Space, or outer space, is the void existed between celestial bodies. That void is not completely empty. It also contains a low density of some particles, especially, hydrogen, electromagnetic radiation and interstellar medium. Scientists argue where the boundary between the atmosphere of the Earth and the space is because the density of the atmosphere decreases gradually as the altitude increases.
There are many space secrets. Many things concerning the space are not known or not studied. Anyway, modern people, especially scientists and astronauts, do their best to study the space. Yuri Gagarin was the first human to journey into outer space. His spacecraft completed the Earth orbit on the 12th of April in 1961. After that in 1969 the spacecraft “Apolo-11” landed humans on the Moon. Nowadays the International Space Station works in low Earth orbit.
One of the problems concerning the work of the astronauts is safety. First of all, it is the threat of orbital debris. It containing different objects such as spent rocket stages, different materials, defunct satellites and so on. One more problem is radiation. An astronaut in the space experiences the dose of radiation per day which a human on the Earth experiences per year.
