Space exploration

Space exploration is the physical exploration of outer space. The politics, science, and engineering behind space flight all fall under the auspices of space exploration. There are many rationales behind space exploration; among the most common are the ones focusing on scientific research or the future survival of humanity. This endeavour has been to some degree a dream and goal of humanity for the past several centuries, but it was not until the development of large liquid-fueled rocket engines during the early 20th century that it really began to be seriously developed.
