Why your next interstellar spacecraft might be a repurposed asteroid
In short: Instead of building massive ships from Earth, we could transform celestial bodies into mobile colonies. This video explores how repurposing asteroids offers a smarter, cheaper path to deep space travel by utilizing existing mass for protection and propulsion.
The concept shifts the focus from simple resource mining—extracting water or rare earth metals—to structural transformation. By carving out habitable spaces within carbonaceous asteroids, humans could create mobile cities equipped with ion engines, solar sails, and underground greenhouses. These "flying worlds" would use the asteroid's own mass as a natural shield against cosmic radiation while supporting hydroponic farming and self-sustaining life support systems. This approach facilitates an interplanetary economy featuring orbital refineries and communities that can orbit between Earth and Mars.
