Since the launch of Sputnik-1, which became the first artificial satellite of the Earth, 60 years will be celebrated in a year and a half. Since then, man has repeatedly sent into space a variety of spacecraft, animals and people.

Colorful infographics span all the way from 1959 to 2015 and graphically show more than 100 research probes, descent vehicles and rovers on a map.

At the top of the poster, you can see the path that spacecraft have covered, and the bottom shows how these vehicles looked. All devices are grouped by flight direction.

And although most of them have never left Earth’s orbit, the map shows what incredible distances man has managed to overcome in the solar system!

Outer space (outer space) - relatively empty sections of the universe that lie outside the boundaries of the atmospheres of celestial bodies. Contrary to popular belief, space is not an absolutely empty space - it has a very low density of some particles (mainly hydrogen), as well as electromagnetic radiation and interstellar matter.

Etymology

In its original understanding, the Greek term "cosmos" (order, world order) had a philosophical basis, defining a hypothetical closed vacuum around the Earth - the center of the universe. Nevertheless, in Latin-based languages ​​and its borrowings, the practical term “space” is applied to the same semantics (since from the scientific point of view the vacuum enveloping the Earth is infinite), therefore, a peculiar oxymoron “space space".

Borders

There is no clear boundary, the atmosphere is rarefied gradually as it moves away from the earth’s surface, and there is still no consensus on what to consider as a factor in the beginning of space. If the temperature were constant, then the pressure would change exponentially from 100 kPa at sea level to zero. The International Aviation Federation has set a height of 100 km (the Karman line) as the working boundary between the atmosphere and space, because at this altitude it is necessary for the aircraft to move at the first cosmic speed to create a lifting aerodynamic force, which makes the meaning of air travel impossible. Astronomers from the USA and Canada measured the boundary of the influence of atmospheric winds and the beginning of the impact of cosmic particles. It was at an altitude of 118 kilometers, although NASA itself considered 122 km as the border of space. At this altitude, the shuttles switched from conventional maneuvering using only rocket engines to aerodynamic ones with "support" to the atmosphere.

solar system

Space in the solar system is called interplanetary space, which passes into interstellar space at the heliopause points of the solstice. The vacuum of space is in fact not absolute - it contains atoms and molecules detected by microwave spectroscopy, the relict radiation left from the Big Bang, and cosmic rays that contain ionized atomic nuclei and various subatomic particles. There is also gas, plasma, dust, small meteors and space debris (materials left over from human activities in orbit). The absence of air makes outer space (and the surface of the moon) ideal sites for astronomical observations at all wavelengths of the electromagnetic spectrum. Proof of this are photographs taken with the Hubble Space Telescope. In addition, invaluable information about the planets, asteroids and comets of the solar system is obtained using spacecraft.

The impact of being in outer space on the human body

According to NASA scientists, contrary to popular belief, if you enter outer space without a protective suit, a person will not freeze, will not explode, and will not immediately lose consciousness, his blood will not boil - instead, death will come from a lack of oxygen. The danger lies in the decompression process itself - it is this period of time that is most dangerous for the body, since with explosive decompression the gas bubbles in the blood begin to expand. If refrigerant (such as nitrogen) is present, then under these conditions it freezes the blood. In space conditions there is not enough pressure to maintain the liquid state of the substance (only a gaseous or solid state is possible, with the exception of liquid helium), therefore, first, water will evaporate quickly from the mucous membranes of the body (tongue, eyes, lungs). Some other problems - decompression sickness, sunburn of unprotected skin and damage to the subcutaneous tissue - will begin to affect after 10 seconds. At some point, a person will lose consciousness due to a lack of oxygen. Death can occur in about 1-2 minutes, although this is not known exactly. However, if you do not hold your breath in your lungs (an attempt to hold it will lead to barotrauma), then 30-60 seconds in outer space will not cause any irreversible damage to the human body.

NASA describes a case where a person accidentally finds himself in a space close to a vacuum (pressure below 1 Pa) due to air leakage from a spacesuit. The person remained conscious for approximately 14 seconds - approximately this time is required for oxygen-depleted blood to enter the lungs from the brain. There was no complete vacuum inside the suit, and recompression of the test chamber began after about 15 seconds. Consciousness returned to man when pressure rose to an equivalent height of about 4.6 km. Later, a man who got into a vacuum told how he felt and heard air coming out of him, and his last conscious memory was that he felt water boiling in his tongue.

On February 13, 1995, Aviation Week and Space Technology magazine published a letter describing the incident that occurred on August 16, 1960, during the lifting of a stratostat with an open gondola to a height of 19.5 miles for a record parachute jump (Project Excelsior "). The right hand of the pilot was depressurized, but he decided to continue the ascent. The hand, as one might expect, was extremely painful, and could not be used. However, when the pilot returned to the denser layers of the atmosphere, the state of the arm returned to normal.

  • 80.45 km (50 miles) is the official height of the space border in the United States.
  • 100 km - the official international border between the atmosphere and space is the Karman line, which defines the boundary between aeronautics and space.

  • 1000–1100 km is the maximum height of auroras, the last manifestation of the atmosphere visible from the Earth’s surface (but usually well-marked auroras occur at altitudes of 90–400 km).

In the first half of the 20th century, this height was considered the theoretical limit of the existence of the atmosphere. If the whole atmosphere rotated uniformly with the Earth, then from this height at the equator the centrifugal force of rotation will exceed the gravitational forces, and air molecules that go beyond this boundary will scatter in different directions. In fact, the phenomenon of atmospheric scattering takes place, but it occurs due to the thermal and corpuscular action of the Sun in the entire exosphere at altitudes from 400 to ~ 100 thousand km (see above).
  • OK. 90,000 km - the distance to the head shock wave formed by the collision of the Earth's magnetosphere with the solar wind.

The speeds required to enter the near and far space

In order to enter orbit, the body must reach a certain speed. Cosmic speeds for the Earth:

  • The first cosmic speed - 7.9 km / s - the speed for entering into orbit around the Earth;
  • The second cosmic velocity - 11.1 km / s - is the velocity for moving away from the sphere of gravity of the Earth and entering the interplanetary space;
  • The third cosmic velocity - 16.67 km / s - the speed to escape from the sphere of gravity of the Sun and exit into interstellar space;
  • The fourth cosmic speed - about 550 km / s - is the speed for moving away from the sphere of gravity of the Milky Way galaxy and entering the intergalactic space.

For comparison, the speed of the Sun relative to the center of the galaxy is approximately 220 km / s.

If any of the speeds is less than the specified, then the body will not be able to enter the corresponding orbit (the statement is true only for launching at the indicated speed from the surface of the Earth and further movement without traction).

The first who realized that to achieve such speeds when using any chemical fuel, a multi-stage rocket using liquid fuel was needed, was Konstantin Eduardovich Tsiolkovsky.
