👉 Sputniks were a Soviet satellite launched into low Earth orbit in 1957 by the Russian rocket manufacturer, F-123. These were used as early warning and reconnaissance satellites to detect potential threats before they could cause significant damage or destruction on Earth. They were also used to monitor the Earth's atmosphere for atmospheric gases and other pollutants. The Sputniks were a major milestone in space exploration, marking the first time humans had seen the Earth from space.
