[@The Spectre] You can indeed, there'll be historical archives and the reason a historian would be awake... support. A lot of people will get it from reading, and ambassador yes for the different people on the ship (Who'll probably look for a civilian leader as well as the military leader)  and first contact.

Family members, it'll really only be if they're viable and then unless they themselves meet the criteria to work on the ship they'd be cryogenically frozen. It'll depend on who you say you're bringing, a healthy 15 year old is a good candidate for a new settlement for example. In terms of how many, maximum (if they meet the criteria) it'd be three. 

You also aren't the latest, there are a couple of more on a different timezone that aren't online yet.
