Space exploration is the exploration of the universe beyond Earth. It involves sending spacecraft into space to study celestial bodies, such as planets, moons, asteroids, and comets.
History of Space Exploration
- Early Rockets: The first rockets were developed centuries ago, but it wasn’t until the 20th century that they became powerful enough to reach space.
- Space Race: The Cold War-era Space Race between the United States and the Soviet Union led to rapid advancements in space technology.
- First Satellites: The first artificial satellite, Sputnik 1, was launched by the Soviet Union in 1957.
- First Humans in Space: The first human to travel into space was Yuri Gagarin, a Soviet cosmonaut, in 1961.
- Moon Landing: The Apollo 11 mission in 1969 was a historic milestone as it landed the first humans on the Moon.
Goals of Space Exploration
- Scientific Discovery: Space exploration aims to expand our understanding of the universe, from the formation of planets to the search for extraterrestrial life.
