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 ...
Space-based economy is economic activity in outer space, including asteroid mining, space manufacturing, space trade, space burial, space advertising and construction performed in space such as the building of space stations [1]. Space-based industrial efforts are presently in their infancy.
ISRU reverse water gas shift testbed (NASA KSC) ISRU Pilot Excavator – A NASA project. In space exploration, in situ resource utilization (ISRU) is the practice of collection, processing, storing and use of materials found or manufactured on other astronomical objects (the Moon, Mars, asteroids, etc.) that replace materials that would otherwise be brought from Earth.
The World Is Not Enough (WINE) is a US project developing a refuelable steam engine system for spacecraft propulsion.WINE developed a method of extracting volatiles from ice, ice-rich regolith, and hydrated soils and uses it as steam propulsion which allows the spacecraft to refuel multiple times and have an extraordinary long service lifetime.
Space manufacturing or In-space manufacturing (ISM in short) is the fabrication, assembly or integration of tangible goods beyond Earth's atmosphere (or more generally, outside a planetary atmosphere), involving the transformation of raw or recycled materials into components, products, or infrastructure in space, [3] where the manufacturing ...
However, a variety of research labs and organizations have performed a number of tests utilizing human centrifuges to study the effects of prolonged sustained or intermittent artificial gravity on the body in an attempt to determine feasibility for future missions such as long-term spaceflight and space colonization.

The OST treaty offers imprecise guidelines to newer space activities such as lunar and asteroid mining, [131] and it therefore remains under contention whether the extraction of resources falls within the prohibitive language of appropriation or whether the use encompasses the commercial use and exploitation.
An orbital propellant depot is a cache of propellant that is placed in orbit around Earth or another body to allow spacecraft or the transfer stage of the spacecraft to be fueled in space. It is one of the types of space resource depots that have been proposed for enabling infrastructure-based space exploration. [1]
