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]
AstroForge's ultimate goal in the field of asteroid mining is the extraction, refinement, and sale of platinum-group metals (PGMs) located within M-type asteroids near to Earth. These asteroids are expected to be quite small in comparison to main belt asteroids, being anywhere from around 20 to 300 meters in diameter.
The authors' model posits that space mining would become more attractive under several conditions: when environmental regulations increase the cost of terrestrial mining, when research and development improves the efficiency of space mining technology, and when higher-grade mineral deposits become available in space compared to Earth. The paper ...
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]
Zecharia Sitchin (July 11, 1920 – October 9, 2010) [1] was an author of a number of books proposing an explanation for human origins involving ancient astronauts.Sitchin attributed the creation of the ancient Sumerian culture to the Anunnaki, which he claimed was a race of extraterrestrials from a planet beyond Neptune called Nibiru.
They have been used in space—including on the Moon—for decades. The usual process is to source the suitable substances from Earth, but plutonium-238 or strontium-90 could be produced on the Moon if feedstocks such as spent nuclear fuel are present (either delivered from Earth for processing or produced by local fission reactors). RTGs could ...

Seveneves is a science fiction novel by Neal Stephenson published in 2015. The story tells of the desperate efforts to preserve Homo sapiens in the wake of apocalyptic events on Earth after the unexplained disintegration of the Moon and the remaking of human society as a space-based civilization after a severe genetic bottleneck.
