Space exploration
Space exploration involves deploying satellites, robotic probes, telescopes, and human crews via spacecraft to investigate outer space, celestial bodies, and the broader universe, yielding empirical data on cosmic phenomena, planetary geology, and potential habitability. Pioneered amid Cold War rivalry, it has produced breakthroughs like the first artificial satellite, Sputnik 1 , launched by the Soviet Union on October 4, 1957, which orbited Earth and transmitted radio signals, proving practical rocketry for space access. Yuri Gagarin 's Vostok 1 flight on April 12, 1961, made him the first human to reach space, completing one orbit and demonstrating human viability in microgravity. The United States responded with Project Apollo, culminating in the July 20, 1969, lunar landing by Neil Armstrong and Buzz Aldrin aboard Apollo 11 , where they collected 21.5 kilograms of Moon rocks and conducted experiments revealing solar wind and seismic activity. Subsequent endeavors established the International Space Station
