Abstract
With current technological capabilities it is highly unlikely there can be a sustainable private enterprise with its business adventures purely orientated towards space related business endeavors. The costs for a crewed-mission and settlement of Mars will far exceed any potential economic profit that can be generated. If space technology can advance far enough where interspace travel is cost effective, then the potential of Mars resource extraction can make a private space enterprise potentially profitable. There would be the need for public-private relationships for a commercial organization to travel to Mars.
