Early Space Exploration History
The Space Age’s Inception
On October 4, 1957, the Soviet Union launched Sputnik 1, the first artificial satellite in history, thereby ushering in the Space Age. This momentous occasion signaled the beginning of human exploration of space and set off the space race, a period of fierce rivalry between the US and the USSR.
Sputnik 1: This 58 cm (23 inch) satellite proved it was possible to launch items into orbit around the Earth by transmitting radio pulses that could be detected from the ground. It weighed around 83 kg (183 lbs).
Explorer 1: On January 31, 1958, the United States launched Explorer 1, their first satellite, in retaliation. The significance of conducting scientific study in space was underscored by the mission’s discovery of the Van Allen radiation belts, which are areas of charged particles trapped by Earth’s magnetic field.
The First Person in Space
Human spaceflight was the next significant achievement. Yuri Gagarin, a Soviet cosmonaut, became the first person to orbit the Earth on Vostok 1 on April 12, 1961. Gagarin’s historic 108-minute trip demonstrated that people could live and work in the hostile environment of space.
The Moon Landing and the Apollo Program
In response to Gagarin’s mission, the US launched the audacious Apollo program, which sought to put people on the moon. A major advancement in science and technology was made possible by the Apollo program.
Apollo 11: Michael Collins orbited above in the command module on July 20, 1969, as astronauts Neil Armstrong and Edwin “Buzz” Aldrin successfully touched down on the Moon. Armstrong’s well-known quote, “That’s one small step for [a] man, one giant leap for mankind,” represented a significant accomplishment for all of humankind, not just for the United States.
Scientific Discoveries: 382 kg (842 lbs) of lunar rocks and soil were returned by the Apollo missions (11 through 17), and these samples have been instrumental in revealing important details about the Moon’s composition, geological past, and early solar system. The ability of people to function well in space was also shown by these missions.
The Development of Space Travel
