After a few days the game will let you redo the mission.
I'm not sure what you are asking. The only manned lunar mission that failed was Apollo 13. For why that mission failed visit the related link below.

No, each character's loyalty mission is the only way to gain their loyalty. If you failed Thane's, then there is no way to make him loyal.
If you mean the missions from random people like capturing/killing a thief, returning a horse, help one save his wife, e.t.c., you can just ignore it and it will eventually say mission failed but you won't lose anything. For the main storyline missions, you can maybe suicide, then it'll say retry from checkpoint or exit. You can also kill your own friends or let the enemy run away when they're not supposed to and it'll say mission failed with options retry from checkpoint or exit.
Yes, of course! I went there actually, one time. I met Jaden too. I know, I didn't think he was real either, but I got his autograph, and then dueled him. Which I failed miserably at. Oh, and I met Jesse and Syrus and the rest as well.
