While DSI is maimly focusing on asteroid observation and mining they are also working on establishing refueling stations for NASA space shuttles between the moon and earth.The future could be permenant establishment on the moon as well as on mars.While a moon base at this time is cost prohibitive there is no telling what might be possible in the next fifteen years at the least.A moon base could provide a stable enviroment in which low gravity experiments could take place as well as helium-3 mining and gold as well.
