A relatively resource-poor LL chondrite asteroid contains 20% iron, as well as a significant quantity of volatiles in the form of water, minerals and oxygen. Although it is possible to bring these resources back to Earth, due to its high cost and the abundance of resources on Earth, the primary goal of asteroid Retrieval in the near future will be for processing and utilization in space immediately after collection.[10] The advantage of obtaining resources from asteroids compared to sending those resources from earth is its relative low cost. Using conventional chemical propulsion, it is estimated by NASA that delivering one kilogram of mass to a high lunar orbit costs $100K.
