The history of satellite technology began on October 4, 1957, when the former Soviet Union launched Sputnik-1, the first artificial satellite, into Earth’s orbit. This event marked the dawn of the space age and led to rapid advancements in space exploration and satellite technology. Over the past 67 years, several countries have actively launched satellites for various purposes, such as military defense, weather forecasting, communication, navigation, and deep space research.
Today, more than 80 countries have their own satellites in space, but only a few nations dominate the field with the highest number of satellites. Below is a detailed breakdown of the top seven countries leading in satellite deployment.
