It looks like humankind is getting ready to start its long-delayed expansion in our Solar system. There are ongoing plans for establishing some kind of Moon-based station, for flights in cislunar space and finally, for a manned mission to Mars. There are also efforts to extend the life of the ISS, not to mention the proposed construction of a Chinese space station in the next few years.
If you are a long time SF reader and/or a writer in the same genre, you may have dedicated some thought about how we will work and live outside our planet. In the next few years we’re expecting new manned missions to the Moon and to Mars and it’s a given that we have to leave our cradle someday, to expand in our solar system and beyond.
One of the main problems is about transports, of course. Going to the Moon from our planet is quite costly and energy-consuming, that given the need of overcome the gravity and the resistance of our atmosphere. But what about the Moon or Mars (or any other moon or planet accessible in our system)? If we get to drill mines anywhere or to manufacture any kind of goods out planet, how do we get the stuff home?
