Space trade refers to the exchange of goods and services between different entities in outer space, such as spacecraft, satellites, and space stations. This emerging market includes activities like mining asteroids for valuable minerals, transporting cargo to and from the International Space Station, and developing commercial space tourism. As technology advances, private companies like SpaceX and Blue Origin are increasingly involved in space trade, making it more accessible. The potential for economic growth in space is significant, with opportunities for innovation in areas like satellite communications and space exploration.
