Igneous Rock Associations 24. Near-Earth Asteroid Resources: A Review

Abstract: The extraction of natural resources located beyond Earth to create products can be described as space resource utilization (SRU). SRU is under active investigation in both the public and private sectors. Near-Earth asteroids (NEAs) are particularly promising early SRU targets due to their relative proximity and enrichments in two key resources: water and platinum group elements (PGEs). Water can be used to create rocket propellant, making it the only resource with significant demand given the current nascent s… Show more

“…The use of recyclable plastics will maximise the material and energy efficiency of the system, as will the recycling of agricultural nutrients and water from human waste. Near-earth asteroids are another potentially rich source of resources, such as water and platinum group metals, which may be valuable as commodities in Earth's global economy, or for supplying Lunar or Martian settlements [14][15][16][17][18][19][20]. However, given the additional challenges of extracting and transporting resources from asteroids, exploration of this opportunity is left for future work.…”
