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.
The space treaties cover many major issues such as arms control, non-appropriation of space, freedom of exploration, liability for damages, safety and rescue of astronauts and spacecraft, prevention of harmful interference with space activities and the environment, notification and registration of space activities, and the settlement of disputes.
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.

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.
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.
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 ...
