Space Riches Developing near space successfully requires developing a huge catalog of marketable space products and services. The material wealth of space is in the minor planets (asteroids, dormant comets, outer rings of Saturn..). We'll want to start by mining near asteroids and stockpiling useful(and marketable) asteroidal materials at L5. As we stockpile and ship materials/items to earth, we mold, cast, assemble, manufacture, and construct just about anything imaginable, including beautiful cities in space. [1 = probably one of the first items we'd offer General Interest Services Electrical energy. [1 SpaceCity Medical Facilities. [1 Spacecraft inspection, repair Includes space welding, initially employed on the Russian Soyuz 6 mission in 1969, and the U.S. demonstrated the feasibility of electron beam welding on Skylab 1 in 1973. Though NASA ended its electron beam welding program in 1996, the technology remains viable.

Includes thermal spray manufacturing, using heat and kinetic energy to melt and deposit material as a coating or structure could be used to coat parts and structures of space infrastructure, or even to form entirely new parts. It could also be used to restore or repair hardware in space. ..... AND free form fabrication, to quickly design and produce replacement parts in space, no longer relying on delivery of new parts from Earth. ..... The environment of space changes the microscopic structure of materials in a number of beneficial ways. Researchers are learning to manipulate fundamental processes such as solidification and combustion to develop greater manufacturing capabilities.

Platinum-Group Metals (Platinum[Pt], Iridium[Ir], Osmium[Os], Palladium[Pd], Rhenium[Re], and Rubidium[Rb]). Used as oxidation catalysts in air pollution abatement processes to remove organic vapors, odors or carbon monoxide. The automotive industry is the principal consumer of PGM as oxidation catalysts in catalytic converters to treat exhaust emissions. The primary medical use of PGM is in cancer chemotherapy. Other medical uses include platinum-iridium alloys in prosthetic and biomedical devices. PGM are good for solar photovoltaic arrays to supply power. Its catalyst properties make it an excellent electrode for fuel cells. Chemical uses include catalysts for organic synthesis, such as hydrogenation, dehydrogenation and isomerization. Rhenium is important in rocket motors as a refractory material, particularly in the form of alloys and coatings. It resists the highly oxidative gases in rocket exhausts. Platinum, palladium and a variety of complex gold-silver-copper alloys are used in dental restoration. PGM can be used as a corrosion-resistant coating. Precious metals. Platinum alloys are used in jewelry. The exact same process used to extract and separate precious metals from the world's largest nickel ore mine at the Sudbury Astrobleme in Canada is easily used in space, and is a simple process using only carbon, sulfur and oxygen, all asteroid derived.
