Space, cosmos, universe - are notions that are controversial topics for scholars of all time, ranging from mysticism to complex definitions. Cosmic space is an infinite territory for man, but man is tempted to explore it, even if the necessary technological developments are extremely small. Over time, several sciences and methods of cosmic space analysis have been invented: from observations made from Earth (astronomy) to those in the cosmic space adjacent to our planet, or even the exploration of heavenly bodies, either by humans such as the Moon's example), or using satellites, probes, and robots. The cosmic space is considered to be the infinite expanse beyond the Earth's atmosphere, having a consistency and rules of composition and function totally different from the laws of physics on Earth. For man to travel in space, he needs to know much more about it. So, sciences dealing with the analysis and monitoring of cosmic space are now the most complex of humanity. The more we understand about how extra-terrestrial space works, the more we have the chance to understand more about our planet and about life on Earth.
