties certainly surprising, but that does not apply to space in our sense in everyday life to the word.
Space (physical)
For other uses of this term, see Space .
The physical space is the space where the objects and events that are occurring relative position and direction. 1 Physical space is usually designed with three -dimensional linear , although physicists usually consider it modern, with time , as part of a continuous infinite known as four-dimensional space-time , which in the presence of material is curved . In mathematics examines spaces with different numbers of dimensions and with different underlying structures. The concept of space is considered fundamental to an understanding of the universe even if continuous physical disagreement among philosophers about whether it is an entity, a relationship between entities, or part of a conceptual framework .
Many of these philosophical questions arose in the seventeenth century, Relevant Life Policy during the early development of classical mechanics . According to Isaac Newton , space was absolute in the sense that there was permanent and independent of matter. 2 In contrast, natural philosophers such as Gottfried Leibniz , thought the space was a collection of relationships between objects, given by its distance and direction from another. In the eighteenth century, Immanuel Kant described space and time as elements of a systematic framework which humans use to structure their experiences.
In the nineteenth and twentieth centuries mathematicians began to examine the non-Euclidean geometry , which can be said that space is curved rather than flat . According to the general theory of relativity of Albert Einstein space around gravitational fields deviates from Euclidean space . 3 Tests of general relativity have confirmed that non-Euclidean space provides a better model for the shape of space.

Philosophy of space
Leibniz and Newton
Gottfried Leibniz .
In the seventeenth century, the philosophy of space and time emerged as a central item in epistemology and metaphysics . At its heart, Gottfried Leibniz , German philosopher and mathematician, and Isaac Newton , English physicist and mathematician, developed two conflicting theories of what is space. Instead of being an entity that exists independently of and over the matter, Leibniz argued that space is nothing but a collection of spatial relationships between objects in the world: ” That Which is space results from places taken together “. 4 The unoccupied regions are those that could have objects in them, and so spatial relationships with other places. For Leibniz, however, space was an abstract idealized relations between individual entities or their possible locations and then would not be continuous but discrete . 5
The space might be thought similar to the relationships between family members. Although people of a family are related, relationships do not exist independently of people. 6 Leibniz argued that space could not exist independently of objects in the world because that would imply a difference between two universes exactly alike except for the location the material world in each universe. But there would be no way to distinguish between them because, under the principle of identity of indiscernibles , there would be no real difference between them. According to the principle of sufficient reason , any theory of space involving the possibility of these two universes, would be incorrect. 7
Isaac Newton .
Newton took space as more than relations between material objects and based their position on the observation and experimentation . For a relativistic may be no difference between inertial motion , in which the objects Chrome Wire Shelving travel at a speed constant, non-inertial motion , in which the velocity changes with time, since all spatial measurements are related to other objects and their movements. But Newton argued that since no motion generates inertial forces , it must be absolute. 8 He used the example of turning water into a bucket to prove his argument. The water in a bucket of a rope hanging position to turn, starting with a flat surface. After a time, as the hub is rotating, the surface becomes concave. If the rotation of the bucket is stopped, then the water surface remains concave as it continues to rotate. The concave surface, therefore, it is apparently the result of relative motion between the hub and water. 9 Instead, Newton said, must be the result of non-inertial motion in relation to the space itself. For several centuries the bucket argument was decisive to show that the space must exist independently of matter.
Kant
Immanuel Kant .
In the eighteenth century German philosopher Immanuel Kant developed the theory of knowledge in which knowledge about space can be both a priori and synthetic . 10 According to Kant, knowledge about space is synthetic , in that statements about the space are not simply true by virtue of the meaning of words in the statement. In his work, Kant rejected the view that space should be a substance or relationship. In contrast, concluded that space and time are not discovered by humans to be objective characteristics of the world, but are part of an unavoidable systematic framework for organizing our experiences. 11
Geometry Non-Euclidean
The spherical geometry is similar to the elliptical geometry . On the surface of a sphere no parallel lines .
The Elements of Euclid contain five principles that are the basis of Euclidean geometry. One of them, the parallel postulate has been debated among mathematicians for centuries. It postulates that in any plane on which there is a straight line L 1 and a point P outside it L 1 , there is only one straight line L 2 on the plane passing through the point P and parallel to L 1 . Until the nineteenth century, few doubted the veracity of this postulate, despite the debate centered on whether it was necessary as an axiom, or if it was a theory that could result from the other axioms. 12 Around 1830, the Hungarian János Bolyai and the Russian Nikolai Ivanovich Lobachevsky separately published treatises on a type of geometry that did not include the parallel postulate, called hyperbolic geometry . In this geometry, a number infinite parallel line passing through the point P . Consequently, the sum of the angles of a triangle is less than 180 or and the circumference of a circle in relation to its diameter is greater than pi . In the 1850s, Bernhard Riemann developed an equivalent theory called elliptic geometry in which parallel lines do not pass through P . In this geometry, the angles of more than 180 triangles or circles and have a ratio of circumference to diameter less than pi.
Geometry type Number of parallel Sum of angles in a triangle Ratio between the circumference and the diameter of a circle Measurement of curvature
Hyperbolic Infinite <180 or > Π <0
Euclidean 1 180 or π 0
Elliptical 0 > 180 or <Π > 0
Gauss and Poincare
Carl Friedrich Gauss .
Henri Poincare .
Although there was a prevailing Kantian consensus at the time, once the non-Euclidean geometries had been formalized, some began to wonder if the physical space is curved or not. Carl Friedrich Gauss , German mathematician, was the first to consider an investigation empirical geometrical structure of space. He thought a test of the sum of the angles of a triangle huge star and there are reports that actually conducted a test on a small scale, triangulating mountain tops in Germany. 13
Henri Poincare , French mathematician and physicist of the nineteenth century, introduced an important idea in which he attempted to demonstrate the futility of any attempt to find out what applies to space geometry by experiment. 14 In his view, scientists face a difficult situation if they are confined in the surface of a large imaginary sphere with particular properties, known as a sphere-world. In this world, the temperature usually varies in a way that all objects expand and contract at similar rates in different parts of the sphere. With proper temperature drop, if scientists try to use different yardsticks to determine the sum of the angles of a triangle, can be brought into thinking that inhabit a flat world, rather than a spherical surface. 15 In fact scientists can not determine, in principle, if they live in a flat or spherical world, said Poincaré, so does the debate over whether real space is Euclidean or not. For him, whose geometry was used to describe the space, was a matter of convention . 16 Since the Euclidean geometry is simpler than the non-Euclidean, assumed that the first always used to describe the “real” world geometry. 17
Einstein
Albert Einstein .
In 1905, Albert Einstein published a paper on a theory of special relativity , in which he proposed that space and time are combined into a single construct known as spacetime . In this theory, the speed of light in vacuum is the same for all observers, resulting in two events that appear simultaneous to an observer are not particular to another observer when both are in motion relative to one another- . Moreover, an observer will measure a moving clock run more slowly than a stationary with respect to them, and the measurements of objects tend to be reduced in the direction in which they are in motion relative to the observer.
In the next ten years Einstein worked in a general theory of relativity , which describes how gravity interacts with spacetime. Instead of viewing gravity as a force field acting in spacetime, Einstein suggested that it changes the geometric structure of it. 18 According to general theory, time slowly gear in places with lower gravitational potential and Light rays are deflected in the presence of a gravitational field. Scientists have studied the behavior of binary pulsars , confirming the predictions of Einstein’s theories and non-Euclidean geometry is usually used to describe the space-time.
Mathematics
In the mathematical modern mathematical spaces are defined as sets with some added structure. Often described as different kinds of strains , which are spaces that approximate the Euclidean space Phen375 , whose properties are defined largely by the local connection points found in each. However, there are many different mathematical objects that are called spaces. For example, the function spaces are generally not closely related to Euclidean space.
Geometry
The classical geometry was one of the first developments of mathematics that tried to capture and formalize the notion of physical space intuitva. Geometry probably originated in practical problems related to surveying .
Vector Spaces
A refinement of classical geometry was to define the existing economic structure of vector space from the particular properties of Euclidean space .
Physics
Classical Mechanics
Space is one of the few fundamental quantities of physics , in the sense that it can be defined through other fundamental physical quantities, not knowing anything more fundamental today. On the other hand, may be related to other fundamental quantities. Thus, like other fundamental quantities (like time and mass ), space can be explored through measurement and experiment.
Astronomy
Main article: Astronomy
The astronomy is the science related to the observation, analysis and measurement of objects in outer space .
Relativity
Main article: Theory of relativity
Before the work of Einstein in relativistic physics, space and time were viewed as independent dimensions. Einstein’s discoveries showed that they can be combined mathematically into an object called space-time . It turns out that the distances in space or in time separately are not invariant under the Lorentz transformation of coordinates, but distances in Minkowski space-time along space-time intervals, thus justifying the name .
In addition, time and space dimensions should not be seen as the exact equivalent in Minkowski spacetime. One can move freely in space but not in time. Thus, time and space coordinates are treated differently in special relativity (where time is sometimes considered a coordinate imaginary ) and general relativity (which are used for different spatial and temporal components of the metric the space-time ).
Furthermore, the theory of general relativity Einstein postulated that space-time is geometrically distorted ( curved ) near gravitationally significant masses. 19
Experiments are underway to attempt to directly measure gravitational waves . This is essentially solutions to the equations of general relativity, which describes the space-time waves in motion. This indirect evidence has been found the movement of binary systems Hulse-Taylor .
Cosmology
Main article: Shape of the Universe
The theory of relativity leads to the question cosmological what the shape of the universe and where it came from space. It seems that the space was created in the Big Bang and has expanded ever since. The general form of space is not known, it is known that space expanded very rapidly due to cosmic inflation . Alan Guth known for his theory of inflation, the first ideas presented at a seminar at the Stanford Linear Accelerator Center on 23 January 1980.
Measurement Space
Main article: Measurement
The measurement of physical space has been important for a long time. Although earlier societies had developed measuring systems, the International System of Units (SI), is now the most commonly used in the measurement of space, and is almost universally used within science .
Currently, the standard space interval, called a standard meter or simply meter , is defined as the distance traveled by light in vacuum during an interval of exactly 1/299792458 of a second. This definition, along with the current definition of the second , is based on the theory of special relativity in which the speed of light plays the role of a fundamental constant of nature.
Geography
The geography is the branch of science relating to the identification and description of the Earth , utilizing spatial awareness to try to understand why things exist in specific locations. The mapping is the assignment of spaces to allow better navigation, for visualization purposes and to act as a tracking device. Statistical concepts used geostatistics to spatial data collection in order to create an estimate of the observed phenomena.
The geographical area is commonly regarded as the land may be appropriate (in which case it is seen as property , plot or land ). While some cultures base their laws on private ownership of space, other approaches are identified with communal ownership of land, while some others, such as Australian Aborigines , rather than treat land as property, invert the relationship and are considered property of the land they inhabit.
Ownership of space is not restricted to land. Ownership of airspace and international waters is decided internationally. Other property have recently been established to other spaces, for example, frequency bands of radio of the electromagnetic spectrum or cyberspace .
The public space is the place where any person has the right to move, as opposed to private spaces, where the passage may be restricted, usually by criteria of private property , government or other reserve. Therefore, this space is public property , ownership and public use.
Psychology
The psychologists first began to study how we perceive the space in the middle of the nineteenth century. Everything about these studies is now a branch of psychology . Psychologists analyzing the perception of space in relation to how we recognize or perceive a physical object interactions.
Specialized studies include amodal perception and object permanence. The perception of surroundings is important due to its necessary relevance to survival, especially with regard to hunting and self-preservation and to the idea of personal space .
Found phobias related to space, including agoraphobia (fear of open spaces), the astrofobia (the fear of celestial space) and claustrophobia (fear of enclosed spaces).
The International Space Station ( ISS ) (in English , International Space Station or ISS ), also known as the International Space Station is a research center built in Denver Divorce Attorney Earth orbit. The project involves five space agencies: the NASA , the Russian Federal Space Agency , the Japan Aerospace Exploration Agency , the Canadian Space Agency and European Space Agency (ESA). 2 is considered one of the greatest achievements of the engineering .
The Brazilian Space Agency participates through a separate contract with NASA. The Italian Space Agency similarly has separate contracts for various activities not done within the framework of ESA’s work on the ISS (which involved Italy also fully).
The space station is located in orbit around the Earth at an altitude of approximately 360 kilometers, a type of low-Earth orbit. The actual height varies over time for several kilometers due to atmospheric drag and propulsion repeated. Make an orbit around the Earth in a period of about 92 minutes before June 2005 had completed over 37,500 orbits since the launch of the Zarya module on November 20, 1998.
In many ways the ISS represents a merger of previously planned space stations: the Mir-2 in Russia, the U.S. space station Freedom, the planned European Columbus module and the JEM (Japanese Experiment Module).
Thanks to the ISS, there is a permanent human presence in space, because there has always been at least two people aboard the ISS since the first permanent crew entered it on November 2, 2000. The station is maintained primarily by the launch today Russian Soyuz spacecraft and Progress , and in the past thanks to the Space Shuttle Americans until 2011, since the program space shuttle United States has been canceled before their exorbitant costs to help cut costs the U.S. government. The ISS is, as of August 2011 fully completed, and its recent construction work developed in 2010. In its early days, the station had a capacity for a crew of three astronauts , but since the arrival of the Expedition 20 , was ready to support a crew of six astronauts. Before the arrival of the German astronaut Thomas Reiter , the ESA , which joins the team of Expedition 13 in July 2006, all permanent astronauts belonged to the Russian space program, American or Canadian. The ISS, however, has been visited by astronauts from sixteen countries and was also the destination of the first six space tourists .

History
The International Space Station against the blackness of space and the thin line of the atmosphere of the Earth . Image taken from the Space Shuttle Discovery before the two spacecraft iniciasen separation.
The history of the ISS began on November 20, 1998, when the Russian rocket Proton placed in orbit on Russian module Zarya , the leading and largest model, designed Bankruptcy to equip the space station’s initial propulsion and power. Months later, NASA put in orbit by the Unity node of the space shuttle Endeavour . 3
Solar panels on the International Space Station.
On July 12, 2000 was added the second Russian service module Zvezda (pronounced / zviozda / ) which provided the life support systems of the Space Station and preparing the station to receive its first astronauts. On October 11, 2000 was added on the Unity node Z1 STI integrated structure enabling communication with the Earth . On November 2, arrive first crew aboard a Soyuz launched on October 31, 2000. A month after the first module was added which provided photovoltaic solar energy all season.
The following year came to the space station lab more importantly, the Destiny , American-made. It was docked at the station on February 7, 2001 by the shuttle Atlantis . On April 19, 2001 was placed on the first arm of the ISS, Canadian manufacturing. With the SSRMS arm also got a small Italian module and antenna UHF . On 12 July the same year he added a decompression chamber for the crew could leave the space station and take the first spacewalks. On 14 September 2001 added a Russian docking module with a decompression chamber.
On April 8, 2002 was coupled central segment of the future ITS S0 frame of 91 meters that will support large solar panels on the ends of the ISS. The Canadian SSRMS arm was placed in the Destiny module was transferred to the central segment S0 ITS on 5 June of that year. On October 7, was placed on the starboard ITS S1 segment of the frame of the station. The main frame was completed on November 23, 2002 with the STI port P1 segment.
On February 27, 2004, the crew Michael Foale and Alexander Kaleri conducted the first spacewalk involving the entire crew. Most of the objectives of the ride, including the installation of external equipment, were achieved before the mission was aborted due to a cooling problem in the HL Kalery suit.
On July 28, 2005 arrived at the station module load Italian Raffaello through the space shuttle Discovery from NASA.
On June 27, 2006 a piece of space junk that was later identified as the U.S. military satellite Hitch Hiker one released in 1963 and now out of service, spent about 2 kilometers from the ISS (it moves about 7.7 km / s). This event triggered an alarm and began preparations for an emergency evacuation of the space station. This approach was monitored by technicians CCVE Russian and the Center for NASA in Houston , and concluded without incident. It was felt that the piece of space junk had a mass of 79 kilos.
On July 7, 2006 the shuttle Discovery docked with the ISS successfully. Among the crew of Discovery was the German astronaut Thomas Reiter who along with American Jeff Williams and Russian Pavel Vinogradov are permanent crew of the orbiting complex. With the advent of astronaut ESA station moves from a permanent crew of two astronauts to three.
The International Space Station and Space Shuttle Discovery ready for mating.
On June 8, 2007, the shuttle Atlantis (mission STS-117 ) part to the International Space Station to install a new solar panels four task performed successfully. On day 10 detected a crack in the thermal cover shuttle Atlantis to be repaired in flight. 5 On day 14 there is a serious computer failure left without water, light and guidance capability to the space station. In the worst case, it should be evicted but the bug is fixed and return systems to normal operation. 6
On June 17, 2007 astronaut Sunita Williams becomes the woman who has been followed more time in space, completing 188 days and 4 hours away from our planet. 7
On October 23, 2007 delivered the Italian-made module Harmony and restructure part Container Store of preparing for future station assembly missions. 8 with a weight close to 16 tonnes and will serve as a gateway to European and Japanese laboratories.
In February 2008 he added the Columbus module and the European space shuttle Discovery in June again visited the ISS and added new components, which highlights the expected Kibo Science Laboratory.
On March 15, 2009 were added four sets of solar arrays to denver auto accident lawyer the station to accommodate more crew inside.

Robotic Arm
Canadarm 2
Main article: Canadarm 2
The Canadarm2 on the ISS.
The Canadarm2 is a manufacturing arm Canadian who also has an exceptional size and weight, unique features that put it far ahead of his older brother and the space shuttle. 32
It has 17.6 meters long (2.6 meters higher than the ferry) and is four times more light (1800 kg against 410). It is not really an arm but two that has a clever hand at each end. 33
The Canadarm2 may or may not have a base, as required, and it can be either hand. Each of these hands can hold some special steps to be placed in strategic points of the ISS and that will provide power, data and video connections. Grasping and letting go of these steps in coordination, as does a monkey to move from branch to branch, the robot will be able to move from one extreme to another and get to the ISS where it requires such delicate tasks as plug connectors, or as heavy as help engage the space shuttle.
Another of its virtues is brute force. The Canadarm2 is capable of handling volumes and rail cars up to 116 tons.
The new arm was released in June 2001, when the Atlantis brought the Quest airlock for spacewalks from the ISS, the Canadarm2 helped put the camera in place.
This is only the first part of the Mobile Servicing System on Space Station (SSRMS). The second part is the Mobile Base System, the size of a truck, will move on rails to bring the Canadian arm quickly from one extreme to another in the space station. The third and final part is the Special Purpose Manipulator Business. It is an intelligent hand equipped with lights, cameras and tools storeroom may install and replace batteries, power supplies and computers to delicate.
The Canadarm2 is controlled from the laboratory Destiny and the astronauts who operate it will be supported by two sub control on Earth, one in Houston (USA.) and one in Quebec (Canada), which are able to impart orders extras in case necessary.

The Soyuz TMA-6 approaching the International Space Station in 2005.
The U.S. space shuttle was in charge until July 2011, the station assembly and transport astronauts (seven) and heavy groceries to her.
Soyuz
Main article: Soyuz
The Soyuz was the ship that brought the first inhabitants of the ISS. He keeps the permanent crew of the space station carrying three astronauts. Serves as emergency ship if the ISS should be evacuated as each remains attached Soyuz an average of six months on the station. Since 2002, the Soyuz TMA using specially designed for the ISS. 36
Unmanned
The space agencies of Russia, Europe and Japan, through its unmanned supply ships will be responsible for transporting supplies to the station, apart from the Chicago Criminal Lawyer Space Shuttle. So far the Russians have been doing with the Progress vehicle, and in January 2008 it replaced the European ATV, much larger, which complemented the Japanese HTV in 2009. 37
Progress
Main article: Progress
Ship Progress M
The Russian Progress spacecraft are used to carry food and fuel to the ISS. Already been used with the Salyut 6, Salyut 7 and Mir. In addition to supplies and equipment, the Progress engines used on a regular basis to raise the orbit of the station. Its design is based on the Soyuz.
ATV
Main article: Automated Transfer Vehicle
Automated Transfer Vehicle for single use, is responsible for supplying the International Space Station (ISS) and evacuate the waste. The unmanned cargo vehicle Jules Verne, built by ESA, 38 was the first of these ships, which have a greater capacity than the Progress , 39 those used by the Russian Space Agency today. Their first release was made on 9 March 2008 in a rocket Ariane 5 40
HTV
Main article: Vehicle H-II Transfer
It is a contribution from the Japanese Space Agency to the international project. Transports water, supplies and experiments to the International Space Station. Although it is larger than the vessels need to be coupled Progress manually using the Canadarm2 because it has no automatic docking system. In its usual configuration the vehicle is broken into two sections: a pressurized port that connects to the nadir of Harmony, and a non-pressurized, usually for the transport of space exposure experiments for Kibo module.
Expedition to the ISS
The International Space Station is the most visited space infrastructure in the history of astronautics . To date 12 July 2006, has already had 153 visitors (not different). The MIR had 137 visitors (not different). The number of visitors than the ISS is 120.

Costs
The estimated total costs of the ISS is 100,000 U.S. dollars (USD) 41 Give an accurate cost assessment for the ISS is, however, very complicated, it is difficult to determine what costs should be added to the program really ISS or how the Russian contribution should be measured, since the Russian space agency works with USD considerably lower than the other partners.
NASA
In contrast to common belief, most of the costs of NASA not intended initially to build the ISS modules and external structure on land or for flight crew and supplies to the ISS. In fact, the space shuttle program, which as of 2006 cost about 5000 million dollars annually, usually not considered part of the ISS budget, but the shuttles were used almost exclusively for flights to the ISS since 1998.
The budget request for NASA to the government for 2007 lists the costs for the ISS (without Shuttle costs) and 25,600 million dollars from 1994 to 2005. 42 in 2005 and 2006 were assigned to the ISS between 1700 and 1800 million every year. This amount will rise in 2010, when projected to increase to 2300 million dollars and then must remain at the same level, at least until 2016 (date of scheduled completion).
The 1800 million dollars given in 2005 are distributed in: 43
Development of hardware new : only $ 70 million were allocated to major development in the first instance to the development of navigation systems, data carriers or life.
Space Shuttle Operations : $ 800 million, divided into 125 million for each sector: software, logistics and maintenance systems and extravehicular activities. Also additional 150 million are expended for flight avionics systems and crew. The remaining $ 250 million goes to the overall maintenance of the ISS.
Launch and mission operations : while the shuttle launch costs are not considered part of the ISS budget, mission integration (300 million), medical aid (25 million) and the shuttle launch site (125 million) are within the budget of the ISS.
Integration of program operations : $ 350 million were intended to maintain and sustain U.S. flight and ground hardware and software to ensure design integrity of the ISS and the continued safe operability of the orbital complex.
Supply and crew of the ISS : only $ 140 million were earmarked for the purchase of supplies, load capacity and flight crews for Progress and Soyuz craft.
NASA projections assume average costs of 2500 million from 2011 through 2016 and the end of the money allocated to the ISS in 2017 (300 to 500 million) after falling in 2016, the total costs of ISS project for NASA since the program’s inception in 1993 until its end will be about 53,000 million dollars. The 33 shuttle flights (which, as mentioned above, usually not considered part of the total costs of the ISS) for the construction and maintenance of the ISS will be about 35,000 million dollars. There have been considerable costs to design the Space Station Freedom in the 1980s and 1990s , before the ISS program that began in 1993. Therefore, although the actual costs contributed to the ISS are only half of the 100,000 million often cited in the media, if it meets the costs of the shuttle and precursor project design, reaching almost 100,000 million expenditure dollars, only for NASA.
FKA
A considerable part of the budget of the Russian Federal Space Agency is used for the ISS. Since 1998 there have been about two dozen flights of Soyuz and Progress spacecraft. Since the disaster of the Columbia has been commissioned to relieve the permanent crew and maintain the supply of the station from 2003 to 2006. The question of how long Russia can sustain the costs of the station is difficult to answer. The two Russian modules are currently in orbit derived from the MIR program and therefore development costs are much lower than for other modules also change between the ruble and the dollar is not properly displaying a true comparison of what the real costs to Russia.
The $ 20 million each space tourist paid for a seat on the Soyuz to the ISS is offset only a small part of the Russian financial contribution to the ISS.
ESA
The ESA estimates its contribution over the course of the project life (30 years) will be 8,000 million euros. 44 Costs for the Columbus laboratory now total more than 1000 million, the costs for development of totaling several ATV hundreds of millions and the added cost of each launch of Ariane 5 reaches around 125 million, each ATV launch also add significant costs.
JAXA
The Kibo laboratory has cost 2.8 billion dollars 45 according to a recent article this year. Besides the annual costs for Kibo laboratory will add about 350 to 400 million U.S. dollars. 46
CSA
Canada, whose contribution to the ISS is the Canadarm2 to the mobile support is estimated to last 20 years have contributed to about 1400 million Canadian dollars to the ISS 47
Space Tourism
Main article: Space Tourism
Since 2008, 6 tourists have visited the ISS, the payment is made by EE. States. , costs about $ 25 million. The tourists, or participants pay day loan Space were launched and returned through the rotation of the Russian crew Soyuz space missions. In addition, the ISS was the venue for the first wedding space in which the Russian cosmonaut Yuri Malenchenko, the Expedition 7 , married Ekaterina Dmitrieva, who was in Texas at that time. The last flight to the ISS space tourism took place in April 2009 . After that, the station will be upgraded to a permanent crew of 6, meaning that there will be seats available on the Soyuz and consequently there will be seating for Space Adventures , the company that runs the visits.

Incidents
On Thursday 12 March 2009 the PAM-D object 25 090 were on a collision course with the waste from the ISS, activating a contingency plan last minute due to the delay in detecting the event from Houston. As a precaution astronauts boarded the Russian capsule Soyuz , closing the respective gates and activating the automatic control of ISS. The Soyuz capsule remains constantly attached to the space station as a protective measure, the only means of escape in such cases. 48 On Friday, November 6, 2009 did a similar event with a smaller object to orbit but only 500 meters from the ISS. 49
