Introduction.

 In our work we are going to make a research work and to build our definitions of the space and other basic, background knowledge about space and explore possible motives that  make people

step in to the universe. We are going to see how people’s interest  to the space has been developing, what people made contributions in to the space development and how do we use the space.

Space definitions and terminology.

Now we are just like misunderstood dreamers, and we are to invent a wheel, a new one that will move us to a better understanding of the question studied. It’s not an easy task to give   a definition of the word that has been already given by the scientists, in different encyclopedias.

In our work we use different information recourses, that help us to create our own definitions.

They are Webster’s New World College Dictionary, Explanatory Dictionaries of the Russian Language, different books on astronomy and some Internet Recourses. These sources in total give us a  complete picture of the questions we search for.

Space – is the system with some cosmic objects in it. It is the expanse in which the solar system stars, and galaxies exist; the universe1. There are some types of space:

absolute space - physical space independent of what occupies it

phase space - (physics) an ideal space in which the coordinate dimensions represent the variables that are required to describe a system or substance; "a multidimensional phase space"

mathematical space, topological space - (mathematics) any set of points that satisfy a set of postulates of some kind; "assume that the topological space is finite dimensional"

outer space - any location outside the Earth's atmosphere; "the astronauts walked in outer space without a tether"

aerospace - the atmosphere and outer space considered as a whole

At all the word "space" has eight definitions, which are used in different field of science32.

Galaxy-huge groups of stars. Stars are found in huge groups called galaxies. Scientists estimate that the larger galaxies may contain as many as a trillion stars, while the smallest may have fewer than a million. Galaxies can be up to 100,000 light-years in diameter. 

            Galaxies may have any of four general shapes. Elliptical galaxies show little or no structure and vary from moderately flat to spherical in general shape. Spiral galaxies have a small, bright central region, or nucleus, and arms that come out of the nucleus and wind around, trailing off like a giant pinwheel. In barred spiral galaxies, the arms extend sideways in a short straight line before turning off into the spiral shape. Both kinds of spiral systems are flat. Irregular galaxies are usually rather small and have no particular shape or form.

            Like most stars, the sun belongs to a galaxy. Since the sun and Earth are embedded in the galaxy, it is difficult for us to obtain an overall view of the galaxy. In fact, what you can see of its structure is a faint band of stars called the Milky Way (the word galaxy comes from the Greek word for "milk"), so our galaxy has been named the Milky Way galaxy.

            The visible band of the Milky Way seems to form a great circle around Earth. This indicates that the galaxy is flat rather than spherical. (If it were spherical, the stars would not be especially concentrated in a single band.) The sun is located on the inner edge of a spiral arm. The center, or nucleus, of the galaxy is about 30,000 light-years distant, in the direction of the constellation Sagittarius. All the stars visible without a telescope belong to the Milky Way galaxy.

All the stars in the galaxy move in orbits around its center. The sun takes about 200 million years to complete an orbit. The orbits of most of these stars are nearly circles and are nearly in the same direction. This gives a sense of rotation to the galaxy as a whole, even as the entire galaxy moves through space. It is possible to calculate how much matter the galaxy must have in order to hold a star in its orbit by the force of gravity. In this way the approximate number of stars in the galaxy can be estimated.

According to the Doppler effect, a general relationship seems to exist throughout the universe: the greater the speed of a galaxy, the greater its distance. This relationship suggests that the system of galaxies is expanding. Suppose the galaxies were at one time in a rather small volume of space. After a time, the fast galaxies would have sped far from the original position, while the slow galaxies would still be nearby. The result would be a velocity-distance relationship exactly like the one observed.3

 

Universe-is the space with all planets in it. Cosmology is the scientific inquiry into what the universe is like. By making assumptions that are not contradicted by the behavior of the observable universe, scientists build models, or theories, that attempt to describe the universe as a whole, including its origin and its future. They use each model until something is found that contradicts it. Then the model must be modified or discarded.

 Since the universe appears to be expanding, it seems that it must have been smaller in the past. This is the basis for evolutionary theories of the universe. If one could trace the galaxies back in time, one would find a time at which they were all close together. Observations of the expansion rate indicate that this was between 10 and 20 billion years ago. Thus we have a picture of an evolving universe that started in some kind of explosion--the big bang. Some models of the universe predict that the expansion will continue forever. Others say that it will stop and be followed by a contraction back to a small volume again. Another model suggests that the universe oscillates, with alternate expansions and contractions. 

            Astronomers supporting the open universe theory believe that the universe will expand forever because they believe it is infinite. Supporters of the closed universe theory believe that at some time in the future the universe will stop expanding and will begin to contract until eventually a situation termed the "big crunch" would occur.3

Cosmos - the whole Universe considered as an ordered system5

Star-is a dead planet. People of the ancient world thought that stars were tiny lights on the inner side of a great, hollow globe. They made up stories about them and gave names to the patterns that they saw in the sky night after night and year after year (see Astrology; Constellation). Only with the birth of the modern science of astronomy did the true nature of the universe begin to reveal itself (see Astronomy).

Scientists still cannot say exactly what a star is. They do, however, know many facts about these myriad companions to the sun, which lights and warms the Earth.

Astronomers generally agree that most stars have approximately the same diameter as our sun. Some, however, are only one tenth its size; while others may be more than 100 times as large.

Stars are actually great globes of incandescent gases--their brightness depending upon their size and temperature. These glowing spheres are enormous powerhouses of atomic energy, and it is now believed that this energy is released by a process similar to the thermonuclear reaction that takes place in a hydrogen bomb explosion (see Nuclear Energy). The chemical content of a star is determined through the science that is known as astrophysics. In many stars the gases may be unbelievably thin, with the particles or atoms of matter in the gas far enough apart to make it a thousand times less dense than the air we breathe. Yet, for all its thinness, matter is there, perhaps a million times as much as we have in the Earth. Hydrogen, oxygen, and nitrogen are there, and perhaps iron, calcium, and other elements too. In cooler stars the matter may be more nearly liquid, more like the boiling iron in a blast furnace. In some old and comparatively cold stars, the matter may be packed so densely that a cubic inch of it would weigh a ton. Such stars are called dead or dark. 

Stars vary greatly in size and in color. They range from giant stars, which are much larger than the sun, to dwarf stars, which can be much smaller than the sun. In color they range from whitish blue stars with very high surface temperatures (more than 30,000 Kelvin, or 53,500o F) to relatively cool red stars (less than 3,500 K, or 5,840o F).

The star that we know best is our own sun. It is the center of our solar system, and the Earth revolves around it. The sun is only one among billions of stars. Likewise, our solar system is only a small segment of the great galaxy we call the Milky Way. Many other galaxies are visible through telescopes.3

Sun - a yellow dwarf star, a kind that is common in the Milky Way, and has a surface temperature of about 5,800 K (10,000o F). (The Kelvin temperature scale uses degrees of the same size as Celsius, or centigrade, degrees, but it is numbered from absolute zero, which is -273.15o C.) Although the sun is a rather ordinary star, it is very important to the inhabitants of the Earth. The sun is the source of virtually all of the Earth's energy. Yet the Earth receives only half a billionth of the energy that leaves the sun. Because the sun's energy is so intense, there are some real dangers in studying it. The intense heat of the sun's rays can destroy the retinal cells, causing blindness. For this reason, the sun should never be viewed directly. Furthermore, there is no safe way to view the sun through an ordinary telescope. Smoked glass and dark glasses give no protection from the great concentration of heat and light. The only safe way to study the sun is to project its image through a pinhole or a telescope onto a white screen.

            The average distance of the sun from the Earth, arbitrarily called one astronomical unit by astronomers, is 149,597,870 kilometers (92,958,350 miles). The sun's radius is about 432,500 miles, or 109.3 times the radius of the Earth, giving the sun a volume of about 1,306,000 times the volume of the Earth. It has been calculated that the sun's mass, or quantity of matter, is some 333,400 times as great as the Earth's mass.

A ray of light traveling from the sun at about 186,282 miles per second takes about 8 minutes 19 seconds to reach the Earth. Light from those other suns, the stars, takes much longer to reach the Earth. Light from the next nearest star, Alpha Centauri, takes more than four years to arrive, and light from the center of our galaxy, the Milky Way, takes many thousands of years. Because the sun is so near, it seems much larger than the other stars. They are visible on Earth only as bright points, even when viewed with the most powerful telescopes.3

Planet - the relatively large natural bodies that revolve in orbits around the sun, and presumably around other stars as well. The term does not include such smaller bodies as comets, meteors, and asteroids, many of which are little more than pieces of ice or rock.

The sun, the nine planets, their satellites, and all the smaller bodies, particles, and dust that circle the sun form the solar system. The sun, near the center of the solar system, governs the planets' orbital motions by gravitational attraction and provides the planets with light and heat. In order of increasing mean distance from the sun, the nine planets of the solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.

Mercury, Venus, Mars, Jupiter, and Saturn can be seen without a telescope. The ancient Greeks called them planetes, or "wanderers," because the objects appeared to move across the background of the apparently fixed stars. Although Uranus is also sometimes visible without a telescope, ancient astronomers were unable to distinguish it from the true stars.30,3

Meteor and meteorite - “object (usually not very big), which can fall down to the Earth from the space”. 2A flaming streak flashes across the night sky and disappears. On rare occasions the flash of light plunges toward Earth, producing a boom like the thundering of guns and causing a great explosion when it lands. When ancient peoples witnessed such displays, they believed they were seeing a star fall from the sky, and so they called the object a shooting star or a falling star. 

            Today these blazing trails of light are more fully understood. They are known to be caused by small chunks of stony or metallic matter from outer space that enter the Earth's atmosphere and vaporize. Before they encounter Earth's atmosphere, these chunks of matter are called meteoroids. Once they enter the atmosphere, they are called meteors. Most meteors never reach Earth--they are so tiny that they vaporize completely soon after entering the atmosphere. Sometimes the particles are large enough, however, that they remain partly intact. The large, dense objects that survive the fall to Earth are called meteorites. Although thousands of meteoroids enter the atmosphere each year, it is estimated that only about 500 actually reach the ground before vaporizing.3

Constellation. In three-dimensional space, most of the stars we see have little relation to one another, but can appear to be grouped on the celestial sphere of the night sky. Humans excel at finding patterns and throughout history have grouped stars that appear close to one another into constellations. The sky is currently divided into 88 Constellations. Constellations usually nave names (usually from mythology). Astronomers use constellations to designate directions in space; for example the great galaxy "in Andromeda" lies in the direction from us marked by the pattern of stars we call Andromeda (the Princess of Ethiopia in Greek mythology).24

Some constellations can be seen only from the Northern Hemisphere and some only from the Southern Hemisphere. The constellations of the Zodiac can be seen from both hemispheres.

Some constellations can be seen only from the Northern Hemisphere and some only from the Southern Hemisphere. The constellations of the Zodiac can be seen from both hemispheres.3

Comet-   a small object in space that moves round the Sun and has a bright head and a long tail.People now look forward with interest to sighting a comet, but for many centuries comets were believed to have an evil influence on human affairs; in particular, they were thought to foretell plagues, wars, and death. It was once thought that comets were made of vapor and had risen from the Earth. It was not until the 17th century that they began to be properly understood. In 1682 a comet appeared and was observed by the astronomer Edmond Halley. He studied the written accounts of 24 comets that had been seen from time to time since 1337 and calculated their orbits. He found that the comets of 1531, 1607, and 1682 moved in almost the same paths, and he concluded they were all the same one and that it would return in about 1758.

 

Orbit - The closed path of a satellite about a primary; a complete trip of a satellite about its primary; the act of placing a satellite into orbit.

Spacecraft - a vehicle designed for flight beyond the Earth's atmosphere.

Space capsule – “a vehicle which may carry people or animals, and travels into space to obtain information and then comes back to the Earth.”

Space station – a large space-craft that are in space for a long time and act as a base for scientific tests, etc.

Space shuttle – “a vehicle for carrying people and supplies between the Earth and a space station; carrying people into space to do scientific experiments, put satellites into space, etc.”

Space-craft – “a vehicle able to travel in space.”

Satellite - a body that is in orbit around a primary.

Micro satellites – a small craft that track and follow other satellites. This technology could prove useful for military (anti - satellites) missions if it were able to maneuver close enough to the target to disrupt or destroy it.

Rocket “a tube-shaped object that is driven to the air by burning gases and is used for traveling into space.” Rockets can be used as a weapon.

Rocket launcher – “a machine, carried by hand or on a vehicle, for sending up military rocket-type bombs.”

Astronaut - a United States spacecraft pilot or crewman.

Cosmonaut - a Soviet spacecraft pilot or crewman.

Space Weapons - damage causing mechanisms actually based in space. 4

Weaponisation- It is the use of the arms in space  in order to destroy something. It’s a general term that is used to characterize activities that countries have undertaken for nearly 60 years.9

Militarisation is a process of improving intelligence and military operations in order to strengthen the powerful abilities of the objects.

Anti-satellite weapon - any device specifically designed to destroy a satellite or interfere with its functioning (even can be based on the Earth).

Space commercialization– a program refers to the use of space for commercial purposes. Current examples of this activity are satellite communications: television and radio, GPS (Global Positioning System), satellite navigation. It also includes human activities in space such as space tourism, satellite manufacturing, micro-gravity science, and research and development.

Space debris - all man-made objects in Earth orbit, including their fragments and parts, which are non-functional or destroyed.

 

 

 

The history of astronomy or how the peoples’ interest to space has been developing

In this part of our work we want to dwell upon the history of astronomy to show how great peoples’ interest to the space, and how it developed was. The space era began not so many years ago, but a great number of people had been interested in space since the earliest times. As witnesses of this there is Stonehenge in England and Arkaim in the Chelyabinsk Oblast, in Russia.They are the ancient proofs of the man’s existence and of the development of the ancient science and peoples’ interest to the space. They are silent witnesses of the changes that   had been happening before the book was invented.

From the earliest times people were interested in space because they didn’t know anything about it and thought that their Gods lived there. It was something mysterious and beyond their understanding.

 Later on space and the stars, especially, were used to predict weather, even the future.

Then people as they usually did tried to use space as the source of some natural recourses and that was the beginning of civilian use if the universe. Just together with it military man understood all the advantages of using space. But we’ll discuss this question a little bit later.

 

·          5000 BC: Mesopotamian civilization

In many early civilizations, astronomy was sufficiently advanced that reliable calendars had been developed. In ancient Egypt astronomer-priests were responsible for anticipating the season of the annual flooding of the Nile River. The Mayas of the Yucatan peninsula developed a complicated calendar for keeping track of days both in the past and in the future. They could use their calendar to predict astronomical events.3

 

·    2500 BC and 2000 BC: England

Stonehenge is a Neolithic and Bronze Age megalithic monument located near Amesbury in the English county of Wiltshire, about 8 miles (13 km) north of Salisbury. It is composed of earthworks surrounding a circular setting of large standing stones and is one of the most famous prehistoric sites in the world. The Neolithic observatory at Stonehenge allowed for observation of 15 astronomical phenomena using 22 elements. The precision of measurements in Stonehenge is estimated at 10 arc-minutes to a degree.

 In 2006 the anthropologist Lionel Sims published in the "Cambridge Archaeology Journal" arguing that the Stonehenge double alignment on the southern standstill moonsets and the winter solstice sunsets was true of hundreds of prehistoric monuments, and was part of an emerging solar religion that both preserved and displaced a more ancient respect for the moon.16

 

·    14th century BC: China

In China, a calendar had been developed by the 14th century BC. A Chinese astronomer, Shih Shen, drew up what may be the earliest star catalog, listing about 800 stars. Chinese records mention comets, meteors, large sunspots, and novas.3

 

·    17th century BC: the Southern Urals steppe

Arkaim is an archaeological site situated in the Southern Urals steppe, 8.2 km north-to-northwest of Amurskiy, and 2.3 km south-to-southeast of Alexandronvskiy, two villages in the Chelyabinsk Oblast, Russia, just to the north from the Kazakhstani border.

The site is generally dated to the 17th century BC. Earlier dates, up to the 20th century BC, have been proposed. It was a settlement of the Sintashta-Petrovka culture, associated with Indo-Iranians (citation needed).

The similarity of latitude, date, and size led some archaeoastronomists (Bystrushkin 2003) to compare Arkaim with Stonehenge in England. The contemporaneous observatory at Arkaim allowed for observation of 18 astronomical phenomena using 30 elements. The precision of measurements in Arkaim is estimated at 1 arc-minute to a degree. The interpretation as an observatory for either Stonehenge or Arkaim is not universally accepted.12

 

·    276?-194 BC: Greece

The early Greek astronomers knew many of the geometrical relationships of the heavenly bodies. Some, including Aristotle, thought Earth was a sphere. Eratosthenes, born in about 276 BC, demonstrated its circumference. Hipparchus, who lived around 140 BC, was a prolific and talented astronomer. Among many other accomplishments, he classified stars according to apparent brightness, estimated the size and distance of the moon, found a way to predict eclipses, and calculated the length of the year to within 6 1/2 minutes.3

 

·    AD 127: Greece

The most influential ancient astronomer historically was Ptolemy (Claudius Ptolemaeus) of Alexandria, who lived in about 140 AD. His geometric scheme predicted the motions of the planets. In his view, Earth occupied the center of the universe. His theory approximating the true motions of the celestial bodies was held steadfastly through the fall of Rome to the end of the Middle Ages.

   In medieval times Western astronomy did not progress. During those centuries Hindu and Arabian astronomers kept the science alive. The records of the Arabian astronomers and their translations of Greek astronomical treatises were the foundation of the later upsurge in Western astronomy.

Almagest is the Latin form of the Arabic name (al-kitabu-l-mijisti, i.e. "The Great Book") of a mathematical and astronomical treatise proposing the complex motions of the stars and planetary paths, originally written in Greek as "Mathematical Treatise", later titled "The Great Treatise" by Ptolemy of Alexandria, Egypt. The date of Almagest has recently been more precisely established. Ptolemy set up a public inscription at Canopus in Egypt in 147/148 C.E.

Hence Almagest cannot have been completed before about C.E. 150, a quarter century after Ptolemy began observing. Its geocentric model was accepted as correct for over a thousand years in Arab and European societies. The Almagest is our most important source of information on ancient Greek astronomy3

·    1st millennium of the Christian era: Maya

The Dresden Codex, written by the Maya during the 1st millennium of the Christian era, contains astronomical calculations--eclipse-prediction tables, the synodic period of Venus--of exceptional accuracy. Temples and pyramids in what are now Mexico and Guatemala were often constructed and aligned with attention to astronomical phenomena.3

 

·    1543: Poland and Italy

   In 1543, the year of his death, came the publication of Copernicus' theory that Earth and the other planets revolved around the sun. His suggestion contradicted all the authorities of the time and caused great controversy. Galileo supported Copernicus' theory with his observations that other celestial bodies, the satellites of Jupiter, clearly did not circle Earth.14,6

 

·    1546-1601: Danmark(Brahe Tycho)

Danish astronomer; created new epoch in astronomy by improvements in astronomical observation

   The great Danish astronomer Tycho Brahe rejected Copernicus' theory. Yet his data on planetary positions were later used to support that theory. When Tycho died, his assistant, Johannes Kepler, analyzed Tycho's data and developed the laws of planetary motion. In 1687, Newton's law of gravitation and laws of motion reinforced Kepler's laws15.

 

·    1634: Germany

'Sleep', a moon-trip fantasy by German astronomer Johannes Kepler, is published.15

 

·    1800

The development of the spectroscope in the early 1800s was a major step forward in the development of astronomical instruments. Later, photography became an invaluable aid to astronomers. They could study photographs at leisure and make microscopic measurements on them. Even more recent instrumental developments--radar, the radio telescope, and space probes and manned spaceflights--have helped answer old questions and have opened our eyes to new problems.

 

We can see that the interest in space began its development already in 5000 BC. People from all parts of the world tried to research expanses of universe. A lot of countries contributed their share in  the development of astronomy: England, China, Russia, Egypt, Greece, Poland, Italy, Denmark, Germany and others. And after the knowledge was enough the first man stepped in to space.

 

 

 

 

 

 

The History of Man in Space

From Dream to Reality

Before the XVIIIth century people only observed the space with telescopes, calculated distances between planets, some facts they knew and could explain but others they simply thought out. Since the XVIIIth  century  man  tried to use stored knowledge, did some broadcasts, so did all to fly into space. Their notions and real knowledge were mirrored in books: scientific and fiction. While on the subject of fiction books a lot of authors tried to predict the future. And sometimes their notions were realized in future. The new science, which is called astronautics, appeared.

We researched how people’s interest in space has been developing. So we can see that since ancient times a man has been attracted by expanses of universe. With the coming of astronautic era the dream of leaving the Earth became the reality. With the little step on the Moon's surface mankind did a very big jerk in the future. And of course  sometimes fiction was realized some predictions became true. Here we want to analyze Jules Verne’s classic novel 'From the Earth to the Moon'. It produced a kind of a boom at his times.

 

Jules Verne's''Round the Moon''-Facts and Fiction

1. Jules Verne supposed that people in spaceships could eat usual food

Because of zero gravity they could not eat usual food in the projectile at all.

Weightlessness is the experience (by people and objects) during freefall, of having no apparent weight. This condition is also known as microgravity. Weightlessness in common spacecrafts is not due to an increased distance to the earth; the acceleration due to gravity at an altitude of, say, 100 km is only 3% less than at the surface of the earth.18

If the astronauts tried to eat their usual food, their food would fly in the spaceship.

Jules Vern was mistaken about the behavior of the substances in the space. Today they use the method of sublimation to keep the food fresh - the change from solid to gas without passing the liquid state.17

2.The author didn’t have any notions about the behavior of airless space and he did not surmise about the difference of the pressure in the space and in the projectile.

Pressure is everywhere.Outer space is a very hostile place. Because of the very low pressure in outer space humans have to be trapped in a spacesuit in fear of the boiling of their bodily liquids. The fluids would not be able to evaporate entirely primarily because of the rapid loss of heat energy.

In outer space one would also face extreme changes in temperature. The temperature in the sunlight is 120 °C, which is higher than the boiling point of water. In the shade the temperature is about -100 °C, way below the freezing point of water. The body tissue (skin, heart, other internal organs) would expand because of the boiling fluids7.

If they opened the hatch, the air would leave the projectile immediately, and people would be frozen.

Nowadays,  the scientists worked out the atomic plant for the utilization in spaceships. The rubbish is put in to the special module and when the plant goes through the atmosphere, the module is burned down with the rubbish.

 

 

3.Jules Verne believed that the temperature in the outer space was 70-80 degrees Fahr. below zero.

-70 degrees Fahrenheit = -57 degrees Celsius22

According to Vern, the space temperature was close  to the Moon’s temperature. The Moon's temperature in the sunlight is 120 degrees Celsius and in the shade the temperature is about -100 °C. The first measuring of the Moon`s temperature was in 1915 by Petitt18

 

4.Verne described the very strange occurrence of oxygen poisoning.

Jules Verne described the real event, hyperoxia (O2 supersaturation or "Paul Bert effect") by name.

 

Hyperoxia -

1. An excess of oxygen in tissues and organs.

2. A higher than normal oxygen tension, such as that produced by breathing air or oxygen at greater than atmospheric pressures20.

But this event was described and proved  only in 1878 by French physiologist and politician Paul Bert/19

 

5.The author believed that on the moon there were no twilights and night changed day promptly.

 

1.     There are twilights on the Moon. They are just like solar ones, but much colorless.

 

2.     212 degrees Fahrenheit = 100 deg. Celsius22

The first measuring of The Moon`s temperature was made in 1915  by Petitt:

at the afternoon: 125 deg. Celsius

at the midday: -175 deg. Celsius9

 

6.Jules Verne described the lunar night that lasted, in his opinion, 354 hours.

The real continuance of the Moon's night is 327,8604 hours. 21

Some coincidences.

 The projectile took off peninsula Florida, where a century later the first space to the moon "Apollo-8", started also with three astronauts on board (21.12.1968). It was the first spaceship, which flew round the Moon.26,10

The projectile was the same size as "Apollo-11" did. (16.07.1969). see the pictures.27

After the flight to the Moon Jules Verne's projectile touched down in the Pacific Ocean, only 3 miles from the place, where in 1969 the American spaceship "Apollo-11" with Armstrong Neil Alden, the first men on the Moon touched down. 28Some research workers are sure these couldn’t be only the coincidences.

               

 “Apollo-11.”11                                                                                 Verne’s picture.

 

 

Jules Verne really predicted some great phenomena in his book ''Round the Moon'': the missile principle of moving, the Moon's temperature, "Paul Bert effect" and the continuance of the Moon's night. But some his notions were wrong: the travelers must have died; he was wrong with the behavior of airless space, space food, the Moon's twilights, rubbish in space, and Moon's attractive power.

 And what all the scientists would do without the astronauts.

 

Some Notable Astronauts and Cosmonauts

There are few among us that did not wonder in awe about what it would be like to be an astronaut in a child. Space exploration will forever peak humanity’s interest and curiosity. The prestige of visiting outer space belongs to a proud few, but as technology develops, more and more people will have the opportunity.

The Federation Aeronautique International states that a man or a woman officially becomes an astronaut upon reaching an altitude of over 100 miles. As of March 30, 2006, 443 people have crossed this imaginary line. Efforts to learn more about space are widespread. Since the astronaut Yuri Gagarin made his pioneering exit out of our atmosphere, men and women from 35 countries have joined his notoriety.

Since the infancy of human presence in space, 18 astronauts have died on missions, and 10 more from launches. Despite this, our interests remain strong and our minds stay determined. We found out more about outstanding astronauts and their roles in the development of space.

The Use of Space. Civilian or Commercial and Military.

Nowadays people use space with maturity in two ways: military or civilian (economic/commercial, scientific etc.). Every day scientists find new ways of using the space. Every year more and more countries want to explore and use the space: not only the USA and Russia, but China, the European Union (ESA and some individual member states), Japan, India, Ukraine and Israel.

As space technology progressed after World War II, a curious development occurred. From the research that produced the rocket motors, liquid propellants, space suits, and other necessities of space flight emerged by-products that no one had anticipated. These were unexpected applications--in medicine, industry, and the home--for materials, equipment, and services that had been created for use in space. Such by-products are called spin-offs or fallout. Only a few of hundreds can be named here. 

Boons to Medicine

Perhaps the best-known examples of spin-offs are found in hospitals and doctors' offices. Some of these stem from space medical research. Many are adaptations from other areas of space technology. Typical of spun-off implements is a sight switch that permits some disabled people to operate devices they could not otherwise use. They do this by using their eye movements to interrupt a light beam.

   Another device, which was developed to enable astronauts to steer spacecraft by voice command, can be used to help the retarded learn to speak, the deaf to speak more clearly. The device permits users to compare the oscilloscope trace of their voices with a trace of the desired sound. 

   Microminiature electronic components--required because spacecraft devices must be small and light and use little power, yet be very rugged and durable over a relatively long period of time--have made many instruments available to doctors and their patients.

There are now hearing aids, not much larger than aspirin tablets, that are worn entirely within the ear.

 A television camera the size of a cigarette package is mounted on the surgeon's head to give students a close-up view of an operation. Other small cameras, equipped with flexible light-transmitting devices, take pictures inside such body organs as the stomach. 

   Biotelemetry, which was developed to monitor the temperature, brain-wave activity, breathing rate, and heartbeat of astronauts, offers a new means of monitoring hospital patients.

Biosensors attached to the body send data by wire or radio. This information may be displayed on oscilloscopes for doctors to analyze. It can also be fed into a computer that "watches" the patient and sounds an alarm if the results indicate that he requires medical assistance. Some biosensors, called endoradiosondes, can be implanted in the body. The tiny batteries that power them can be recharged by radio waves. 

   The search for a better insulating material for rocket- propellant tanks produced a plastic polymer gel with the density of human fat at body temperature. Used as a padding for bedridden patients, it prevents bedsores. Aerospace scientists in England developed a special bed which enables burn patients literally to float on a cushion of air. The burns heal more quickly because they do not rub against bedclothes. 

   The scientists who developed the Surveyor lunar probe found that they could make the pictures that the Surveyor was designed to photograph clearer by using a specially-designed computer to control printing. This technique, when applied to X-ray pictures taken in various fields of medicine, reveals anatomical details that were previously invisible with conventional X-ray technology. 

   The requirement for small, accurate, and rugged timing devices in spacecraft led to the development of a very small tuning fork that vibrates at 360 cycles per second, some 144 times as fast as the balance wheel in a conventional watch. The device is now a component of highly accurate wristwatches that run for a year on a battery as small as a dime. 

   Fiberglass materials for rocket-fuel tanks are now employed to make lightweight, high-strength storage tanks, railway tank cars, and highway tankers. A magnetic hammer that originally served to eliminate small imperfections from metal surfaces of the Saturn V rocket is being adapted for use in the automotive and shipbuilding industries. 

   Hundreds of other items could be mentioned:

 an aluminized plastic blanket that can be folded small enough to be carried in a pocket;

a cooler-smoking tobacco pipe, lined with a material developed for nuclear rocket engines;

an ultrasonic testing device that can reveal hidden earthquake damage in masonry structures;

and an improved caulking compound for tiles, derived from sealants used in spacecraft. 

   One of the most valuable contributions of aerospace technology to industry in general is a management technique called the systems approach, or systems engineering. With the aid of computers, this technique brings together all the elements of a complex project--people, money, materials--so that everything is ready at the optimum time. It has been applied to a variety of problems unrelated to space exploration. Among them are cancer research, hospital design and management, city planning, crime detection and prevention, pollution control, building construction, and transportation. 

   In the 1980s advances in electronics--themselves a spin-off--allowed industry to take advantage of aerospace computer software. Automobile manufacturers used a computer program called the Structural Performance and Design program to design improved car bodies. Programs used to train astronauts to meet contingencies during Spacelab missions were used to train fire commanders to make decisions and allocate resources under pressure. This system, called Emergency Management Computer Aided Training (EMCAT), uses a desktop computer and laser disc player to display a burning building. The display responds--the building is consumed in flames or the fire is extinguished, for example--according to the trainee's decisions. EMCAT is similar to having a pilot trainee use a flight simulator. 

   The experience gained from developing NASA spacesuits was applied in the process of designing clothing for use in other professions. Firefighters now have lighter, less bulky breathing apparatuses and special "fireblocking" materials that are more resistant to cracking and burning. Spacers used for ventilation and cushioning in moon boots were adapted for use in athletic shoes that are designed to reduce fatigue and injury. 

 

The military use of space .There are many countries that have got their own military programs they are: the USA, the Russian Federation, China, the European Union (ESA and some individual member states), Japan, India, Ukraine and Israel 13,25,23,33,8

1983 in May, Ronald Reagan proposed to use space-based weapons to shoot down intercontinental ballistic missiles (Strategic Defense Initiative (SDI)). It was supposed to protect the USA from missile attacks. The SDI satellites would track a missile from liftoff, and shoot it down with lasers before the missile cleared the air space of the country from which it was launched. “Star Wars” program caused some international criticism. People were not sure that this system would be used only in purpose of security.

 

1991, the United States used sophisticated satellite technology to pinpoint Iraqi targets during the Persian Gulf War. Intelligence-gathering satellites gave the American forces an unprecedented view of the battleground, showing every move that the Iraqi armies were making during the war.

Since the times of the Cold War, militarization and weaponization of space has become very “popular” all over the world. The USA and the USSR have made this a competition. Today many countries try to use space in military way. “Space-based weapons are possible for any state with the economic and technological capability to manufacture and launch ICBMs or rockets capable of putting satellites into orbit, and to control the actions of missiles and space objects from the ground. Theoretically, this could include the following states: the USA, the Russian Federation, China, the European Union (ESA and some individual member states), Japan, India, Ukraine and Israel. 4

 2007, January 11, China successfully tested a direct assent anti-satellite (ASAT) weapon. So, China has both security and military concepts in outer space. So, we can see that even China (the country that for a long time was against weaponization of space) started to take part in the arms race in outer space. The technology that it used can be also used by other countries. So, people really start to think about their defense. Not so long ago new notions as “space-based defense”, “space-based defense programs”, “space security” appeared.

“Governments do not make decisions to ”weaponize” space . But they do make policies and strategies, establish organizations and create programs to develop and deploy systems to bolster deterrence, strengthen defenses and increase military efficiencies. … are people against placing weapons in space?

Moral, military and strategic contexts make a difference. To ask some one to consider whether they’re in favor of putting weapons in space is different from asking that same person whether he would support basing interceptors in orbit to intercept long-range ballistic missiles to protect his city. Indeed, when asked about whether they want a missile defense, polls have consistently shown over the past two decades that the American people support such defenses. It is also quite a different thing to ask a person whether he would support the development of a weapon, a tool, to physically knock out a satellite that had uncovered the positions of our sons on uniform, who happened to be concerned in some dangerous valley in Afganistan. Who would not favor removing the threat?

Second there is the historical context to consider. Critics of expanding the military uses of space are wont to make a clean-cut distinction between ”militarizing” space, on the one hand, which they say already has happened, and” weaponizing” space on the other, which they say has yet to occur.” Steven Lambakis4 rises a question that  doesn’t have a definite answer. Each position has its pros and cons and it is quite difficult to choose at once and to take a stable position. That is just a question “to be or not to be”.

 

 

 

 

Conclusion.

“Space is the most fragile environment that exists because it has the least ability to repair itself” Joel R. Primack (cm) People started to make use of space,  but they didn’t think about the  consequences. Many countries do this: China, the European Union (ESA and some individual member states), Japan, India, Ukraine and Israel. 34

 We can say all countries try to win the competition “citius, altius, fortius”. They create many space-based weapons and space equipment, and the question of our future is becoming more and more acute. They are creating space defense programs in order to be on the safe side but what if the countries are trying to build “the Time Machine”?
