Learn about the history and future of human space exploration.
Explanation
Space exploration began in earnest during the Space Race between the United States and the Soviet Union in the 1950s and 1960s. The Soviet Union launched Sputnik, the first satellite, in 1957, and the U.S. landed astronauts on the Moon in 1969.

Future goals include returning humans to the Moon, sending astronauts to Mars, and searching for signs of life beyond Earth.
