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

Colorful infographics covers all the way from 1959 to 2015 and clearly shows on the map more than 100 research probes, descent vehicles and mars rovers.

In the upper part of the poster you can see the path that the spacecraft crossed, and in the lower part you can see how these vehicles looked. All vehicles are grouped by flight directions.

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

Outer space (space) - relatively empty areas of the Universe, which lie outside the boundaries of the atmospheres of celestial bodies. Contrary to popular belief, space is not an absolutely empty space - there is a very low density of some particles (mostly hydrogen), as well as electromagnetic radiation and interstellar matter.

Etymology

In its original understanding of the Greek term "space" (order, world order) had a philosophical basis, defining a hypothetical closed vacuum around the Earth - the center of the Universe. However, in the Latin-based languages ​​and its borrowings, the practical term “space” is used to the same semantics (since scientifically the vacuum enveloping the Earth is infinite), therefore in Russian and close to him, as a result of the reform adjustment, a kind of oxymoron “cosmic space".

Boundaries

There is no clear boundary, the atmosphere is gradually diluted 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 the cosmos. If the temperature were constant, then the pressure would change exponentially from 100 kPa at sea level to zero. The International Aviation Federation, as a working boundary between the atmosphere and space, set a height of 100 km (the Karman line), because at this altitude, to create aerodynamic lift force, it is necessary for the aircraft to move with the first space velocity, which makes it lose its meaning. Astronomers from the USA and Canada measured the boundary of the influence of atmospheric winds and the onset of the effects of cosmic particles. She was at an altitude of 118 kilometers, although NASA themselves consider 122 km as the boundary of space. At such an altitude, the shuttles switched from conventional maneuvering using only rocket engines to aerodynamic ones with a “footing” to the atmosphere.

solar system

The 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 not really absolute - it contains atoms and molecules detected by microwave spectroscopy, the relic radiation left from the Big Bang, and cosmic rays, which contain ionized atomic nuclei and various subatomic particles. There is also gas, plasma, dust, small meteors and space debris (materials left over from human activity 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 they enter space without a protective suit, a person will not freeze, will not explode and will not immediately faint, his blood will not boil - instead, death will result 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 organism, since with explosive decompression gas bubbles in the blood begin to expand. If a refrigerant is present (for example, nitrogen), then under such conditions it freezes the blood. Under space conditions, there is not enough pressure to maintain the liquid state of the substance (only gaseous or solid state is possible, with the exception of liquid helium), therefore, first the water begins to evaporate quickly from the mucous membranes of the body (tongue, eyes, lungs). Some other problems - decompression sickness, sunburns of unprotected skin areas and damage to the subcutaneous tissues - will begin to appear in 10 seconds. At some point, the person will lose consciousness due to lack of oxygen. Death can occur in about 1-2 minutes, although it is not known for sure. However, if you do not hold your breath in the lungs (an attempt to delay will lead to barotrauma), then 30-60 seconds of being in outer space will not cause any irreversible damage to the human body.

NASA describes a case in which a person happened to be 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 the time it takes for the blood depleted of oxygen to pass from the lungs to the brain. A full vacuum did not appear inside the suit, and the recompression of the test chamber began after approximately 15 seconds. Consciousness returned to the person when the pressure rose to an equivalent height of about 4.6 km. Later, a person caught in a vacuum told how he felt and heard the air coming out of him, and his last conscious memory was that he felt the water in his tongue boil.

The magazine “Aviation Week and Space Technology” on February 13, 1995 published a letter in which it was told about the incident that took place on August 16, 1960, when a stratostat was raised from an open gondola to an altitude of 19.5 miles to make a record parachute jump (Excelsior "). The pilot's right hand was depressurized, but he decided to continue the climb. The hand, as could be expected, experienced extremely painful sensations, and it could not be used. However, when the pilot returned to the more dense layers of the atmosphere, the state of the arm returned to normal.

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

The speed required to enter the near and far space

In order to go into orbit, the body must reach a certain speed. Space speeds for the Earth:

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

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

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

The first who realized that to achieve such speeds when using any chemical fuel, a multistage liquid fuel rocket was needed was Konstantin E. Tsiolkovsky.
