Nevertheless, most of the tech we would need already exists and has been proven out. I personally think the hardest part will be developing the lander and Mars-to-orbit launcher and in-situ fuel synthesis. Both are technical challenges. | |

Getting a pound of stuff back requires bringing 5-10 pounds of stuff there; so a one-way mission costs no more than 10%-20% of a two-way mission of similar size. | |
