Sounds interesting. I'm game, though I have a few questions:

How thorough was the biological survey? Is any of the life incompatible with human life (say, a lichen that causes a fatal allergic reaction or viruses that the human body cannot naturally develop an immunity to due to separate evolution)?

On that note, are there any previous attempts to inhabit the planet such as science stations? Any stations or satellites in orbit? 

Can we get some more specifications on the ships (eg. passenger capacity, crew compliment, 1-way or 2-way, etc.)?

Sorry for all the questions, I kinda know my sci-fi.
