Space trade is all goods and services exchanges that are somehow connected to space travel, exploration and colonization.

Several people have considered trade within the Solar System as one of the ways in which the colonization of

s. The asteroid belt is theorized to become a source of valuable ores that may develop into industrial asteroid mining infrastructure, whereas Earth may export hi-tech production. The factor of energy-efficiency of interplanetary transportation may become very important to estimate economic value of a trade route. John Hickman identified the principal obstacle to developing space trade as the distances involved, which will reduce all or nearly all trade to the exchange of intangible goods. That threatens the possibility of conducting business in a genuinely common currency and of enforcing debt agreements incurred by governments. A 2009 article explored tax implications.

Commercial spaceports

Building high-capacity commercial spaceports may require connection with other modes of transportation, such as railroad or sea, which would make spaceports another dimension of national economy.
