Before 1970, asteroid mining existed largely within the realm of science fiction. Publications such as Worlds of If, [8] Scavengers in Space, [9] and Miners in the Sky [10] told stories about the conceived dangers, motives, and experiences of mining asteroids.
Asteroids, including those in the asteroid belt, have been suggested as possible sites of space colonization. [1] Motives include the survival of humanity, and the specific economic opportunity for asteroid mining. Obstacles include transportation distance, temperature, radiation, lack of gravity, and psychological issues.
Asteroid mining will likely be a key player in space colonization. Water and materials to make structures and shielding can be easily found in asteroids. Instead of resupplying on Earth, mining and fuel stations need to be established on asteroids to facilitate better space travel. [61]
The economic potential of space exploration goes beyond just mining asteroids. McKinsey predicts that the global space economy will grow from $630 billion in 2023 to $1.8 trillion by 2035, even ...
Mining the Sky: Untold Riches from the Asteroids, Comets, and Planets, is a 1997 book by University of Arizona Planetary Sciences professor emeritus John S. Lewis that describes possible routes for accessing extraterrestrial resources, either for use on Earth or for enabling space colonization. [1]

Water molecules have been detected on the surface of asteroids for the first time, proving that these remnants from the formation of our solar system aren’t just dried-up space rocks.
So far, every asteroid with moons has turned out to be a rubble pile, a loose conglomeration of rock and metal that may be half empty space by volume. The investigated asteroids are as large as 280 km in diameter, and include 121 Hermione (268×186×183 km), and 87 Sylvia (384×262×232 km).
