The images of the Earth from space that we have seen so far are a long process carried out by scientists for a long time. The process of taking pictures of the Earth began in 1946, from images that were not clear until they were clear.
Taking pictures of the Earth from space was done with great difficulty and had to launch a missile. The resulting images are experiments from various viewpoints and thousands of kilometers from Earth.
How to Take Pictures of Earth for the First Time
In 1946, a major milestone in space exploration occurred when a 35-millimeter motion-picture camera took the first images of Earth from space every one and a half seconds.
Precisely on October 24 1946, the camera was launched with a V-2 missile 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 outer space, as quoted from Business Today.
Even though the missile landed suddenly and hit the ground at a speed of more than 547 km per hour, the film encased in steel tape miraculously survived. This can then store historical images of the Earth.
Exploration for Atmospheric Research
After World War II, the United States Army again used captured German V-2 missiles for scientific exploration, including atmospheric research and improving missile defenses.
Equipped with scientific instruments, these redesigned missiles embarked on various missions between 1946 and 1950, capturing more than 1,000 images of the Earth from an altitude of more than 160 kilometers.
Quoted from the site NASAon August 14, 1959, the Explorer 6 satellite took the first photo of Earth from an orbit as high as about 27,359 km, but the results lacked detail.
Then on April 1, 1960, the TIROS-1 weather satellite returned images of the Earth from an orbital altitude of about 724 km with sufficient quality for weather forecasting, according to the main purpose of the satellite itself.
The image of the Earth as a full disk itself was successfully taken by the Soviet communications satellite Molniya 1-3 on May 30 1966, although with less than good results.
The camera that also contributed was Clyde Holliday’s camera. The camera is designed for space imaging. Clyde’s camera was instrumental in capturing the first-ever photograph of Earth from space during a V-2 missile launch at the White Sands Missile Range.
Returning the images to Earth, Clyde Holliday and his team conducted careful analysis. They extract valuable insights into geology, meteorology, and the imaging field itself.
As technology advanced and the Apollo astronauts began moon missions, cameras captured iconic and more detailed images of the Earth. This image is able to reveal the complex features of the Earth.
Pictures of the Earth taken from the Moon
In scientific exploration, images of the Earth have also been taken from the Moon. The photo was taken on April 30, 1967 by the Surveyor 3 robotic lander which was later visited by the Apollo 12 astronauts.
The Apollo missions of the late 1960s and early 1970s produced thousands of stunning images. Among them are photos that show how small and fragile the Earth is in the midst of the darkness and vastness of space.
The most famous photo is the photo of Earthrise taken by Apollo 8, the first manned mission to orbit the Moon in December 1968.
In July 1969, the first human landing mission on the moon, Apollo 11, returned many iconic photos of Nel A. Armstrong and Edwin E. The famous image of the blue marble Earth that we often see on the internet is an image taken in December 1972 by Apollo 17 of a distance of 115,872 km during their journey to the Moon.
Meanwhile, on March 8 2004, the Mars Exploration Rover Spirit showed a perspective of Earth that looked like nothing more than a bright star. Then 12 years ago, the Moon and Earth were photographed simultaneously during the uncrewed Artemis I mission from a distance of 432 km from Earth.
