Space exploration is the ongoing discovery and study of celestial structures in outer space. It began in 1957 with the launch of Sputnik 1, the first artificial satellite, by the Soviet Union. The first human spaceflight was achieved by Yuri Gagarin in 1961. Space missions, including the Apollo Moon landings, have significantly advanced scientific knowledge. Space exploration is expensive and requires significant investment from governments and private entities. While satellites are used extensively for communication and navigation, space tourism is a relatively new concept, with only a few wealthy individuals having experienced it. Critics argue that resources spent on space exploration could be better used to solve problems on Earth, such as poverty and climate change.
