Space Exploration and the New Space Race (1957–Present): Full Detailed Explanation
Introduction
Space Exploration is the discovery and study of outer space using satellites, telescopes, robotic spacecraft, and human space missions.
The New Space Race refers to the renewed competition among countries and private companies to explore the Moon, Mars, and beyond, while also developing advanced satellite technology, reusable rockets, and space-based industries.
Today, space is important not only for scientific research but also for:
National security.
Communication.
Navigation.
Weather forecasting.
Disaster management.
Economic development.

The Beginning of the Space Age
The Space Age officially began on 4 October 1957, when the Soviet Union launched Sputnik 1, the world's first artificial satellite.
Sputnik:
Orbited Earth successfully.
Shocked the United States.
Started the Space Race between the Soviet Union and the United States.
---
The Cold War Space Race
During the Cold War, space exploration became a symbol of technological and political superiority.
Soviet Achievements
The Soviet Union achieved several major firsts:
First satellite (Sputnik 1).
First living creature in orbit (Laika the dog).
First human in space: Yuri Gagarin (1961).
First woman in space: Valentina Tereshkova (1963).
First spacewalk (1965).
