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. Most such concepts would require a considerable long ...
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 authors of the study have developed a neoclassical growth model to investigate the economic transition from Earth-based to space-based mining operations. Their analysis has concluded that a transition from Earth to space mining could facilitate the sustained growth in metal use while concurrently limiting the environmental and social costs ...
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.

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. [62] Optical mining is the term NASA uses to describe extracting materials from asteroids.
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]
[1] It includes terrestrial logistics in support of space travel, including any additional "design and development, acquisition, storage, movement, distribution, maintenance, evacuation, and disposition of space materiel", movement of people in space (both routine and for medical and other emergencies), and contracting and supplying any ...
