The future of human exploration in space is uncertain due to the economics of launching humans into space, or sending missions to the Moon or deep space. There are suggestions that there is money to be made in mining asteroids, extracting rare earth elements from the Moon, and performing drug research in microgravity. However, there is a debate over the business cases for these plans. In practice, it is unlikely that anything you could dig up from an asteroid, for example, would justify the cost of sending a mission there. Other potential uses of these technologies include AI data centers in space or space-based solar power, which could be adapted to work in space as the price of doing anything in space decreases as technologies and markets mature. Some of the challenges of space commercialization can be seen in NASA's uncertainty over the future of the International Space Station.
