It is also the nearest celestial body to our planet, and selenology, or the study of the moon, is very important for scientists, as it can give them insights into other celestial bodies and advance planetary science. If we want to know the history of Earth, together with the history of our solar system, studying the moon is essential. The exploration of the moon started in the 1950s. In those days, however, lunar missions were driven by politics, because the Soviet Union and the United States tried to achieve "the first" in every sphere of selenology. While the first moon flyby, the first impact, the first soft landing and the first orbiter of the moon were achieved by the Soviet Union, the US became the first country to land man on the lunar surface, which in a way ended the "moon race".

So the US cancelled its Apollo program, and for more than half a century, no astronaut has landed on the moon. The second tide of lunar explorations began in the 1990s. Apart from the US, countries like Japan, European states, China and India have sent probes to the Moon. Unlike the moon race in during the Cold War days, this time the purpose of lunar explorations is to achieve scientific and engineering goals. Nowadays, countries capable of space exploration pay more attention to efficiency. Due to such explorations, wat...
