Since the launch of Sputnik-1, which became the first artificial satellite of the Earth, in six months will be 60 years old. Since then, people have repeatedly sent to space a variety of spacecraft, animals and people.

Colorful infographics cover the whole journey from 1959 to 2015 and visually shows on the map more than 100 research probes, descent vehicles and rovers.

At the top of the poster, you can see the path that the spaceships have overcome, and the bottom shows how these vehicles looked. All vehicles are grouped in the directions of flight.

And let most of them never leave the Earth's orbit, the map demonstrates what incredible distances in the solar system managed to overcome the man!

Cosmic space (space) - relatively empty parts of the universe, which lie outside the boundaries of the atmosphere of heavenly bodies. Contrary to popular belief, space is not an absolutely empty space - there is 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 languages ​​and its borrowings to the same semantics, the practical term "space" is used (since from the scientific point of view, the enveloping vacuum is endless in the world), therefore, in the Russian and its close languages, as a result of the reformulation, an original oxymoron "cosmic space".

Borders

There is no clear boundary, the atmosphere is gradually diluted with distance from the earth's surface, and there is still no consensus on what to consider as a factor in the beginning of the cosmos. If the temperature were constant, the pressure would vary exponentially from 100 kPa at sea level to zero. The International Aeronautical Federation, as the working boundary between the atmosphere and the cosmos, has established a height of 100 km (the Karman line), because at this altitude, to create an aerodynamic lift, it is necessary for the aircraft to move with the first space velocity, thereby losing the meaning of the air flight. Astronomers from the United States and Canada measured the boundary of the effect of atmospheric winds and the onset of the impact of cosmic particles. She was at an altitude of 118 kilometers, although NASA itself considers the space border 122 km. At this altitude, the shuttles switched from normal maneuvering using only rocket engines to aerodynamic ones with a "support" to the atmosphere.

solar system

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

The impact of being in outer space on the human body

According to NASA scientists, contrary to popular beliefs, when a person enters open space without a protective suit, a person does not freeze, explodes and instantly does not lose consciousness, his blood does not boil - instead death will come from lack of oxygen. The danger lies in the very process of decompression - it is this time period that is most dangerous for the body, as in the case of explosive decompression gas bubbles in the blood begin to expand. If there is a refrigerant (for example, nitrogen), then under such conditions it freezes the blood. Under cosmic 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), so water will begin to evaporate quickly from the mucous membranes of the body (tongue, eyes, lungs). Some other problems - decompression sickness, sunburn of unprotected skin areas and damage to subcutaneous tissues - will begin to affect after 10 seconds. At some point a person will lose consciousness because of lack of oxygen. Death may occur in about 1-2 minutes, although this is not known. Nevertheless, if you do not hold your breath in the lungs (an attempt at delay will lead to barotrauma), 30-60 seconds of being in the open space will not cause any irreversible damage to the human body.

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

On February 13, 1995, Aviation Week and Space Technology published a letter describing the incident of August 16, 1960, during the lifting of a 19.5-mile open gondola with a nacelle for a record parachute jump (Excelsior Project "). The right hand of the pilot was depressurized, but he decided to continue the climb. The hand, as might be expected, was extremely painful, and it could not be used. However, when the pilot returned to the denser atmosphere, the state of the hand returned to normal.

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 altitude at the equator the centrifugal force of rotation will exceed the gravitational forces, and the air molecules that go beyond this boundary will scatter in different directions. In fact, the phenomenon of atmospheric scattering takes place, but it occurs because of the thermal and corpuscular action of the Sun in the entire volume of the exosphere at altitudes from 400 to ~ 100 thousand km (see above).

The speeds necessary to reach near and far space

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

  • The first space velocity is 7.9 km / s - the speed to enter orbit around the Earth;
  • The second space velocity is 11.1 km / s - the speed for leaving the sphere of gravity of the Earth and reaching the interplanetary space;
  • The third space velocity is 16.67 km / s - the speed for leaving the sphere of gravity of the Sun and reaching the interstellar space;
  • The fourth cosmic speed is about 550 km / s - the speed for leaving the sphere of attraction of the Milky Way galaxy and reaching the intergalactic space.

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

If any of the speeds is less than the specified one, the body will not be able to reach the corresponding orbit (the statement is true only for starting with 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 requires a multi-stage liquid fuel rocket, was Konstantin Eduardovich Tsiolkovsky.
