Sounds great. I want to see this working on the moon before I trust my life to it.
But the idea of sending unmanned robot ships to carry food and supplies is something to consider, whether or not we call it a one-way trip for the human explorers. We could pre-position everything needed for a couple of years survival, and even pre-position 100% backup, or 300% backup, whether in orbit or in on the ground. When the crew arrived in their ship there could be several shiploads of equipment already there waiting for them. Telemetry could assure the condition of their supplies before they ever leave earth.
If it was me I would want plenty of backup, and the tools for repairs. If it takes 6 months or a year to get parts, you had better have plenty of parts on hand and a machine shop to make what you don't have.
You are not going to go to such lengths just to provide your crew with a Martian retirement home, the point in going is that there is plenty to do, I am convinced they should make subsoil mapping a high priority. That means carrying a lot of specialized equipment along with them. And the tools to fix it.
No one is going to volunteer for a suicide mission, though, and if they would they may not be stable for the long haul in any case. You have to provide a way to get out if everything goes wrong.
Oh, I'm not so sure about that. This world is full of all kinds, and I can imagine people like the characters in the film "Contact" being both qualified and willing.
