Diksia.com - The images of Earth from space that we have seen so far are a long process that scientists have been doing for a long time. The process of taking images of Earth began in 1946, from images that weren't clear until they were clear.
Photographing the Earth from space was very difficult and required launching a rocket. The resulting images are experiments from different angles and thousands of kilometers from Earth.
In 1946, a major milestone in space exploration occurred when a 35-millimeter film camera captured the first images of Earth from space every one and a half seconds.
Exactly on October 24, 1946, the camera was fired from a V-2 rocket from the White Sands Missile Range in the United States. This marks the official crossing of the Kármán Line, the boundary between Earth's atmosphere and space, as quoted by Business Today.
Although the rocket landed suddenly and hit the ground at a speed of more than 340 mph (547 km/h), the film wrapped in steel tape miraculously survived. This can then store historical images of the earth.
After World War II, the U.S. Army again used captured German V-2 rockets for scientific exploration, including atmospheric research and improving missile defenses.
Equipped with scientific instruments, these newly designed rockets launched various missions between 1946 and 1950 and captured more than 1,000 images of the Earth from an altitude of more than 100 miles.
According to NASA's website, the Explorer 6 satellite took the first photo of Earth on August 14, 1959 from an orbit at an altitude of about 27,359 km, but the results lacked details.
Then, on April 1, 1960, the TIROS-1 weather satellite transmitted images of the Earth from an orbital altitude of about 724 km with sufficient quality for weather forecasting, in accordance with the main purpose of the satellite itself.
The image of the Earth itself as a complete disk was successfully captured by the Soviet communications satellite Molniya 1-3 on May 30, 1966, although with less good results.
