One of the psychological states experienced by astronauts, which scientists call the "overview effect," involves the realization of Earth’s fragility and vulnerability and a desire to protect it. Due to this effect, all political, interethnic, and other conflicts occurring on our planet seem insignificant in the face of other threats.
Yuri Gagarin was the first to experience the "overview effect." One of his most famous quotes about Earth is: "Orbiting Earth in the spaceship, I saw how beautiful our planet is. People, let us preserve and increase this beauty, not destroy it."
In 1968, astronaut William Anders during the Apollo 8 mission took the photograph "Earthrise." In the photo, Earth is seen rising above the lunar horizon instead of the sun, which is familiar to humans. This image spread across all countries and continents within days and appeared on the covers of the most fashionable and reputable magazines, such as Time. Thanks to this photograph, millions of people on Earth simultaneously experienced the "overview effect," which marked the beginning of environmental movements worldwide.
The term "overview effect" was first used by writer Frank White in 1987 in his book "The Overview Effect: Space Exploration and Human Evolution."
Thus, we see that individuals involved in space exploration undergo a shift in consciousness toward caring for humanity as a species and for our planet, and space serves as an effective tool for diplomacy.
