Event Name:  Outer space
Event Description:  , or simply space, is the space between celestial bodies, including Earth. [1] It is not completely empty, but consists of a relative vacuum consisting of low density of particles (mostly hydrogen plasma and helium, as well as electromagnetic radiation, magnetic fields) and neutrons (recent observations have shown that it contains matter and dark energy as well). The baseline temperature, determined by residual radiation due to the Big Bang, is 2,7 Kelvin (k) [2]. Ultra-low-density plasma (less than one hydrogen atom per cubic meter) and high temperature (millions of Kelvin degrees) in intergalactic space are accounted for in most of the ordinary baryon issue in outer space; local concentrations have increased to stars and galaxies. Intergalactic space is larger than the universe, and even galaxies and star systems are mostly empty and planets occupy almost empty space. There is no specific limit to the beginning of outer space, but in general, the Caraman line at 100 km (62 miles) above sea level was adopted as a starting point for outer space in order to record atmospheric measurements, treaties and space conventions. The general framework of international space law was established through the Outer Space Convention, which was passed through the United Nations in 1967. The Convention prohibits any State from claiming sovereignty over space and allows all States to freely explore space. In 1979, the Moon Convention, which made the roofs of planets and orbits around them, was placed under the authority of the international community. Other provisions of the Convention relating to the peaceful use of outer space have been added by the United Nations but have not prohibited the deployment of weapons in space, including live tests of anti-satellite missiles. Humans began to discover the physical space during the 20th century through high-altitude balloon flights, followed by the launch of individual rockets in multiple stages. Yuri Kakarin of the Soviet Union was the first to discover Earth's orbit in 1961. Since then unmanned spacecraft have reached all known planets in the solar system. Due to the high cost of access to the space, the journeys did not exceed the limits of the moon. In 2012, Voyager 1 became the first man-made vehicle to reach the bingeme field. Requires access to the lowest earth orbit at speeds of up to 28,100 km / h (17,500 mph), much faster than any conventional vehicle. Outer space is also a challenging environment for human discovery because of the dangers of double space and radiation. Non-gravity has a detrimental effect on human organ function, leading to muscle atrophy and osteoporosis. Manned space flights have been confined to the low Earth and the moon, and the solar system has been unmanned; the rest of outer space remains impossible for humans to use except for the telescope
